Restorations of primary molars with conventional glass ionomer cement showed increased risk of failure than compomer , resin-modified glass ionomer cement , amalgam , and composite resin .
This study aim ed to compare the longevity of different conventional restorative material s placed in posterior primary teeth .
Silver amalgam versus resin modified GIC class-II restorations in primary molars: twelve month clinical evaluation.
The purpose of this study was to compare the clinical efficacy of  resin modified GIC with amalgam as a restorative material , in Class-II cavities of primary molars . Restorations were evaluated at four , eight , and twelve months for their marginal integrity , anatomic form and development of recurrent caries . When each parameter was considered separately , there was no difference in the success rate between the two groups , except development of recurrent caries significantly less ( p<0.05 ) in RMGIC group(4.7 % ) compared to amalgam group ( 12.5 % ) at twelve month follow up . However , the cumulative success rate at 12 month was found to be significantly higher ( p<0.05 ) in RMGIC ( Fuji II LC ) group(83.1 % ) compared to amalgam(72 % )
