Gingival hyperpigmentation has been a major concern for a large number of patients visiting the dentist. Clinicians are challenged for attending to and correcting this biologic, esthetic and functional problem. Melanin, a non-hemoglobin derived brown pigment, is often abnormally deposited in the basal and suprabasal cell layers of gingival epithelium due to which the gums appear black particularly in patients having a high smile line. Several depigmentation procedures like scalpel surgery, gingivectomy with free gingival autograft, electrosurgery, cryosurgery, laser therapy using Nd:YAG, diode or CO2, abrasion with diamond bur, chemical agents like 90% phenol and 95% alcohol have been employed for removal of melanin pigmentation.
The present case report describes two distinct surgical depigmentation procedures: scalpel blade surgery and semiconductor diode laser for complete removal of gingival pigmentation, tissue healing following the surgery and fulfillment of patient centered outcomes like satisfaction, pain intensity assessment and adverse events. Diode is a solid state semiconductor laser that combines Gallium (Ga), Arsenide (Ar) and other elements like aluminum (Al) and Indium (In), converting electric energy into light energy. In this report both the surgical techniques have shown excellent results, however scalpel blade surgery showed marginally better results in terms of tissue healing and esthetics.
