Destruction of periodontal tissues become severe when periodontal inflammation co-exists with excessive occlusal force. Of the types of occlusal factors, bruxism considering the strength, time interval, and working direction, is considered to be the most influ -encing on periodontal tissues .<BR>In this study, the nocturnal bruxism was recorded by utilyzing the Grinding Monitering System (GMS) developed by Uraguchi. The recorded sound was analyzed by the FFT analyzer . The periodontal condition of the 6 subjects on the time of initiating the experiment was almost healthy . The equipment, tape and questionaire was taken home. On awakening, the sleeping and awakening time, and the answers to the questionaire was recorded. After one month, the tape was recovered, and the time-axis frequency and the frequency components were considered.<BR>As a result, bruxism which lacks objective parameters and is difficult to classify according to audible sound, was found to be capable to be classified from the distinctive features of the time-axis frequency and frequency components. Moreover, it was found that bruxism involves a certain personal rythm.
