Objective: This study explored the effects of different light curing modes and ethanol-wet bonding on dentin bonding strength and durability. Methods: A total of 54 molars were randomly divided into three groups: Single Bond 2, Gluma Comfort Bond, and N-Bond. Based on the three light-curing modes and presence or absence of ethanol pretreatment, the samples were assigned to six subgroups: high-light mode, ethanol pretreatment+high-light mode, soft-start mode, ethanol pretreatment+soft-start mode, standard mode, and ethanol pretreatment+standard mode. All samples were bonded with resin based on the experimental groups. After 24 h and 6 months of water storage, a universal testing machine was used to measure microtensile bond strength. scanning electron microscopy (SEM) was applied to observe mixed layer morphology. Results: The 24-h and 6-month microtensile bond strengths of the ethanol pretreatment groups were significantly higher than those of the non-ethanol pretreatment groups at the same light modes (P<0.05). With or without ethanol pretreatment, the microtensile bond strengths of the high-light modes were significantly lower than those of the soft-start modes and standard modes (P<0.05). The microtensile bond strengths of samples from the 6-month water storage group significantly decreased compared with those of samples from the 24-h water storage group (P<0.05). The soft-start groups and standard groups formed better mixed layers than the high-light mode groups, whereas the ethanol pretreatment groups formed more uniform mixed layers than those without ethanol pretreatment. Conclusions: ethanol-wet bonding technique, soft-start, and standard modes could improve dentin bonding properties.


方法:将Single Bond 2(SB)组、Gluma Comfort Bond(GB)组和N-Bond(NB)组分别分为6个亚组:高光照射模式、乙醇预处理+高光照射模式、软启动照射模式、乙醇预处理+软启动照射模式、标准照射模式和乙醇预处理+标准照射模式。按照分组粘结,水储24小时和6个月后,应用万能测试机分别检测微拉伸强度,体视显微镜观察微拉伸试件断裂类型和扫描电镜观察混合层形态。
