本文研究了用甲基丙烯酸羟乙酯（HEMA）和戊二醛混合溶液预处理牙本质后，修复树脂与牙本质之间的粘接强度。有人建议，该混合物的作用是通过形成一个化学键的HEMA分子的胶原蛋白-戊二醛反应复合物。随后施加的树脂将与胶原连接的甲基丙烯酸酯基团共交联。对不同HEMA和戊二醛混合物结果的统计分析表明，粘合强度高度依赖于HEMA浓度，最大值为35%，当大于3%时，几乎与戊二醛浓度无关。最高平均粘结强度约为1.8 kg/mm 2，该尺寸量级的粘结强度可能对临床使用有吸引力。
We investigated the bond strength between restorative resin and dentin pre-treated with mixtures of HEMA and glutaraldehyde. It is suggested that the mixture acts by forming a chemical bond of HEMA molecules to a collagen-glutaraldehyde reaction complex. Subsequently applied resin will then co-polymerize with the collagen-linked methacrylate groups. Statistical analysis of the results from varying mixtures of HEMA and glutaraldehyde revealed that the bond strength was highly dependent on the HEMA concentration, with a maximum at 35%, and nearly independent of the glutaraldehyde concentration when greater than 3%. The highest mean bond strength was about 1.8 kg/mm2, and bond strength of this order of size may be attractive for clinical use.
