The effect of surface sealants with different filler content on microleakage of Class V resin composite restorations

摘要

Objective:Microleakage is still one of the most cited reasons for failure of resin composite restorations. Alternative methods to prevent microleakage have been investigated increasingly. The aim of this study is to evaluate the microleakage in Class V resin composite restorations with or without application of surface sealants with different filler content.
