Objective: To evaluate the 2-year survival rate and the cost-effectiveness of Atraumatic Restorative Treatment (ART) using three different glass ionomer cements (GICs) for restoring occlusal dentin caries lesions in primary molars., Methods: One hundred and fifty (150) 4-8-year-old children were selected, randomly allocated and treated in school tables according to the restorative material: Fuji IX Gold Label (GC Corp), Vitro Molar (nova DFL) and Maxxion R (FGM), the latter two being low-cost brands. Materials and professionals' costs were considered to analyse baseline total cost, and from this the cumulative cost of each treatment was calculated. Restoration assessments were performed after 2, 6, 12 and 24 months by an independent calibrated examiner. Restoration survival was estimated using Kaplan-Meier survival analysis and Cox regression was used to test association with clinical factors. Bootstrap regression (1,000 replications) compared material´s cost over time and Monte-Carlo simulation was used to build cost-effectiveness scatter plots., Results: The overall survival rate of occlusal ART restorations after 2 years was 53% (Fuji IX = 72.7%; Vitro Molar = 46.5%; Maxxion R = 39.6%). Restorations performed with Vitro Molar and Maxxion R were more likely to fail when compared to Fuji IX. At baseline, Fuji IX was the more expensive option (p < 0.001), however, considering the simulation of accumulated cost caused by failures until 2-year evaluation, no difference was found between the groups., Conclusions: After 2 years' follow up, restorations performed with Fuji IX proved to be superior in terms of survival, with a similar overall cost, when compared to low-cost glass ionomers cements (Vitro Molar and Maxxion R)., (Copyright © 2020 Elsevier Ltd.

Introduction: The high costs of the worldwide recommended GICs might be a barrier for the implementation of ART. To overcome this problem, low cost GIC are used even though there is a lack of evidence for the survival rate of restorations., Objectives: To evaluate the performance of low-cost GICs used on occlusal ART restorations after one year., Methods: A total of 150 primary molars in 150 children with occlusal caries lesions were selected in 4-8 year-old children. The patients were randomly allocated in three groups: G1-GC Gold Label 9 (GC Corp); G2-Vitro Molar (DFL) and G3-Maxxion R (FGM). All treatments were performed following the ART premises in school setting. Restorations were evaluated after 2, 6 and 12 months. Restoration survival was evaluated using Kaplan-Meier survival analysis and Log-rank test and Cox regression was used for testing association with clinical factors (α=5%)., Results: GC Gold Label 9 had better performance compared to the low-cost GICs (HR=1.47, CI=1.04-2.08, p=0.027). The overall SR of restorations was 65.33% and the SR per group was G1=77.55%; G2=61.11% and G3=42.55%., Conclusions: The low-cost GICs have a poorer performance than GC Gold Label 9 in occlusal ART restoration in primary molars., (Copyright © 2016.
