Outline of Final Research Achievements	The purpose of this study is to develop a sleep bruxism measuring device that is easy to use at low cost in the general clinical. In the laboratory, measurement of jaw movements that simulated the sleep bruxism, and the results ofmeasurements between the new device and general EMG were compared. As a result, it was repoted that sensitivity and specificity of the new sleep bruxism measuring device was very high, respectively.
