Melanin Recurrence in Scalpel and LASER Gingival Depigmentation in Thin and Thick Phenotypes.

This study aimed to compare melanin pigmentation recurrence, pain perception and wound healing between laser and scalpel surgeries in thin and thick gingival phenotypes.Thirty patients (60 sites) were included in this study. They had bilateral physiologic melanin hyperpigmentation in the upper anterior segment with severe grade II melanin hyperpigmentation. The patients were divided into two groups: each with fifteen patients with severe grade II melanin pigmentation, one with thin gingiva and another with thick gingiva. Melanin depigmentation was done in one side using scalpel no. 15 and other side with diode laser.
