Background: Pigmentation of the gingiva is a negative factor in an otherwise acceptable "smile window." Recently, laser techniques have gained popularity for depigmentation and seem to be the most reliable and satisfactory procedures. To our knowledge, this case series is unique and is the first reporting comparison of scalpel techniques and lasers in the literature. Materials and methods: The study included 20 patients who presented with a chief complaint of "black gums" and requested cosmetic therapy. Patients in group A were related using a diode laser. Procedure started with the application of topical anesthesia. Patients in group B were treated using scalpel techniques. Patients were followed for 3, 6, and 12 moths. Gingival depigmentation was assessed using a new index system, gingival pigmentation index, on the day of first depigmentation and at the end of 12 months. Results: The mean age of the subjects in Group A was 25.76+/-1.34 years. And the mean age of subjects in Group B was 25.22+/-2.61 years. On first postoperative day, it reduced to 0 in both the groups. On applying student t test, there was no significant difference between both the groups. Conclusion: During the 12-month follow-up, the depigmentation achieved using both the techniques was found equivalent and satisfactory Key words: Cosmetic, depigmentation, Gingival, laser.
