Microleakage between conventional GIC, RMGIC and glass hybrid bulkfill restorative system to restore class I cavities in primary molars: An in vitro study.

Abstract

The microleakage of conventional GIC to that of resin modified GIC and bulk filled hybrid restorative system (GIC) to restore class I cavities in primary molars is of interest. Hence, a total of 60 extracted human primary molar teeth collected were divided into three main groups. Class I cavity was prepared in all teeth and restore with conventional GIC, resin modified GIC and bulk filled hybrid restorative system (GIC). Sections were viewed under stereomicroscope and the degree of microleakage was evaluated using specific scoring criteria. Among the three restorative materials, Glass hybrid Bulkfil restorative system GIC can be considered as the best material in the terms of microleakage.
