The aim was to compare eight types of luting agents when used to bond six indirect, laboratory restorative materials to dentin. Cylinders of the six restorative materials (Esteticor Avenir [gold alloy], Tritan [titanium], NobelRondo [feldspathic porcelain], Finesse All-Ceramic [leucite-glass ceramic], Lava [zirconia], and Sinfony [resin composite]) were ground and air-abraded. Cylinders of feldspathic porcelain and glass ceramic were additionally etched with hydrofluoric acid and were silane-treated. The cylinders were luted to ground human dentin with eight 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], and 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 (n=8/group) was measured, and the fracture mode was stereomicroscopically examined. Bond strength data were analyzed with two-factorial analysis of variance (ANOVA) followed by Newman-Keuls' Multiple Range Test (α=0.05). Both the restorative material and the luting agent had a significant effect on bond strength, and significant interaction was noted between the two variables. Zinc phosphate cement and glass ionomer cements produced the lowest bond strengths, whereas the highest bond strengths were found with the two self-etch and one of the self-adhesive resin cements. Generally, the fracture mode varied markedly with the restorative material. The luting agents had a bigger influence on bond strength between restorative materials and dentin than was seen with the restorative material.
目的是比较 8 种粘固剂在将 6 种间接实验室修复材料粘接到牙本质时的效果。将 6 种修复材料（Esteticor Avenir[金合金]、Tritan[钛]、NobelRondo[长石质瓷]、Finesse All-Ceramic[透锂长石玻璃陶瓷]、Lava[氧化锆]和 Sinfony[树脂复合材料]）的圆柱体进行研磨和空气喷砂处理。长石质瓷和玻璃陶瓷的圆柱体还使用氢氟酸进行蚀刻，并进行硅烷处理。将圆柱体用 8 种粘固剂（DeTrey Zinc[磷酸锌粘固粉]、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-冲洗树脂粘结剂]、Panavia F2.0 和 Multilink[自酸蚀树脂粘结剂]以及 RelyX Unicem Aplicap 和 Maxcem[自粘接树脂粘结剂]）粘接到研磨后的人牙本质上。在 37°C 下储存 1 周后，测量试件的剪切粘结强度（n=8/组），并使用立体显微镜检查断裂模式。使用双因素方差分析（ANOVA）对粘结强度数据进行分析，然后进行 Newman-Keuls 多重范围检验（α=0.05）。修复材料和粘固剂对粘结强度均有显著影响，并且两个变量之间存在显著的相互作用。磷酸锌粘固粉和玻璃离子水门汀产生的粘结强度最低，而两种自酸蚀和一种自粘接树脂粘结剂的粘结强度最高。通常，断裂模式随修复材料的不同而有明显差异。与修复材料相比，粘固剂对修复材料和牙本质之间的粘结强度有更大的影响。
