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.

치은의 착색은 심미적 문제를 야기시킬 수 있으며 특히 gummy smile의 경우 더욱 그러하다. 이 보고는 $CO_2$ 레이저를 이용한 치은 탈색의 효용성에 대한 것이다. 멜라닌 과착색으로 인한 비심미적 치은이 주소인 두 증례를 나타내고 있다. $CO_2$ 레이저는 0.8 W, 40 Hz, 0.01로 조절하여 사용하였다. 탈색 부위는 출혈이나 술후 통증없이 치유되었다. 2주 및 4주 후 착색부위의 양호한 치유과정을 확인할 수 있었다.
