Background and Aim: Evaluating the effect of different surface treatment methods on flexural strength (FS) and elasticity modules (EM) related to fiber posts is very important. The main purpose of this study was to evaluate the effect of different surface treatment methods on FS and EM of quartz and glass fiber-based posts in the form of a narrative review study. Materials and Methods: To conduct this study, all studies related to the subject under discussion during the years 2022–2000 by systematic search in internationally available databases, including Web of Science, Science Direct, Scopus, PubMed, and Google Scholar, were checked out. Finally, completely relevant studies were selected to investigate the main objective. Results: The results showed that before surface preparation, FS and elasticity coefficient (EC) of quartz fiber-based posts were higher than glass fiber. According to the results of some previous studies, surface preparation of glass and quartz fiber posts by laser and 10% hydrogen peroxide has no effect on their FS and elasticity. Findings of some other studies showed that the laser method than air abrasion can be a more suitable method for preparing the surface of fiber posts before the bonding process. In some other studies, it was reported that the Airborne-particle abrasion (Al2O3) method produced a higher amount of FS than the laser. Conclusion: Based on the results of previous similar studies, it can be concluded that the results of previous studies are very contradictory, and therefore, it is not possible to provide a completely superior surface treatment method to increase flexural strength. The amount of flexural strength depends mainly on the intrinsic properties of the fiber post.
