To evaluate the 18-month clinical performance of a universal adhesive, applied under different adhesion strategies, after selective carious tissue removal in primary molars.
Forty-four subjects (five to 10 years old) contributed with 90 primary molars presenting moderately deep dentin carious lesions on occlusal or occluso-proximal surfaces, which were randomly assigned following either self-etch or etch-and-rinse protocol of Scotchbond Universal Adhesive (3M ESPE). Resin composite was incrementally inserted for all restorations. Restorations were evaluated at one, six, 12, and 18 months using the modified United States Public Health Service criteria. Survival estimates for restorations' longevity were evaluated using the Kaplan-Meier method. Multivariate Cox regression analysis with shared frailty to assess the factors associated with failures (P<0.05).
Estimated survival rates of the restorations were 100 percent, 100 percent, 90.6 percent, and 81.4 percent at one, six, 12, and 18 months, respectively. The adhesion strategy did not influence the restorations' longevity (P=0.06; 72.2 percent and 89.7 percent with etch-and-rinse and self-etch mode, respectively).
Self-etch and etch-and-rinse strategies did not influence the clinical behavior of universal adhesive used in primary molars after selective carious tissue removal; although there was a tendency for better outcome of the self-etch strategy.
评估在乳牙选择性龋组织去除后，采用不同粘结策略应用通用粘结剂的18个月临床性能。
44名受试者（5至10岁）提供了90颗乳牙，这些乳牙在咬合面或咬合邻面有中度深的牙本质龋损，按照3M ESPE公司Scotchbond通用粘结剂的自酸蚀或酸蚀冲洗方案随机分配。所有修复体均采用分层充填树脂复合材料。使用改良的美国公共卫生服务标准在1、6、12和18个月时对修复体进行评估。使用Kaplan-Meier方法评估修复体寿命的生存估计值。采用具有共享脆弱性的多变量Cox回归分析来评估与失败相关的因素（P<0.05）。
修复体在1、6、12和18个月时的估计生存率分别为100%、100%、90.6%和81.4%。粘结策略不影响修复体的寿命（P=0.06；酸蚀冲洗和自酸蚀模式下分别为72.2%和89.7%）。
自酸蚀和酸蚀冲洗策略不影响乳牙选择性龋组织去除后通用粘结剂的临床性能；尽管自酸蚀策略有更好结果的趋势。
