Gingival Depigmentation With Diode and Er,Cr:YSGG Laser: A Split-mouth Trial
Sponsor: Can Tho University of Medicine and Pharmacy
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.
