Comparison of Er-YAG Laser, Air Polishing, and Surgical Excision for Gingival Hyperpigmentation
Sponsor: Ondokuz Mayıs University
Summary
This randomized controlled clinical trial aimed to compare the effectiveness of different treatment approaches for physiologic gingival hyperpigmentation. Participants with gingival melanin pigmentation were randomly assigned to one of four treatment groups: Er:YAG laser treatment, air polishing with erythritol powder, air polishing with sodium bicarbonate powder, or conventional surgical excision. Clinical outcomes were evaluated using pigmentation index scores, digital image analysis, and color measurements at baseline and follow-up visits. Patient-centered outcomes, including postoperative discomfort and satisfaction, were also assessed. The study sought to determine whether air polishing techniques could provide clinical outcomes comparable to conventional treatment approaches while improving patient comfort and satisfaction.

Interventions
Er:YAG Laser Therapy
Gingival depigmentation was performed using Er:YAG laser therapy to remove physiologic gingival melanin pigmentation. The procedure was applied according to the manufacturer's recommended clinical protocol for soft tissue ablation.
Air Polishing with Erythritol Powder
Gingival depigmentation was performed using an air polishing system with erythritol powder to remove physiologic gingival melanin pigmentation. The procedure was carried out by applying pressurized air and powder particles to the pigmented gingival surface according to the treatment protocol.
Air Polishing with Sodium Bicarbonate Powder
Gingival depigmentation was performed using an air polishing system with sodium bicarbonate powder to remove physiologic gingival melanin pigmentation. The procedure was carried out by applying pressurized air and powder particles to the pigmented gingival surface according to the treatment protocol.
Conventional Surgical Excision
Gingival depigmentation was performed using a conventional surgical excision technique for the removal of physiologic gingival melanin pigmentation. The procedure involved surgical removal of the pigmented gingival epithelium using conventional periodontal surgical instruments according to standard clinical practice.
