Abstract
Description
(1) ヘッド部に、毛の充填密度が60%未満である毛束が植設されている無平線の歯ブラシ。ここに「毛の充填密度」とは、毛束が植設されている植毛穴口部面積に対する当該口部の位置における当該毛束を構成している毛の総断面積の比率をいう。
(Eはヤング率、ωは毛の直径、Lは毛丈(植毛面からの突出長さ)である。)
それぞれ、図4(a),(b)に示す歯ブラシ1Aを作成した。いずれも同じ構造、寸法であり、植毛穴21についても同じ配置、寸法とした。具体的には、図4に示すように、植毛穴21を縦横3列ずつ合計9つ設け、各植毛穴21は口部21aが円形で内径1.6mmの貫通穴とした。
各実施例、比較例について、歯ブラシのブラッシング圧及び移動速度を一定に保ちながら、固定した顎模型(D15−500H、ニッシン社、京都)の歯をブラッシングできるように設計されたブラッシングシミュレータを用いた。顎模型の特定の歯(上顎第一大臼歯)を取り外し、その歯間面(隣接する上顎第二小臼歯に臨む面)にプラークの代替として咬合チェック用スプレー・オクルード(パスカル社、USA)の着色粉末を塗布して顎模型に戻し、ブラッシングを行った。
