Description
[試験1:歯間への挿入性評価]
誘導部16が屈曲点を1つのみ有する歯間清掃具(歯間ブラシ)を使用し、挿入角度αをパラメータとして、奥歯の歯間への清掃部20の挿入し易さを評価した。屈曲点の位置は、先端部12から20mmとした。また、把持部14の長さは30mmとした。
表1の結果から、挿入角度αが120〜145度の範囲(実施例1〜6)で、評点は7.5(やや良好)以上となり、好ましい範囲であると判断できる。また、挿入角度αが130〜140度の範囲で評点は8.5以上であり、より好ましい範囲であると判断できる。
試験1の実施例1〜6(誘導部における屈曲点が1つ)及び実施例7〜12(誘導部における屈曲点が2つ)の各歯間清掃具を使用し、奥歯の歯間に清掃部20を挿入した後、把持部14を前後方向(図3の矢示B方向)に動かして、清掃時の操作性を評価した。試験1と同様に、15名の被験者に対して、0点(操作が極めて困難)から10点(操作が極めて容易)まで0.5点刻みで評価してもらい、得られた点数を平均し、小数点第二位を四捨五入した値を評点とした。この結果を表3及び表4に示す。
表4における改善率は、表3と表4との間で挿入角度αが同一のもの同士を比較した結果である。表4の結果を表3の結果と対比すると、全ての挿入角度αに対して評点は向上しており(すなわち、改善率が100%より高い)、誘導部16における屈曲点の数を増やすことにより、清掃時の操作性がより向上していると判断できる。
