Treatment of melanotic spots in the gingiva by argon laser

Dark colored areas, ranging from light blue to black, often occur in the gingiva as a result of the abnormal deposition of melanin. These can develop at any age, creating an unesthetic appearance. The effective elimination of these melanotic areas can be accomplished by treatment with monoline 514 nm green light (1.5 W, 300 milliseconds, 0.5-mm spot size) produced by an argon laser. Restoration of the mucosa is optimal, giving excellent esthetic results.
