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 influence of restorative material on the survival rate of restorations in primary molars.
The survival rates of  restorations in primary molars were calculated after a retrospective examination of patients ' dental records from a study population of 1,065 children . A r and om sample of 128 records showing information for 604 dental restorations  was examined , coded , and analyzed by the life table method of survival analysis . The order of the survival rate of restorations from higher to lower success was preformed crowns , amalgam , composite resin , and glass ionomer restorations . A highly statistically significant difference ( P = 0.0001 ) was found among the survival success rates of different material restorations . For preformed crowns and amalgam restorations , the median survival time was more than 5 years . The 5-year survival estimate for preformed crowns was 68 % and for amalgam restorations was 60 % . For composite resin the median survival time was 32 months and the 4-year survival estimate was 40 % . For glass ionomer restorations , the median survival time was 12 months and the 4-year survival estimate was 5 %
