2 The Association of Trace Elements and Vitamins with Lichen Planus: Review Article , Maryam Baghizadeh Fini
Lichen planus is a continual mucocutaneous inflammatory disorder of multifactor nature with numerous clinical symptoms. Nu-merous researchers attribute a key role in disease development to disruptions in the immune system. Appropriate doses of micronu-trients are essential for the immune system to perform effectively. Micronutrient deficiency suppresses immunity by influencing the innate immune system, responses to T-cell mediated and adaptive antibody, resulting in disruption of the balanced host response. Since these trace elements and vitamins have an important role in the immune system and oral lichen planus has a significant rela-tionship with the disturbances in the immune system, the importance of these elements should be considered for each patient. Just several articles examined the hematological anomalies and nutritional imbalances in OLP patients. In this study, all required informa-tion about trace elements and vitamins in OLP patients is obtained.

12 Prosthetic Rehabilitation of Siebert’s Class II Case and Pier Abutments - Case Report , Swati Pustake, Kanchan Bagul, Sachin Chaware, and Preetha Negi
Replacement of teeth with periodontally compromised abutment is a challenge. A tough choice of aesthetics over function is often made by the operator for the satisfaction of the patient. The modified concepts of fixed partial dentures allow one to choose longevity of the prosthesis by not compromising on the aesthetic factors. Ridge defect often leads to a convenient treatment option of removable partial dentures which will not be preferred by the patient. Andrews bridge a fixed removable type of prosthesis is perfect solution for this situation. In long span multiple missing cases Nonrigid connectors have been recommended to reduce the forces as they provide a stress-breaking effect. In this case report, there are two opportunities that allow us to incorporate the modified fixed partial denture technique. Andrews bridge in the lower anterior segment to mask the ridge loss and the posterior long span FPD with a tenon mortise attachment. These two attachments used in this case not only prolongs the life of already compromised anterior teeth but also allows the posterior abutment to remain healthy throughout in long span fixed partial dentures

Objectives: Odontogenic-related maxillary sinus pathologies are identified in cone beam computerized tomography taken for maxillary sinus augmentation and dental implant therapies. The purpose of this study is to determine the prevalence of odontogenicrelated maxillary sinus pathologies among a dental school population. Materials and Methods: Eight hundred and twenty-one patients were retrospectively evaluated for odontogenic-related maxillary sinus pathologies using cone beam computed tomography (CBCT). Age, gender, ethnicity, and dentition status were evaluated to determine potential relationships of the presence of odontogenic-related sinus pathologies. Results: Among 534 CBCT scans, 331 scans presented without sinus pathology bilaterally and 203 scans presented with sinus pathologies in one or both sinuses. 79 scans presented with odontogenic-related maxillary sinus pathologies. The most frequent observations were mucosal thickening. The tooth most frequently associated with pathologic findings were first molars followed by second molars. The findings were higher in males than females (p = 0.006). Age and ethnicity was not a significant factor (p = 0.10, p = 0.05). Dentition status showed root canals (34.65%) were the most commonly associated with pathology. Conclusion: The prevalence of odontogenic-related maxillary sinus pathology was found in 36% of sinuses. Identification and management of odontogenic pathologies are essential to minimize complications. CBCT is highly recommended as a diagnostic tool prior to lateral wall maxillary sinus augmentation surgery and implant placement. Management of odontogenic-related maxillary sinus pathologies need to be tailored to individual patients and involves varying combinations of medical and dental management
20 Coping with the Corona Crisis-Mental Status and Beyond , Aditya Jayan and Gaurav
“Life” as Atharva Veda describes is not merely a sequence of events from birth to death, but also a culmination of various emotions, feelings and frames of mind where it ushers from the cuddling arms of the parents to the burning arms to the funeral pyre! “Lockdown” on the other hand if interpreted aptly is not an act of being imprisoned but a longer period of discipline and an act towards the Nation. Its a test of mindset wherein we are getting to serve our nation without actually doing anything being back at home! Its a persistence of the mindset that we will not go back to normal, normal never was! Our pre-corona existence was not normal other than we normalized greed, inequality, exhaustion, depletion, extraction, disconnection, confusion, rage, hoarding, hate and luck.
21 Maximum Mouth Opening among Saudi Arabian Adults , Fahad Alshammari, Njoud AlSaheel, Najd Alhamzah, Ra’ed Salma and Ahmed Alshammari
Background: The mouth opening range is one of the major characteristics features that different one person from the other. Literature has shown that the maximal mouth opening range varies among different people, ages and regions. On average, a person should be able to fit 3 fingers in an opened mouth. However, differences exist. Aim: To set a reference measurement for maximal mouth opening in Saudi Arabian adult population. Methods: The study was conducted on patients attending dental clinics in Riyadh, Kingdom of Saudi Arabia. The maximum mouth opening (MMO) was recorded for adult patients using a ruler. The patients were requested to open their mouth at maximum level and the length between the maxillary central incisor edge and the mandibular central incisor edge in the same side of the mouth was measured. Correlation of the mouth opening with age was determined using a Spearman correlation matrix. Besides, Kruskal Wallis and Mann Whitney tests were used for comparing the continuous variables. Conclusion: The conclusion obtained from the findings is that the males mean maximal mouth opening of an adult was significantly higher than females in Saudi. A negative correlation suggesting that mouth opening decreases with age. Results: The maximal mouth opening mean ± SD of the participants was 50.1 ± 6.3 mm. Mean ± SD maximal mouth opening for males (52.5 ± 6.3 mm) was statistically significantly higher than females (47.8 ± 5.3 mm) (p < 0.05). Spearman’s test between maximal mouth opening and age showed a negative correlation of p > 0.05. No statistically significant difference was found between the mean ± SD maximal mouth opening and age groups (p > 0.05).

24 Non-Surgical Management of Unusually Large Chronic Recurrent Periapical Abscess and an Insight on Periapical Radiolucencies , Swati Gupta, Ramakant Gupta and Manju Gupta
Recurrent inflammatory periapical lesions are commonly encountered oral pathologies. The usual cause of these periapical lesions is endodontic in nature and can be easily treated by endodontic treatment. They exhibit wide biologic behaviors and their presentation as recurrent pus discharging ulcers can lead to patient’s apprehension and even be cause for clinician’s anxiety. This is because many non-endodontic causes may also lead to periapical lesions. A thorough knowledge about them therefore, is crucial for clinicians not only to properly diagnose and manage such cases, but is also important to safeguard themselves from patient’s evil intentions of making easy money by claiming refund. The present case is one such example where unusually large chronic recurrent periapical abscess was managed with non- surgical endodontic treatment. With this case report, authors intend to discuss the different periapical radiolucencies and explain scientific guidelines for their adequate diagnosis and management.

34 Utility of Sodium Tetradecyl Sulphate for the Management of Oral Venous Malformation , Krishna Kishor, Shiv Kishor, Heera, Hiralal Ash, Kumar Arunesh and Sudarsan Sen
Venous malformation are one of the most common lesions of oral cavity. The lesion may be congenital malformation in neonates or arteriovenous malformation in adults. Various surgical and medical managements are possible for vascular lesions which includes surgical excision, laser therapy, cryotherapy, selective embolization, intralesional sclerosing agents, beta blocker and steroid therapy. In this current study we assessed the efficacy of intra lesioned injection of sclerosing agent i.e. 3% sodium tetra decyl sulphate in oral lesions of venous malformation. Sclerotherapy with 3% sodium tetra decyl sulphate is an effective agent in treating benign oral lesion of vascular malformation and provides alternatives to surgical method.
35 Synergistic Effects of Cordycepin and Genistein on Preosteoblast MC3T3-E1 Cells with Endoplasmic Reticulum Stress , Jiaxuan Lu, Xin Luo and Xiting Li
Endoplasmic reticulum (ER) stress activation disturbs bone homeostasis and plays an important role in osteolytic bone diseases development. Cordycepin (3'-deoxyadenosine), a natural structural analog of adenosine, possess multiple pharmacological activities and exerts osteoprotective effect. Genistein can be used as protectors or synergists of adenosine drugs. The aim of the present study was to investigate whether the combination of cordycepin (Cor) and genistein (Gen) regulates proliferation, migration and differentiation of preosteoblast MC3T3-E1 cells in a tunicamycin (TM)-induced acute ER stress model. Cell viability were assessed using cell counting kit-8 (CCK-8) assay and osteoblast migration were evaluated by transwell chamber assay. The differentiation was assessed by alkaline phosphatase (ALP) staining assay. qRT-PCR assay was performed to confirm the establishment of ER stress model and to measure the mRNA level of key molecules involved in osteogenic differentiation. Exposure to the combination of 10μM cordycepin and 10μM genistein had no cytotoxicity in MC3T3-E1 cells, but increased the number of proliferative cells after pretreatment with 2 μg/ml TM. Analogously, ER stress-induced suppression on MC3T3-E1 cells migration was restored to control levels by the administration of cordycepin and genistein combination. Cordycepin and genistein combination significantly up-regulated ALP activity of MC3T3-E1 cells in TM-induced ER stress model. The qRT-PCR data demonstrated that the combined treatment effectively accelerated osteogenic differentiation by enhancing the mRNA level of differentiation markers including collagen type I, ALP, BSP and OPN. These results reveal that the co-administration of cordycepin and genistein exerts synergistic osteoprotective effects and has the potential to serve as a host risk reduction strategy for osteolytic bone diseases associated with ER stress activation.

Background: One of the main uses of CBCT is the design of implant therapies, and linear calculations in these therapies are important in quantifying bone (height and width). However, previous researches have all been conducted on dry skulls and no research has been performed in patients' clinical conditions. Aim of the Study: The aim of this research was to determine the correlation between CBCT linear measurements and actual measurements during surgery in patients undergoing implant surgery. Materials and Methods: In diagnostic research, 54 patients were selected for implant treatment in the premolars and the distance of the mental foramen to the apex of the ridge was measured using a caliper during surgery. The same calculations were repeated in CBCT images with Romex is software by two observers at two 2-week intervals. The difference in bone height calculations in CBCT images and actual measurements during surgery were analyzed by repeated values and ANOVA. Results: The difference in absolute value of bone height in CBCT images (second observer) and its actual values was 0.811 ± 0.54, 0.894 ± 0.67 between the first observer and its actual values,0.871 ± 0.63 between the first observer in the next 2 weeks later and the actual values,0.804 ± 0.57 between second observer in 2 weeks later and its actual values. The mean difference of bone height observations by 2 observers in 2 weeks from its actual values was equal to 0.0 ± 828.89 mm. No significant differences were observed between the absolute magnitude values of bone height measurements in CBCT images and their actual values at the time of surgery after exposure. Conclusion: Given the limited bone height difference in CBCT images from its actual values, this imaging modality appears to be a useful and accurate tool for estimating bone height in implant surgery in clinical settings.
37 Intraoperative Anatomical Surface Marking and Cone Beam Computerized Tomography for Assessment of the Hamulus in Palatoplasty by Younger Cleft Surgeons , Bergonzani M, Uy V, Zeinalddin M and Lotha B
Understanding the surface anatomy markers for the hamulus in palate surgery is often a useful pointer to the position of the hook of hamulus during cleft palate surgery. This innovative idea is of particular use in Veau 1 and 2 where only medial incisions are used. Younger cleft surgeons feel more comfortable when they are able to clearly see palate structures during careful dissection. Using the intraoperative method of marking out the position of the hamulus makes the whole process of identifying the hook of hamulus a lot simpler. Drawing a vertical line from the mid tuberosity which intersects a horizontal from the level of the posterior spine, the hamulus which lies a few mm below and medial to the intersection, can easily be found. We divide each region into clockwise zones 1, 2, 3, 4 and found the position to be consistent in zone 4, slightly medial and below the intersection of the two lines. This finding was also noted on cone beam CT images of adult and pediatric palates.

42 Legal Validity of Criminal Identification from the Comparative Analysis of Bitemarks , Joana Mancellos, Maria Inês Guimarães and Joaquim Gonçalves
Human bitemarks are normally associated with violent crimes, and when recorded, they can be the basis for the constitution of forensic evidence in a legal context. The recording and the comparative analysis of these marks, allied with data on the suspects, enable the elaboration of forensic reports that lead to the exclusion or non- exclusion of suspects, and they also contribute to the unfolding of a criminal proceeding in which the court is responsible for issuing a sentence to a defendant. The legal validity of the comparative analysis of bitemarks in human identification is a widely discussed topic in the scientific community. The numerous publications on this subject reveal different opinions regarding its contribution in crime situations and whether or not it is legally valid. The objective of this literature review is to determine the legal significance of bitemarks in the identification of criminals, considering the methods used to study bitemarks and the reliability of their results.

48 A Case of Sinonasal Lymphoepithelial Carcinoma Presenting as a Palatal Swelling , Nikolaos Kolomvos, Dionysios Kyrmizakis, Evangelia Piperi and Evanthia Chrysomali 
Lymphoepithelial carcinoma is a rare type of undifferentiated carcinoma, characterized by atypical epithelial cells surrounded by a reactive lymphoplasmacytic infiltrate. We report a case of sinonasal lymphoepithelial carcinoma arising in the left maxillary sinus in an 80-year-old Caucasian male patient. The lesion had invaded the adjacent lateral wall of the nasal cavity appearing on the palate as a painful swelling. There was no evidence of tumor involvement from the nasopharynx and larynx assessment and no swollen cervical lymph nodes were noticed on the head and neck imaging examination. An incisional biopsy from the oral cavity, as well as an endoscopic biopsy of the neighboring nasal mass were performed. The histopathological and immunohistochemical analysis of both specimens showed identical features and a common diagnosis of sinonasal lymphoepithelial carcinoma was rendered. In conclusion, oral swellings located on the palate may be associated with maxillary sinus malignancies. Thus, the clinician should include in the differential diagnosis not only primary oral carcinomas, but also malignant neoplasms arising from neighboring anatomic sites.
49 Role of Human Papilloma Virus (HPV) in Potentially Malignant and Malignant Lesions of Head and Neck , Paramita Ingle, Basavaraj Bhagawati and Meenal Jethlia
The sixth most common cancer diagnosed worldwide are head and neck cancer (HNC). In 2008, 633,000 new cases were diagnosed out of which 355,000 cases resulted in mortality. Early detection of precancerous lesions remains a challenge to clinicians. In 1983, evidence of Human Papilloma Virus (HPV) infection was identified in a subset of oropharyngeal carcinomas (OPC). Thus, confirming HPV as a causative agent in HNC. HPV is now recognized as an important risk factor for the development of oropharyngeal cancers, and results of previous studies have demonstrated epidemiological and molecular evidence of the presence of the HPV genome in pre-malignant oral lesions in SCC tissues, especially of the subtypes of HPV-16 and -18. There is close to no evidence linking HPV to carcinoma. However, this review focuses on the role of HPV in oral oncology and to comment on the HPV DNA reported frequencies potentially malignant oral lesions

52 Treatments for Paresthesias after Orthognathic Surgery: Literature Review , José Victor Marconato, Luis Eduardo Genaro and Paloma Fernandes
Orthognathic surgery is a procedure of choice for the treatment of skeletal deformities; however, it is common to observe a change in sensitivity called paresthesia, in cases where the nerves are injured. For the patient's sensitivity to return, it is necessary to perform treatments such as the use of low-power laser, acupuncture and drug treatment. This work sought to identify these treatments and describe them, in order to guide the clinical management of dental surgeons.
53 Comparing the Anxiety Level between Myofascial Pain Dysfunction Syndrome Patients and Others , Sara Pourshahidi, Hooman Ebrahimi and Zahra Pourabdollah
Myofascial pain dysfunction syndrome (MPDS) is the most common temporomandibular disorder and a psychophysiologic disease that primarily involves the muscles of mastication and can cause pain, mouth opening limitation, mandibular deviation during mouth opening and closing and tenderness of one or more masticatory muscles or tendons. Among various ideas about the etiologic factors of MPDS, two main reasons are occlusal disorders and mental health problem. More researches recently, focus on mental health problem as the main and initial factor of MPDS. Anxiety is one of the most fundamental psychological problem that exists in almost all societies, it increases muscle’s tonisity and thus leads to pain. Considering the high prevalence of anxiety in patients suffering from this syndrome, this study is to investigate anxiety intensity in these patients and compare that with two control groups. The first control group were 30 patients who referred to dental school because of any problems except MPDS, and the second one included 30 Shiraz citizens. All three groups were informed about the procedure of the study and then completed Spielberger Anxiety Intensity Questionnaire, that had been validated before. Then a psychologist checked and graded the questionnaires. Using spss v.15 we analyzed the data with ANCOVA and Chi-Square tests. This study demonstrated that the MPDS patients had more anxiety than the common people of the society. The significant point in our study was the comparison of anxiety level in MPDS patients with the other patients that referred to dental school with a reason other than MPDS which revealed no significant statistically difference. According to this result, we can say that the high anxiety level in MPDS patients may be not related to the disease and can be due to the situation they share with others who refer to dental school, so the anxiety may be the result of their disease and not the cause.

56 Contracted Endodontic Cavity in a Severely Calcified Anterior Tooth Using Guided Endodontics Technique: Case Report , Alessandra Rosa de Sá, José Flávio Gabrich Giovannini, Henrique Trindade de Magalhães, Victor Couto Figueiredo, Tiago Braga and Rodrigo Rodrigues Amaral
Pulp canal obliteration (PCO) is characterized by the deposition of calcified tissue within the root canal space, which may partially or totally involve the canal. The endodontic treatment of calcified teeth is considered a challenging task depending on the severity of pulp obliteration. Recently, guided endodontics has become an alternative approach for those cases. This case report describes the use of guided endodontic access for the maxillary left lateral incisor of a 73-year-old male patient that required restorative treatment. The tooth had an extensive coronary fracture and demanded endodontic treatment for prosthetic purposes. Periapical radiography showed that pulp obliteration was severe at the cervical and middle thirds of the root. A cone beam computed tomography (CBCT) was requested in order to assess the level of obliteration. A three-dimensional (3D) template was planned with the CBCT's images along with intraoral scanning. A prototyped guide for guided endodontic access was performed, and the dental procedures were concluded safely. Guided endodontic access was paramount to overcome the pulp obliteration and ensured the endodontic treatment, and prosthetic rehabilitation could be performed.

