Description
顎模型の上顎第一大臼歯部分に疑似プラークを付着させ、該顎模型をブラッシングシミュレーション装置に取り付け、上顎第一大臼歯に歯ブラシ植毛部の一方の端が当たるように当て、植毛部が第一大臼歯を覆うように歯ブラシを設置する。横方向のストロークを20mmとして荷重150gをかけて3秒間ブラッシングを行い、疑似プラークの面積を画像解析装置にて、各部位ごとに計測算出し、疑似プラークを付着させた面積に対する疑似プラークが除去された面積の割合をプラーク除去率とした。
歯ブラシを37℃の温水に浸漬し、荷重300gをかけて、1万回往復運動させた場合、(A)初期状態の歯ブラシ短軸方向の植毛部幅(植毛されているブラシ毛の先端における幅)と、(B)1万回往復運動後の毛の開いた状態の歯ブラシ短軸方向の植毛部幅とを測定し、下式により耐久性指標を算定し、100%以上150%未満を「○」、150以上200%未満を「△」、200%以上は「×」とした。
耐久性指標(%)=[(B)/(A)]×100
実施例1と同様にしてプラーク除去率(%)を求め、70%以上を「○」、30%以上70%未満を「△」、30%未満を「×」とした。

Claims (1)
- 先端部にテーパー部が形成された合成樹脂製フィラメントからなるブラシ毛が植毛台に植設された歯ブラシにおいて、前記ブラシ毛のテーパー部の長さaが前記フィラメントの最大径部の直径bの10〜15倍であり、前記フィラメントの最大径部の直径bが0.18mm以下であり、かつ前記テーパー部が、フィラメント最大径部から先端に向かって、直線状又はフィラメント軸芯側に凹んだ曲線状に先細になっており、
前記ブラシ毛の先端から前記テーパー部の長さaの1/2の部位の直径dがフィラメント最大径部の直径bの50%以上であり、
前記テーパー部が機械加工により形成されたものであり、前記テーパー部の先端部分においては、前記最大径部から続く先細形状の傾斜が次第に緩やかになり、先丸加工に近い形状で、前記ブラシ毛の先端から0.1mmの部位の直径cがフィラメント最大径部の直径bの20〜60%であり、
前記合成樹脂製フィラメントがポリトリメチレンテレフタレートとポリブチレンテレフタレートとを溶融混合した樹脂からなり、ポリトリメチレンテレフタレートの混合率が50重量%以上である、
ことを特徴とする歯ブラシ。
