摘　　要：目的:比较Clearfil SE Bond(SE)、AdperTM Easy One(EO)、Scotchbond Universal(SBU)3种自酸蚀粘接系统对乳牙釉质和牙本质粘接耐久性的影响,以及粘接界面轻度唾液污染后即刻吹干对粘接耐久性的影响。方法:将240个乳牙釉质及240个牙本质样本随机分为16组(n=15个/组),实验组选用SE、EO、SBU等3种不同自酸蚀粘接系统,对照组选用AdperTM Single Bond Plus(SL)全酸蚀粘接系统,在无污染或有唾液污染、蒸馏水储存(水浴储存24 h)或水浴循环老化(5℃和55℃水浴中循环5000次)等两种不同储存条件下,测量每组中12个试样的剪切粘接强度,用扫描电子显微镜观察分析剩余3个试样的粘接界面情况。采用三因素方差分析法和Tukey检验对数据进行统计学分析。结果:对于乳牙牙釉质粘接,全酸蚀粘接剂的即刻剪切粘接强度(28.92±1.83)MPa和老化后剪切粘接强度(27.27±3.03)MPa均显著高于其他组,差异有统计学意义(P<0.01);EO组有唾液污染时即刻剪切粘接强度(11.88±3.17)MPa或老化后剪切粘接强度(11.90±3.98)MPa均显著低于其无唾液污染时的即刻剪切粘接强度(19.57±3.89)MPa或老化后剪切粘接强度(19.01±5.03)MPa,差异有统计学意义(P<0.01)。对于乳牙牙本质的粘接,老化处理后全酸蚀粘接剂的剪切粘接强度(14.31±1.97)MPa显著低于其他粘接剂组,差异有统计学意义(P<0.01);EO组有唾液污染时的即刻剪切粘接强度(12.99±2.66)MPa显著低于其无唾液污染时剪切粘接强度(18.63±3.61)MPa,差异有统计学意义(P<0.01);EO组的无/有污染状态下的剪切粘接强度[(14.41±2.68)MPa和(10.93±2.18)MPa]均显著低于SE组[(21.10±4.40)MPa和(19.56±3.64)MPa]和SBU组[(22.27±5.43)MPa和(20.60±5.11)MPa],差异有统计学意义(P<0.01)。结论:全酸蚀粘接剂对乳牙釉质粘接耐久性更佳;SE和SBU对乳牙牙本质有更好的粘接耐久性;粘接界面轻度唾液污染后即刻吹干处理可恢复SE和SBU的粘接强度,但对EO的Objective:To compare the bonding durability of three different self-etch adhesives to primary enamel and dentin,and to investigate the effect of mild salivary contamination followed by air drying on the bonding durability.Methods:Two hundred and forty enamel specimens were divided randomly into 16 groups(n=15/group)according to the adhesive system[self-etch adhesives:Clearfil SE Bond(SE),AdperTM Easy One(EO),Scotchbond Universal(SBU);total-etch adhesive:AdperTM Single Bond Plus(SL)],contamination status(non-contaminated vs.salivary-contaminated)and storage condition(stored in distilled water for 24 h vs.aging mode 5000 thermal cycles in 5℃and 55℃).Two hundred and forty dentin specimens were assigned in the same way.Shear bond strength for 12 specimens in each group were measured.The adhesive interface for the residual specimens in each group was observed by scanning electron microscopy(SEM).Data were analyzed by three-way analysis of variance and Tukey test(P<0.05).Results:For primary enamel,total-etch adhesive showed higher initial shear bond strength values(28.92±1.83)MPa and shear bond strength values(27.27±3.03)MPa after thermal cycles compared with the other groups,and the difference between the groups was statistically significant(P<0.01).Shear bond strength values of EO decreased significantly in salivary-treated groups,regardless of storage conditions,and the difference was statistically significant(P<0.01).For primary dentin,shear bond strength values of EO decreased significantly in salivary-treated groups after 24 h(P<0.01).After 5000 thermal cycles,total-etch adhesive showed significantly lower shear bond strength values(14.31±1.97)MPa compared with the other groups,and the difference between the groups was statistically significant(P<0.01),and shear bond strength values of EO were significantly lower than those in SE and SBU groups(P<0.01),regardless of contamination status.Conclusion:Total-etch adhesive SL has better bonding durability to primary enamel.SE and SBU have better bonding durabili
