The overall results of the computed data sets suggest that GIC has a higher caries-preventive effect than amalgam for restorations in permanent teeth .
No difference was found for restorations in the primary dentition .
Background This article aims to up date the existing systematic review evidence elicited by Mickenautsch et al. up to 18 January 2008 ( published in the European Journal of Paediatric Dentistry in 2009 ) and addressing the review question of whether , in the same dentition and same cavity class ,  glass-ionomer cement ( GIC ) restored cavities show less recurrent carious lesions on cavity margins than cavities restored with amalgam .
Eight-year study on conventional glass ionomer and amalgam restorations in primary teeth
Abstract s on this page have been chosen and edited by Dr Trevor Watts Abstract Failure rates were higher for glass ionomer ( GIC ) , but caries progression was more likely on tooth surfaces adjacent to amalgam ( AM ) restorations
