Abstract: Gingival melanin pigmentation (GMP) is a common clinical manifestation, characterized by black, brown or gray spots on gums. It often occurs in the attached gingiva of anterior teeth. GMP causes aesthetic problems for patients, especially those with bare-gummed smile. In addition, it may be a manifestation of some malignant tumors, genetic and systemic diseases in the oral cavity. In recent years, laser has been considered as an effective method to remove gingival melanin. This paper compares treatment time, pain, bleeding, healing speed, and recurrence of different wavelength lasers in the treatment of GMP to provide reference for clinicians.

Key words: laser, gingival pigmentation, melanin, gingival discoloration
