In vitro microleakage study of a condensable and flowable composite resin

The aim of this study was to evaluate the in vitro microleakage of a condensable composite resin recommended for Class II restorations with and without a flowable composite resin as a liner. There were statistically significant differences between all groups and between individual groups (p < 0.05). The results showed significantly less microleakage in teeth restored with flowable composite resin underneath a condensable composite resin.
