Research progress in the treatment of gingival melanin pigmentation.

Abstract

Abstract:

Abstract：Melanocytes and keratinocytes are located primarily in the basal and suprabasal cell layers of the epithelium. Gingival melanin pigmentation（GMP）occurs when these cells deposit excessive amounts of melanin. Although GMP does not represent a medical problem，but GMP may result in complaints about poor esthetics，especially among individuals with excessive gingival display while smiling or talking.

Key words: gingival melanin pigmentation, laser, melanin

摘要：

牙龈黑色素沉着（gingival melanin pigmentation，GMP）是由于黑色素母细胞分泌的黑色素颗粒沉积在牙龈黏膜的基底层及固有层所导致。虽然在多数情况下它不是病理性症状，但却给许多患者，尤其是露龈笑的患者造成美观上的困扰。本文对GMP的治疗方法及研究进展做一综述。
