Amalgam x Composite Resin: supplies and restorative procedures more performed among Oral Health Teams in Brazil

Abstract This study aimed to compare the availability of supplies and amalgam composite resin restorations among Oral Health Teams (OHT) in Brazilian regions. Secondary data were extracted from Modules I II 1st (2012) V VI 2nd (2014) 3rd cycle (2017) external evaluation National Program for Access Quality Primary Care2. The proportions between regions cycles compared using Chi-square test with z-test adjusted by Bonferroni method (p<0.05). Among 2012, 2014, 2017 there was a significant reduction proportion OHT that performed (87.5%, 89.2%, 80.2%; p<0.001) an increase (92.5 %, 97.7%, 99.0%; p<0.001), same trend (p<0.001). Amalgamator decreased 2012 (99.0%), 2014 (98.4%) (85.6%) Amalgam lower (80.1%), (87.5%) (97.5%) light curing (p<0.001), being less available North (95.7%) light-curing increased (94.1%), (96.6%) (97.0%) no only (p=0.134). While restoration, period evaluated all However, regional disparities are still evident, fewer restorative services region.
