Statement of Problem: Well bonding of fiber posts inside the root canal is based on the formation of hybrid layer (HL). After mechanical post space preparation, final rinse with irrigants before fiber post cementation is used to dissolve the smear layer and encourage the formation of HL. The purpose of this review was to investigate the effects of pretreatment of the root canal using different irrigants on push-out bond strength of luted fiber posts. Material and Methods: A computerized literature search for studies based on English-language was conducted on PubMed between 2012 and 2022. Results: Thirty-five studies met the eligibility criteria. The most studied surface treatments were NaOCl, CHX, EDTA, and the association NaOCl with EDTA. The results were highly contentious. But most dentin surface treatments and bonding systems used have strengthened the bond between the posts and the dentin surface. Conclusion: The review found insufficient evidence to conclude on the best final rinse irrigator. Additional studies with test standardization and well-reported randomized clinical studies considering occlusal forces and tooth position in the arch are required.
