The post-and-core systems and dental crowns are some of the main reconstructions of residual crowns or roots. The fiber posts are thought to have excellent physical and chemical properties that have been gaining an increasing number of clinical applications. Clinical studies have indicated that fiber posts could extend the life of endodontically-treated teeth and reduce the risk of root fractures. However, problems of adhesive failure may arise. Numerous experimental studies have developed methods for enhancing the bond strength of fiber posts. Resin adhesives can be viewed as the bridge that connects the fiber post to intraradicular dentin and is a very important component for fiber post retention. In this review, the effects of resin adhesives on the bonding effect of fiber posts from recent studies were summarized to provide a more solid basis in clinical applications.
