The purpose of this study was to compare the response to the treatment of TMD in the two major groups of TMD disc disorders. 80 subjects with disc disorders with reduction who were treated only with behavioral modification and exercise were compared with 30 disc disorder patients as previously reported.1 Data gathered during the examination period was compared with the data after symptom were stabilized. First examination data included the TMD question and answer form, CMI test, and ordinary oral examination data. During the treatment duration, some of the data showed a significant correlation. However, no valid multivariate prediction formula for estimating treatment duration was seen. In the amount of mouth opening, two groups of TMD patients demonstrated different correlations between tenderness sites and amount of mouth opening. Tenderness of anterior temporalis at start of the treatment correlated with treatment duration and mouth opening at the end of the treatment. In patients without reduction group, more tenderness was shown. Result of this study showed that two group of TMD patients may have different responses to the TMD treatment.
