RESUMO
Introduction: Gingival depigmentation is a surgical procedure done to eliminate or reduce gingival hyperpigmentation. Various techniques are employed such as scalpel de-epithelization, gingivectomy, electrosurgery, use of chemical agents, cryosurgery, and lasers. The present study was conducted to assess the efficacy of laser and electrosurgical procedure in reducing gingival pigmentation in terms of pain, wound healing, and recurrence of melanin pigmentation. Methodology: A prospective study was conducted on 40 subjects affected by melanin pigmentation. Group I patients were treated with electrosurgery and Group II patients with diode laser procedure. Evaluation for pain was done intraoperatively, 24 hours and 7 days using VAS. Wound healing and recurrence of pigmentation was assessed at one month and three months. Results: No significant difference was noted between the two groups for pain assessment at 7 days with P > 0.001. Both electrosurgery and laser group showed significant differences between intraoperative time period to 24 hours and 24 hours to 7 days at P < 0.001 for pain. Conclusion: Esthetic demands necessitate cosmetic gingival depigmentation procedure. Laser diode photoablation proves to be an effective and reliable technique in achieving the same.
