The color of gingiva is determined by number and size of blood vessels, thickness of epithelium, keratinization degree, and melanin pigments present in epithelium. Melanocytes, located in basal and suprabasal layers of epithelium, are the cells that produce melanin pigments which play a main role for pigmentation of gingiva. In this case series, the use of 810 nm diode laser for depigmentation of gingiva is presented. Two female patients applied with a chief complaint of "darkened gums" due to heavy smoking. In intraoral examination, diffuse melanin pigmentation was observed in both the maxilla and mandible. Under the local anesthesia, 810 nm diode laser was applied for depigmentation at 1.3 W power in continuous mode. Patients were recalled at weeks 1, 4, and 12 to evaluate the healing and recurrence rate. Both the patients had no postoperative pain or edema, and complete healing was observed at week 12. This study revealed that depigmentation with 810 nm diode laser is successful in terms of esthetics and patient comfort.
牙龈的颜色由血管的数量和大小、上皮的厚度、角化程度以及上皮中存在的黑色素决定。位于上皮基底层和基底层上方的黑素细胞是产生黑色素的细胞，黑色素对牙龈色素沉着起主要作用。在本病例系列中，介绍了使用810nm二极管激光进行牙龈色素沉着的治疗。两名女性患者因大量吸烟主诉“牙龈变黑”前来就诊。口腔检查发现，上颌和下颌均有弥漫性黑色素沉着。在局部麻醉下，以连续模式使用810nm二极管激光，功率为1.3W进行色素沉着治疗。在第1、4和12周对患者进行回访，以评估愈合情况和复发率。两名患者均无术后疼痛或水肿，在第12周观察到完全愈合。本研究表明，810nm二极管激光进行色素沉着治疗在美学和患者舒适度方面是成功的。
