The purpose of the present study was to compare bond strength of different universal adhesives under three different testing conditions: when no pretreatment was applied, after 37% phosphoric acid etching and after glycine application. One hundred and fifty bovine permanent mandibular incisors were used as a substitute for human teeth. Five different universal adhesives were tested: Futurabond M+, Scotchbond Universal, Clearfil Universal Bond, G-Premio BOND, Peak Universal Bond. The adhesive systems were applied following each manufacturer's instructions. The teeth were randomly assigned to three different dentin surface pretreatments: no pretreatment agent (control), 37% phosphoric acid etching, glycine pretreatment. The specimens were placed in a universal testing machine in order to measure and compare bond strength values. The Kruskal-Wallis analysis of variance and the Mann-Whitney test were applied to assess significant differences among the groups. Dentin pretreatments provided different bond strength values for the adhesives tested, while similar values were registered in groups without dentin pretreatment. In the present report, dentin surface pretreatment did not provide significant differences in shear bond strength values of almost all groups. Acid pretreatment lowered bond strength values of Futurabond and Peak Universal Adhesives, whereas glycine pretreatment increased bond strength values of G Praemio Bond adhesive system.
未进行预处理时、经37%磷酸酸蚀后以及应用甘氨酸后。使用150颗牛下颌恒切牙替代人牙。测试了五种不同的通用粘结剂：Futurabond M+、Scotchbond Universal、Clearfil Universal Bond、G-Premio BOND、Peak Universal Bond。按照各制造商的说明应用粘结剂系统。将牙齿随机分为三种不同的牙本质表面预处理组：不使用预处理剂（对照组）、37%磷酸酸蚀、甘氨酸预处理。将标本置于万能试验机中以测量和比较粘结强度值。应用Kruskal-Wallis方差分析和Mann-Whitney检验来评估各组之间的显著差异。牙本质预处理为所测试的粘结剂提供了不同的粘结强度值，而在未进行牙本质预处理的组中记录到了相似的值。在本报告中，牙本质表面预处理在几乎所有组的剪切粘结强度值方面未提供显著差异。酸预处理降低了Futurabond和Peak Universal粘结剂的粘结强度值，而甘氨酸预处理增加了G Praemio Bond粘结剂系统的粘结强度值。
