The harmony of smile is attributable to the shape, colour, and position of the teeth, but also to the level and color of the gingival tissues. Gingival pigmentation occurs in all races of man and it varies from one race to another. It results from melanin granules which are produced by melanoblasts. An excessive gingival pigmentation frequently poses an aesthetic problem, especially in patients with gummy smiles. Various procedures have been proposed for removal of the gingival pigmentation and to restore esthetics. These techniques include gingivectomy, free gingival autografts, surgical depigmentation, electrosurgery, cryotherapy, use of rotary instruments, chemical agents and lasers. The objective of this article is to report a case of the gingival depigmentation technique using a 980 nm diode laser in a young patient treated in the oral surgery department of the dental consultation and treatment center of Casablanca and to shed light on the effectiveness of this technique which has produced good results and led to patient satisfaction.
