An aesthetically pleasing smile is determined not only by the shape, position and color of teeth but also by the color, contour and health of the gingival tissues [1]. Since gingival color is currently considered an essential component of an attractive smile, a higher demand for gingival depigmentation has been observed, especially on the labial aspect of anterior teeth [2,3]. The purpose of this paper is to provide an overview of gingival melanin hyperpigmentation and its causes, its clinical presentation, indices and different depigmentation treatment modalities.
