Abstract
Oral melanin pigmentation is common in some races and ethnic groups. The gingivae are the most frequently pigmented intra-oral tissues. Melanin pigmentation is the result of melanin granules, produced by melanoblasts intertwined between epithelial cells at the basal layer of the epithelium. We present one case of melanin pigmentation of the gingiva of 26-year old female. Melanin depigmentation method is applying a 90% phenol solution to deepithelize pigmented areas, gingivectomy, epithelial abrasion, bone denudation, and split thickess flap. We chose epithelial abrasion using round diamond bur. The patient satisfies the result and have almost no pain and discomfort. But repigmentation potential must be noticed to patient.