64 Advanced Diagnostic Aids in Detection of Potentially Premalignant Oral Epithelial Lesions - A Review   , Jayanta Saikia, Balaji Pachipulusu, Poornima Govindaraju and Bhagyashree M Nair  
Oral cancer is one of the most mutilating disease afflicting mankind. Precancerous lesions, conditions and early stage oral cancer cannot be adequately identified by visual inspection alone and may be easily overlooked and neglected. Differentiation between early stage cancer, precancerous lesions and benign lesions is often difficult because of the similar appearance of the lesions. Surgical biopsy is a gold standard for diagnosis, but this needs professional services, which are impractical at times. Alternative screening methods which are non-invasive, easily performed and highly accurate are the norms for any test to accept as an alternative for histopathology

In this article we reviewed two different approaches of treatment, side effects of RME and also the non-surgical mini screw assisted expansion in both older and younger patients. The stability of expansion, skeletal and dentoalveolar effects in both treatment approaches were reviewed.
71 Combating COVID-19: A Dentist Perspective , Pranjali V Bawankar, Abhay P Kolte and Rajashri A Kolte
The current scenario in the world is awfully perilous and insecure because of the world pandemic of COVID- 19.Healthcare workers (HCW) are frontline warriors for prevention and treatment of Coronavirus affected patients. Face-to-face communication and consistent exposure to body fluids such as blood and saliva predispose dental care workers at serious risk for 2019-nCoV infection. As demonstrated by the recent coronavirus outbreak, information is not enough. During dental practice, blood and saliva can be scattered and aerosol production is common. Accordingly, dental practice can be an impending risk for dental staff, and there is a high risk of cross-infection. This article deals with all information collected to date on the virus, in accordance with the guidelines of international health care institutions and provides a comprehensive protocol for managing possible exposure to patients or those suspected of having coronavirus.
72 Attachments in Cast Partial Denture: A Case Report , Swapnita Vaity, Omkar Shetty, Gaurang Mistry and Manali Mehta
Retention of prosthesis is one of the key factors in the success of the prosthesis. Apart from retention, one of the major concerns in removable partial dentures has been stress transfer on the remaining tissue; particularly in distal extension cases. The use of attachment gained momentum in around late 1950s after considerable efforts by Steiger and Boilet. The need for extra retention and improved esthetics, lead to the development of intra-coronal and extra-coronal attachments. Attachment is a mechanical device for fixation, retention, and stabilization of prosthesis. The criteria that help in the selection of the attachments are location, function, retention, space and cost factors. The article presents a case report on attachment in cast partial denture.
73 Transfloral Acupuncture - A New Combination of Ear Acupuncture and Floral Essences to Improve the Energy of Patients , Andreas Wirz-Ridolfi
In any patient the extension of the actual electromagnetic field is decisive for his state of health as well as for the effectiveness of any therapeutic measure. With the innovative method of Transfloral Acupuncture it is possible to improve the energetic level of patients considerably within seconds. Most foci (which are obstacles for diagnosis and treatment) are dental foci. Teeth, even if they don't yet need treatment by a dentist, can present a focus causing a considerable loss of energy for the patient. This loss of energy reduces his capability to react to treatment as well as his immune system. According to the research of Prof. Frank Bahr and Dr. Heike-Dorit Schmid every tooth is in resonance to a flower essence, (Bach, Californian flower essences or Australian Bush flowers). By means of the Vascular Autonomous Signal (VAS) and the Bahr detector (a combination of a 3-Volt hammer and a black and white hammer) all teeth are controlled and the corresponding flower essence is chosen. A drop of the floral essence is given orally and another drop is placed on the ear lobe of the patient at the place of the tooth found to be a focus. Now a permanent needle is inserted through the floral essence into the ear lobe

Traumatic injuries to dentoalveolar tissues are considered the most serious oral health problem amongst children and adolescents Epidemiological studies revealed that children from 8 to 12 years often suffer a dental injury. It may vary from minor tooth fracture to extensive dentoalveolar damage that involves the supporting structures and avulsion. Avulsion is defined as total dislodgment of the tooth from its socket. It represents about 16% of all traumatic dentoalveolar injuries (TDI). Central incisor is the most affected tooth due to their labial projection which make them more susceptible to facial trauma.
75 Endodontic Management of Trauma-induced External Root Resorption Following Orthodontic Treatment by Placement of Biodentine: A Case Report , Reza Sayyad Soufdoost, Ali Jamali Ghomi, Hossein Labbaf and Homeira Ansari Lari
External root resorption is considered as a frequent complication of orthodontic tooth movement, particularly, in a tooth with the history of trauma and resorption. Advances in dental material science not only have increased demand from the patients for saving their teeth, also have enabled clinicians to treat the complicated cases. Previously most of the teeth with severe external root resorption were scheduled to extraction due to poor prognosis of conventional endodontic treatment. This case report presents successful nonsurgical endodontic management of a trauma-induced perforating external root resorption with Biodentine which had been progressing rapidly after applying orthodontic forces. 24 months follow-up revealed arrest of root resorption, and advanced healing of the lesion
76 Intraosseous Odontoma Erupted: Diagnosis and Treatment , Estefanía Raquel Fernández, González María M, Barrios Evelin E and Krupp Sebastián
Odontoma is the most frequent benign odontogenic tumor in the oral cavity, especially in the anterior sector of the maxilla, with a greater predominance in men in a 1.5: 1 ratio, diagnosed between the first and second decades of life. It is a pathology where the dental tissues are normal, but its structure is disorganized. Regarding the etiology, it is related to trauma, morpho differentiation, genetic disorders and Malassez remains.

88 Binder’s Syndrome: The Need of an Ortho-Surgical Approach , Priti Shukla, Amit Nagar and Rachit Thakral
Despite the frequent presence of all characteristic orofacial features and profound dental malocclusions there is very little to be found in the literature of maxillofacial surgeons to diagnose a case of Binder syndrome or also known as maxillo-nasal dysplasia or maxillo-nasal dysostosis. Nordenram., et al. recommended to delay any definitive orthodontic treatment in individuals with this syndrome up to the time when growth has ceased. For severe cases they also advise for grafting in the nasal area along with Le-Fort I and II osteotomy. Thus, in such cases the orthodontic treatment should go hand in hand with the surgical team hence opting for an ortho-surgical approach. The aim of the orthodontist in the post-surgical phase should be improvement of facial beauty, relieve crowding of the arches and their co-ordination and to obtain a Class I molar relationship.

121 Overview of Various Angled Abutments Commercially Available: A Review , Kothuri Naga Ravalika, Rahat Aisha Yasmeen, N Chandra Sekhar, Kollipara Soujanya and Valliammai Rajendran
The utilization of implant‑supported crowns and bridges has become a well‑established and preferred approach in treating com‑ pletely and partially edentulous states. An ideal implant position is requisite for obtaining good esthetic results and correct emer‑ gence of screw access hole. Commonly, due to insufficient bone volume, implant will be placed in available bone which leads to unfa‑ vorably placed implants. Once placed, such implants are restored by giving a cement‑retained prosthesis to avoid labial/buccal screw access holes witch are esthetically unpleasing. In such a scenario, a graftless solution would be using an angulated screw channel technology which tilts the prosthetic screw access hole emergence in a desirable direction that is more esthetic and acceptable. Angu‑ lated abutment system is unique and exclusive and are designed through computer‑aided design and computer‑aided manufacturing technologies. This system rectifies angulation issues with millimetric precision with full freedom of movement. This review article presents an overview of various types of angulated abutments commercially available. It highlights the features and angulation provi‑ sion of various commercially available angulated abutments.

123 Accidental Dislodgement of Separated Instrument in the Maxillary Sinus: A Unusual Case , Avisha Agrawal, Pratima Shenoi, Rajesh Kubde, Snehal Sonarkar, Gautam Badole, Vandana Kokane, Ankita Ramteke and Purabi Edbor
Root canal therapy consists of a cascade of scientifically-based technical procedures. Failure to follow the standard protocols and lack of knowledge can lead to a number of iatrogenic accidents which are collectively called “endodontic mishaps”. One of the most frequently encountered endodontic mishap is a separation of the endodontic instrument. Heroic attempts to remove separated instrument may lead to dislodgment of instrument in the periapical area. At times such instrument get dislodged in the maxillary sinus when treating upper maxillary molars and canines. Separated instrument in maxillary sinus, irrespective of their origin or nature, act as foreign body and Such objects should normally be removed at the earliest in order to minimize the likelihood of maxillary sinus complications. Studies have shown that some of the objects can cause chronic sinusitis because of the invasion of the sinus by highly virulent bacteria, while some remains asymptomatic. It is an uncommon finding to observe, an asymptomatic dental endodontic instrument in a position so close to the maxillary sinus without any oro-antral fistula formation and/or sinusitis attacks. This paper presents the case of a separated endodontic instrument which was pushed inadvertently in the maxillary sinus of a 41-year-old female patient

133 Hospital Dentistry: Dentist's Performance in the Pediatric Sector , Alexandre Ramos Braga
Hospital Dentistry is a dental specialty that aims to perform oral care and procedures in the hospital environment. Child hospitalization is considered a traumatic experience that leads the child to different feelings, such as anguish, anxiety and fear. The child will have to deal with different and noisy environments, lights, constant routine procedures, exposing him to great stress. The dentist's role in this context becomes very important, being part of the multidisciplinary team. The dentist, in the condition of examining children in a hospital environment, verifies the real need and the best opportunity to intervene in the oral cavity in order to maintain their healthy clinical condition as a whole. General health may be at risk if oral health is compromised, which can interfere with the recovery process. Treatment should include all dental specialties, considering a patient's clinical condition. The patient can be submitted to emergency procedures in the case of trauma and preventive procedures when the systemic condition worsens or is not affected by hospital infection

139 Healing of Periapical Lesions with Conventional Root Canal Treatment: A Case Report , Nayantara Sud
Infected pulp tissue is the major cause of periapical lesions, a majority of which are granulomas, radicular cysts or abscess. These lesions can only be diagnosed histologically. Root canal treatment or non surgical endodontic treatment is the treatment of choice in these cases without surgical intervention. Healing after the non surgical treatment takes place in about one year. In non surgical treatment emphasis is laid on thorough debridement, disinfection of the root canal system and obturation of canals. There are higher rate of healing in the anterior segment as compared to the posterior segment. The periapical index (PAI) is widely used measure to know the status of the periapical tissues. Thus, conventional endodontic therapy in combination with calcium hydroxide as an intracanal medicament contributed effectively in healing of periapical lesions in these cases.

150 Inflammatory Pathology of the Oral Cavity: Relevance in Oral Oncogenesis , Teresa Sequeira, Gonçalo Sousa, Eurico Monteiro and Augusta Silveira
Oral cancer is considered to be a growing public health problem and within head and neck cancer pathology, it is the most common. It is the 6th most common cancer in the world, corresponding to approximately 3% of all cancers. Despite the dedication and investment in this pathology, the advances in diagnosis strategies and the development of early intervention programs and treatments, aimed to be more targeted, more effective and less aggressive, the global survival rate after 5 years has remained worldwide at approximately 50% over the last three decades. The evaluation of Quality of Life stands out in this context as a key indicator, along with survival. We aim to review oral cancer etiology and discuss inflammation role in oral oncogenesis, considering its potential to modulate and amplify the impact of known risk factors. Additionally, we point out inflammation as predictive of poor prognosis in patients with oral cancer or at risk of developing it. Articles were collected from the PubMed, Bon, Elsevier, Science Direct databases, considering mainly the last 5 years of publication (2015 to 2020). The indexing terms used were “oral oncology and risk factors”, “oral oncology and epidemiology” and “inflammation and oncogenesis”. The role of the immune system and inflammation in the initiation, promotion and progression of oncologic pathology of the oral cavity has deserved maximum attention from the scientific community. It is clear that the presence of pro-inflammatory factors associated with immunosuppression are closely related to oral oncogenesis and poor prognosis. The chronic inflammation can contribute to modulate and amplify risk factors actions.

The World Health Organization (WHO) has identified 150 systems of alternative medicine, out of which the most practiced ones are Ayurveda, Homeopathy, Naturopathy, Unani, Magneto therapy, Aroma therapy, Yoga, Massage therapy, etc. The alternative medical systems involve Western culture (Homeopathy and Naturopathy) and Non-Western culture (Ayurveda and Chinese medicine). We know that stress is a major causative factor for various psychosomatic disorders and oral diseases which can be prevented by holistic approaches. Many oral mucosal lesions like aphthous stomatitis, lichen planus, OSMF, leukoplakia, radiation mucositis have yielded great results for healing by the use of plant extracts. Even though the treatments are usually of longer durations, are unconventional and often lack errors in reasoning, but have yielded positive effects on various individuals. This paper emphasizes on the use of alternative medicine in dentistry

Cariogram assessment was performed for each patient at baseline, 3 months and 6 months to obtain the caries risk percentage for each patient at the different time intervals.
164 Bone Necrosis After Pulp Treatment of Temporary Molar with Calcium Hydroxide: In Vivo Confirmation , Cristina Cardoso-Silva, Maria Llanes and Elena Barbería
Calcium hydroxide has been used for a variety of purposes in dentistry including pulpotomy of temporary molars. Several studies examining inflammatory response to its use generally demonstrated a mild inflammatory reaction. However, it may cause adverse reactions damaging bone and soft tissues either by direct contact after poor implementation or after ion diffusion. The severity and extent of the lesion depends on the quantity and concentration used, as well as on the time of contact. The following report describes a case of bone necrosis after a pulpotomy with calcium hydroxide in a temporary molar. Pathological analysis confirmed de diagnosis
165 Dental Calculus – Mere Ash Heap or Still A Mystery: A Review of Literature on Etiologic Significance of Dental Calculus , Swati Gupta, Ramakant Gupta and Manju Gupta
Chronic inflammatory periodontal diseases i.e., gingivitis and periodontitis are one of the most common afflictions faced by the human beings. They are considered to be infectious in nature having polymicrobial etiology. Dental plaque, which is a pool of these disease causing microorganisms has been the focus of researchers for the long time, and is considered to be the primary etiologic agent in disease etiopathogenesis. However, dental calculus which is a mineralized product of this plaque remains ignored and is considered merely as an ash heap of minor significance in etiopathogenesis of disease. Even though, there literature evidences of presence of intact and viable bacteria within the non- mineralized channels and islands in supragingival calculus from various studies. However, viability of bacteria in dental calculus and their role in disease pathogenesis still remained obscure. Therefore, this review intends to collate all the available literature and present the studies related to etiologic significance of dental calculus and investigation of the viability of bacteria in dental calculus along with their identification at one place and provide a way forward towards better understanding on etiopathogenesis and treatment of periodontal diseases

168 Monomorphic Adenoma: A Diagnosis or a Misnomer? A Review of Literature on Terminologies, Features and Differential Diagnosis of Basal Cell Adenoma , Swati Gupta, Ramakant Gupta and Manju Gupta
Basal cell adenoma, previously was termed by few authors as Monomorphic adenoma. The term “Monomorphic adenoma” was originally proposed for any benign epithelial salivary gland tumour other than benign mixed tumors. Monomorphic adenoma included tumours such as Warthins tumour, basal cell adenoma and canalicular adenoma. However, in the new 2005 WHO classification of salivary gland tumours the term “monomorphic adenoma” is not included and basal cell adenoma is considered as a separate entity. This paper intends to discuss the controversies regarding the terminology and classification of monomorphic adenoma along with diagnosis and differentiation of basal cell adenoma from other tumours

The aim of the study was to evaluate the effect of enlargement of the apical one third of root canals; by using F4 in comparison to F3 Protaper files; on the amount of Enterococcus Faecalis and surface irregularities in the apical third.24 freshly extracted human single canalled premolars were obtained. The root lengths were standardized to 15 ± 1 mm. The root canals were instrumented up to #20 K-file till the apical constriction for standardization. Following root canal preparation and sterilization, all root canals were completely filled with 30µ E. faecalis suspension and incubated at 37°C for one week with refreshment every 48 hours. All teeth were sampled after bacterial injection and before instrumentation for examination of bacterial presence inside the canals. For the apical one third assessment, Scanning Electron Microscope "SEM" was used to examine the surface irregularities.The results concerning bacterial reduction revealed that Group II (F4), showed a significantly higher E. faecalis reduction than Group I (F3) (P = 0.025). However, none of the preparation sizes rendered a bacterial free root canal system. Topographic surface analysis revealed that group II (F4) had significantly lower surface irregularities in comparison to group I (F3) (P = 0.036).

172 The Authentic Inbred Sheath - “The Immunoglobulin" , Santhi Gorle, Srikanth Adusumilli, Rukmini Jyothirmayee Jakati, Rani Ponnaganti, Sahithi Valluripalli and Sanjeev V Jakati
Humans have developed a highly specialized defense mechanism system due to continuous stimulation by foreign material from the environment. Immunoglobulins are unique structures in the body which is synthesized by plasma cells and, to some extent, by lymphocytes. They have a significant role in recognizing and protecting the body against foreign material, either present freely in the body fluids or attached to cell surfaces. Besides the plasma, immunoglobulins may be identified in other body fluids or tissues such as urine, spinal fluid, milk, saliva, tears, lymph nodes, and spleen.

