Abstract


To evaluate the prevalence of malocclusions and the necessity of orthodontic treatment in a population of Central Romania Region. Method: A retrospective study, analyzing the files and dental cast of 417 patients aged between 12 and 29 years, was performed between 2010 and 2013, on patients from both urban and rural areas. Inclusion criteria: clinically healthy patient, no orthodontic treatment in antecedents. A number of 349 male and female patients were consulted for establishing the presence of malocclusions and their distribution according to sex and origin. Results: Out of the 295 patients with malocclusion, 25.08% evidenced class I Angle; 65.76% - class II; 9.15% - class III. A higher frequency of class I and II malocclusions was recorded in females, comparatively with males: class I - 66.22% females; class II - 68.04%. Class III malocclusion were more frequently observed in males: 55.56%. 78.31% of the cases from urban areas presented one of the three dental classes. Calculations (p=0.00040) evidenced a statistically significant relation between the presence of dental malocclusions and the area the patients came from. All three types of malocclusions had a higher frequency in the females coming from urban areas. Conclusions: A higher frequency of malocclusions (except class III), even if statistically insignificant, is recorded in females. No statistically significant differences were noticed between the origin region and the type of malocclusion, and/or between the type of malocclusion in females or males and their place of origin.The only statistically significant correlation is the one between the presence of malocclusion and the place of origin.
