目的
评价通用粘合剂的蚀刻-冲洗或自蚀刻模式是否是优化人工诱导龋影响的原发性和永久性牙本质的粘结强度的最佳方案。
材料和方法
平坦的中冠牙本质表面暴露在24个乳磨牙和24个恒磨牙，并提交pH循环14天，以诱导人工龋影响的牙本质。对于每种牙齿类型（乳牙和恒牙），根据粘合剂系统和粘合策略将牙齿随机分配到4个不同的组：通用粘合剂Scotchbond Universal Adhesive，自酸蚀和蚀刻-冲洗模式;两步蚀刻-冲洗粘合剂Adper Single Bond 2（对照）;两步自酸蚀系统Clearfil SE Bond（对照）。在粘合和修复程序之后，将试样切片以获得矩形棒（0.8mm2），将其进行微拉伸测试（十字头速度：1 mm/min）。采用双因素方差分析（α = 0.05）分析数据。
结果
通用粘合剂的粘合强度与对照组相似，与粘合策略无关。同样，观察到所有粘合剂对人工诱导的龋齿影响的原生牙本质或永久牙本质的粘合性能在统计学上相似。
结论
新的通用粘合剂，Scotchbond通用粘合剂，可用于两种应用模式，在人工诱导龋影响的初级和永久牙本质，因为粘结强度不受不同的基板或应用模式。
PURPOSE
To evaluate whether the etch-and-rinse or self-etching mode of a universal adhesive is the best protocol to optimize bond strength to primary and permanent artificially-induced caries-affected dentin.
MATERIALS AND METHODS
Flat midcoronal dentin surfaces were exposed in 24 primary and 24 permanent molars and submitted to pH cycling for 14 days to induce artificial caries-affected dentin. For each tooth type (primary and permanent), the teeth were randomly assigned to 4 different groups according to the adhesive systems and bonding strategy: a universal adhesive, Scotchbond Universal Adhesive, in self-etching and etch-and-rinse modes; a twostep etch-and-rinse adhesive, Adper Single Bond 2 (control); and two-step self-etching system, Clearfil SE Bond (control). After bonding and restorative procedures, specimens were sectioned to obtain rectangular sticks (0.8 mm2) that were submitted to microtensile tests (crosshead speed: 1 mm/min). The data were analyzed using two-way ANOVA (α = 0.05).
RESULTS
The universal adhesive showed bond strengths similar to those of the control groups, irrespective of the bonding strategy. Likewise, statistically similar bonding performance was observed for all adhesives to either artificially- induced caries-affected primary or permanent dentin.
CONCLUSION
The new universal adhesive, Scotchbond Universal Adhesive, can be used in both application modes in artificially-induced caries-affected primary and permanent dentin, as the bond strength was not influenced by the different substrates or application mode.
