EndoVac (Apical negative pressure irrigation system) safely and predictably delivers irrigating solution to the apical terminus with penetration of irrigant into the anatomical complexities of root canal. In present article the available literature on EndoVac is reviewed from a MEDLINE database research. This article presents an overview of negative pressure irrigation and its safety, efficacy, efficiency and regenerative potential, removal of smear layer and debris, microbial reduction and assessment of post-operative pain after using negative pressure irrigation technique. Weather these parameters translate into a better clinical outcome remains to be seen.
