屠殺後24時間以内の牛前歯のエナメル質平面又は象牙質平面を注水下、#600のエメリーペーパーで唇面に平行になるように削り出した。次にその面に圧縮空気を約10秒間吹きつけて乾燥した後、そのエナメル質平面又は象牙質平面に、直径3mmの孔のあいた両面テープを貼った。次に、厚さ0.5mm直径8mmの孔の開いたパラフィンワックスを上記円孔上に同一中心となるように固定して模擬窩洞を形成した。この模擬窩洞内の上記直径3mmの孔内のエナメル質平面又は象牙質平面に、表1に示す実施例および比較例の歯科用前処理剤を歯科用マイクロブラシを使用し塗布し、10秒間処理し、10秒間歯科用水銃で水洗後、圧縮空気により10秒間乾燥した。次いで、上記直径3mmの孔内のエナメル質または象牙質の歯科用前処理剤処理面に歯質用象牙質接着材(トクヤマボンドフォース、トクヤマデンタル社製)を歯科用マイクロブラシを使用し塗布し、20秒間放置後、圧縮空気を約10秒間吹き付けて乾燥し、歯科用可視光照射器(トクソーパワーライト、トクヤマ社製)にて10秒間光照射した。さらにその上に歯科用コンポジットレジン(エステライトPクイック、トクヤマデンタル社 製)を充填し、前記歯科用可視光照射器により10秒間光照射した接着試料を得た。ビスタイトII(トクヤマデンタル社製)を接着剤として使用して、前記の接着試料のコンポジットレジン面上にステンレス棒を接着させ、接着試験片とした。接着試験片を37℃の水中に24時間浸漬した。次いで、引張り試験機(オートグラフ、島津製作所製)を用いてクロスヘッドスピード2mm/minにて引張り試験を行い、エナメル質及び象牙質への引張り接着強度を測定した。1試験当たり4本の接着試験片について引張り接着強さを測定し、その平均値を接着強度とした。
表1に示す歯科用前処理剤1〜12および比較歯科用前処理剤1〜4を使用し、(2)エナメル質および象牙質への接着試験力の測定方法に従い歯質接着強度を評価した。評価結果を表1に示した。
