Ninety teeth with a single root and canal were included in this study. Fifteen teeth were selected as the negative control group to confirm sterilization. Seventy-five teeth were contaminated withEnterococcus faecalis (E. faecalis)for 4 weeks. Teeth were prepared and divided into five groups (n:15): EndoVac, EDDY, EA, SNI and positive control groups. The extruded bacteria were cultured for bacterial quantification. The counts of extruded bacteria were lower in the EndoVac group compared to the EDDY group (P<0.05). The counts of extrusion bacteria were not different in EA and SNI groups compared to EDDY and EndoVac groups (P > 0.05). Within the limits of this study, EndoVac was found to be more reliable irrigation systems than EDDY in terms of the bacterial extrusion.eninfo:eu-repo/semantics/closedAccessBacteriaEndoVacEndoActivatorNeedle IrrigationIrrigation SystemsFive GroupsLetter10.1111/aej.12648492458458358614502-s2.0-85134529667Q2WOS:000828139000001Q4
