A study is presented of occlusosonograms obtained from healthy subjects and patients with periodontal diseases and gnathic problems. Gnathosonic examinations were carried out by means of a set of equipment whose basic elements were two piezoceramic transducers mounted on a specially made holder and an IBM PC with an ADC card. The evaluation of occlusosonograms was by means of mathematical analysis of the frequency pattern. In pathological stages, the occlusosonograms exhibit more high frequency components. In the case of healthy subjects, the recorded signal took the form of a strong impact of low frequencies and its subsequent exponential decay.
