Abstract

The aim of this study was to investigate the effect of 2-hydroxyethyl methacrylate (HEMA) in an Al2Ox3/glycine solution used as primer for dentin bonding in combination with an experimental BISGMA-HEMA-based adhesive resin. With various amounts of HEMA in the Al2Ox3/glycine solution, a shear bond test showed a maximum strength at 50 wt% of HEMA. In this case, scanning electron microscopy examination showed a HEMA-infiltrated surface layer of the dentin along the interface between dentin and the adhesive resin. It is suggested that HEMA in Al2Ox3/glycine solutions may facilitate penetration of HEMA into etched or primed dentin.

摘要

本研究的目的是研究甲基丙烯酸2-羟乙酯（HEMA）在Al2Ox3/甘氨酸溶液中作为牙本质粘结底漆与一种实验性双酚A缩水甘油醚甲基丙烯酸羟乙酯（BISGMA-HEMA）基粘结树脂联合使用时的效果。在Al2Ox3/甘氨酸溶液中加入不同量的HEMA后，剪切粘结试验表明，当HEMA含量为50 wt%时粘结强度最大。在这种情况下，扫描电子显微镜检查显示，沿着牙本质与粘结树脂之间的界面，有一层HEMA渗透到牙本质表面层。有人认为，Al2Ox3/甘氨酸溶液中的HEMA可能有助于HEMA渗透到酸蚀或涂底漆的牙本质中。
