説明
The purpose of this study was to quantitatively clarify the stress distribution on oral tissue when toothbrushing force is transmitted through the bristles of a toothbrush.<BR>We analysed dynamically two cases of toothbrush movement by the non-linear finite element method and the following results were obtained;<BR>1. Toothbrushing movement in a gingiva model.<BR>Two kinds of toothbrush, round end bristles and extremely tapered end bristles were each pressed 1 mm toward the periodontal tissue and set in motion horizontally with 6 mm reciprocation.<BR>The result of analysis showed that the toothbrush with round end bristles generated a stress of 300-600g/cm2 on the gingiva. On the other hand, the 130-200g/cm2 from the toothbrush with extremely tapered end bristeles, was considerably lower than that of the former.<BR>2. Entry of the bristle end into the periodontal pocket model.<BR>We compared ease of entry into the periodontal pocket of two kinds of bristles, extremely tapered end bristles and lightly tapered end bristles.<BR>Two bristles were tried for entrance into the periodontal pocket.<BR>The result of analysis was that extremely tapered end bristles were easy to insert smoothly into the periodontal pocket, but lightly tapered end bristles were not.<BR>The stress of lightly tapered end bristles on periodontal tissue was 6-7 times higher than that of extremely tapered end bristles.<BR>In the case of the entry angle being changed, ease of entry was nearly equal to that of extremely tapered end bristles.