180 Intimate Partner Violence Prevention: Moral, Legal and Healthcare Algorithms , Joana Braamcamp de Mancellos
“Gender inequality” and “gender-based violence” are paradigms that one hope would be extinct by the 21st Century, two cultural concepts that our society tries to disguise as dated, but that still exist in the form of intimate partner violence in developed countries. In this literature review, intimate partner violence is described as a serious public health issue with high occurrence rates across the world, which requires an urgent implementation of protection and prevention measures.The extensive study of contents resulting from a search with the terms “intimate partner violence”, “domestic violence”, “preven-tion”, “violence against women”, “abuse”, “IPV” and “crime” allowed to gather information on preventive measures and integrate updated statistics of the World Health Organization (WHO) and of the Portuguese Association for Victim Support (APAV).The measures of protection and prevention of this type of crimes demand a change of moral and legal behaviours around the globe, as well as the implementation of algorithms of functional performance that can be applied by health professionals at patient-directed services. In this literature review, we will present the “RESPECT”, “AVDR” and “HELP” algorithms.
181 Leave no Tooth Behind - A Retreatment Case Report , Reaba Rebecca Thomas, Aby John, Shashi Rashmi Acharya and Archit Kedia
In a dental practice, it is becoming increasingly common to have endodontic cases which are seen to fail. The spike in the number of endodontic treatments carried out has consequently led to the increase in the number of failures seen and complications in their management. Endodontic retreatment is favored over dental extraction due to the desire to preserve the tooth and prevent adverse consequences in terms of functional and psychological effects that the loss of a tooth would have on a patient. This article showcases a clinical case that required endodontic retreatment to combat any complications that could arise and lead ultimately to the extrac-tion of the tooth. Considering that the tooth in question has a special importance with a physiognomic role, we resorted to its end-odontic retreatment and we have covered it with a porcelain fused to metal crown.

184 Evaluation of P53 in the Expression of Odontogenic Keratocysts , M Bousserouit and S Chbicheb
The odontogenic keratocyst also called epidermoid cyst, was first described by Philipsen in 1956; it develops at the expense of remnants of the odontogenic epithelium included in the maxillae. It is characterized by a large keratinization of its squamous border, aggressive growth and a strong propensity for recidivism. After the root cyst and the follicular cyst, the odontogenic keratocyst is the most common cyst of the maxillae.The odontogenic keratocyst has been a widely studied patholo-gy with a continually changing nomenclature of a "primordial cyst" to "odontogenic keratocyst". The aggressive nature of this unique jaw pathology has kept it in the limelight since its discovery with documented cases of cortical erosion, soft tissue involvement and extension in the skull base, orbit and infratemporal fossa. It's been a topic of debate for a long time, if the cysts could be as aggressive as this pathological entity.

187 A Journey from 3D to 4D in Orthodontics – A Review Article , Mamta Phogat and Tulika Tripathi
Orthodontic records are one of the main milestones in orthodontic therapy. Records are essential not only for diagnosis and treat-ment planning but also for follow-up of the case, communicating with colleagues, and evalu¬ating the treatment outcomes. Various 3D techniques such as such as Computerized Tomography (CT), Cone Beam Computerized Tomography (CBCT), Micro Computerized Tomography (MCT), 3D laser scanning, structured light technique, stereophotogrammetry or 3D surface imaging systems (3dMD), 3D facial morphometry (3DFM), Tuned Aperture Computed Tomography (TACT), and Magnetic Resonance Imaging (MRI) has cre-ated the potential for comprehensive facial evaluation. Recently, with the emergence of 4D a new dimension (motion) has been added to the imaging filed which has enabled capturing of dynamic facial movements. However, more elaborative and interdisciplinary research work needs to be done to explore the scope of 4D techniques. Therefore, the aim of this study is to review advances in 3D and 4d imaging with in the field of orthodontics.

The purpose of this study was to establish normative values of soft tissue profiles in Nepalese adults, to compare the data obtained with those of caucasian adults using Cephalometric for orthognathic surgery (COGS) analysis (Legan - Burstone); also to identify possible sex differences between Nepalese young men and women.
200 A Comparison between the Antibacterial Activity of Propolis and Ginseng Extracts on Porphyromonas gingivalis and Prevotella intermedia Isolated from Patients with Chronic Periodontitis , Heba A Shawky and Walid A Lotfy
The antimicrobial activity of ginseng extract was investigated in-vitro against 24 clinical isolates of Porphyromonas gingivalis and Prevotella intermedia. To our knowledge, there is a lack of researches on the evaluation of the antimicrobial effectiveness of ginseng extract on periodontopathic bacteria. We also compared the in-vitro antibacterial action of ginseng extract to that of propolis extract by agar diffusion method. The MIC values of ginseng extract against Porphyromonas gingivalis and Prevotella intermediawere 512 and 1024μg/ml, respectively. While the MIC obtained for propolis extract were 256 and 512μg/ml against Porphyromonas gingivalisand Prevotella intermedia,respectively. Moreover, the statistical analysis for the effect of ginseng and propolis extracts on Porphy-romonas gingivalis and Prevotella intermedia using student paired t-test revealed a significant difference between the two groups (p< 0.001). However, the anti-Porphyromonas gingivalis and anti-Prevotella intermedia mean activities of ginseng extract were lower than that of propolis extract by 1.32 and 0.17 AU, respectively. The results of the current study support the usage of ginseng extract as an adjuvant to periodontal therapy after proper in-vivo studies are performed.

Ameloblastoma is a neoplasm originating from the odontogenic epithelium. The tumor is considered benign despite its locally invasive nature. The pathogenesis of ameloblastoma involves the origin of the tumor from one of the following sources: remnants of dental lamina or remnants of the Hertwig’s epithelial root sheath, basal cells of the oral mucosa, developing enamel organ, and epithelial lining of an odontogenic cyst. It can exhibit different clinico-radiographic presentations such as conventional, unicystic and peripheral. Ameloblastomas occur most predominantly in the posterior mandible, in the molar-ascending ramus area, and are quite uncommon in the anterior jaws. Third to seventh decade is the usual age range for the occurrence of ameloblastomas with no gender predilection. A case of ameloblastoma which occurred in the anterior mandible of a 24-year-old female patient is presented. The clinico-pathological features, diagnostic criteria, and management of the case are discussed. The case is important because of its unusual presentation in the anterior region of the mandible and the diagnostic challenge it posed during the initial investigation.
204 Biocompatibility of Dental Implant: Revised , Nagy Abdulsamee, Ahmed Elkhadem and Passant Nagi
A dental implant is a good example of the integrated framework of science and technology in multiple disciplines, including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering, among different dental materials and their effective applications. There are important features for dental implant systems, like all other dental materials and products, since the surface of dental implants is directly in contact with vital hard/soft tissue and is sub-ject to both chemical and mechanical bio-environments. Such appliances should include, at the very least, biological compatibility, mechanical compatibility and morphological compatibility with the important tissues surrounding it. Most of the dentists know well biological compatibility but overlook mechanical compatibility, and morphological compatibility. Therefore, this review throws a deliberate sight on these points.
205 Pyogenic Granuloma - A Simple Treatment Approach with Sclerotherapy , Shalini Subramanyam and Peeyush Shivhare
Pyogenic granuloma (PG) is a benign exophytic vascular tumor, which is actually a reactive inflammatory mass of blood vessels with few fibroblasts within the mucosa or skin, was first reported by Hullihen in 1844. Variety of treatment options such as surgical excision, laser treatment, electrodessication, chemical cautery, cryosurgery, intral-esional steroid injection etc. are available, but many a times, recurrence has also been reported.Sclerotherapy is defined as the “targeted elimination of small vessels, varicose veins and vascular anomalies by the injection of a “sclerosant”. It offers an alternative to conventional methods like surgery, lasers, radio frequency ablation and electrodesiccation procedure with success and less chance of recurrences.Herein, we present a case of 22 years old female with a clinical diagnosis of PG, treated with intralesional 0.2 ml of 3% sodium tetradecyl sulfate (STS). The lesion healed completely at the patient’s 3rd visit and recurrence was not reported till the patient was followed up for one year.

212 Human Immune Response to COVID-19 Infection and Potential Role of Chloroquine Family of Drugs: A Review , Sunita Singh, Chandrashekharaiah PS, Vishal Paul, Santosh Kodgire, Shivbachan Kushwaha, Debanjan Sanyal and Santanu Dasgupta
In December 2019, COVID-19 disease outbreak started from Wuhan, China. World is still, witnessing a massive morbidity and mortality due to the pandemic caused by novel coronavirus severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). This newly discovered virus enters inside and infect the body cells through the angiotensin-converting enzyme 2 (ACE2) receptor. The S1 protein of SARS-CoV-2 binds to the ACE2 receptor which results in endocytosis and transfer of virus into endosomes of body cells. Entry of SARS-CoV-2 results in activation of the innate immune responses first followed by the adaptive immune responses. The effective host immune responses are crucial to control and prevent the viral infections. However, the excessive production of pro-inflammatory cytokines and decrease in the number of T-lymphocytes are the major reasons associated with severity of COVID-19. Therefore, anti-inflammatory drugs such as Chloroquine (CQ) and hydroxychloroquine (HCQ) may play a crucial role to control and prevent the progression of disease by immunomodulation. The treatment responses of COVID-19 patients to these drugs have been found positive in some cases and clinical studies are underway for evaluating these drugs for the same. Moreover, regulatory bodies such as Food and Drug Administration (FDA) and European Medicines Agency (EMA) have recommended usage these drugs in emer-gency and chronic situation to treat critically ill COVID-19 patients under doctor’s supervision. The national task force (NTF) set up by Indian Council of Medical Research, has recommended high risk individuals to take HCQ for prophylaxis. This review summarizes human immune response and various aspects of CQ and HCQ with special reference to COVID-19.
213 Helicobacter pylori Treatment , Abdulaziz Radhi S ALjohni, Bassam A Aljohny, Sultan Saud Alahmad, Abdulaziz M Hakami, Omar Alfaroq and NA Al-Tayyar
H. pylori the Helicobacter genus, is found in over 80% of cases of gastric cancer in developed and emerging nations. H. pylori is gram-negative and is responsible for gastroduodenal diseases as the recognized major human bacterial pathogen. It will remain in the stomach for life until acquired and colonized. Acute and chronic gastritis, peptic ulcer disease, gastric adenocarcinoma and lymphoid tissue tumor combined with mucosa are found in a limited population of carriers (MALTA). In certain instances, H. The pylori infection is absolutely asymptomatic or has signs that are nearly imperceptible. H. pylori are different depending on the form of media, blunted/rounded ends in gastric biopsy specimens, but in fresh culture on agar medium they are rod-like and spiral shape when coccoid is on prolonged culture.Infection therapy depends on a mixture of antimicrobial agents and antisecretory agents, and the bactericidal activity of anti-microbial agents includes an elevation of gastric pH by antisecretory agents. Alternatively, although the mechanism of action is not yet apparent, to enhance eradication of H, phytomedicines and probiotics have been used H. pylori. The effect of antimicrobials and antisecretory agents is not only based on their pharmacological action, but also on their pharmacokinetic properties. Several anti-microbial agents have been used for H, including amoxicillin, clarithromycin, levofloxacin, metronidazole, tetracycline, rifabutin and compounds containing bismuth H. pylori

The prevalence of clinical manifestations is still unidentified, the range of COVID-19 manifestations on the oral cavity has been seen in various forms. The cur-rent case series aims to report a rare finding of bone and soft tissue defect in maxilla as a possible sequelae of C0VID-19 infection.
218 A Novel Reconstruction of a Large Mandibular Cystic Defect by Bone Graft Substitute , Radhika Shashank Tayshetye, Nitin Bhola, Anendd Jadhav and Chirag Patil
Odontogenic cysts are the most common lesions in the oral and maxillofacial region. The commonly chosen treatment approach for it is enucleation and extraction of the involved tooth, if required. To decrease infections and for spontaneous bone regeneration, various bone grafts are increasingly investigated for filling the defect. Autogenous bone graft being the gold standard has its various shortcomings which lead to the search for allogenous, xenografts and alloplasts. Surgical grade calcium sulfate is considered a con-venient, safe and readily available bone graft substitute with consistently successful results. This uniqueness of Calcium Sulphate has increased its purpose in the void filling. The purpose of this paper is to present a case of a large Dentigerous Cyst (D.C.) which was successfully managed by antibiotic impregnated Calcium Sulphate as a Bone Graft Substitutes in post cystectomy defect and exhibit its spontaneous bone regeneration radiographically

Periodontal disease is the most prevalent disease across the world. It is an inflammatory disease involving progres-sive and episodic loss of the periodontal attachment apparatus with tissue destruction consequentially arising out of host response against bacterial antigens as well as irritants leads to loss of alveolar bone and supporting the teeth. Chronic periodontitis causes various types of bony defects, among them intra-bony defect is most common. There are two primary treatment modalities for treat-ing periodontitis and associated changes, including non-surgical and surgical periodontal therapy.
222 Clinical Evaluation of Efficacy of 1.2% Atorvastatin Loaded in PRF with Collagen as a Barrier Membrane in Alveolar Ridge Preservation after Mandibular Molar Extraction , Kankipati Amrutha, Rupasree Gundala, YSHS Chakravarthy Reddy, Dalli Bharath Simha Reddy, Putta Sri Krishna Chaitanya and Patcha Harika
Extraction of teeth accounts for loss in height and width of the tooth dependent alveolar process, which results in a significant structural and dimensional changes leading to the atrophy of the residual ridge. Most of the resorption occurs during the first 3 months of healing, although dimensional changes can be observed up to 1 year after tooth extraction. Therefore, regenerative or other surgical intervention appear to arrest the bone resorptive process, to restore the alveolar process thus preserving the natu-ral contours and preparing the anatomical surroundings for the suggested prosthesis.To evaluate and compare the efficacy of 1.2% Atorvastatin loaded in PRF with collagen as a barrier membrane in alveolar ridge preservation versus controls after mandibular molar extraction, by measuring the following clinical parameters like relative coronal level of gingiva, mucogingival junction, crest of socket, socket depth, socket width at the most coronal level and to evaluate bone density changes radiographically by QDSR (Quantitative Digital Subtraction Radiography) technique in 1.2% Atorvas-tatin group and controls.

Each group was further divided into two subgroups based on the root canal sealer used for obturation; AH Plus resin sealer and Sure-Seal Root bioceramic sealer. For assessment of the push-out bond strength, roots were sectioned horizontally to obtain 2 mm-thick discs from the coronal, middle and apical thirds, then discs were subjected to a compressive load via the universal testing machine followed by assessment of the failure pattern using stereo-microscope.
225 MALDI (Matrix Assisted Laser Desorption Ionisation): Imaging Modality for Tumour Diagnosis , Akshara Lenin, Prajakta Suresh Kundekar, Kumar Sougata, K yeswanth Sunny and Gaurav
MALDI or Matrix Assisted Laser Desorption Ionisation has emerged as a powerful, versatile imaging modality that has since its advent created ripples in the scientific community. The major reason for its success is the ability of this system to criti-cally analyze, study the macromolecules and detect their presence in thousands of samples simultaneously. Moreover, because of its soft ionization techniques, it is now possible to study the biomolecules which would have previously decomposed due to inappropri-ate ionization skills. It is also the first of its kind to bring the world of mass spectrometry and the world of histology under the same banner creating a modality that is currently transforming the way we have understood the world of bioinformatics. Now it is possible to study a broad spectrum of analytes in unprecedented detail most of which until a few years ago had been completely unknown to the scientific communities.
226 The Advantages of Saliva Sampling Method for Diagnosis of COVID 19 , Amera K Alkaisi and Salma B Abdo
Several tests for many persons have to be conducted in order to control the pandemic and prevent the possibility of transmission of (Covid -19) to health care workers and other patients. The main aim of this study was to detect the importance of saliva sample for early diagnosis of Corona virus 2019 (COVID-19). Saliva sample considered as an alternative for diagnosis of COVID-19 as salivary gland found to express surface receptor angiotensin converting enzyme II, (ACE2) a receptor that plays a key role within the entry of SARS Corona Virus-2 (SARS-CoV-2) into the cell. The sample can be self-collected from the entrance of the oral cavity easily, in a way the risk of virus transmission to healthcare personnel can be minimized avoiding the use of protective equipment. There are several ways for collection of saliva, such as spitting out, directly from salivary duct gland and collection with sponge- like device. The analysis of Saliva can be used to detect oral cancer, dental caries, periodontal diseases, diabetes, breast cancer, and lung cancer. The saliva polymerase chain reaction (PCR) test demonstrated high sensitivity comparable performance to the current standard naso-pharyngeal and throat swabs. In addition, saliva could be used for monitoring viral clearance, as it contains the highest live COVID-19 viruses and viral load during the first week.

229 Challenging Issues in Development and Integration of Modern Kinematics with Components and Images Obtained from Different Sources in Biomechanical Applications , Yevsey Gutman, Nadejda Krasnorutskaya and Gary Gutman
In spite of the existing and successful development of CAD/CAM methods for mechanical applications, the ability to model the motion of biomechanical systems still presents many challenges. The reason for those challenges is in complexity of the nature of components to be used for the projects, specifically based on the origin of the parts: where are they coming from. Depending on the biomechanical application it could be as many as three different sources for the parts to be included in to the “assembled” system. They are: (1) “standard” parts which can be designed using the conventional CAD system, (2) parts which can be obtained only through the process of surface scanning; and (3) components which are the product of CT scanning with volumetric property. An Advanced method is discussed here which can deal in case of biomechanical systems to address the weaknesses of the Standard Ap-proach in use for purely mechanical systems.
230 A Comparative Evaluation of the Efficacy of Herbal Mouthrinse (P. granatum and S. persica) with Chlorhexidine Mouthrinse on Inhibition of Plaque and Gingivitis , Anamika and Amrinder Singh Tuli
In the past 40 years, Chlorhexidine has been extensively studied and used for plaque control in dentistry. It is a bisbigu-anide and is considered as a gold standard antiplaque agent due to its prolonged substantivity. It has a limited use period due to its known side effects such as extrinsic stains and alterations in taste sensation. On the other hand, mouthwashes made from the herbal and plant sources containing natural occurring active ingredients provide a gentle, harmless and a trustworthy option. P. granatum and S. persica are such plant products that are known to have antiplaque effects. Moreover, their use also overcomes the side effects caused by the chlorhexidine.
231 A New Microscope to Tiny Tumours - A Systematic Review , Kumar Sougata, Prerana G and and Gaurav
The authenticity and expertise of various imaging systems have been usually restricted as most of these imaging systems cannot visualize minute tumours. This is the reason certain cancers such as ovarian cancers and breast cancers are only diagnosed in their terminal stages. Moreover, despite landmark advances in varied areas of diagnostic imaging the detection and screening for most of these tumours remain poor. As the world is constantly being woven in the cocoon of technology it thereby be-comes imperative to develop and come up with better diagnostic modalities than the ones available to us. Also, with the global cancer burden constantly on the rise, various new imaging modalities come up as new waves in the field of radiology.Aim of the Study: To assess the significance of imaging systems in the diagnosis of small-sized tumours.
232 Role of Corticobasal Implants in the Rehabilitation of Dentoalveolar Trauma , Ashish Chakranarayan and Priya Jeyaraj
Management of dentoalveolar trauma often poses a unique challenge in terms of a need to replace both dental and bony hard tissues. In cases with loss of bone along with tooth the crestal implant-based management is often delayed due to insuf-ficient bone. Corticobasal implants offers a comprehensive management for such conditions. Three cases of dentoalveolar trauma were managed and rehabilitated successfully at our centre using cor-ticobasal implants. No adjunctive bone reconstructive or regenerative procedure, such as bone grafting or distraction were carried out to facilitate implant placement.
233 Salivary Proteomics and Transcriptomics: An Evidence-based Systematic Review , Shivangi Pandey, Kuntalika Sarkar, Kumar Sougata and Gaurav
Proteins are considered to be the building blocks of our bodies and they are known to harbor a vast array of informa-tion, the spectrum of which ranges from the knowledge of physical or pathological conditions to provide us with a pool of biomarkers. Saliva at the same time forms an indispensable part of the oral cavity and with recent researches, it is known to be a huge source of these proteins. As biochemical and molecular technologies are developing each day the gradual intersection of the above two men-tioned sources (saliva and proteins) becomes an inevitable pool of knowledge which if carefully studied could throw open future doors of non-invasive diagnostic procedures encompassing multitudes of systemic and metabolic diseases. In this literature review, we have tried and explained the two important biomarkers present in saliva namely proteomes and transcriptomes, and how these are eventually co-related and could serve us to understand the bigger picture of quick and efficient diagnosis.

