| Abstract | |
The aim of this study was to evaluate if the new nanoparticulate material, the glass carbomer can increase the survival rate of occlusal-proximal-ART restorations compared with compomer - a polyacid resin modified material and a high viscosity glass ionomer cement (GIC). A total of 286 children aged 5 to 7 years presenting at least one occlusal-proximal carious lesion were selected in the city of Barueri, SP. Patients were randomized into three groups: high viscosity GIC (GIC - Fuji IX Extra - GC Corp), Compomer (COM - Dyract Extra - Dentsply) and Glass Carbomer (CAR - Glass Carbomer - GCP Dental). All treatments were made following the precepts of ART and manufacturers\' recommendations. The restorations were evaluated after 2, 6 and 12 months by a trained examiner. To verify the survival of the restorations was used Kaplan-Meier survival analysis and log-rank test. To evaluate the association between the outcome and patient variables was applied Cox regression test. The significance level for the tests was 5%. After 12 months of follow-up, overall survival rate of the restorations was 52.8%. The GIC, COM and CAR survival rate were 62.6%, 61.3% and 36.3%, respectively. Statistical analysis showed significant differences between the materials, where the CAR had a worse performance (HR = 1.84, CI 1.19 to 2.85; p = 0.006) and no difference was found between the CIV and COM materials. Moreover, statistical differences were found for the variable volume of the cavity, where smaller cavities had higher chances of failure (p <0.03). We conclude that the new glass carbomer material is not suitable for use in ART occlusal-proximal restorations in primary molars compared to high viscosity GIC and the compomer. (AU) | |
