Abstract To evaluate the influence of different adhesion strategies and curing modes of a universal adhesive on shear bond strength (SBS) of a dual-cured core build-up resin composite to bovine dentin. In total, 60 bovine anterior permanent teeth were randomly divided into 6 groups (n = 10/group) according to; 1: Adhesion strategy, 3 groups (self-etching, etch-and-rinse/wet and etch-and-rinse/dry) and 2: Curing mode, 2 groups (light-curing and dual-curing). Subsequent to root and incisal half removal of each tooth, labial enamel was wet ground over #180 SiC papers, and exposed dentin surface was wet ground over #600 SiC paper for 60 s to create a standardized smear layer. Universal adhesive was applied according to its manufacturer instructions and each tooth was then restored with one dual-cured composite cylinder (2mm×2mm). Shear bond strength was run at a crosshead speed of 0.5 mm/min, and failure modes were categorized into: 1- Adhesive, 2- Mixed and 3- Cohesive failures. Statistical analysis was performed using Two-Way ANOVA/Tukey HSD test. The results showed that factor ‘adhesion strategy’ had no statistically significant effect on SBS (p = 0.525). However, factors ‘curing mode’ and ‘adhesion strategy x curing mode’ showed statistically significant effect on SBS (p = 0.020 and p = 0.002 respectively). Mixed failure represented 55%, followed by adhesive failure (43.3%) and the cohesive failure represented 1.7%. It seemed better to apply the universal adhesive used in this study in etch-and-rinse strategy rather than self-etching one, especially when the adhesive was used in light-curing mode. The use of the DC activator seemed to be unnecessary.

通用型胶粘剂的黏附策略和固化方式影响双固化造芯树脂复合材料与牙本质的结合
摘要 评估通用粘合剂的不同粘合策略和固化模式对双固化核心构建树脂复合材料与牛牙本质的剪切粘合强度(SBS)的影响。将60颗牛前恒牙随机分为6组(n=10/组);1:粘合策略,3组(自蚀刻,蚀刻和冲洗/湿和蚀刻和冲洗/干燥)和2:固化模式,2组(光固化和双固化)。在去除每颗牙齿的牙根和切缘后,用#180 碳化硅纸湿磨唇釉,用#600 碳化硅纸湿磨暴露牙本质表面60 秒,以形成标准化的涂片层。根据制造商的说明使用通用粘合剂,然后用一个双固化复合圆柱体(2mm×2mm)修复每颗牙齿。剪切粘合强度以 0.5 毫米/分钟的十字头速度运行,失效模式分为:1- 粘合失效、2- 混合失效和 3- 内聚失效。使用双向方差分析/Tukey HSD 检验进行统计分析。结果表明,“粘附策略”因素对 SBS 没有统计学意义的影响 (p = 0.525)。然而,“固化模式”和“粘合策略 x 固化模式”因素对 SBS 显示出统计学上的显着影响(分别为 p = 0.020 和 p = 0.002)。混合破坏占 55%,其次是粘合破坏 (43.3%),内聚破坏占 1.7%。在蚀刻和冲洗策略中应用本研究中使用的通用粘合剂而不是自蚀刻策略似乎更好,尤其是当粘合剂用于光固化模式时。DC 活化剂的使用似乎是不必要的。
