Artificially formed caries-like lesions around Class II glass ionomer restorations in primary molars

Abstract

The aim of this study was to investigate the microleakage around Class II glass ionomer restorations in primary molars. Two different glass ionomer cements and one amalgam control were assessed in vitro by acidified gel technique. Assessment of caries-like lesions was performed using polarized light microscopy. The traditional glass ionomer (Chemfil II) with dentin conditioner provided the highest protection against caries attack and the amalgam restorations provided the least.
