The influence of mechanical stimulation on the human body is extremely important. We hypothesized that if tooth impact is propagated to other sites of the body, this impact will have some effect on those sites as well. The purpose of this study was to investigate the extent to which tooth impact was propagated in the head and neck. It was found that the waves recorded on the upper canine are divided into a high frequency component and a low frequency component at a border of approximately 7 kHz. The amplitude of the impulse wave was 80·813 g for the low frequency component, and 177·839 g for the high frequency component. In terms of propagated vibration from the canine, the amplitude of the low frequency component was larger than that of the high frequency component, and greatest at the chin, followed in descending order by the zygomatic bone, forehead and vertebra prominens. For both frequency components, the amplitude of the propagated vibrations was small compared with the impulse waves. These results provide a basis for future analysis of the influence of such impact on cell response.
