Abstract
Aim and Objectives: To compare effectiveness of surgical blade, electrosurgery, free gingival graft (FGG), and diode laser for the management of gingival hyperpigmentation. Materials and Methods: Forty patients who were concern for the unesthetic anterior gingival due to melanin hyperpigmentation were treated in this study. Of 40 patients, 10 patients were treated using surgical blade, 10 by electrosurgery, 10 using FGG, and 10 patients using diode laser. The gingival hyperpigmentation was recorded preoperatively and 3 months postsurgery by measuring area of hyperpigmentation in square millimeters and severity of hyperpigmentation using Dummet's oral pigmentation index. Results: Healing was uneventful and required no supportive therapy. No patients experienced severe pain during or postsurgically. Mild discomfort was more common in FGG during the 1st week. At 3 months localized area of repigmentation was seen in group treated by surgical blade and electrosurgery. However, no repigmentation was noticed at 3 months in diode laser group and free gingival group. Conclusion: Depigmentation of gingival hyperpigmentation using diode laser and FGG were found to be effective procedures. However, diode laser yields esthetically acceptable results along with patient satisfaction.