235 “Trail” in Cancers - Time to Curb the Crab: A Meta-Analysis Research , Ayushi Bhargava and Gaurav
TRAIL (tumor necrosis factor related apoptosis inducing ligand) is the one of the recently developed method for curing cancer. The method demonstrates modified lipid nanoparticles which attaches to TRAIL and E selectin all of which coats the WBCs. The designed nature of modified leukocytes is cytotoxic and shows homology to TNF leading to targeted death of cancerous cells without harming normal healthy cells of one’s body. These modified leukocytes designed using body’s own defenses track down and induces apoptosis of absconding cancer cells. This approach shows large potential for patients with metastatic cancer as TRAIL coated leukocytes occur innate. Since current therapies have lot of disadvantages with it, which allows TRAIL therapy to be investi-gated at a large scale
236 COVID-19, An Eye Opening Pandemic - A Mini Review , Peeyush Shivhare, Shalini Subramanyam and Prapulla Sridhara Murthy
Corona virus disease (Covid-19) is an infectious disease of newly discovered Corona virus variant towards the end of the year 2019. It quickly infected thousands and millions of people all over world, spreading widely like a wildfire. By the end of January 2020, World Health organization declared the outbreak as global health emergency and later in March 2020, they announced COVID-19 as a global Pandemic. The uniqueness of Covid -19 was how little was known about the disease. Hence, it was a battle for many research-ers, scientists, doctors, dentists, governments and the masses to understand the ongoing Pandemic situation. Although predomi-nantly COVID-19 affects lungs, it did have manifestations on other parts of the human body. Here in this mini literature review, we tried to shed some light on basic aspects of COVID-19 along with oral manifestations, pathophysiology from the dental aspect along with recent advances in Vaccine and the ongoing clinical trials. We encourage active participation of Dentists in promoting the aware-ness and preventing the spread of covid -19 by understanding and equipping themselves with recent updates on this very disease.
237 Metagenomics: Rejuvenating Oral Medicine: Concepts Recultured- A Meta-Analysis Research , Shivangi Pandey, Shailaja Kushwaha, Pallab Roy and Gaurav
Metagenomics is the study of genetic material which has been directly taken from environmental samples. It is also known as environmental genomics, ecogenomics or community genomics. The initial molecular work in this field was done by Nor-man R. Pace and colleagues, they used PCR to explore the diversity of ribosomal RNA sequences. The knowledge that was gathered from these explorative studies led Pace to propose the idea of cloning DNA directly from environmental samples in the early 1985. Metagenomics as said can be a powerful tool to view the microbial world and its hidden diversity of microscopic life. Metagenom-ics offers immense potential to understand the entire world of living creatures around us. Since DNA sequencing shows a fall, when compared to metagenomics, which now allows microbial ecology to be investigated at a much larger scale and detail than before.

The aim of this study was to evaluate and compare 3 file systems; M-Pro, FlexMaster and RaCe in preparing moderately severe curved mesiobuccal canals of human mandibular molars regarding: transportation of the canal, the centering ability and change of radius of canal curvature, using cone-beam computed tomography (CBCT) scanning. A total of fifty-one mesiobuccal root canals of extracted human mandibular first and second molars with the angle of curvature ranging 20-35 ͦ (according to Schneider) were collected and divided into three equal groups. After access cavi-ties preparation and working length determination, distal roots with the respective part of the crowns of all samples were sectioned at the furcation level and discarded. Samples were mounted in acrylic resin molds and then CBCT scanning was done pre and post instrumentation using the same scanning parameters. Root canal preparation was done according to the manufacturers' instructions of each NiTi system. The pre and post-images were superimposed using a fusion module of OnDemand 3D App software to measure the dentin thickness at root canal levels (2, 3, 5 and 8 mm from the tooth apex). Canal transportation and centering ability were re-corded according to formula introduced by Gambill., et al. while the change in the radius of canal curvature was recorded following Estrela., et al. Data was tabulated and statistically analyzed.
239 Pattern of Mandibular Third Molar Impaction in North-Central Nigeria: Panoramic Radiographic Assessment , Seidu Adebayo Bello and Nathan Ukuoghene Ikimi
The third molar is the most common tooth in the mouth that fails to erupt partially or completely into its functional position and this could be because of an impediment on the eruption path. Management of impacted third molar is usually by a surgical procedure extraction and successful treatment is enhanced with the aid of a radiograph which is either the periapical x-ray or the panoramic radiograph. This study reports on a large population of patients, using the panoramic radiograph to evaluate and compare with the periapical radiograph the various pattern of the impacted mandibular third molar presented in north central Nigeria.A retrospective examination of digital panoramic radiographs obtained from patients who had surgical extractions of impacted mandibular molars between March 2016 to April 2020. The data obtained were analysed using the Statistical Packages for the Social Sciences (SPSS) version 20. Chi-square test was done to determine statistical significance which was set as P < 0.05.There were 366 (55.8%) male and 289 (44.1%) females, with an age range of 16 to 70years and a mean age of 34 ± 12.5 years. Impaction was found on one side of the mandible in 30.3% and on both sides of the mandible in 69.5% of the patients and the most common type of impaction according to Winter’s classification was mesioangular impaction and found more common among males in this study at 43.4%.Our results here gave better clarity with the use of the panoramic radiographs and therefore strongly recommends the orthopan-tomogram (OPG) before any mandibular 3rd molar extraction is done.
240 Labial Type Dens in Dente: A Rare Case Report , Manisha D Yadav, Bhakti Patil Soman and Deepa Das
Dens Invaginatus, also known as dens in dente a rare developmental anomaly affecting human dentition. It arises as a result of invagination into the surface of tooth crown or root before calcification has occurred. Most commonly affected teeth are permanent maxillary lateral incisors and is usually seen on the palatal aspect. In the present case report it was, rare to be seen on the labial as-pect of maxillary central incisor. This anomaly may increase the risk of pulp disease and can potentially complicate treatment due to its aberrant anatomy thus, posing a diagnostic challenge. Radiography plays a vital role in diagnosing such developmental anomaly. Compared to conventional radiograph Cone Beam Computed Tomography (CBCT) plays an invaluable role in the diagnosis of the ex-tent dens invaginatus and in appropriate treatment planning. This case report highlights the role of CBCT in the diagnosis of various types of dens in dente.
241 Unusual Clinical Presentation of Oral Leukoplakia: Case Report and Review of Literature , Lavanya Pasalkar, Shrutika Sonawane, Vikram Khare, Pallavi Channe
Oral cancer is the most commonly seen malignancy in Indian males and leukoplakia is the commonest of all precancerous lesions which can transfer into oral carcinoma. The estimated global prevalence of oral leukoplakia is 2.60% with 0.13 to 34% malignant transformation rate. It has been proved that clinical type, grade of dysplasia and age are associated risk factors with malignant transformation. A 38 yrs male patient found to have a tiny solitary well defined white plaque like lesion on buccal mu-cosa hardly 2 mm x 3 mm which was unnoticed by the patient till then. Surface of the lesion was raised, rough and wrinkled. It was non-scrapable. Patient had tobacco and gutka chewing habit with cigarette smoking since 5 years. Though the size of lesion was too small considering all the factors provisional diagnosis of homogeneous leukoplakia was given. An immediate excisional biopsy was performed. Histopathological examination revealed oral leukoplakia with moderate dysplasia. Dysplastic changes could have been a major risk factor for malignant transformation. Early diagnosis and excision of lesion ensured good prognosis.

246 Evaluation and Compare Effectiveness and Durability of ICON Resin Infiltration and Acidulated Phosphorus Fluoride in Treatment of Post-Orthodontic White Spot Lesions , Mohamed Said Ibrahim, HalaMunir2, Fady Hussein and Dalia El Boghdady
Randomized clinical trial was conducted to evaluate of the effectiveness and durability of Icon resin infiltration compared to acidulated phosphorus fluoride in management of white spot lesions. Eighteen patients with an age range of 12 - 25 years which included both males and females were enrolled in this study. The scoring criteria according to the lightness scale were graded from 0 to 100. Patient satisfaction score was recorded using a visual analogue scale from 0 to 100 according to patient's own evaluation for each quadrant before, after intervention and after 3 months follow up. A significant improvement of WSL esthetics was found im-mediately after Icon resin application by 18.2% and 18.8% in both upper and lower arches respectively. However, after three months follow up it was significantly reduced to 15% in the upper and 17.2% in the lower arches. A slight improvement in esthetics of white spot lesions was found immediately after APF application by 7.2% in both upper and lower arches while, after three months follow up period it significantly improved from 7.2% to 10% Patient satisfaction scores revealed that before application, there was dissatisfac-tion among the patients of the perception of their teeth. However, greater satisfaction scores were found immediately after Icon resin and APF application and after 3 months follow up. This results suggest that Both Icon resin and acidulated phosphorus fluoride gel improved esthetics of white spot lesions

Aims: To evaluate the change in the attitude and expectations of the undergraduate dental students when introduced to a specially developed Geriatric Education Program (GEP) ii. To qualitatively analyse the students’ perceptions and experience about the intro-duced GEP in their curriculum.
257 The Impact of COVID-19 on the Environment. Short Review , Nagy Abdulsamee, Ahmed Elkhadem and Passant Nagi
The COVID-19 disease has recently spread as a global pandemic, posing serious threats to mankind. The World Health Organiza-tion (WHO) has issued guidelines to assist countries in reducing the spread of the virus to the general public, including the use of masks, hand hygiene, social distancing, and the shutdown of all kinds of public transportation. These circumstances resulted in a significant drop in global economic activity, but there were also indirect environmental benefits such as improved global air quality and reduced water pollution. Because there are no clinically proven drugs or vaccines for COVID-19, face masks are currently part of a comprehensive package of prevention and control measures that can limit its spread. Face masks are typically made of non-renewable petroleum-based poly-mers that are non-biodegradable, dangerous to the environment and cause health problems. This review demonstrates the extensive use of the face mask and how it affects human health and the marine ecosystem positively as well as negatively. It has become a great challenge for the government sectors to impose strict regulations for the proper disposal of the masks as medical waste by the public to minimize their negative effects. Neglecting the seriousness of this issue may lead to the release of large tonnes of micro-plastics to the landfill as well as to the marine environment where mostly end-up and thereby affecting their fauna and flora population vastly
258 Gorlin-Goltz Syndrome: Literature Review and Report of Two Clinical Cases , Juliane Maria Iagnes Prestes and João Luiz Carlini
The Gorlin-Goltz Syndrome, also known as Basal Cell Nevus Syndrome, is characterized by the triad of multiple basal cell carcino-mas, keratocystic odontogenic tumors, and skeletal abnormalities. However, due to its variable expressiveness, other manifestations may occur, making diagnosis difficult. In this article, we aim to recall the signs and symptoms that can be identified in the bearer of this syndrome by reviewing the literature, alerting the health professional, and discussing their diagnostic process, illustrating it with two clinical cases from the Federal University of Paraná (UFPR). It was also intended to indicate its adequate treatment, since the management of this condition requires the monitoring of a multidisciplinary team in the long term, due to the involvement of multiple systems, the high rate of recurrence of the lesions, and the late appearance of carcinomas.
259 Accuracy of 3DPrinted Windowed Bracket-Positioning Guide Versus Thermoformed Transfer Tray for Orthodontic Indirect Bonding: A Randomized Clinical Trial , Amany El-tantawy, Amr Abouelezz, Amr Ragab El-Beialy and Mai Hamdi Aboul Fotouh
To compare the digital 3d printed window transfer tray and the conventional thermoformed tray regarding the accuracy of transferring the attachments.A randomized clinical trial was performed the two different bonding techniques, 144 attachments were recruited in this study. In the control group, the orthodontic attachments were bonded to working models and scanned with an intraoral scanner to make STL file of the working model. The transfer tray was then fabricated in order to transfer the orthodontic attachments in to the patient’s mouth. While in the intervention group, the teeth were scanned with the same intraoral scanner to produce the digital model on which the virtual attachments are placed using the OrthoAnalyzer software. The tray was designed and printed with win-dows opened gingivally. The attachments were fitted into their positions through the windows of the tray. Then intraoral scanning for both groups was done to obtain STL models after bonding. Superimposition of the pre and post STL models was done using 3Shape OrthoAnalyzer software to measure the angular deviations (tip, torque and rotation).
260 The Effect of Desensitizing Agents on Open Dentine Tubules- An , Baruch Nurit and Zilberman Uri
Dentin sensitivity can be treated by blocking the exposed dentinal tubules or by interrupting neural response for pain stimuli.To analyze in vitro the plugging effect of open dentin tubules by three desensitizing tooth pastes and a desensitizing agent.V shaped cavities were made on the buccal surface of 18 extracted premolars. On each group of 3 premolars each, the exposed dentine was brushed with water (control), 3 desensitizing tooth pastes (Oral B-gum and enamel repair, Sensodyne-dual care, Colgate-sensitive pro-relief ), a parodont expert toothpaste (Meridol) and a desensitizing agent (Riva Star desensitizing agent) twice a day for 30 seconds, for 10 days. Two days after the last brushing, the dentin surface was analyzed with SEM to observe the effect of the agents on dentine tubules. Using the Energy Dispersive X-ray Spectrometer (EDS) program the ion content of the dentine surface (%WC) was examined, in order to analyze the effect of toothpaste ingredients on the dentine.Results: Tooth-brushing with water, Meridol and Sensodyne dual-care left the dentine tubules open with no plugging. Colgate-sen-sitive pro-relief toothpaste caused plugging of 40% of the tubules, while Oral B gum and enamel repair applied a plugging material on 100% of the tubules. Riva Star covered the dentin with amorphic material. The ion content of the dentin surface after using Oral B showed apposition of zinc, tin and titanium, Colgate showed apposition of zinc and Riva Star showed apposition of fluorine, alumi-num, silver, iodine and tellurium on the dentin.

265 Van Der Woude Syndrome: Report of a Case , Krutarth Kshirsagar, Anendd Jadhav, Rajanikanth Kambala and Nitin Bhola
Van der Woude Syndrome (VWS) is a genetic disorder caused by a dominant mutant gene on an autosome which is associated with lower lip pits and clefts of the lip and/or cleft palate. Considerable heterogeneity regarding expression of the disorder constitutes a rare developmental malformation as congenital pits of the lower lip. Commonly associated characteristic features with lip pits are submucosal palatal clefts, velopharyngeal insufficiency and genitourinary or cardiovascular anomalies. The association of congenital pits with clefts is observed in about 50% of cases. They are usually located on either side of the midline of the vermilion portion of the lower lip, symmetrically and bilaterally. They may also present as unilaterally, medially or bilaterally asymmetrical structures. Surgical excision is the best-choice of treatment for lip pits. As the presence of salivary tissue in any residual tract increases the pos-sibility of cyst formation, excision of lip pits is crucial in ensuring proper removal of the entire tract. In the present case scenario fistula repair was done using tongue flap and surgical excision of lip pits was performed using wedge incision. The purpose of the current case report is acquiring adequate knowledge about proper evaluation and treatment along with genetic counselling which will provide a proper guide for management of such cases
266 Evaluation and Compare Chairside Time and Accuracy of Indirect Bonding of Orthodontic Attachments Using Double Versus Single Transfer Tray (Split Mouth Design): A Randomized Controlled Trial , Mohamed Essam Mohamed, Fatma Abdou Abd El Sayed, Hoda Mohamed Abdul Aziz and Mai Hamdy Aboul Fotouh
Comparing the difference between two types of indirect bonding trays (single sheet versus double sheets) regarding chairside time and accuracy of transferring orthodontic attachments in all 3 planes of space using 3D scanning and superimposition.A randomized controlled trial (split mouth design) compared between the single versus double transfer trays tech-niques was performed, 6 patients with fully erupted full set of permanent teeth were recruited in this study. 84 attachments were bonded to the maxillary teeth from central to second molar for both groups. After placement of the attachments on the working model using water soluble glue regarding the vertical and horizontal reference lines, the model was sprayed with titanium dioxide powder then scanned with intraoral scanner and preoperative STL file was saved. The single and double transfer trays were fabricated, one on each half of the working model then the trays were divided, trimmed and prepared for bonding procedure. The attachments were transferred to the patient’s dentition using the two techniques, then the patient’s dentition with attachments were scanned with the same intraoral scanner and post- transfer STL file was saved. The chairside time for each group was measured using stopwatch. By using the Geomagic qualify version 12, the two STL files were superimposed and the deviations were detected for 7 values, 4 linear measurements (total linear, mesio-distal, occluso-gingival and bucco-lingual) and 3 angular measurements (tip, torque and rotation). The attachments failure rates were recorded immediately. A visual analog scale was given to each subject to measure their satisfac-tion towards the both used indirect bonding techniques.

