Gingival Depigmentation Using Surgical Excision Technique: A Histopathological Case Series
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 10
Abstract
Melanin pigmentation of the gingiva occurs in all races. Melanin, a brown pigment, is the most common natural pigment contributing to endogenous pigmentation of gingiva and the gingiva is the most frequently pigmented intra oral site. According to the early prevalence studies the distribution of oral pigmentation in black individuals is as follows gingiva 60% hard palate, 61% mucous membrane,22% and tongue 15%. Gingival pigmentation occurs as a diffuse,deep-purplish discoloration or as irregularly shaped brown and light brown patches. It may appear in the gingiva as early as 3 hours after birth and often is the only evidence of pigmentation. Melanin pigmentation is the result of melanin granules produced by melanoblastsinterwined between epithelial cells at the basal layer of gingival epithelium. This case series presents a simple surgical technique of De-epithelization which has been successfully used to treat gingival hyperpigmentation caused by excessive melanin deposition and highlights the relevance of an esthetically pleasing smile specially in smile conscious individuals.
