Atraumatic restorative treatment restorations performed with high-viscous GIC present similar survival/success rates to conventional approach using composite resin or amalgam for occlusoproximal restorations in primary teeth and can be suggested as a good option for occlusoproximal cavities in primary molars .
BACKGROUND Atraumatic restorative treatment ( ART ) has demonstrated good longevity when used for single-surface restorations , but lower success rates are reported for occlusoproximal surfaces .
AIM This systematic review and meta- analysis aim ed to verify the pooled success rate of  occlusoproximal ART restorations in primary teeth considering the outcomes : longevity , pulp damage , or caries lesion progression .
Mineral loss on adjacent enamel glass ionomer cements restorations after cariogenic and erosive challenges.
OBJECTIVES the purpose of this study was to determine the mineral loss on surrounding enamel restored with glass ionomer cements ( GIC ) after erosive and cariogenic challenges . METHODS Bovine enamel specimens were r and omly assigned into six groups according to the restorative material : G1 - composite resin ; G2 - high viscous GIC ; G3 - resin-modified glass ionomer with nanoparticles ; G4 - encapsulated resin-modified GIC ; G5 - encapsulated high viscous GIC ; G6 - resin-modified GIC . After restorative procedures , half of specimens in each group were su bmi tted to caries challenge using a pH cycling model for 5 days , and the other half were su bmi tted to erosive challenge in citric acid for 10 min . Before and after the challenges , surface Knoop microhardness assessment s were performed and mineral changes were calculated for adjacent enamel at different distances from restorative margin . RESULTS Data were compared for significant differences using two-way ANOVA and Student-Newman-Keuls tests ( p<0.05 ) . Erosive challenge significantly reduced enamel surface hardness , but no significant difference was observed irrespectively restorative material s ( p>0.05 ) . The cariogenic challenge promoted a higher surface hardness loss for the resin-modified GIC ( G4 ) and only for the High viscous GIC ( G2 ) an increase in surface hardness was observed . For enamel analyses , significant differences were observed with respect to the different material s ( p<0.001 ) and distances ( p=0.023 ) . Specimens restored with the composite resin presented higher mineral loss and specimens restored with the conventional high viscous GIC and the encapsulated resin-modified GIC presented the lowest values for mineral loss . CONCLUSION The GICs exerts protective effect only for cariogenic challenge
