The number of both luting agents and restorative materials available on the market has rapidly increased. This study compared various types of luting agents when used to bond different indirect, laboratory restorative materials to dentin. Cylinders were produced of six restorative materials (gold alloy, titanium, feldspathic porcelain, leucite-glass ceramic, zirconia, and an indirect resin composite). Following relevant pretreatment, the end surface of the cylinders were luted to ground, human dentin with eight different luting agents (DeTrey Zinc [zinc phosphate cement], Fuji I [conventional glass ionomer cement], Fuji Plus [resin-modified glass ionomer cement], Variolink II [conventional etch-and-rinse resin cement], Panavia F2.0 and Multilink [self-etch resin cements], RelyX Unicem Aplicap and Maxcem [self-adhesive resin cements]). After water storage at 37 °C for one week, the shear bond strength of the specimens was measured and the fracture mode was examined stereo-microscopically. Restorative material and luting agent both had a significant effect on bond strength and there was a significant interaction between the two variables. The zinc phosphate cement and the glass ionomer cements resulted in the lowest bond strengths, whereas the highest bond strengths were found with the two self-etch and one of the self-adhesive resin cements.
市场上可用的粘结剂和修复材料的数量迅速增加。本研究比较了用于将不同的间接实验室修复材料粘结到牙本质上时的各种粘结剂。制备了六种修复材料(金合金、钛、长石质瓷、白榴石玻璃陶瓷、氧化锆和间接树脂复合材料)的圆柱体。经过相关预处理后,将圆柱体的端面用八种不同的粘结剂粘结到磨平的人牙本质上(DeTrey Zinc[磷酸锌水门汀]、Fuji I[传统玻璃离子水门汀]、Fuji Plus[树脂改性玻璃离子水门汀]、Variolink II[传统酸蚀冲洗树脂水门汀]、Panavia F2.0和Multilink[自酸蚀树脂水门汀]、RelyX Unicem Aplicap和Maxcem[自粘结树脂水门汀])。在37℃下储存一周后,测量试件的剪切粘结强度,并通过立体显微镜检查断裂模式。修复材料和粘结剂均对粘结强度有显著影响,且这两个变量之间存在显著的相互作用。磷酸锌水门汀和玻璃离子水门汀的粘结强度最低,而两种自酸蚀树脂水门汀和一种自粘结树脂水门汀的粘结强度最高。
