Abstract
Gingival hyperpigmentation may cause esthetic problems, especially in patients with a gummy smile. This report presents the use of the $CO_2$ laser for gingival depigmentation. Two cases presented with the same chief complaint of unesthetic gingiva caused by melanin hyperpigmentation. The $CO_2$ laser was setted at 0.8 watt, 40Hz, 0.01sec. The procedure were performed with non-contact mode in all pigmented areas. Ablation of the gingival hyperpigmentation areas were accomplished without any bleeding complications or postoperative pain. After 2 weeks and 4 weeks later, healing is completed and hyperpigmented gingiva appeared pink and firm.
