Objective: In recent years, due to the increasing of demand for tooth-colored posts, conventional metal posts have switched to various non-metallic posts, including fiber posts. Resistance to post-fiber displacement depends on their adhesion to the dentin. For fiber post cementation, self-etch, self-adhesive resin and glass ionomer cements are some of cementation materials that commonly used. the aim of this study was to compare the push-out straight between glass ionomer, self-etch and self-adhesive cements in fiber posts. Method: For this study, 30 extracted central teeth that have a similar anatomical structure and do not have structural problems and caries was used. the root canal for each specimen was prepared and the teeth were randomly divided into 3 groups (self-adhesive, self-etch and glass) (n=10) according to the cementation system. The specimens were then sectioned with de.. View More»
