三种粘结剂对牛牙抗剪粘结强度的实验分析和临床使用观察

Experimental Analysis of Tensile Bond Strength to Ox Teeth and CIinical Observations of the Applications of Threc Typcs or Adhesivcs

笔者测定ＥＢ－１粘结剂、京津粘结剂和可见光固化粘结剂对牛牙牙釉质的抗剪粘结强度，结果显示ＥＢ－１粘结剂和京津粘结剂的抗剪粘结强度均高于可见光固化粘结剂。目的在于对临床光固化复合树脂修复前牙失败的原因进行探讨。

The tensile bond strength of three different types of adhesives were compared. EB-1 enamel adhesives, JingJin enamel adhesive and Light Cured dental adhesive were applied to ox teeth enamel and to Light-Cured composit resin in experiment, The results showed that the tensile bond strength of the former two was higher than that of the rest.The purpose of this study is to explore the causes that clinical anterior restorations with Light-Cured composite resin were peeling off occasionally.