276 Use of Hawley’s Appliance to Prevent Dead Space Formation After Minor Oral Surgery: A Novel Technique , Anmol Agarwal, Gaurav Mittal, Payal Agarwal, Santosh Kumhar  and Neel Gupta
Dead space, or a space remaining in the tissues due to improper closure of surgical wounds, permitting the accumulation of blood or serum underneath the tissues. Although seen commonly after general surgical procedures but is also commonly noticed after minor or major oral and maxillofacial surgical procedures. For example, enucleation of a cyst, excision of the exophytic growths etc. All such procedures requires elevation of a full thickness mucoperiosteal flap leaving behind a large portion of unsupported tissue due to excision of lesion. Such flaps when sutured back tend to develop dead space beneath which in turn can get infected and lead to secondary morbidity

296 The Association of Trace Elements and Vitamins with Lichen Planus: Review Article , Maryam Baghizadeh Fini
Lichen planus is a continual mucocutaneous inflammatory disorder of multifactor nature with numerous clinical symptoms. Nu-merous researchers attribute a key role in disease development to disruptions in the immune system. Appropriate doses of micronu-trients are essential for the immune system to perform effectively. Micronutrient deficiency suppresses immunity by influencing the innate immune system, responses to T-cell mediated and adaptive antibody, resulting in disruption of the balanced host response. Since these trace elements and vitamins have an important role in the immune system and oral lichen planus has a significant rela-tionship with the disturbances in the immune system, the importance of these elements should be considered for each patient. Just several articles examined the hematological anomalies and nutritional imbalances in OLP patients. In this study, all required informa-tion about trace elements and vitamins in OLP patients is obtained.

306 Prosthetic Rehabilitation of Siebert’s Class II Case and Pier Abutments - Case Report , Swati Pustake, Kanchan Bagul, Sachin Chaware, and Preetha Negi
Replacement of teeth with periodontally compromised abutment is a challenge. A tough choice of aesthetics over function is often made by the operator for the satisfaction of the patient. The modified concepts of fixed partial dentures allow one to choose longevity of the prosthesis by not compromising on the aesthetic factors. Ridge defect often leads to a convenient treatment option of removable partial dentures which will not be preferred by the patient. Andrews bridge a fixed removable type of prosthesis is perfect solution for this situation. In long span multiple missing cases Nonrigid connectors have been recommended to reduce the forces as they provide a stress-breaking effect. In this case report, there are two opportunities that allow us to incorporate the modified fixed partial denture technique. Andrews bridge in the lower anterior segment to mask the ridge loss and the posterior long span FPD with a tenon mortise attachment. These two attachments used in this case not only prolongs the life of already compromised anterior teeth but also allows the posterior abutment to remain healthy throughout in long span fixed partial dentures

314 Coping with the Corona Crisis-Mental Status and Beyond , Aditya Jayan and Gaurav
“Life” as Atharva Veda describes is not merely a sequence of events from birth to death, but also a culmination of various emotions, feelings and frames of mind where it ushers from the cuddling arms of the parents to the burning arms to the funeral pyre! “Lockdown” on the other hand if interpreted aptly is not an act of being imprisoned but a longer period of discipline and an act towards the Nation. Its a test of mindset wherein we are getting to serve our nation without actually doing anything being back at home! Its a persistence of the mindset that we will not go back to normal, normal never was! Our pre-corona existence was not normal other than we normalized greed, inequality, exhaustion, depletion, extraction, disconnection, confusion, rage, hoarding, hate and luck.

318 Non-Surgical Management of Unusually Large Chronic Recurrent Periapical Abscess and an Insight on Periapical Radiolucencies , Swati Gupta, Ramakant Gupta and Manju Gupta
Recurrent inflammatory periapical lesions are commonly encountered oral pathologies. The usual cause of these periapical lesions is endodontic in nature and can be easily treated by endodontic treatment. They exhibit wide biologic behaviors and their presentation as recurrent pus discharging ulcers can lead to patient’s apprehension and even be cause for clinician’s anxiety. This is because many non-endodontic causes may also lead to periapical lesions. A thorough knowledge about them therefore, is crucial for clinicians not only to properly diagnose and manage such cases, but is also important to safeguard themselves from patient’s evil intentions of making easy money by claiming refund. The present case is one such example where unusually large chronic recurrent periapical abscess was managed with non- surgical endodontic treatment. With this case report, authors intend to discuss the different periapical radiolucencies and explain scientific guidelines for their adequate diagnosis and management.

Introduction: A high prevalence of diabetes mellitus and dental caries in Saudi Arabian population is overwhelmingly reported. The aim of the study was to assess the following: 1) clinical findings of PD, BOP, and amount of keratinized tissue present around dental implant and 2) PICF levels of IL-1α, IL-1β, IL-6, and IL-8 in diabetic and non-diabetic partially edentulous Saudi Arabian subjects. Materials and Methods: Total of 32 partially edentulous subjects, 16 diabetic and 16 non-diabetic, were included in the study. PICF samples were taken from peri-implant sulcus using paper point and PCR essays for IL-1α, IL-1β, IL-6, and IL-8 was performed. Clinical parameters of peri-implant PD, BOP and amount of keratinized tissue were recorded. Conclusion: PD, BOP and PICF IL-6 levels were found to be significantly higher in Saudi Arabian diabetic subjects compared to Saudi non-diabetic subjects. Also, a positive relation found between deep PD and four inflammatory markers which are IL-1α, IL-1β, IL-6 and IL-8. Results: Diabetic subjects had more significant BOP than non-diabetic counterparts (p-<0.001). No significant difference was found between diabetic and non-diabetic patients in the amount of keratinized tissue (P < 0.765). A significant high level of IL-6 in diabetic subjects when compared to healthy subjects (P < 0.033). No significant difference between diabetic and non-diabetic subjects in the serum level of IL-1α (P < 0.121), IL-1β (P < 0.171) and IL-8 (P < 0.223). A positive correlation between increased serum level of IL-1α, IL-1β, IL-6 and IL-8 with increased PD was determined.

328 Utility of Sodium Tetradecyl Sulphate for the Management of Oral Venous Malformation , Krishna Kishor, Shiv Kishor, Heera, Hiralal Ash, Kumar Arunesh and Sudarsan Sen
Venous malformation are one of the most common lesions of oral cavity. The lesion may be congenital malformation in neonates or arteriovenous malformation in adults. Various surgical and medical managements are possible for vascular lesions which includes surgical excision, laser therapy, cryotherapy, selective embolization, intralesional sclerosing agents, beta blocker and steroid therapy. In this current study we assessed the efficacy of intra lesioned injection of sclerosing agent i.e. 3% sodium tetra decyl sulphate in oral lesions of venous malformation. Sclerotherapy with 3% sodium tetra decyl sulphate is an effective agent in treating benign oral lesion of vascular malformation and provides alternatives to surgical method.
329 Synergistic Effects of Cordycepin and Genistein on Preosteoblast MC3T3-E1 Cells with Endoplasmic Reticulum Stress , Jiaxuan Lu, Xin Luo and Xiting Li
Endoplasmic reticulum (ER) stress activation disturbs bone homeostasis and plays an important role in osteolytic bone diseases development. Cordycepin (3'-deoxyadenosine), a natural structural analog of adenosine, possess multiple pharmacological activities and exerts osteoprotective effect. Genistein can be used as protectors or synergists of adenosine drugs. The aim of the present study was to investigate whether the combination of cordycepin (Cor) and genistein (Gen) regulates proliferation, migration and differentiation of preosteoblast MC3T3-E1 cells in a tunicamycin (TM)-induced acute ER stress model. Cell viability were assessed using cell counting kit-8 (CCK-8) assay and osteoblast migration were evaluated by transwell chamber assay. The differentiation was assessed by alkaline phosphatase (ALP) staining assay. qRT-PCR assay was performed to confirm the establishment of ER stress model and to measure the mRNA level of key molecules involved in osteogenic differentiation. Exposure to the combination of 10μM cordycepin and 10μM genistein had no cytotoxicity in MC3T3-E1 cells, but increased the number of proliferative cells after pretreatment with 2 μg/ml TM. Analogously, ER stress-induced suppression on MC3T3-E1 cells migration was restored to control levels by the administration of cordycepin and genistein combination. Cordycepin and genistein combination significantly up-regulated ALP activity of MC3T3-E1 cells in TM-induced ER stress model. The qRT-PCR data demonstrated that the combined treatment effectively accelerated osteogenic differentiation by enhancing the mRNA level of differentiation markers including collagen type I, ALP, BSP and OPN. These results reveal that the co-administration of cordycepin and genistein exerts synergistic osteoprotective effects and has the potential to serve as a host risk reduction strategy for osteolytic bone diseases associated with ER stress activation.
330 Studying the Correlation between CBCT Linear Measurement and Actual Measurement during Surgery in Implant Candidates , Mehrdad Panjnoush, Yadollah Shayesteh, Elham Romoozi and Maryam Johari
Background: One of the main uses of CBCT is the design of implant therapies, and linear calculations in these therapies are important in quantifying bone (height and width). However, previous researches have all been conducted on dry skulls and no research has been performed in patients' clinical conditions. Aim of the Study: The aim of this research was to determine the correlation between CBCT linear measurements and actual measurements during surgery in patients undergoing implant surgery. Materials and Methods: In diagnostic research, 54 patients were selected for implant treatment in the premolars and the distance of the mental foramen to the apex of the ridge was measured using a caliper during surgery. The same calculations were repeated in CBCT images with Romex is software by two observers at two 2-week intervals. The difference in bone height calculations in CBCT images and actual measurements during surgery were analyzed by repeated values and ANOVA. Results: The difference in absolute value of bone height in CBCT images (second observer) and its actual values was 0.811 ± 0.54, 0.894 ± 0.67 between the first observer and its actual values,0.871 ± 0.63 between the first observer in the next 2 weeks later and the actual values,0.804 ± 0.57 between second observer in 2 weeks later and its actual values. The mean difference of bone height observations by 2 observers in 2 weeks from its actual values was equal to 0.0 ± 828.89 mm. No significant differences were observed between the absolute magnitude values of bone height measurements in CBCT images and their actual values at the time of surgery after exposure. Conclusion: Given the limited bone height difference in CBCT images from its actual values, this imaging modality appears to be a useful and accurate tool for estimating bone height in implant surgery in clinical settings.
331 Intraoperative Anatomical Surface Marking and Cone Beam Computerized Tomography for Assessment of the Hamulus in Palatoplasty by Younger Cleft Surgeons , Bergonzani M, Uy V, Zeinalddin M and Lotha B
Understanding the surface anatomy markers for the hamulus in palate surgery is often a useful pointer to the position of the hook of hamulus during cleft palate surgery. This innovative idea is of particular use in Veau 1 and 2 where only medial incisions are used. Younger cleft surgeons feel more comfortable when they are able to clearly see palate structures during careful dissection. Using the intraoperative method of marking out the position of the hamulus makes the whole process of identifying the hook of hamulus a lot simpler. Drawing a vertical line from the mid tuberosity which intersects a horizontal from the level of the posterior spine, the hamulus which lies a few mm below and medial to the intersection, can easily be found. We divide each region into clockwise zones 1, 2, 3, 4 and found the position to be consistent in zone 4, slightly medial and below the intersection of the two lines. This finding was also noted on cone beam CT images of adult and pediatric palates.

336 Legal Validity of Criminal Identification from the Comparative Analysis of Bitemarks , Joana Mancellos, Maria Inês Guimarães and Joaquim Gonçalves
Human bitemarks are normally associated with violent crimes, and when recorded, they can be the basis for the constitution of forensic evidence in a legal context. The recording and the comparative analysis of these marks, allied with data on the suspects, enable the elaboration of forensic reports that lead to the exclusion or non- exclusion of suspects, and they also contribute to the unfolding of a criminal proceeding in which the court is responsible for issuing a sentence to a defendant. The legal validity of the comparative analysis of bitemarks in human identification is a widely discussed topic in the scientific community. The numerous publications on this subject reveal different opinions regarding its contribution in crime situations and whether or not it is legally valid. The objective of this literature review is to determine the legal significance of bitemarks in the identification of criminals, considering the methods used to study bitemarks and the reliability of their results.

342 A Case of Sinonasal Lymphoepithelial Carcinoma Presenting as a Palatal Swelling , Nikolaos Kolomvos, Dionysios Kyrmizakis, Evangelia Piperi and Evanthia Chrysomali 
Lymphoepithelial carcinoma is a rare type of undifferentiated carcinoma, characterized by atypical epithelial cells surrounded by a reactive lymphoplasmacytic infiltrate. We report a case of sinonasal lymphoepithelial carcinoma arising in the left maxillary sinus in an 80-year-old Caucasian male patient. The lesion had invaded the adjacent lateral wall of the nasal cavity appearing on the palate as a painful swelling. There was no evidence of tumor involvement from the nasopharynx and larynx assessment and no swollen cervical lymph nodes were noticed on the head and neck imaging examination. An incisional biopsy from the oral cavity, as well as an endoscopic biopsy of the neighboring nasal mass were performed. The histopathological and immunohistochemical analysis of both specimens showed identical features and a common diagnosis of sinonasal lymphoepithelial carcinoma was rendered. In conclusion, oral swellings located on the palate may be associated with maxillary sinus malignancies. Thus, the clinician should include in the differential diagnosis not only primary oral carcinomas, but also malignant neoplasms arising from neighboring anatomic sites.
343 Role of Human Papilloma Virus (HPV) in Potentially Malignant and Malignant Lesions of Head and Neck , Paramita Ingle, Basavaraj Bhagawati and Meenal Jethlia
The sixth most common cancer diagnosed worldwide are head and neck cancer (HNC). In 2008, 633,000 new cases were diagnosed out of which 355,000 cases resulted in mortality. Early detection of precancerous lesions remains a challenge to clinicians. In 1983, evidence of Human Papilloma Virus (HPV) infection was identified in a subset of oropharyngeal carcinomas (OPC). Thus, confirming HPV as a causative agent in HNC. HPV is now recognized as an important risk factor for the development of oropharyngeal cancers, and results of previous studies have demonstrated epidemiological and molecular evidence of the presence of the HPV genome in pre-malignant oral lesions in SCC tissues, especially of the subtypes of HPV-16 and -18. There is close to no evidence linking HPV to carcinoma. However, this review focuses on the role of HPV in oral oncology and to comment on the HPV DNA reported frequencies potentially malignant oral lesions

346 Treatments for Paresthesias after Orthognathic Surgery: Literature Review , José Victor Marconato, Luis Eduardo Genaro and Paloma Fernandes
Orthognathic surgery is a procedure of choice for the treatment of skeletal deformities; however, it is common to observe a change in sensitivity called paresthesia, in cases where the nerves are injured. For the patient's sensitivity to return, it is necessary to perform treatments such as the use of low-power laser, acupuncture and drug treatment. This work sought to identify these treatments and describe them, in order to guide the clinical management of dental surgeons.
347 Comparing the Anxiety Level between Myofascial Pain Dysfunction Syndrome Patients and Others , Sara Pourshahidi, Hooman Ebrahimi and Zahra Pourabdollah
Myofascial pain dysfunction syndrome (MPDS) is the most common temporomandibular disorder and a psychophysiologic disease that primarily involves the muscles of mastication and can cause pain, mouth opening limitation, mandibular deviation during mouth opening and closing and tenderness of one or more masticatory muscles or tendons. Among various ideas about the etiologic factors of MPDS, two main reasons are occlusal disorders and mental health problem. More researches recently, focus on mental health problem as the main and initial factor of MPDS. Anxiety is one of the most fundamental psychological problem that exists in almost all societies, it increases muscle’s tonisity and thus leads to pain. Considering the high prevalence of anxiety in patients suffering from this syndrome, this study is to investigate anxiety intensity in these patients and compare that with two control groups. The first control group were 30 patients who referred to dental school because of any problems except MPDS, and the second one included 30 Shiraz citizens. All three groups were informed about the procedure of the study and then completed Spielberger Anxiety Intensity Questionnaire, that had been validated before. Then a psychologist checked and graded the questionnaires. Using spss v.15 we analyzed the data with ANCOVA and Chi-Square tests. This study demonstrated that the MPDS patients had more anxiety than the common people of the society. The significant point in our study was the comparison of anxiety level in MPDS patients with the other patients that referred to dental school with a reason other than MPDS which revealed no significant statistically difference. According to this result, we can say that the high anxiety level in MPDS patients may be not related to the disease and can be due to the situation they share with others who refer to dental school, so the anxiety may be the result of their disease and not the cause.

350 Contracted Endodontic Cavity in a Severely Calcified Anterior Tooth Using Guided Endodontics Technique: Case Report , Alessandra Rosa de Sá, José Flávio Gabrich Giovannini, Henrique Trindade de Magalhães, Victor Couto Figueiredo, Tiago Braga and Rodrigo Rodrigues Amaral
Pulp canal obliteration (PCO) is characterized by the deposition of calcified tissue within the root canal space, which may partially or totally involve the canal. The endodontic treatment of calcified teeth is considered a challenging task depending on the severity of pulp obliteration. Recently, guided endodontics has become an alternative approach for those cases. This case report describes the use of guided endodontic access for the maxillary left lateral incisor of a 73-year-old male patient that required restorative treatment. The tooth had an extensive coronary fracture and demanded endodontic treatment for prosthetic purposes. Periapical radiography showed that pulp obliteration was severe at the cervical and middle thirds of the root. A cone beam computed tomography (CBCT) was requested in order to assess the level of obliteration. A three-dimensional (3D) template was planned with the CBCT's images along with intraoral scanning. A prototyped guide for guided endodontic access was performed, and the dental procedures were concluded safely. Guided endodontic access was paramount to overcome the pulp obliteration and ensured the endodontic treatment, and prosthetic rehabilitation could be performed.

