The clinical performance of new restorative materials must be evaluated before recommending its use in primary teeth.
This randomized clinical trial evaluated the survival rates of restorations in single and occluso-proximal cavities of primary teeth performed with a new dual-cure resin-based material in comparison with a resin-modified glass ionomer cement after 12 months of follow-up.
A total of 107 restorations were placed in 27 children by one experienced pediatric dentist. Two materials were tested: Vitremer and a dual-cure resin-based material with (CentionN+Adh) and without (Cention N-Adh) adhesive system application. Two calibrated and blinded examiners evaluated the restorations at 3, 6, and 12-month. The longevity of the restorations was analyzed using Kaplan-Meier survival curves and Log-rank test (α = 5%).
The overall survival rates after 12-month were 81.9% for Vitremer, 70.4% for Cention N+Adh, and 66.7% for Cention N-Adh, which had the poorer performance (HR = 0.54; 95% CI= 0.31-0.95; = 0.031). When considering the type of the cavities, the difference was significant only for occluso-proximal cavities when Cention N-Adh was used (HR = 0.46; CI = 0.26-0.81; = 0.008).
All evaluated materials are suitable for restoring occlusal cavities after selective caries removal. However, Cention N needs to be used with adhesive in occluso-proximal cavities.
Cention-N can be used for deciduous teeth restorations, with similar longevity rates as resin modified glass ionomer cements.Trial registration number RBR-9nqszr.

在推荐将新型修复材料用于乳牙之前，必须对其临床性能进行评估。
本随机临床试验评估了一种新型双固化树脂基材料与树脂改性玻璃离子水门汀相比，在乳牙单颗及咬合-邻面洞修复后12个月的修复体生存率。
一名经验丰富的儿科牙医为27名儿童共放置了107颗修复体。测试了两种材料：Vitremer和一种使用（CentionN+Adh）及未使用（Cention N-Adh）粘结系统的双固化树脂基材料。两名经过校准且不知情的检查者在3个月、6个月和12个月时对修复体进行评估。使用Kaplan-Meier生存曲线和对数秩检验（α = 5%）分析修复体的使用寿命。
12个月后的总体生存率，Vitremer为81.9%，Cention N+Adh为70.4%，Cention N-Adh为66.7%，后者表现较差（HR = 0.54；95% CI = 0.31 - 0.95；P = 0.031）。考虑到龋洞类型时，仅在使用Cention N-Adh修复咬合-邻面洞时差异具有统计学意义（HR = 0.46；CI = 0.26 - 0.81；P = 0.008）。
所有评估材料均适用于选择性龋病去除后的咬合面洞修复。然而，Cention N在咬合-邻面洞修复中需要与粘结剂一起使用。
Cention-N可用于乳牙修复，其使用寿命与树脂改性玻璃离子水门汀相似。试验注册号RBR-9nqszr。
