本研究的目的是评估人工唾液污染对三种修复材料的影响，即玻璃离子水门汀（GIC），树脂改性GIC（RMGIC），和复合树脂（CR），其中使用两种不同的蚀刻粘合剂系统。因此，使用人工唾液在牛牙齿上产生三种表面条件：对照、轻度唾液污染和严重唾液污染。人工唾液污染后，CR的牙本质粘结强度显著降低。然而，就GIC和RMGIC的牙本质和釉质粘结强度而言，三种表面条件之间没有显著差异。此外，CR表现出显着更大的人工唾液污染后的微渗漏，而GIC和RMGIC没有显着差异。结果表明，人工唾液污染不影响GIC和RMGIC的剪切粘结强度和微渗漏程度。
The purpose of this study was to evaluate the effects of artificial saliva contamination on three restorative materials, namely, a glass ionomer cement (GIC), a resin-modified GIC (RMGIC), and a composite resin (CR), for which two different etching adhesive systems were used. Thus, three surface conditions were created on bovine teeth using artificial saliva: control, mild saliva contamination, and severe saliva contamination. The dentin bond strength for CR was significantly lower after artificial saliva contamination There were, however, no significant differences among the three surface conditions in terms of the dentin and enamel bond strengths of GIC and RMGIC. Moreover, CR exhibited significantly greater microleakage after artificial saliva contamination, whereas no significant differences were found in GIC and RMGIC. The results showed that artificial saliva contamination did not affect the shear bond strengths of GIC and RMGIC or their degrees of microleakage.
