The effect of 4-[2-(methacryloyloxy)ethoxycarbonyl]phthalic acid (4-MET) in self-curing acrylic resin initiated by BPO-amine on the bond strength to etched enamel was studied. Scanning electron microscopic (SEM) observations of resin-enamel interfaces were carried out to elucidate the bonding mechanism and the effect of 4-MET on the adhesion. 4-MET, which has both hydrophilic and hydrophobic groups, increased the bond strength of self-curing acrylic resin to etched enamel and improved the bonding stability. SEM pictures strongly suggested that 4-MET promoted interpenetration of monomers into enamel prism peripheries and their polymerization therein resulted in excellent adhesion to etched enamel.
研究了4-[2-(甲基丙烯酰氧基)乙氧基羰基]邻苯二甲酸(4-MET)在BPO-胺引发的自凝丙烯酸树脂中对蚀刻牙釉质粘结强度的影响。通过扫描电子显微镜(SEM)观察树脂-牙釉质界面，以阐明粘结机制以及4-MET对粘结的影响。具有亲水性和疏水性基团的4-MET提高了自凝丙烯酸树脂与蚀刻牙釉质的粘结强度，并改善了粘结稳定性。SEM照片有力地表明，4-MET促进了单体向牙釉质棱柱周边的互穿，并且它们在其中的聚合导致了对蚀刻牙釉质的优异粘结。
