Comparison between Diode Laser and abrasive bur techniques of gingival melanin depigmentation

Abstract

Pigmentation of the gingiva plays a negative role in an otherwise acceptable ―smile window‖. In the present world, people are more concerned about their aesthetics. Several techniques have been employed such as scalpel surgery, electrosurgery, cryosurgery, chemical agents, abrasion and LASER method for the removal of melanin hyperpigmentation. Objectives :The present study is aimed at comparing the efficacy of Diode LASER and soft tissue Bur trimmer for gingival depigmentation. Methods: Acase report study was conducted for one patient with gingival pigmentation. Dummet Oral Pigmentation Index (DOPI), Gingival Pigmentation Index (GPI) for pigmentation, bleeding factor, wound healing factor, gingival colour and visual analogue scale (VAS) score for pain were evaluated for Maxillary and mandibular arches at baseline, 7th day. Results: The patient treated with diode laser experience less intra and post operative pain ,less local anathesia were used ,no bleeding and complete healing until 7th day, As for bur trimmer mandibular attached gingiva more local anesthesia was used, more postoperative pain ,which disappear gradually until 7th day, more intraoperative bleeding and incomplete wound healing at 7th day.
