Atraumatic restorative treatment-ART in early childhood caries in babies: 4years of randomized clinical trial.

Abstract

To assess the effectiveness of atraumatic restorative treatment (ART) performed 4years ago in babies suffering from early childhood caries (ECC), and to compare the clinical performance of ART atraumatic restorations performed with two different high-viscosity glass ionomer cements (GIC). This was a longitudinal follow-up of a randomized, double-blind, split-mouth-type clinical trial. The initial sample was composed of 100 deciduous molars with occlusal lesions in 25 children with ages between 18 and 36months who received ART with two different GICs: Ketac Molar Easymix® (3M ESPE) and Vitro Molar® (DFL). The clinical assessments were performed by a trained, blind examiner gauged by the parameters assessed in 1, 2, and 4years (ART and USPHS criteria). For the analysis of the clinical performance of ARTs between the different GICs, the chi-square and Mann-Whitney tests were applied (p < 0.05). In the 4years of evaluation, the sample was composed by 76 ARTs and 19 children, with 94.7% of the treatments having inactivated the cavity process. The total success percentage of the ARTs was 94%, 87.5%, and 82.9%, in 1, 2, and 4years of follow-up, respectively. Moreover, among the GICs studied, this difference was not statistically significant (p > 0.05) ( ClinicalTrials.gov NCT03756025). ART was effective in handling ECC, with an excellent clinical performance of ART restorations, for both GICs, during the 4years of follow-up. ART, with both GIC studied, is an alternative therapy for ECC.
