29 experimental Class V restorations using a chemically cured composite resin were inserted in human third molars in cavities which after acid-etching had been treated with absolute ethanol. After extraction and demineralization of the teeth, the fillings were examined in SEM concerning their enamel and dentin replica patterns on the inner cavity-faced surface. The SEM findings were compared with previous findings concerning the replica patterns on fillings from acid-etched cavities and from cavities which after acid-etching had been treated with an ethanol solution of the surface active comonomer N-phenylglycine-glycidyl methacrylate (NPG-GMA). It was found that cavity treatment with absolute ethanol further improved the increased enamel replica patterns obtained with the NPG-GMA/ethanol comonomer solution while only the NPG-GMA/ethanol treatment improved the dentin replica patterns. Based on these results the effect of each of the two main components in the comonomer solution on replica patterns on resin restorations could be disclosed.
使用化学固化复合树脂的29个实验性V类修复体被植入人类第三磨牙经酸蚀后用无水乙醇处理过的窝洞中。牙齿拔除并脱矿后,在扫描电子显微镜下检查填充物内腔面的釉质和牙本质复制模式。将扫描电子显微镜的结果与先前关于酸蚀窝洞以及酸蚀后用表面活性共聚单体N-苯基甘氨酸-甲基丙烯酸缩水甘油酯(NPG-GMA)乙醇溶液处理的窝洞填充物复制模式的研究结果进行比较。结果发现,用无水乙醇处理窝洞进一步改善了使用NPG-GMA/乙醇共聚单体溶液所获得的釉质复制模式的增加,而只有NPG-GMA/乙醇处理改善了牙本质复制模式。基于这些结果,可以揭示共聚单体溶液中两种主要成分对树脂修复体复制模式的影响。
