The aim of the present study was to determine the influence of different adhesive application methods and etching modes on enamel bond effectiveness of universal adhesives using shear bond strength (SBS) testing and surface free-energy (SFE) measurements. The adhesives Scotchbond Universal, All-Bond Universal, Adhese Universal, and G-Premio Bond were used. Prepared bovine enamel specimens were divided into four groups, based on type of adhesive, and subjected to the following surface treatments: (i) total-etch mode with active application; (ii) total-etch mode with inactive application; (iii) self-etch mode with active application; and (iv) self-etch mode with inactive application. Bonded specimens were subjected to SBS testing. The SFE of the enamel surfaces with adhesive was measured after rinsing with acetone and water. The SBS values in total-etch mode were significantly higher than those in self-etch mode. In total-etch mode, significantly lower SBS values were observed with active application compared with inactive application; in contrast, in self-etch mode there were no significant differences in SBS between active and inactive applications. A reduction in total SFE was observed for active application compared with inactive application. The interaction between etching mode and application method was statistically significant, and the application method significantly affected enamel bond strength in total-etch mode.
本研究的目的是通过剪切粘结强度（SBS）测试和表面自由能（SFE）测量，确定不同的粘合剂应用方法和酸蚀模式对通用粘合剂牙釉质粘结效果的影响。使用了3M Scotchbond通用型粘结剂、全优粘结剂、Adhese通用型粘结剂和G-Premio Bond粘结剂。制备好的牛牙釉质标本根据粘合剂类型分为四组，并进行以下表面处理：（i）主动涂布的全酸蚀模式；（ii）非主动涂布的全酸蚀模式；（iii）主动涂布的自酸蚀模式；（iv）非主动涂布的自酸蚀模式。对粘结后的标本进行SBS测试。用丙酮和水冲洗后，测量涂有粘合剂的牙釉质表面的SFE。全酸蚀模式下的SBS值显著高于自酸蚀模式。在全酸蚀模式下，与非主动涂布相比，主动涂布时观察到的SBS值显著更低；相反，在自酸蚀模式下，主动涂布和非主动涂布之间的SBS没有显著差异。与非主动涂布相比，主动涂布时观察到总SFE降低。酸蚀模式和应用方法之间的相互作用具有统计学意义，并且应用方法在全酸蚀模式下显著影响牙釉质粘结强度。
