Can surface protection prevent damage in margins of composite resin restorations after simulated endogenous erosion?
Aim: The study investigated the effect of using surface protection agents in the adaptation of external and internal margins of restorations subjected to simulated erosion.Methods: Cavities with margins in dentin were prepared in bovine incisors (n=120).Adhesive restorations were placed using a three-step etch&rinse adhesive system and nanofilled c
