Abstract

Good survival rates for single-surface Atraumatic Restorative Treatment (ART) restorations have been reported, while multi-surface ART restorations have not shown similar results. The aim of this study was to evaluate the survival rate of occluso-proximal ART restorations using two different filling materials: Ketac Molar EasyMix (3M ESPE) and Vitro Molar (DFL). A total of 117 primary molars with occluso-proximal caries lesions were selected in 4 to 8 years old children in Barueri city, Brazil. Only one tooth was selected per child. The subjetcs were randomly allocated in two groups according to the filling material. All treatments were performed following the ART premises and all restorations were evaluated after 2, 6 and 12 months. Restoration survival was evaluated using Kaplan-Meier survival analysis and Log-rank test, while Cox regression analysis was used for testing association with clinical factors (α = 5%). There was no difference in survival rate between the materials tested, (HR = 1.60, CI = 0.98-2.62, p = 0.058). The overall survival rate of restorations was 42.74% and the survival rate per group was Ketac Molar = 50,8% and Vitro Molar G2 = 34.5%). Cox regression test showed no association between the analyzed clinical variables and the success of the restorations. After 12 months evaluation, no difference in the survival rate of ART occluso-proximal restorations was found between tested materials.

Summary

Introduction

Submitted: Mar 02, 2017 Accepted for publication: Sept 11, 2017 Last revision: Sept 15, 2017. Atraumatic Restorative Treatment (ART) is a minimally intervention approach that involves preventive measures, sealing and fillings cavities. ART is recommended by the World Health Organization for bringing restorative care to people without access to dental attention.[2] The indication of ART was initially restricted to the treatment of teeth with cavities that, with no other treatment available, would lead to tooth extraction in less privileged communities in developing countries. The successful treatment of these teeth, through high-quality restorations, led to questioning if the ART approach could bring benefits to dental treatments in developed countries.[3] The extension of ART indications is
