前文已报导了树脂类充填料与酸蚀牙釉质、牙本质粘结的离体研究结果。但它毕竟有别于活体研究,尤其是牙本质,活体与离体是有很大差异的,而活体与离体牙釉质是否相似呢,均有待实验观察来证实。在临床上树脂类充填料与活体牙粘结实用价值更大,为此,本研究仍用扫描电子显微镜(SEM)来观察单一和复合树脂(光敏与自凝固化体系)渗入酸蚀活体牙牙釉质、牙本质的情况,以便与离体研究作对照,并为临床应用提供科学依据。 The foregoing has reported the results of in vitro studies on the adhesion of resin fillers to etched enamel and dentin. However, after all, it is different from living research, especially dentin, living and in vitro are very different, and living and isolated enamel are similar, are subject to experimental observation to confirm. In clinical practice, resin-based filling material has more practical value in bonding with living teeth. Therefore, SEM and SEM were used to observe the infiltration of single and composite resin (photosensitive and self-curing system) , Dentin situation in order to contrast with the in vitro studies and provide a scientific basis for clinical application.
