title: The use of acellular dermal matrix allograft for the elimination of gingival melanin pigmentation: case presentation with 2 years of follow-up.
abstract: The most common cause of gingival pigmentation is the deposit of melanin in the basal layer of the oral epithelium. The presence of pigmentation does not constitute a pathology, and treatments including cryosurgery, Nd:YAG laser, gingival grafts, and removal of the epithelium in the pigmented area have been described in the literature. This case presentation illustrates the aesthetic treatment of bilateral gingival melanin pigmentation. The clinical results obtained using an acellular dermal matrix allograft were compared to the postoperative results of gingivoplasty in the same patient.
