The aim of this study was to evaluate (a) the reactivity of six universal dental adhesives with polished cobalt-chrome (Co-Cr) alloy and zirconia (3Y-TZP) surfaces; and (b) to assess the shear bond strength (SBS) of a resin composite with polished and alumina-blasted surfaces as mediated by these adhesives. The products tested were Adhese Universal (AD), All-Bond Universal (AB), Clearfill Universal Bond (CB), G-Premio Bond (GP), Prelude One (PO) and Scotchbond Universal (SB). The reactivity on polished substrates was evaluated by reflection infrared microscopy (RFTIRM). The roughness parameters of polished and 50 μm alumina grit-blasted surfaces were assessed by optical profilometry. The SBS of the composite bonded to the substrates treated with each adhesive (n = 10/product) was evaluated after 1 week of storage (HO/37 °C) by Weibull statistics. Evidence of phosphate interaction with polished substrates was obtained by FTIRM, with higher peaks on the alloy. Alumina-blasting increased all roughness parameters with higher values on the alloy. AD, CB were the strongest () treatments on alloy surfaces and AD, CB, AB, SB on zirconia. GP was the weakest on both substrates and the least reliable () on alloy. On polished alloy GP, PO performed better (), whereas on zirconia there were no significant differences. All adhesives showed more prominent reaction with the Co-Cr alloy than with 3Y-TZP.
(a) 六种通用牙科粘合剂与抛光钴铬（Co-Cr）合金和氧化锆（3Y-TZP）表面的反应性；以及 (b) 由这些粘合剂介导的树脂复合材料与抛光和氧化铝喷砂处理表面之间的剪切粘结强度（SBS）。所测试的产品有Adhese Universal（AD）、All-Bond Universal（AB）、Clearfill Universal Bond（CB）、G-Premio Bond（GP）、Prelude One（PO）和Scotchbond Universal（SB）。通过反射红外显微镜（RFTIRM）评估在抛光基材上的反应性。通过光学轮廓仪评估抛光和50μm氧化铝喷砂处理表面的粗糙度参数。在储存1周（HO/37°C）后，通过威布尔统计评估与每种粘合剂处理的基材粘结的复合材料的SBS（n = 10/产品）。通过FTIRM获得磷酸盐与抛光基材相互作用的证据，合金上的峰值更高。氧化铝喷砂增加了所有粗糙度参数，合金上的值更高。AD、CB是合金表面上最强的（）处理，AD、CB、AB、SB是氧化锆表面上最强的。GP在两种基材上都是最弱的，在合金上最不可靠（）。在抛光合金GP上，PO表现更好（），而在氧化锆上没有显著差异。所有粘合剂与Co-Cr合金的反应比与3Y-TZP的反应更明显。
