 note = {application/pdf, Irradiation by a CO² laser was studied in seven patients aged 23 to 29 years with gingival melanin pigmentation. The CO² laser irradiated the surface of the pigmented gingiva under the conditions of diameter of the probe tip 0.8mm, output 3W and local anesthesia using spray of the 8% Lidocaine. Immediately after irradiation, the gingiva surface showed opaque dark white colors and carbonization appeared. After several days, the pigmentation of the gingiva disappeared in all cases without hemorrhage and epidermal detachment. We conclude that CO² laser irradiation is a useful and safe technique for the removal of gingival pigmentation.},
