| 要約: | A beautiful smile definitely enhances the personality of an individual and reveals self-confidence. The harmony of the smile is determined not only by the shape, position, and color of the teeth but also by the gingival tissues. Gingival pigmentation results from melanin granules which are produced by melanoblasts. Although melanin pigmentation of the gingiva is a completely benign condition and does not pose any medical problem, complaints of "black gums" are common particularly in patients having a very high smile line. The different treatment modalities that have been reported for depigmentation are bur abrasion, partial thickness flap, cryotherapy, electrosurgery, and lasers. In this paper we have compared the results of electrosurgery and scalpel technique, i.e., partial thickness flap.
