Comparison of Diode and Er,Cr:YSGG Lasers in Gingival Depigmentation: a Split-mouth Randomized Trial
In Brief
A clinical study evaluating Er,Cr:YSGG laser and Diode laser for Gingival Hyperpigmentation. Completed, enrolled 38 participants across 2 sites.
Detailed Summary
Gingival hyperpigmentation is a common physiological condition caused by excessive melanin deposition in oral mucosa, negatively affecting smile esthetics. Laser therapy has become an effective treatment option due to advantages such as minimal bleeding, reduced postoperative discomfort, and faster healing. This clinical study aims to evaluate clinical characteristics of gingival pigmentation and compare treatment outcomes between diode laser and Er,Cr:YSGG laser techniques. Outcomes include pigmentation reduction, postoperative pain, wound healing, bleeding, patient satisfaction, and recurrence rate.
