Abstract

Gingival melanin pigmentation is a frequent aesthetic concern, resulting from increased melanin production by melanocytes located in the basal and suprabasal layers of the oral epithelium. Its etiology ranges from physiological pigmentation to systemic pathologies. Gingival depigmentation aims to improve smile aesthetics using various surgical techniques, among which the Er:YAG laser is recognized for its precision and minimal thermal damage.

We report the case of a 34-year-old female patient with diffuse melanin hyperpigmentation in the anterior maxillary gingiva, treated with an Er:YAG laser. The procedure led to effective pigment removal, favorable wound healing, and high patient satisfaction. Clinical follow-up showed minimal postoperative discomfort, complete re-epithelialization within two weeks, and no gingival recession. However, slight residual pigmentation was noted.

This case highlights the effectiveness of the Er:YAG laser in gingival depigmentation, offering advantages in terms of patient comfort, healing quality, and aesthetic outcomes. Nevertheless, limitations include suboptimal hemostasis and a relatively high risk of repigmentation.

Er:YAG激光治疗牙龈色素沉着的微创美学治疗

牙龈黑色素沉着是一个常见的美学问题，是由位于口腔上皮基底和上基底层的黑色素细胞产生的黑色素增加引起的。其病因范围从生理性色素沉着到全身性病理。牙龈脱色旨在通过各种手术技术改善微笑美学，其中Er:YAG激光以其精度和最小的热损伤而得到认可。我们报告一例34岁女性上颌前龈弥漫性黑色素色素沉着，用Er:YAG激光治疗。该手术有效去除色素，伤口愈合良好，患者满意度高。临床随访显示术后不适最小，两周内完全上皮化，无牙龈萎缩。然而，注意到轻微的残留色素沉着。本病例强调了Er:YAG激光治疗牙龈色素沉着的有效性，在患者舒适度、愈合质量和美学结果方面提供了优势。然而，局限性包括不理想的止血和相对较高的再色素沉着风险。
