The purpose of this study was to compare patient’s perception on gingival depigmentation using diode laser and scalpel technique. 20 Patients took part in the study, control sites were treated with a scalpel blade and test sites were treated with Diode laser in contact mode. VAS scale was used for pain perception after surgery. A questionnaire was used to assess esthetics change postoperatively at 1 week and at 3 months, patient’s expectation of the procedure and repetition of treatment if needed. 90% subjects complained of no pain in the laser group whereas 45% subjects complained of no pain in scalpel technique which showed VAS scale to be statistical significant between the two groups. Comparison of patient opinion regarding the esthetic change, patient expectation and retreatment of the two surgical procedures were at par with one and another. The application of semiconductor diode laser and scalpel procedure appeared to be an effective treatment for gingival melanin hyperpigmentation.
