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 .
The longevity of different restorations in primary teeth.
BACKGROUND AND AIM This paper review s three published papers and adds results from a fourth study which aim ed to determine which restorative material would be the best alternative(s ) to amalgam ( AM )  in primary teeth . DESIGN All studies had a practice -based design and were part of the routine treatment of children and adolescents . The clinicians were assigned which material s to use in a r and omised matter in the first three studies which lasted for 7 - 8 years . In the fourth study conducted 4 years after the initial studies , the clinicians were free to select the restorative material s. RESULTS AND CONCLUSIONS Resin modified glass ionomer ( RMGI ) and compomer ( COM ) restorations showed similar longevity compared with AM , whereas conventional GI restorations showed significantly shorter longevity . The studies indicated that the ' new and improved ' material s based on in vitro tests did not always show enhanced clinical properties . In the last study , where clinicians freely selected the restorative material s they used in their practice s , seven used COM , one used conventional GI material s and one used a combination of the two types of material
