Depigmentation Using Scalpel and Diode Laser: A Split Mouth Case Report

Abstract Gingival hyperpigmentation is a hereditary condition that, while not harmful, can affect smile aesthetics and cause psychological distress. Gingival depigmentation is a cosmetic periodontal procedure used to reduce this pigmentation. Techniques include scalpels, lasers, cryosurgery, electrosurgery, and chemical methods, with lasers and cryosurgery showing better results and lower recurrence. Treatment choice depends on factors like skin tone, pigmentation level, lip line, and patient expectations. This case report compares scalpel and diode laser treatments in a 24-year-old female using a split-mouth design. The scalpel side healed well, while the laser side offered a bloodless field and quicker recovery. No pain, scarring, or repigmentation was observed, and the patient was pleased with the outcome.
