This is a secondary outcome of a three-year randomised controlled trial that compared Atraumatic Restorative Treatment (ART) to the Hall Technique (HT) for managing occluso-proximal caries lesions in primary molars. The primary outcome showed that the HT had a higher survival rate compared to ART and the economic evaluation was to test cost-effectiveness.<h4>Methods</h4>Children (5-10 years old) in public schools of Tietê-SP/Brazil, were randomly allocated to either the ART or HT arm. Treatment survival was assessed using Kaplan-Meier analysis. The economic evaluation considered baseline and cumulative material and professional costs based on the Brazilian National Health SBMC oral healthEconomic Evaluation of ART and Hall in Primary Molars.PMC123628912015/18098-2310972/2021-3Olegario ICde Araujo MPInnes NPBraga MMHesse DMendes FMRaggio DPGarbim JRBonifacio CCfalseEconomic Evaluation of ART and Hall in Primary Molars.<h4>Background</h4>This study reports an economic evaluation from the perspective of the Brazilian healthcare system.
