Silver amalgam versus resin modified GIC class-II restorations in primary molars: twelve month clinical evaluation.

ABSTRACT

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%).
