Comparative evaluation of depigmentation techniques in split-mouth design with electrocautery and laser.

Excessive gingival pigmentation is a major esthetic concern for many people. Melanin pigmentation is known to be caused by melanin granules within the gingival epithelium. Smile is determined not only by the shape, the position, and the color of the teeth, but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile. It is not a medical problem, but it feels unesthetic for the patient and particularly in patients having a very high lip/smile line. Depigmentation is not a clinical indication but a treatment of choice where esthetics is a concern and is desired by the patient. For depigmentation of gingival, different treatment modalities have been reported such as bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery, and laser. The present case series describes two simple and effective surgical depigmentation techniques treated with diode laser and electrosurgery.