358 Advanced Diagnostic Aids in Detection of Potentially Premalignant Oral Epithelial Lesions - A Review   , Jayanta Saikia, Balaji Pachipulusu, Poornima Govindaraju and Bhagyashree M Nair  
Oral cancer is one of the most mutilating disease afflicting mankind. Precancerous lesions, conditions and early stage oral cancer cannot be adequately identified by visual inspection alone and may be easily overlooked and neglected. Differentiation between early stage cancer, precancerous lesions and benign lesions is often difficult because of the similar appearance of the lesions. Surgical biopsy is a gold standard for diagnosis, but this needs professional services, which are impractical at times. Alternative screening methods which are non-invasive, easily performed and highly accurate are the norms for any test to accept as an alternative for histopathology

366 Attachments in Cast Partial Denture: A Case Report , Swapnita Vaity, Omkar Shetty, Gaurang Mistry and Manali Mehta
Retention of prosthesis is one of the key factors in the success of the prosthesis. Apart from retention, one of the major concerns in removable partial dentures has been stress transfer on the remaining tissue; particularly in distal extension cases. The use of attachment gained momentum in around late 1950s after considerable efforts by Steiger and Boilet. The need for extra retention and improved esthetics, lead to the development of intra-coronal and extra-coronal attachments. Attachment is a mechanical device for fixation, retention, and stabilization of prosthesis. The criteria that help in the selection of the attachments are location, function, retention, space and cost factors. The article presents a case report on attachment in cast partial denture.
367 Transfloral Acupuncture - A New Combination of Ear Acupuncture and Floral Essences to Improve the Energy of Patients , Andreas Wirz-Ridolfi
In any patient the extension of the actual electromagnetic field is decisive for his state of health as well as for the effectiveness of any therapeutic measure. With the innovative method of Transfloral Acupuncture it is possible to improve the energetic level of patients considerably within seconds. Most foci (which are obstacles for diagnosis and treatment) are dental foci. Teeth, even if they don't yet need treatment by a dentist, can present a focus causing a considerable loss of energy for the patient. This loss of energy reduces his capability to react to treatment as well as his immune system. According to the research of Prof. Frank Bahr and Dr. Heike-Dorit Schmid every tooth is in resonance to a flower essence, (Bach, Californian flower essences or Australian Bush flowers). By means of the Vascular Autonomous Signal (VAS) and the Bahr detector (a combination of a 3-Volt hammer and a black and white hammer) all teeth are controlled and the corresponding flower essence is chosen. A drop of the floral essence is given orally and another drop is placed on the ear lobe of the patient at the place of the tooth found to be a focus. Now a permanent needle is inserted through the floral essence into the ear lobe

372 Rehabilitation of Patient with Immediate Cast Partial Denture Using Patient’s Natural Maxillary Anterior Teeth , Priyanka Tiwari, Rajesh Sethuraman and JR Patel
In dental practice immediate denture is commonly used before extracting all the remaining teeth. There are many advantages of using this denture such as esthetics, speech, occlusion, maintaining the facial height, muscle tone and tongue size. Maxillary anterior teeth as patient’s natural teeth are used due to improving the self-esteem, esthetics, smile and confidence of a patient. Also as natural teeth retain their hue and strength for sufficient period of time. Removable partial denture can be used but Cast partial denture is a better option as it provides better fit and hygiene and it is an alternative to the patient who are not willing to get fixed prosthesis done or in whom FDP is not indicated. Hence Immediate cast partial denture is the choice of treatment in such cases. In this case patient’s natural maxillary teeth is used to form immediate cast partial denture, together with replacement of missing teeth in maxillary and mandibular arches.

382 Binder’s Syndrome: The Need of an Ortho-Surgical Approach , Priti Shukla, Amit Nagar and Rachit Thakral
Despite the frequent presence of all characteristic orofacial features and profound dental malocclusions there is very little to be found in the literature of maxillofacial surgeons to diagnose a case of Binder syndrome or also known as maxillo-nasal dysplasia or maxillo-nasal dysostosis. Nordenram., et al. recommended to delay any definitive orthodontic treatment in individuals with this syndrome up to the time when growth has ceased. For severe cases they also advise for grafting in the nasal area along with Le-Fort I and II osteotomy. Thus, in such cases the orthodontic treatment should go hand in hand with the surgical team hence opting for an ortho-surgical approach. The aim of the orthodontist in the post-surgical phase should be improvement of facial beauty, relieve crowding of the arches and their co-ordination and to obtain a Class I molar relationship.

402 Dental Management of a Child with Neuroblastoma Undergoing Chemotherapy - A Case Report , Niranjana CN, Sahana Mahesh, Neha Gupta, Sreedevi Jayakrishnan and Megha Sanganeria
Neuroblastoma is a extremely rare developmental neoplasm arising from the embryonic sympathoadrenal lineage of the neural crest which affects young children whose prognosis becomes poor and poor as the age advances. Neuroblastoma arise as tumor from the tissues of the sympathetic nervous system, typically in the adrenal medulla or paraspinal ganglia, and thus can present as mass lesions in the neck, chest, abdomen, or pelvis. The clinical presentation is highly variable, ranging from a mass that causes no symptoms to a primary tumor that causes critical illness possibly resulting from local invasion, widely disseminated disease, or both. There is no standard dental treatment protocol for the management of neuroblastoma due to its poor survival rate and rarity. However, any dental treatment may follow a preventive and restorative protocol. Surgical procedures should be performed under supervision as it may trigger metastasis and further complications. This paper is a case report on a 4-year-old child who is suffering from stage 4 neuroblastoma- a malignant round cell tumor, which has a survival rate of 20%.

404 Exploring the Role of Platelet Derived Concentrates in Accelerated Orthodontics - A Narrative Review , Gayatri Ganesh and Thulika Tripathi
One of the major goals in the field of clinical research is the hastening of the regenerative process by waning the duration of the wound healing. Platelets play a crucial role in these procedures, as they act as reservoirs of cytokines and growth factors. Orthodontic tooth movement largely involves bone remodeling comprising of alternate cycles of bone resorption and deposition. The past decades have witnessed various attempts to accelerate the rate of this movement by various techniques leading to a decrease in the treatment time, a highly desired outcome by the patient as well as the orthodontist. The following review attempts to summarize existing literature concerning the application of platelet derived concentrates in dentistry and their potential role in orthodontics. The most commonly used platelet derived concentrates i.e. Platelet Rich Plasma (PRP), Plasma rich in growth factors (PRGF) and the Platelet rich Fibrin (PRF) have been described and compared to aid in future opportunities of clinical research.

415 Overview of Various Angled Abutments Commercially Available: A Review , Kothuri Naga Ravalika, Rahat Aisha Yasmeen, N Chandra Sekhar, Kollipara Soujanya and Valliammai Rajendran
The utilization of implant‑supported crowns and bridges has become a well‑established and preferred approach in treating com‑ pletely and partially edentulous states. An ideal implant position is requisite for obtaining good esthetic results and correct emer‑ gence of screw access hole. Commonly, due to insufficient bone volume, implant will be placed in available bone which leads to unfa‑ vorably placed implants. Once placed, such implants are restored by giving a cement‑retained prosthesis to avoid labial/buccal screw access holes witch are esthetically unpleasing. In such a scenario, a graftless solution would be using an angulated screw channel technology which tilts the prosthetic screw access hole emergence in a desirable direction that is more esthetic and acceptable. Angu‑ lated abutment system is unique and exclusive and are designed through computer‑aided design and computer‑aided manufacturing technologies. This system rectifies angulation issues with millimetric precision with full freedom of movement. This review article presents an overview of various types of angulated abutments commercially available. It highlights the features and angulation provi‑ sion of various commercially available angulated abutments.

417 Accidental Dislodgement of Separated Instrument in the Maxillary Sinus: A Unusual Case , Avisha Agrawal, Pratima Shenoi, Rajesh Kubde, Snehal Sonarkar, Gautam Badole, Vandana Kokane, Ankita Ramteke and Purabi Edbor
Root canal therapy consists of a cascade of scientifically-based technical procedures. Failure to follow the standard protocols and lack of knowledge can lead to a number of iatrogenic accidents which are collectively called “endodontic mishaps”. One of the most frequently encountered endodontic mishap is a separation of the endodontic instrument. Heroic attempts to remove separated instrument may lead to dislodgment of instrument in the periapical area. At times such instrument get dislodged in the maxillary sinus when treating upper maxillary molars and canines. Separated instrument in maxillary sinus, irrespective of their origin or nature, act as foreign body and Such objects should normally be removed at the earliest in order to minimize the likelihood of maxillary sinus complications. Studies have shown that some of the objects can cause chronic sinusitis because of the invasion of the sinus by highly virulent bacteria, while some remains asymptomatic. It is an uncommon finding to observe, an asymptomatic dental endodontic instrument in a position so close to the maxillary sinus without any oro-antral fistula formation and/or sinusitis attacks. This paper presents the case of a separated endodontic instrument which was pushed inadvertently in the maxillary sinus of a 41-year-old female patient

427 Hospital Dentistry: Dentist's Performance in the Pediatric Sector , Alexandre Ramos Braga
Hospital Dentistry is a dental specialty that aims to perform oral care and procedures in the hospital environment. Child hospitalization is considered a traumatic experience that leads the child to different feelings, such as anguish, anxiety and fear. The child will have to deal with different and noisy environments, lights, constant routine procedures, exposing him to great stress. The dentist's role in this context becomes very important, being part of the multidisciplinary team. The dentist, in the condition of examining children in a hospital environment, verifies the real need and the best opportunity to intervene in the oral cavity in order to maintain their healthy clinical condition as a whole. General health may be at risk if oral health is compromised, which can interfere with the recovery process. Treatment should include all dental specialties, considering a patient's clinical condition. The patient can be submitted to emergency procedures in the case of trauma and preventive procedures when the systemic condition worsens or is not affected by hospital infection

433 Healing of Periapical Lesions with Conventional Root Canal Treatment: A Case Report , Nayantara Sud
Infected pulp tissue is the major cause of periapical lesions, a majority of which are granulomas, radicular cysts or abscess. These lesions can only be diagnosed histologically. Root canal treatment or non surgical endodontic treatment is the treatment of choice in these cases without surgical intervention. Healing after the non surgical treatment takes place in about one year. In non surgical treatment emphasis is laid on thorough debridement, disinfection of the root canal system and obturation of canals. There are higher rate of healing in the anterior segment as compared to the posterior segment. The periapical index (PAI) is widely used measure to know the status of the periapical tissues. Thus, conventional endodontic therapy in combination with calcium hydroxide as an intracanal medicament contributed effectively in healing of periapical lesions in these cases.

444 Inflammatory Pathology of the Oral Cavity: Relevance in Oral Oncogenesis , Teresa Sequeira, Gonçalo Sousa, Eurico Monteiro and Augusta Silveira
Oral cancer is considered to be a growing public health problem and within head and neck cancer pathology, it is the most common. It is the 6th most common cancer in the world, corresponding to approximately 3% of all cancers. Despite the dedication and investment in this pathology, the advances in diagnosis strategies and the development of early intervention programs and treatments, aimed to be more targeted, more effective and less aggressive, the global survival rate after 5 years has remained worldwide at approximately 50% over the last three decades. The evaluation of Quality of Life stands out in this context as a key indicator, along with survival. We aim to review oral cancer etiology and discuss inflammation role in oral oncogenesis, considering its potential to modulate and amplify the impact of known risk factors. Additionally, we point out inflammation as predictive of poor prognosis in patients with oral cancer or at risk of developing it. Articles were collected from the PubMed, Bon, Elsevier, Science Direct databases, considering mainly the last 5 years of publication (2015 to 2020). The indexing terms used were “oral oncology and risk factors”, “oral oncology and epidemiology” and “inflammation and oncogenesis”. The role of the immune system and inflammation in the initiation, promotion and progression of oncologic pathology of the oral cavity has deserved maximum attention from the scientific community. It is clear that the presence of pro-inflammatory factors associated with immunosuppression are closely related to oral oncogenesis and poor prognosis. The chronic inflammation can contribute to modulate and amplify risk factors actions.

454 Oral Mucositis, a Side Effect of Hematological Malignancies Treatment , Boris Aurer
Oral mucositis is painful inflammation of oral mucosa and one of the most common side effects of chemotherapy, radiotherapy and hematopoietic stem cells transplantation. As the damaged mucosa is very painful, it causes problems in oral intake of food and beverages. Oral mucositis significantly impairs patients’ quality of life and may affect the outcome of hematological malignancy treatment. This paper presents a review of published data on the pathogenesis, clinical picture, complications, and therapy and prevention of oral mucositis in patients treated for hematological malignancies. The most significant factor for the development of oral mucositis is the type and intensity of antineoplastic therapy and use of agents that damage oral mucosa. Best prophylaxis is implementation of professional oral hygiene measures and motivation of patients to maintain good individual oral hygiene and avoid harmful habits which damage oral mucosa, such as alcohol and smoking, at least during antineoplastic therapy

456 Alternative Medicine in Dentistry: A Holistic Approach - A Review , Sunbul Tabrez, Neelkant Patil, Shobhit Kaswan and Lalita Chandna
Alternative medicine is a group of diverse medical and health care systems, practices and products that are not considered part of conventional medicine. It includes the use of dietary supplements, megadose vitamins, herbal preparations, special teas, massage therapy, magnet therapy and spiritual healing. They have lesser side effects and are also cost effective as compared to traditional medicine. The World Health Organization (WHO) has identified 150 systems of alternative medicine, out of which the most practiced ones are Ayurveda, Homeopathy, Naturopathy, Unani, Magneto therapy, Aroma therapy, Yoga, Massage therapy, etc. The alternative medical systems involve Western culture (Homeopathy and Naturopathy) and Non-Western culture (Ayurveda and Chinese medicine). We know that stress is a major causative factor for various psychosomatic disorders and oral diseases which can be prevented by holistic approaches. Many oral mucosal lesions like aphthous stomatitis, lichen planus, OSMF, leukoplakia, radiation mucositis have yielded great results for healing by the use of plant extracts. Even though the treatments are usually of longer durations, are unconventional and often lack errors in reasoning, but have yielded positive effects on various individuals. This paper emphasizes on the use of alternative medicine in dentistry

Several studies examining inflammatory response to its use generally demonstrated a mild inflammatory reaction. However, it may cause adverse reactions damaging bone and soft tissues either by direct contact after poor implementation or after ion diffusion. The severity and extent of the lesion depends on the quantity and concentration used, as well as on the time of contact. The following report describes a case of bone necrosis after a pulpotomy with calcium hydroxide in a temporary molar. Pathological analysis confirmed de diagnosis
459 Dental Calculus – Mere Ash Heap or Still A Mystery: A Review of Literature on Etiologic Significance of Dental Calculus , Swati Gupta, Ramakant Gupta and Manju Gupta
Chronic inflammatory periodontal diseases i.e., gingivitis and periodontitis are one of the most common afflictions faced by the human beings. They are considered to be infectious in nature having polymicrobial etiology. Dental plaque, which is a pool of these disease causing microorganisms has been the focus of researchers for the long time, and is considered to be the primary etiologic agent in disease etiopathogenesis. However, dental calculus which is a mineralized product of this plaque remains ignored and is considered merely as an ash heap of minor significance in etiopathogenesis of disease. Even though, there literature evidences of presence of intact and viable bacteria within the non- mineralized channels and islands in supragingival calculus from various studies. However, viability of bacteria in dental calculus and their role in disease pathogenesis still remained obscure. Therefore, this review intends to collate all the available literature and present the studies related to etiologic significance of dental calculus and investigation of the viability of bacteria in dental calculus along with their identification at one place and provide a way forward towards better understanding on etiopathogenesis and treatment of periodontal diseases

462 Monomorphic Adenoma: A Diagnosis or a Misnomer? A Review of Literature on Terminologies, Features and Differential Diagnosis of Basal Cell Adenoma , Swati Gupta, Ramakant Gupta and Manju Gupta
Basal cell adenoma, previously was termed by few authors as Monomorphic adenoma. The term “Monomorphic adenoma” was originally proposed for any benign epithelial salivary gland tumour other than benign mixed tumors. Monomorphic adenoma included tumours such as Warthins tumour, basal cell adenoma and canalicular adenoma. However, in the new 2005 WHO classification of salivary gland tumours the term “monomorphic adenoma” is not included and basal cell adenoma is considered as a separate entity. This paper intends to discuss the controversies regarding the terminology and classification of monomorphic adenoma along with diagnosis and differentiation of basal cell adenoma from other tumours

“Gender inequality” and “gender-based violence” are paradigms that one hope would be extinct by the 21st Century, two cultural concepts that our society tries to disguise as dated, but that still exist in the form of intimate partner violence in developed countries. In this literature review, intimate partner violence is described as a serious public health issue with high occurrence rates across the world, which requires an urgent implementation of protection and prevention measures.The extensive study of contents resulting from a search with the terms “intimate partner violence”, “domestic violence”, “preven-tion”, “violence against women”, “abuse”, “IPV” and “crime” allowed to gather information on preventive measures and integrate updated statistics of the World Health Organization (WHO) and of the Portuguese Association for Victim Support (APAV).The measures of protection and prevention of this type of crimes demand a change of moral and legal behaviours around the globe, as well as the implementation of algorithms of functional performance that can be applied by health professionals at patient-directed services. In this literature review, we will present the “RESPECT”, “AVDR” and “HELP” algorithms.
475 Leave no Tooth Behind - A Retreatment Case Report , Reaba Rebecca Thomas, Aby John, Shashi Rashmi Acharya and Archit Kedia
In a dental practice, it is becoming increasingly common to have endodontic cases which are seen to fail. The spike in the number of endodontic treatments carried out has consequently led to the increase in the number of failures seen and complications in their management. Endodontic retreatment is favored over dental extraction due to the desire to preserve the tooth and prevent adverse consequences in terms of functional and psychological effects that the loss of a tooth would have on a patient. This article showcases a clinical case that required endodontic retreatment to combat any complications that could arise and lead ultimately to the extrac-tion of the tooth. Considering that the tooth in question has a special importance with a physiognomic role, we resorted to its end-odontic retreatment and we have covered it with a porcelain fused to metal crown.

