Comparative in vitro evaluation of internal adaptation of resin-modified glass ionomer flowable composite and bonding agent applied as a liner under composite restoration: A scanning electron microscope study

摘要

Background:The use of resin-modified glass Ionomer cement in sandwich technique is widely practiced with the advent of various newer generation of composites the bond between resin-modified glass Ionomer and these resins should be validated. This study is done to evaluate the interfacial microgaps between different types of liners and dentin, liners and composite (Filtek p60 [FLp60]) using scanning electron microscope (SEM).
