Many studies were achieved on the application of Er: YAG laser to periodontal disease. We irradiated Er: YAG laser with the energies of 30mJ at 10 pulse per second (pps) with enough to water and air into the periodontal pockets and measured the changes of temperature of the laser irradiated tissues and followed up the four chronic periodontitis patients. The temperature of both irradiated and non-irradiated was measured before, on and recovery. The temperature of chronic lesions which was lower than the neighboring sound lesions before the irradiation, raised after the irradiation. After recovery temperature of irradiated lesions was same as sound lesions. It was suggested that the temperature of the periodontal lesions raises as recovery.
