Classification of one-step adhesive systems based by the ability to remove clinically produced smear-layer and evaluation of their short- and long-term bonding effectiveness

本研究的目的是根据去除(溶解)临床产生的涂抹层的能力对许多商业上可用的一步粘接系统进行分类，并评估它们的短期和长期粘接效果。在本项目结果的限制内，得出结论：作为本研究的目的之一的分类很难通过去除临床产生的涂抹层的能力来实现，研究还表明，在使用一步粘接系统的情况下，选择毛刺或切割点来切割牙齿基材是非常重要的，因为一些粘接系统在粘接到用规则磨料金刚石毛刺产生的牙本质表面时，在100,000倍的热循环应力后会降低粘结强度。

The aim of this study was to classify a lot of commercially available one-step adhesive systems according to the ability to remove (dissolve) clinically produced smear-layer, and to evaluate their short- and long-term bonding effectiveness.Within the limit of the results of the present project, it is concluded that their classification as one of the aims of this study was very difficult to be perfomed by the ability to remove clinically produced smear-layer, and also indicated that the selection of burs or points to cut tooth substrates is thought to be very important in case of the application of one-step adhesive systems because some adhesive systems decrease the bond strength after 100,000 times thermo-cycle stress when bonded to the dentin surfaces produced with a regular-grit diamond bur.