478 Evaluation of P53 in the Expression of Odontogenic Keratocysts , M Bousserouit and S Chbicheb
The odontogenic keratocyst also called epidermoid cyst, was first described by Philipsen in 1956; it develops at the expense of remnants of the odontogenic epithelium included in the maxillae. It is characterized by a large keratinization of its squamous border, aggressive growth and a strong propensity for recidivism. After the root cyst and the follicular cyst, the odontogenic keratocyst is the most common cyst of the maxillae.The odontogenic keratocyst has been a widely studied patholo-gy with a continually changing nomenclature of a "primordial cyst" to "odontogenic keratocyst". The aggressive nature of this unique jaw pathology has kept it in the limelight since its discovery with documented cases of cortical erosion, soft tissue involvement and extension in the skull base, orbit and infratemporal fossa. It's been a topic of debate for a long time, if the cysts could be as aggressive as this pathological entity.

481 A Journey from 3D to 4D in Orthodontics – A Review Article , Mamta Phogat and Tulika Tripathi
Orthodontic records are one of the main milestones in orthodontic therapy. Records are essential not only for diagnosis and treat-ment planning but also for follow-up of the case, communicating with colleagues, and evalu¬ating the treatment outcomes. Various 3D techniques such as such as Computerized Tomography (CT), Cone Beam Computerized Tomography (CBCT), Micro Computerized Tomography (MCT), 3D laser scanning, structured light technique, stereophotogrammetry or 3D surface imaging systems (3dMD), 3D facial morphometry (3DFM), Tuned Aperture Computed Tomography (TACT), and Magnetic Resonance Imaging (MRI) has cre-ated the potential for comprehensive facial evaluation. Recently, with the emergence of 4D a new dimension (motion) has been added to the imaging filed which has enabled capturing of dynamic facial movements. However, more elaborative and interdisciplinary research work needs to be done to explore the scope of 4D techniques. Therefore, the aim of this study is to review advances in 3D and 4d imaging with in the field of orthodontics.

488 Dental Fluorosis: The Impact on Young Adults’ Lives and Treatment Options , Seghir Arwa
Dental fluorosis is a cosmetic condition characterized by hypo mineralization of tooth enamel caused by ingestion of excessive fluo-ride during enamel formation. It generally appears as various degrees of tooth discoloration during growth. The severity of dental fluorosis depends on the dose administrated or ingested, age and the duration of the exposure. The most common form of fluorosis is characterized by small opaque white spots scattered over the tooth covering less than 25% of the surface. The severe form however is characterized by brown stains giving teeth a corroded-looking appearance where the discoloration is widespread. The purpose of this article is to study the impact of dental fluorosis on the psychological development of young individuals in addition to possible treatment plans

494 A Comparison between the Antibacterial Activity of Propolis and Ginseng Extracts on Porphyromonas gingivalis and Prevotella intermedia Isolated from Patients with Chronic Periodontitis , Heba A Shawky and Walid A Lotfy
The antimicrobial activity of ginseng extract was investigated in-vitro against 24 clinical isolates of Porphyromonas gingivalis and Prevotella intermedia. To our knowledge, there is a lack of researches on the evaluation of the antimicrobial effectiveness of ginseng extract on periodontopathic bacteria. We also compared the in-vitro antibacterial action of ginseng extract to that of propolis extract by agar diffusion method. The MIC values of ginseng extract against Porphyromonas gingivalis and Prevotella intermediawere 512 and 1024μg/ml, respectively. While the MIC obtained for propolis extract were 256 and 512μg/ml against Porphyromonas gingivalisand Prevotella intermedia,respectively. Moreover, the statistical analysis for the effect of ginseng and propolis extracts on Porphy-romonas gingivalis and Prevotella intermedia using student paired t-test revealed a significant difference between the two groups (p< 0.001). However, the anti-Porphyromonas gingivalis and anti-Prevotella intermedia mean activities of ginseng extract were lower than that of propolis extract by 1.32 and 0.17 AU, respectively. The results of the current study support the usage of ginseng extract as an adjuvant to periodontal therapy after proper in-vivo studies are performed.

497 Ameloblastoma of the Anterior Mandible - A Case Report , Anitha Krishnan Pandarathodiyil, Narendra Prakash Rai and Sukumaran Anil
Ameloblastoma is a neoplasm originating from the odontogenic epithelium. The tumor is considered benign despite its locally invasive nature. The pathogenesis of ameloblastoma involves the origin of the tumor from one of the following sources: remnants of dental lamina or remnants of the Hertwig’s epithelial root sheath, basal cells of the oral mucosa, developing enamel organ, and epithelial lining of an odontogenic cyst. It can exhibit different clinico-radiographic presentations such as conventional, unicystic and peripheral. Ameloblastomas occur most predominantly in the posterior mandible, in the molar-ascending ramus area, and are quite uncommon in the anterior jaws. Third to seventh decade is the usual age range for the occurrence of ameloblastomas with no gender predilection. A case of ameloblastoma which occurred in the anterior mandible of a 24-year-old female patient is presented. The clinico-pathological features, diagnostic criteria, and management of the case are discussed. The case is important because of its unusual presentation in the anterior region of the mandible and the diagnostic challenge it posed during the initial investigation.
498 Biocompatibility of Dental Implant: Revised , Nagy Abdulsamee, Ahmed Elkhadem and Passant Nagi
A dental implant is a good example of the integrated framework of science and technology in multiple disciplines, including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering, among different dental materials and their effective applications. There are important features for dental implant systems, like all other dental materials and products, since the surface of dental implants is directly in contact with vital hard/soft tissue and is sub-ject to both chemical and mechanical bio-environments. Such appliances should include, at the very least, biological compatibility, mechanical compatibility and morphological compatibility with the important tissues surrounding it. Most of the dentists know well biological compatibility but overlook mechanical compatibility, and morphological compatibility. Therefore, this review throws a deliberate sight on these points.
499 Pyogenic Granuloma - A Simple Treatment Approach with Sclerotherapy , Shalini Subramanyam and Peeyush Shivhare
Pyogenic granuloma (PG) is a benign exophytic vascular tumor, which is actually a reactive inflammatory mass of blood vessels with few fibroblasts within the mucosa or skin, was first reported by Hullihen in 1844. Variety of treatment options such as surgical excision, laser treatment, electrodessication, chemical cautery, cryosurgery, intral-esional steroid injection etc. are available, but many a times, recurrence has also been reported.Sclerotherapy is defined as the “targeted elimination of small vessels, varicose veins and vascular anomalies by the injection of a “sclerosant”. It offers an alternative to conventional methods like surgery, lasers, radio frequency ablation and electrodesiccation procedure with success and less chance of recurrences.Herein, we present a case of 22 years old female with a clinical diagnosis of PG, treated with intralesional 0.2 ml of 3% sodium tetradecyl sulfate (STS). The lesion healed completely at the patient’s 3rd visit and recurrence was not reported till the patient was followed up for one year.

506 Human Immune Response to COVID-19 Infection and Potential Role of Chloroquine Family of Drugs: A Review , Sunita Singh, Chandrashekharaiah PS, Vishal Paul, Santosh Kodgire, Shivbachan Kushwaha, Debanjan Sanyal and Santanu Dasgupta
In December 2019, COVID-19 disease outbreak started from Wuhan, China. World is still, witnessing a massive morbidity and mortality due to the pandemic caused by novel coronavirus severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). This newly discovered virus enters inside and infect the body cells through the angiotensin-converting enzyme 2 (ACE2) receptor. The S1 protein of SARS-CoV-2 binds to the ACE2 receptor which results in endocytosis and transfer of virus into endosomes of body cells. Entry of SARS-CoV-2 results in activation of the innate immune responses first followed by the adaptive immune responses. The effective host immune responses are crucial to control and prevent the viral infections. However, the excessive production of pro-inflammatory cytokines and decrease in the number of T-lymphocytes are the major reasons associated with severity of COVID-19. Therefore, anti-inflammatory drugs such as Chloroquine (CQ) and hydroxychloroquine (HCQ) may play a crucial role to control and prevent the progression of disease by immunomodulation. The treatment responses of COVID-19 patients to these drugs have been found positive in some cases and clinical studies are underway for evaluating these drugs for the same. Moreover, regulatory bodies such as Food and Drug Administration (FDA) and European Medicines Agency (EMA) have recommended usage these drugs in emer-gency and chronic situation to treat critically ill COVID-19 patients under doctor’s supervision. The national task force (NTF) set up by Indian Council of Medical Research, has recommended high risk individuals to take HCQ for prophylaxis. This review summarizes human immune response and various aspects of CQ and HCQ with special reference to COVID-19.
507 Helicobacter pylori Treatment , Abdulaziz Radhi S ALjohni, Bassam A Aljohny, Sultan Saud Alahmad, Abdulaziz M Hakami, Omar Alfaroq and NA Al-Tayyar
H. pylori the Helicobacter genus, is found in over 80% of cases of gastric cancer in developed and emerging nations. H. pylori is gram-negative and is responsible for gastroduodenal diseases as the recognized major human bacterial pathogen. It will remain in the stomach for life until acquired and colonized. Acute and chronic gastritis, peptic ulcer disease, gastric adenocarcinoma and lymphoid tissue tumor combined with mucosa are found in a limited population of carriers (MALTA). In certain instances, H. The pylori infection is absolutely asymptomatic or has signs that are nearly imperceptible. H. pylori are different depending on the form of media, blunted/rounded ends in gastric biopsy specimens, but in fresh culture on agar medium they are rod-like and spiral shape when coccoid is on prolonged culture.Infection therapy depends on a mixture of antimicrobial agents and antisecretory agents, and the bactericidal activity of anti-microbial agents includes an elevation of gastric pH by antisecretory agents. Alternatively, although the mechanism of action is not yet apparent, to enhance eradication of H, phytomedicines and probiotics have been used H. pylori. The effect of antimicrobials and antisecretory agents is not only based on their pharmacological action, but also on their pharmacokinetic properties. Several anti-microbial agents have been used for H, including amoxicillin, clarithromycin, levofloxacin, metronidazole, tetracycline, rifabutin and compounds containing bismuth H. pylori

512 A Novel Reconstruction of a Large Mandibular Cystic Defect by Bone Graft Substitute , Radhika Shashank Tayshetye, Nitin Bhola, Anendd Jadhav and Chirag Patil
Odontogenic cysts are the most common lesions in the oral and maxillofacial region. The commonly chosen treatment approach for it is enucleation and extraction of the involved tooth, if required. To decrease infections and for spontaneous bone regeneration, various bone grafts are increasingly investigated for filling the defect. Autogenous bone graft being the gold standard has its various shortcomings which lead to the search for allogenous, xenografts and alloplasts. Surgical grade calcium sulfate is considered a con-venient, safe and readily available bone graft substitute with consistently successful results. This uniqueness of Calcium Sulphate has increased its purpose in the void filling. The purpose of this paper is to present a case of a large Dentigerous Cyst (D.C.) which was successfully managed by antibiotic impregnated Calcium Sulphate as a Bone Graft Substitutes in post cystectomy defect and exhibit its spontaneous bone regeneration radiographically

Periodontal disease is the most prevalent disease across the world. It is an inflammatory disease involving progres-sive and episodic loss of the periodontal attachment apparatus with tissue destruction consequentially arising out of host response against bacterial antigens as well as irritants leads to loss of alveolar bone and supporting the teeth. Chronic periodontitis causes various types of bony defects, among them intra-bony defect is most common. There are two primary treatment modalities for treat-ing periodontitis and associated changes, including non-surgical and surgical periodontal therapy.
516 Clinical Evaluation of Efficacy of 1.2% Atorvastatin Loaded in PRF with Collagen as a Barrier Membrane in Alveolar Ridge Preservation after Mandibular Molar Extraction , Kankipati Amrutha, Rupasree Gundala, YSHS Chakravarthy Reddy, Dalli Bharath Simha Reddy, Putta Sri Krishna Chaitanya and Patcha Harika
Extraction of teeth accounts for loss in height and width of the tooth dependent alveolar process, which results in a significant structural and dimensional changes leading to the atrophy of the residual ridge. Most of the resorption occurs during the first 3 months of healing, although dimensional changes can be observed up to 1 year after tooth extraction. Therefore, regenerative or other surgical intervention appear to arrest the bone resorptive process, to restore the alveolar process thus preserving the natu-ral contours and preparing the anatomical surroundings for the suggested prosthesis.To evaluate and compare the efficacy of 1.2% Atorvastatin loaded in PRF with collagen as a barrier membrane in alveolar ridge preservation versus controls after mandibular molar extraction, by measuring the following clinical parameters like relative coronal level of gingiva, mucogingival junction, crest of socket, socket depth, socket width at the most coronal level and to evaluate bone density changes radiographically by QDSR (Quantitative Digital Subtraction Radiography) technique in 1.2% Atorvas-tatin group and controls.

MALDI or Matrix Assisted Laser Desorption Ionisation has emerged as a powerful, versatile imaging modality that has since its advent created ripples in the scientific community. The major reason for its success is the ability of this system to criti-cally analyze, study the macromolecules and detect their presence in thousands of samples simultaneously. Moreover, because of its soft ionization techniques, it is now possible to study the biomolecules which would have previously decomposed due to inappropri-ate ionization skills. It is also the first of its kind to bring the world of mass spectrometry and the world of histology under the same banner creating a modality that is currently transforming the way we have understood the world of bioinformatics. Now it is possible to study a broad spectrum of analytes in unprecedented detail most of which until a few years ago had been completely unknown to the scientific communities.
520 The Advantages of Saliva Sampling Method for Diagnosis of COVID 19 , Amera K Alkaisi and Salma B Abdo
Several tests for many persons have to be conducted in order to control the pandemic and prevent the possibility of transmission of (Covid -19) to health care workers and other patients. The main aim of this study was to detect the importance of saliva sample for early diagnosis of Corona virus 2019 (COVID-19). Saliva sample considered as an alternative for diagnosis of COVID-19 as salivary gland found to express surface receptor angiotensin converting enzyme II, (ACE2) a receptor that plays a key role within the entry of SARS Corona Virus-2 (SARS-CoV-2) into the cell. The sample can be self-collected from the entrance of the oral cavity easily, in a way the risk of virus transmission to healthcare personnel can be minimized avoiding the use of protective equipment. There are several ways for collection of saliva, such as spitting out, directly from salivary duct gland and collection with sponge- like device. The analysis of Saliva can be used to detect oral cancer, dental caries, periodontal diseases, diabetes, breast cancer, and lung cancer. The saliva polymerase chain reaction (PCR) test demonstrated high sensitivity comparable performance to the current standard naso-pharyngeal and throat swabs. In addition, saliva could be used for monitoring viral clearance, as it contains the highest live COVID-19 viruses and viral load during the first week.

523 Challenging Issues in Development and Integration of Modern Kinematics with Components and Images Obtained from Different Sources in Biomechanical Applications , Yevsey Gutman, Nadejda Krasnorutskaya and Gary Gutman
In spite of the existing and successful development of CAD/CAM methods for mechanical applications, the ability to model the motion of biomechanical systems still presents many challenges. The reason for those challenges is in complexity of the nature of components to be used for the projects, specifically based on the origin of the parts: where are they coming from. Depending on the biomechanical application it could be as many as three different sources for the parts to be included in to the “assembled” system. They are: (1) “standard” parts which can be designed using the conventional CAD system, (2) parts which can be obtained only through the process of surface scanning; and (3) components which are the product of CT scanning with volumetric property. An Advanced method is discussed here which can deal in case of biomechanical systems to address the weaknesses of the Standard Ap-proach in use for purely mechanical systems.

In the past 40 years, Chlorhexidine has been extensively studied and used for plaque control in dentistry. It is a bisbigu-anide and is considered as a gold standard antiplaque agent due to its prolonged substantivity. It has a limited use period due to its known side effects such as extrinsic stains and alterations in taste sensation. On the other hand, mouthwashes made from the herbal and plant sources containing natural occurring active ingredients provide a gentle, harmless and a trustworthy option. P. granatum and S. persica are such plant products that are known to have antiplaque effects. Moreover, their use also overcomes the side effects caused by the chlorhexidine.
525 A New Microscope to Tiny Tumours - A Systematic Review , Kumar Sougata, Prerana G and and Gaurav
The authenticity and expertise of various imaging systems have been usually restricted as most of these imaging systems cannot visualize minute tumours. This is the reason certain cancers such as ovarian cancers and breast cancers are only diagnosed in their terminal stages. Moreover, despite landmark advances in varied areas of diagnostic imaging the detection and screening for most of these tumours remain poor. As the world is constantly being woven in the cocoon of technology it thereby be-comes imperative to develop and come up with better diagnostic modalities than the ones available to us. Also, with the global cancer burden constantly on the rise, various new imaging modalities come up as new waves in the field of radiology.Aim of the Study: To assess the significance of imaging systems in the diagnosis of small-sized tumours.
526 Role of Corticobasal Implants in the Rehabilitation of Dentoalveolar Trauma , Ashish Chakranarayan and Priya Jeyaraj
Management of dentoalveolar trauma often poses a unique challenge in terms of a need to replace both dental and bony hard tissues. In cases with loss of bone along with tooth the crestal implant-based management is often delayed due to insuf-ficient bone. Corticobasal implants offers a comprehensive management for such conditions. Three cases of dentoalveolar trauma were managed and rehabilitated successfully at our centre using cor-ticobasal implants. No adjunctive bone reconstructive or regenerative procedure, such as bone grafting or distraction were carried out to facilitate implant placement.
527 Salivary Proteomics and Transcriptomics: An Evidence-based Systematic Review , Shivangi Pandey, Kuntalika Sarkar, Kumar Sougata and Gaurav
Proteins are considered to be the building blocks of our bodies and they are known to harbor a vast array of informa-tion, the spectrum of which ranges from the knowledge of physical or pathological conditions to provide us with a pool of biomarkers. Saliva at the same time forms an indispensable part of the oral cavity and with recent researches, it is known to be a huge source of these proteins. As biochemical and molecular technologies are developing each day the gradual intersection of the above two men-tioned sources (saliva and proteins) becomes an inevitable pool of knowledge which if carefully studied could throw open future doors of non-invasive diagnostic procedures encompassing multitudes of systemic and metabolic diseases. In this literature review, we have tried and explained the two important biomarkers present in saliva namely proteomes and transcriptomes, and how these are eventually co-related and could serve us to understand the bigger picture of quick and efficient diagnosis.

