Recently, sedative and antiphlogistic treatment is conducted with low energy laser irradiation. The purpose of the this study was to evaluate the effectiveness to decrease of pain just after irradiation by a GaAlAs semiconductor laser. The irradiation apparatus was SEMI LASER NANOX (LX-800 : G-C. Co.) with the following features : a wave lengh of (around) 780nm : the laser energy, 30mW ; exposure time, SOsec to ISOsec/ per treatment. Diagnosis of pre-and post-operative sensitivity were classified into the following four grades : Grade 0 no pain. Grade I mild pain. Grade II strong but tolerable pain. Grade III intolerable pain (simultaneous with stimulation). The results were as follows: 1. In the hypersensitivity of dentin, the treatment was not effective with 2 cases of grade III, but with all of grade I , II (35 cases) the pain decreased just after irradiation. 2 . It was effective in all cases with pain like periodontitis after root canal filling and pain after extraction of teeth. 3 . It was effective in all cases with gingivitis, stomatitis, and gingival ulcers after infilttation anesthesia etc..
