Abstract Purpose The aim of this study was to evaluate the microtensile bond strength (μTBS), degree of conversion (DC), and silver nitrate deposition (NL) of three universal adhesive systems, used in etch-and-rinse and self-etch modes, on wet and oversaturated dentin surfaces. Materials and methods Human molars were assigned to 12 groups by: Universal adhesive systems: (Ambar Universal APS [AMB]; Prime & Bond Active [PBA]; Scotchbond Universal Adhesive [SBU]; Adhesive strategies: (etch-and-rinse [ER] or self-etch [SE]); and Degree of surface moisture: (wet or oversaturated dentin surface). After restoration, the specimens were sectioned into resin-dentin beams and tested for μTBS, DC, and NL. A three-way ANOVA and Tukey's test were used for statistical analysis (5%). Results No significant difference was observed in μTBS (p > 0.14) and DC (p > 0.67) among the tested adhesives regardless of the adhesive strategy employed when dentin was kept wet. AMB (ER and SE) resulted in a higher mean μTBS and DC values when the dentin was kept oversaturated (p Conclusion Universal adhesives systems showed good adhesive performance to dentin when dentin was kept wet. However, in oversaturated dentin, the response is material dependent.

牙本质水分对通用粘合剂性能的影响

摘要 目的本研究的目的是评估三种通用粘合剂系统的微拉伸粘合强度 (μTBS)、转化度 (DC) 和硝酸银沉积 (NL)，用于蚀刻和冲洗模式和自蚀刻模式。 , 在潮湿和过饱和的牙本质表面。材料和方法 人类磨牙通过以下方式分为 12 组： 通用粘合剂系统：（Ambar Universal APS [AMB]；Prime & Bond Active [PBA]；Scotchbond Universal Adhesive [SBU]；粘合剂策略：（蚀刻和冲洗 [ER ] 或自酸蚀 [SE])；和 表面水分程度：（湿润或过饱和的牙本质表面）。修复后，将试样切成树脂-牙本质梁并测试 μTBS、DC 和 NL。三向ANOVA 和 Tukey's test 用于统计分析（5%）。结果在 μTBS 中没有观察到显着差异（p > 0。14) 和 DC (p > 0.67) 在测试的粘合剂中与牙本质保持湿润时采用的粘合剂策略无关。当牙本质保持过饱和时，AMB（ER 和 SE）导致更高的平均 μTBS 和 DC 值（p 结论当牙本质保持湿润时，通用粘合剂系统对牙本质显示出良好的粘合性能。然而，在过饱和牙本质中，响应取决于材料.