529 “Trail” in Cancers - Time to Curb the Crab: A Meta-Analysis Research , Ayushi Bhargava and Gaurav
TRAIL (tumor necrosis factor related apoptosis inducing ligand) is the one of the recently developed method for curing cancer. The method demonstrates modified lipid nanoparticles which attaches to TRAIL and E selectin all of which coats the WBCs. The designed nature of modified leukocytes is cytotoxic and shows homology to TNF leading to targeted death of cancerous cells without harming normal healthy cells of one’s body. These modified leukocytes designed using body’s own defenses track down and induces apoptosis of absconding cancer cells. This approach shows large potential for patients with metastatic cancer as TRAIL coated leukocytes occur innate. Since current therapies have lot of disadvantages with it, which allows TRAIL therapy to be investi-gated at a large scale
530 COVID-19, An Eye Opening Pandemic - A Mini Review , Peeyush Shivhare, Shalini Subramanyam and Prapulla Sridhara Murthy
Corona virus disease (Covid-19) is an infectious disease of newly discovered Corona virus variant towards the end of the year 2019. It quickly infected thousands and millions of people all over world, spreading widely like a wildfire. By the end of January 2020, World Health organization declared the outbreak as global health emergency and later in March 2020, they announced COVID-19 as a global Pandemic. The uniqueness of Covid -19 was how little was known about the disease. Hence, it was a battle for many research-ers, scientists, doctors, dentists, governments and the masses to understand the ongoing Pandemic situation. Although predomi-nantly COVID-19 affects lungs, it did have manifestations on other parts of the human body. Here in this mini literature review, we tried to shed some light on basic aspects of COVID-19 along with oral manifestations, pathophysiology from the dental aspect along with recent advances in Vaccine and the ongoing clinical trials. We encourage active participation of Dentists in promoting the aware-ness and preventing the spread of covid -19 by understanding and equipping themselves with recent updates on this very disease.
531 Metagenomics: Rejuvenating Oral Medicine: Concepts Recultured- A Meta-Analysis Research , Shivangi Pandey, Shailaja Kushwaha, Pallab Roy and Gaurav
Metagenomics is the study of genetic material which has been directly taken from environmental samples. It is also known as environmental genomics, ecogenomics or community genomics. The initial molecular work in this field was done by Nor-man R. Pace and colleagues, they used PCR to explore the diversity of ribosomal RNA sequences. The knowledge that was gathered from these explorative studies led Pace to propose the idea of cloning DNA directly from environmental samples in the early 1985. Metagenomics as said can be a powerful tool to view the microbial world and its hidden diversity of microscopic life. Metagenom-ics offers immense potential to understand the entire world of living creatures around us. Since DNA sequencing shows a fall, when compared to metagenomics, which now allows microbial ecology to be investigated at a much larger scale and detail than before.
532 Geometric Analysis of Mesio-buccal Root Canals of Mandibular Molars Prepared by (M-pro), FlexMaster and RaCe File systems: An In Vitro Study , Mahmoud Bahaa Eldin Mohammad Gouda, Reem Ahmed Lutfy and Shaimaa Ismail Gawdat
The aim of this study was to evaluate and compare 3 file systems; M-Pro, FlexMaster and RaCe in preparing moderately severe curved mesiobuccal canals of human mandibular molars regarding: transportation of the canal, the centering ability and change of radius of canal curvature, using cone-beam computed tomography (CBCT) scanning. A total of fifty-one mesiobuccal root canals of extracted human mandibular first and second molars with the angle of curvature ranging 20-35 ͦ (according to Schneider) were collected and divided into three equal groups. After access cavi-ties preparation and working length determination, distal roots with the respective part of the crowns of all samples were sectioned at the furcation level and discarded. Samples were mounted in acrylic resin molds and then CBCT scanning was done pre and post instrumentation using the same scanning parameters. Root canal preparation was done according to the manufacturers' instructions of each NiTi system. The pre and post-images were superimposed using a fusion module of OnDemand 3D App software to measure the dentin thickness at root canal levels (2, 3, 5 and 8 mm from the tooth apex). Canal transportation and centering ability were re-corded according to formula introduced by Gambill., et al. while the change in the radius of canal curvature was recorded following Estrela., et al. Data was tabulated and statistically analyzed.
533 Pattern of Mandibular Third Molar Impaction in North-Central Nigeria: Panoramic Radiographic Assessment , Seidu Adebayo Bello and Nathan Ukuoghene Ikimi
The third molar is the most common tooth in the mouth that fails to erupt partially or completely into its functional position and this could be because of an impediment on the eruption path. Management of impacted third molar is usually by a surgical procedure extraction and successful treatment is enhanced with the aid of a radiograph which is either the periapical x-ray or the panoramic radiograph. This study reports on a large population of patients, using the panoramic radiograph to evaluate and compare with the periapical radiograph the various pattern of the impacted mandibular third molar presented in north central Nigeria.A retrospective examination of digital panoramic radiographs obtained from patients who had surgical extractions of impacted mandibular molars between March 2016 to April 2020. The data obtained were analysed using the Statistical Packages for the Social Sciences (SPSS) version 20. Chi-square test was done to determine statistical significance which was set as P < 0.05.There were 366 (55.8%) male and 289 (44.1%) females, with an age range of 16 to 70years and a mean age of 34 ± 12.5 years. Impaction was found on one side of the mandible in 30.3% and on both sides of the mandible in 69.5% of the patients and the most common type of impaction according to Winter’s classification was mesioangular impaction and found more common among males in this study at 43.4%.Our results here gave better clarity with the use of the panoramic radiographs and therefore strongly recommends the orthopan-tomogram (OPG) before any mandibular 3rd molar extraction is done.
534 Labial Type Dens in Dente: A Rare Case Report , Manisha D Yadav, Bhakti Patil Soman and Deepa Das
Dens Invaginatus, also known as dens in dente a rare developmental anomaly affecting human dentition. It arises as a result of invagination into the surface of tooth crown or root before calcification has occurred. Most commonly affected teeth are permanent maxillary lateral incisors and is usually seen on the palatal aspect. In the present case report it was, rare to be seen on the labial as-pect of maxillary central incisor. This anomaly may increase the risk of pulp disease and can potentially complicate treatment due to its aberrant anatomy thus, posing a diagnostic challenge. Radiography plays a vital role in diagnosing such developmental anomaly. Compared to conventional radiograph Cone Beam Computed Tomography (CBCT) plays an invaluable role in the diagnosis of the ex-tent dens invaginatus and in appropriate treatment planning. This case report highlights the role of CBCT in the diagnosis of various types of dens in dente.
535 Unusual Clinical Presentation of Oral Leukoplakia: Case Report and Review of Literature , Lavanya Pasalkar, Shrutika Sonawane, Vikram Khare, Pallavi Channe
Oral cancer is the most commonly seen malignancy in Indian males and leukoplakia is the commonest of all precancerous lesions which can transfer into oral carcinoma. The estimated global prevalence of oral leukoplakia is 2.60% with 0.13 to 34% malignant transformation rate. It has been proved that clinical type, grade of dysplasia and age are associated risk factors with malignant transformation. A 38 yrs male patient found to have a tiny solitary well defined white plaque like lesion on buccal mu-cosa hardly 2 mm x 3 mm which was unnoticed by the patient till then. Surface of the lesion was raised, rough and wrinkled. It was non-scrapable. Patient had tobacco and gutka chewing habit with cigarette smoking since 5 years. Though the size of lesion was too small considering all the factors provisional diagnosis of homogeneous leukoplakia was given. An immediate excisional biopsy was performed. Histopathological examination revealed oral leukoplakia with moderate dysplasia. Dysplastic changes could have been a major risk factor for malignant transformation. Early diagnosis and excision of lesion ensured good prognosis.

540 Evaluation and Compare Effectiveness and Durability of ICON Resin Infiltration and Acidulated Phosphorus Fluoride in Treatment of Post-Orthodontic White Spot Lesions , Mohamed Said Ibrahim, HalaMunir2, Fady Hussein and Dalia El Boghdady
Randomized clinical trial was conducted to evaluate of the effectiveness and durability of Icon resin infiltration compared to acidulated phosphorus fluoride in management of white spot lesions. Eighteen patients with an age range of 12 - 25 years which included both males and females were enrolled in this study. The scoring criteria according to the lightness scale were graded from 0 to 100. Patient satisfaction score was recorded using a visual analogue scale from 0 to 100 according to patient's own evaluation for each quadrant before, after intervention and after 3 months follow up. A significant improvement of WSL esthetics was found im-mediately after Icon resin application by 18.2% and 18.8% in both upper and lower arches respectively. However, after three months follow up it was significantly reduced to 15% in the upper and 17.2% in the lower arches. A slight improvement in esthetics of white spot lesions was found immediately after APF application by 7.2% in both upper and lower arches while, after three months follow up period it significantly improved from 7.2% to 10% Patient satisfaction scores revealed that before application, there was dissatisfac-tion among the patients of the perception of their teeth. However, greater satisfaction scores were found immediately after Icon resin and APF application and after 3 months follow up. This results suggest that Both Icon resin and acidulated phosphorus fluoride gel improved esthetics of white spot lesions

India’s growing aging population poses greater challenges for the dental clinicians. Undergraduate dental education programs must include geriatric dental education to train students to meet these challenges. Dental colleges in India, currently do not provide a formal geriatric dental education. Introduction of a structured educational intervention can bring about a change in the attitudes and expectations of students regarding the aging, which in turn has been known to affect the treatment rendered. Aims: To evaluate the change in the attitude and expectations of the undergraduate dental students when introduced to a specially developed Geriatric Education Program (GEP) ii. To qualitatively analyse the students’ perceptions and experience about the intro-duced GEP in their curriculum.
551 The Impact of COVID-19 on the Environment. Short Review , Nagy Abdulsamee, Ahmed Elkhadem and Passant Nagi
The COVID-19 disease has recently spread as a global pandemic, posing serious threats to mankind. The World Health Organiza-tion (WHO) has issued guidelines to assist countries in reducing the spread of the virus to the general public, including the use of masks, hand hygiene, social distancing, and the shutdown of all kinds of public transportation. These circumstances resulted in a significant drop in global economic activity, but there were also indirect environmental benefits such as improved global air quality and reduced water pollution. Because there are no clinically proven drugs or vaccines for COVID-19, face masks are currently part of a comprehensive package of prevention and control measures that can limit its spread. Face masks are typically made of non-renewable petroleum-based poly-mers that are non-biodegradable, dangerous to the environment and cause health problems. This review demonstrates the extensive use of the face mask and how it affects human health and the marine ecosystem positively as well as negatively. It has become a great challenge for the government sectors to impose strict regulations for the proper disposal of the masks as medical waste by the public to minimize their negative effects. Neglecting the seriousness of this issue may lead to the release of large tonnes of micro-plastics to the landfill as well as to the marine environment where mostly end-up and thereby affecting their fauna and flora population vastly
552 Gorlin-Goltz Syndrome: Literature Review and Report of Two Clinical Cases , Juliane Maria Iagnes Prestes and João Luiz Carlini
The Gorlin-Goltz Syndrome, also known as Basal Cell Nevus Syndrome, is characterized by the triad of multiple basal cell carcino-mas, keratocystic odontogenic tumors, and skeletal abnormalities. However, due to its variable expressiveness, other manifestations may occur, making diagnosis difficult. In this article, we aim to recall the signs and symptoms that can be identified in the bearer of this syndrome by reviewing the literature, alerting the health professional, and discussing their diagnostic process, illustrating it with two clinical cases from the Federal University of Paraná (UFPR). It was also intended to indicate its adequate treatment, since the management of this condition requires the monitoring of a multidisciplinary team in the long term, due to the involvement of multiple systems, the high rate of recurrence of the lesions, and the late appearance of carcinomas.
553 Accuracy of 3DPrinted Windowed Bracket-Positioning Guide Versus Thermoformed Transfer Tray for Orthodontic Indirect Bonding: A Randomized Clinical Trial , Amany El-tantawy, Amr Abouelezz, Amr Ragab El-Beialy and Mai Hamdi Aboul Fotouh
To compare the digital 3d printed window transfer tray and the conventional thermoformed tray regarding the accuracy of transferring the attachments.A randomized clinical trial was performed the two different bonding techniques, 144 attachments were recruited in this study. In the control group, the orthodontic attachments were bonded to working models and scanned with an intraoral scanner to make STL file of the working model. The transfer tray was then fabricated in order to transfer the orthodontic attachments in to the patient’s mouth. While in the intervention group, the teeth were scanned with the same intraoral scanner to produce the digital model on which the virtual attachments are placed using the OrthoAnalyzer software. The tray was designed and printed with win-dows opened gingivally. The attachments were fitted into their positions through the windows of the tray. Then intraoral scanning for both groups was done to obtain STL models after bonding. Superimposition of the pre and post STL models was done using 3Shape OrthoAnalyzer software to measure the angular deviations (tip, torque and rotation).
554 The Effect of Desensitizing Agents on Open Dentine Tubules- An , Baruch Nurit and Zilberman Uri
Dentin sensitivity can be treated by blocking the exposed dentinal tubules or by interrupting neural response for pain stimuli.To analyze in vitro the plugging effect of open dentin tubules by three desensitizing tooth pastes and a desensitizing agent.V shaped cavities were made on the buccal surface of 18 extracted premolars. On each group of 3 premolars each, the exposed dentine was brushed with water (control), 3 desensitizing tooth pastes (Oral B-gum and enamel repair, Sensodyne-dual care, Colgate-sensitive pro-relief ), a parodont expert toothpaste (Meridol) and a desensitizing agent (Riva Star desensitizing agent) twice a day for 30 seconds, for 10 days. Two days after the last brushing, the dentin surface was analyzed with SEM to observe the effect of the agents on dentine tubules. Using the Energy Dispersive X-ray Spectrometer (EDS) program the ion content of the dentine surface (%WC) was examined, in order to analyze the effect of toothpaste ingredients on the dentine.Results: Tooth-brushing with water, Meridol and Sensodyne dual-care left the dentine tubules open with no plugging. Colgate-sen-sitive pro-relief toothpaste caused plugging of 40% of the tubules, while Oral B gum and enamel repair applied a plugging material on 100% of the tubules. Riva Star covered the dentin with amorphic material. The ion content of the dentin surface after using Oral B showed apposition of zinc, tin and titanium, Colgate showed apposition of zinc and Riva Star showed apposition of fluorine, alumi-num, silver, iodine and tellurium on the dentin.

559 Van Der Woude Syndrome: Report of a Case , Krutarth Kshirsagar, Anendd Jadhav, Rajanikanth Kambala and Nitin Bhola
Van der Woude Syndrome (VWS) is a genetic disorder caused by a dominant mutant gene on an autosome which is associated with lower lip pits and clefts of the lip and/or cleft palate. Considerable heterogeneity regarding expression of the disorder constitutes a rare developmental malformation as congenital pits of the lower lip. Commonly associated characteristic features with lip pits are submucosal palatal clefts, velopharyngeal insufficiency and genitourinary or cardiovascular anomalies. The association of congenital pits with clefts is observed in about 50% of cases. They are usually located on either side of the midline of the vermilion portion of the lower lip, symmetrically and bilaterally. They may also present as unilaterally, medially or bilaterally asymmetrical structures. Surgical excision is the best-choice of treatment for lip pits. As the presence of salivary tissue in any residual tract increases the pos-sibility of cyst formation, excision of lip pits is crucial in ensuring proper removal of the entire tract. In the present case scenario fistula repair was done using tongue flap and surgical excision of lip pits was performed using wedge incision. The purpose of the current case report is acquiring adequate knowledge about proper evaluation and treatment along with genetic counselling which will provide a proper guide for management of such cases

Comparing the difference between two types of indirect bonding trays (single sheet versus double sheets) regarding chairside time and accuracy of transferring orthodontic attachments in all 3 planes of space using 3D scanning and superimposition.A randomized controlled trial (split mouth design) compared between the single versus double transfer trays tech-niques was performed, 6 patients with fully erupted full set of permanent teeth were recruited in this study. 84 attachments were bonded to the maxillary teeth from central to second molar for both groups. After placement of the attachments on the working model using water soluble glue regarding the vertical and horizontal reference lines, the model was sprayed with titanium dioxide powder then scanned with intraoral scanner and preoperative STL file was saved. The single and double transfer trays were fabricated, one on each half of the working model then the trays were divided, trimmed and prepared for bonding procedure. The attachments were transferred to the patient’s dentition using the two techniques, then the patient’s dentition with attachments were scanned with the same intraoral scanner and post- transfer STL file was saved. The chairside time for each group was measured using stopwatch. By using the Geomagic qualify version 12, the two STL files were superimposed and the deviations were detected for 7 values, 4 linear measurements (total linear, mesio-distal, occluso-gingival and bucco-lingual) and 3 angular measurements (tip, torque and rotation). The attachments failure rates were recorded immediately. A visual analog scale was given to each subject to measure their satisfac-tion towards the both used indirect bonding techniques.

596 Reconstruction of Surgical Defect in Mandible Using Patient Specific Implant - A Case Report , Shweta Murlidhar Patil, Nitin Bhola, Chinmay Ghavat and Anchal Agarwal
The odontogenic keratocyst (OKC) is a commonly occurring developmental cystic lesion of the jaw with a predilection for males (1.3:1) in the 2nd - 3rd decade [1]. It accounts to approximately 11% of all cysts of jaw and occurs most commonly in the posterior body or ramus of the mandible [2]. It’s destructive nature and propensity for recurrence necessitates aggressive treatment to ensure low recurrence rate [3]. Autogenous bone has been a gold standard for reconstruction. Replacement of mandibular bone has been performed by using free fibula, scapula, iliac crest grafts etc. It is associated with donor site morbidity and difficulty to shape the au-togenous bone in areas with curvature. Patient Specific Implants has revolutionised the reconstruction ladder and is a treatment mo-dality for these arduous cases. In the present case of OKC a segmental resection with disarticulation was performed. PEEK (Polyether Etherketone) implant was used for reconstruction.
