Abstract

The aim of this study is to elucidate influence of environmental factors on development of the stomatognathic system through occlusal analyses. The parameters of the occlusion of twenty-one Japanese grown on a soft dietary pattern and same number of Mongolians grown on a natural texture dietary pattern were analysed by the pressure sensitive film (Dental Prescale, GC Co. Tokyo, Japan) and the black silicone (Bite Checker, GC Co. Tokyo, Japan). There were significantly differences in the mean occlusal contact area and occlusal pressure, although not difference in the mean occlusal force between the Japanese and Mongolian groups. These finding indicated that the environmental factors could influence several parameters of the occlusion. An analysis of the occlusal contact area is important for the objective evaluation of the prosthodontic treatment according to individual characteristics of people.
