The irrigation dynamics between conventional needle irrigation and other irrigation techniques were evaluated using computational fluid dynamics (CFD) in the current systematic review. Following the inclusion and exclusion criteria, the electronic databases (PubMed, Scopus and Web of Science) were searched until June 2022. Studies comparing conventional needle irrigation with various other techniques of irrigation were included. Two reviewers each independently evaluated the included articles. A total of 329 articles were obtained, from which 23 papers were included for full-text review. Out of which 18 were excluded and finally, 5 articles were considered. The risk of bias for in vitro studies was reported following modified JBI criteria and CRISS recommendations. The parameters assessed were shear stress, irrigant replenishment, velocity, turbulence, and apical pressures. We conclude from the current systematic review that irrigation dynamics in negative pressure systems were enhanced over syringe needle irrigation.
