OBJECTIVE: This investigation was performed to evaluate the possibility of the removal of @entity235 gingival melanin pigmentation with the semiconductor diode (SCD) laser in vivo. SUMMARY BACKGROUND DATA: Recently, a semiconductor laser, which can ablate soft tissue, has been developed. It is already used in dentistry as well as in medicine. METHODS: The SCD laser was irradiated on the pigmented area of @entity235 gingival surface with the irradiation output of 3W. The effect of the SCD laser irradiation was evaluated at the two intervals: immediately after irradiation and at 3 weeks following irradiation. In addition, histological examination was performed before irradiation and at the same intervals from the biopsies (4 microm) of unlased and lased areas. RESULTS: The SCD laser was effective in removing melanin pigmentation. In histological examination, neither inflammatory cell nor any tissue damage was observed with @entity1710 - @entity1711 staining. At 3 weeks, there was a continuous healing process with the proliferation of squamous epithelial cells. CONCLUSIONS: SCD laser irradiation can be considered an alternative procedure for @entity2118 .
