As more dentists diagnose and treat the patient with temporomandibular disorders, muscle palpation has been recognized as a valuable diagnostic method. But this method was depended on sensibility and experience of the operator.<BR>The purpose of this study was to establish the quantification of muscle palpation by new pressure pain threshold apparatus.<BR>Pressure pain threshold (PPT) was determined by the subject when a ramp force applied to the skin changed from “pressure” to “pain”.<BR>The subjects for the experiments were 90 normal males, 100 normal females and one patient with temporomandibular disorders.<BR>Total of 12 sites, anterior temporal M., posterior temporal M., superficial portion of masseter M. and deep portion of masseter M., were measured.<BR>The results obtained were as follows:<BR>1. The females showed lower PPT than the males.<BR>2. No difference of PPT between right and left sides was recognized in normal subject, but the significant difference in the patient.<BR>3. PPT of the normal subjects were significantly higher in the posterior temporal M. than the other sites and lower in the superficial portion of masseter M. than the other sites.
