The patients were randomly allocated in three groups: G1 –high-viscosity GIC restoration (EquiaFil–GC Corp); G2 –compomer(DyractExtra –Dentsply) and G3 –glass carbomercement (GCC -Glass Carbomer–GCP Dental). All treatments were and G3 –glass carbomercement (GCC -Glass Carbomer–GCP Dental). All treatments were performed following the ART premises and all restorations were evaluated after 2, 6, 12, 18 and 24 months by single evaluator. Restoration survival was evaluated by Kaplan-Meier survival analysis and Log-rank test, while Cox regression analysis was used for testing association with clinical factors (α = 5).Results: Two hundred eighty three (283) children were evaluated (drop-out=2.4%). There was difference in survival rate between the materials tested, with a poorer performance of GCC (HR=1.31; p=0.009; CI=1.07-1.61). No difference was found between GIC and COM (p=0.699). The overall survival rate of restorations was 58.3% and the survival rate per group was G1 = The overall survival rate of restorations was 58.3% and the survival rate per group was G1 = 57.51%; G2 = 52.75% and G3=39%. Cox regression test revealed influence of operator, presence of cavitatedlesion in the tooth surface adjacent to the restored surface and dmftin the survival of restorations.Conclusions: This study suggests that GCC is less suitable for the use in approximalART restorations in primary molars than high-viscosity GIC and compomer.This abstract is based on research that was funded entirely or partially by an outside source:source:FAPESP 2015/00565-3Disclosure Statement:The submitter must disclose the names of the organizations with which any author have a relationship, the nature of the relationship, and the clinical or research area involved.
