Description

The purpose of this study was to investigate the relationship between the stomatognathic system and physical exercise. Intensive physical exercise is often accompanied by a clenching of the jaws and the teeth. In the present study, frequency of clenching during physical exertion was investigated in one hundred young adults. Measurement of back strength was used as physical exertion. Clenching during physical exertion was evaluated using PhotoocclusionTM(rocky mountain orthodontics).<BR>The following results were obtained<BR>1. Centric clenching was shown in fifty eight percent of the subjects during physical exertion.<BR>2. Eccentric tooth contacts were shown in eleven percent of the subjects, but thirty one percent did not show any occlusal contacts during physical exertion.<BR>3. Although there were individual variation, physical exertion had some effect to stomatognathic system.<BR>Those results suggest that the stomatognathic system may play a significant role in the physical exertion.
