The aim of this study to systematically review the literature using in vitro studies to investigate if cleaning post-space preparation with different irrigants can increase the retention of fiberglass post evaluated by push-out test. The present systematic review reports the results according to guidelines of PRISMA statement. The research question was developed according to the PICO strategy. Two electronic databases including PubMed and Ovid (MEDLINE) were used to find relevant studies. Two reviewers independently screened titles and abstracts through the databases and performed evaluation of risk of bias of the included studies. After study selection, only 11 studies met the inclusion criteria and were included in the systematic review. There was significant heterogeneity in the methodological variables, and therefore, it was impossible to perform valid quantitative synthesis of the data (meta-analysis). Insufficient evidence was found to indicate any of the irrigation solutions used to their effect on bond strength of self adhesive resin cement to root dentin. It is impossible to conclude recommendations to a specific irrigation protocol. Future studies should follow a standardized approach to implementation, same methodologies and reporting of data. Recommendations have been provided for standard methods of future studies so that clinical recommendations could be provided.
