Abstract

歯問ブラシの毛丈, ワイヤー径, 刷掃回数, 歯間ブラシ圧の因子がプラーク除去効果に及ぼす影響を検討するため, 9種類の歯間ブラシを作製し, 模型上で隣接面の人工プラーク除去量を測定し比較検討を行った。その結果,<BR>1) 歯間ブラシ圧が高くなるに従いプラーク除去量が増加し, 30, 40gにおいて有意に高かった。歯間ブラシ圧が40g以上になると, プラーク除去量が有意に低かった。<BR>2) 毛丈5mmの歯間ブラシが, 3mm, 7mmに比較しプラーク除去量が有意に高かった。<BR>3) ワイヤー径0.25mmの歯間ブラシに比較し, ワイヤー径0.30 mm, 0.35 mmの歯間ブラシのプラーク除去量が有意に高かった。<BR>4) 歯間ブラシの刷掃回数が増えるごとにプラーク除去量が有意に増加した。

The present study was undertaken to examine the effects of the following interdental brush factors on plaque removal : (1) the length of the bristles on the brush, (2) the diameter of the metal rod in the center of the interdental brush (3) the frequency of brushing, and (4) brushing pressure. Nine different types of interdental brushes were prepared, and their effectiveness in removing artificial plaque from the proximal surfaces of model teeth was examined. The following results were obtained.<BR>1. With the addition of weight to the interdental brush pressure, plaque removal values increased. At pressures of 30 g and 40 g statistically significant increases in values were seen. In the pressure over 40 g group, plaque removal values were significantly decreased.<BR>2. In the 5 mm bristle length group, plaque removal values were significantly increased as compared with the 3 mm and 7 mm groups.<BR>3 . In the 0.30 mm and 0.35 mm wire diameter groups, plaque removal values were significantly increased as compared with the 0.25 mm group.<BR>4. As the brushing frequency increased, plaque removal values increased significantly.
