The purpose of the present study was to evaluate the treatment effect of coronal reshaping (occlusal adjustment) by recording the sounds of teeth impact in the periodontally diseased patients with trauma from occlusion. The results are summarized as follows: 1. In evaluating the effects of coronal reshaping, the sounds of teeth impact were recorded accurately and objectively. 2. The sound of the optimal teeth impacts in 2 subjects with normal dentition was shown in monophasic (single) and compact wave, and its duration was less than 10 msec. 3. In one of 4 patients with periodontitis, the sounds of teeth impact in diphasic (double) waves before coronal reshaping was transformed into monophasic wave after coronal reshaping. The sound durations of 4 patients ranged from 11.0 msec to 19.2 msec before coronal reshaping. However, they decreased in the range of 8.3-12.2 msec 3 months after coronal reshaping in 3 patients. On the other hand, one subject showed an increase of duration to 16.8 msec.
