Good survival rates for single-surface Atraumatic Restorative Treatment (ART) restorations have been reported, while multi-surface ART restorations have not shown similar results. The aim of this study was to evaluate the survival rate of occluso-proximal ART restorations using two different filling materials: Ketac Molar EasyMix (3M ESPE) and Vitro Molar (DFL). A total of 117 primary molars with occluso-proximal caries lesions were selected in 4 to 8 years old children in Barueri city, Brazil. Only one tooth was selected per child. The subjetcs were randomly allocated in two groups according to the filling material. All treatments were performed following the ART premises and all restorations were evaluated after 2, 6 and 12 months. Restoration survival was evaluated using Kaplan-Meier survival analysis and Log-rank test, while Cox regression analysis was used for testing association with clinical factors (α = 5%). There was no difference in survival rate between the materials tested, (HR = 1.60, CI = 0.98-2.62, p = 0.058). The overall survival rate of restorations was 42.74% and the survival rate per group was Ketac Molar = 50,8% and Vitro Molar G2 = 34.5%). Cox regression test showed no association between the analyzed clinical variables and the success of the restorations. After 12 months evaluation, no difference in the survival rate of ART occluso-proximal restorations was found between tested materials.
据报道，单面非创伤性修复治疗（ART）修复体的生存率良好，而多面ART修复体则未显示出类似的结果。本研究的目的是评估使用两种不同填充材料：Ketac Molar EasyMix（3M ESPE）和Vitro Molar（DFL）的咬合-邻面ART修复体的生存率。在巴西巴鲁埃里市4至8岁的儿童中，共选择了117颗患有咬合-邻面龋损的乳磨牙。每个儿童仅选择一颗牙齿。根据填充材料将受试者随机分为两组。所有治疗均按照ART的原则进行，所有修复体在2、6和12个月后进行评估。使用Kaplan-Meier生存分析和对数秩检验评估修复体的生存率，而Cox回归分析用于测试与临床因素的相关性（α = 5%）。所测试的材料之间的生存率没有差异，（风险比= 1.60，置信区间= 0.98 - 2.62，p = 0.058）。修复体的总体生存率为42.74%，每组的生存率分别为Ketac Molar = 50.8%和Vitro Molar G2 = 34.5%）。Cox回归检验显示，所分析的临床变量与修复体的成功之间没有关联。在12个月的评估后，在所测试的材料之间未发现ART咬合-邻面修复体生存率的差异。
