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. da Cunha CM, Wambier LM, Paris Matos TD, .
