已经开发出单步自蚀刻粘合剂系统以简化和缩短粘合程序。随着这些简化系统的普及，其可靠性已成为关注的焦点。本研究的目的是确定粘结剂的应用方法对釉质粘结强度的影响。使用两种商业单步自蚀刻粘合剂系统，Clearfil tri-S Bond和G-Bond。将牛下颌切牙安装在自固化树脂中，并将面部釉质表面在600粒度的SiC纸上湿磨。粘合剂仅在不搅拌的情况下施加（非活性的）或通过刷子搅拌（活性的），并且树脂复合物被冷凝到釉质表面上的模具中并被光活化。每个试验组10个样本在37 ℃的水中储存24 h，然后以1.0 mm/min的十字头速度进行剪切试验。使用双因素方差分析，然后进行Tukey HSD检验。活性施用的粘结强度高于非活性施用。发现两种粘合剂系统存在显著差异。从这项研究的结果来看，积极应用单步自酸蚀粘合剂可能有助于确保粗糙釉质表面的形成，并增强树脂单体渗透到表面下脱矿釉质中。
Single-step self-etch adhesive systems have been developed to simplify and shorten bonding procedures. With the gain in popularity of these simplified systems, their reliability has become a focus of interest. The purpose of this study was to determine the effect of adhesive application method on enamel bond strength. Two commercial single-step self-etch adhesive systems, Clearfil tri-S Bond, and G-Bond, were used. Bovine mandibular incisors were mounted in self-curing resin and the facial enamel surfaces were ground wet on 600-grit SiC paper. Adhesives were only applied without agitation (inactive) or were agitated by a brush (active), and resin composites were condensed into the mold on the enamel surface and light-activated. Ten specimens per test group were stored in water at 37 degrees C for 24 h, then shear-tested at a cross-head speed of 1.0 mm/min. Two-way ANOVA followed by the Tukey HSD test were used. The bond strengths for active application were higher than those for inactive application. Significant differences were found for both adhesive systems. From the results of this study, active application of single-step self-etch adhesive may help to ensure the creation of a roughened enamel surface and enhance the penetration of resin monomer into the subsurface demineralized enamel.
