AIM: To evaluate the cleaning efficacy of endoactivator, EndoVac (EV), and self-adjusting file (SAF) as irrigant adjunct in the removal of debris from isthmus.

MATERIALS AND METHODS: Forty extracted human mandibular molars were taken. Canals were prepared up to F4 protaper file. Irrigation after each file size was done by 1 ml normal saline. Final irrigation was done by 4 ml of 5% NaOCl and activated in each canal for 1 min with different activating systems. Teeth were divided randomly into 4 groups according to activation system as manual activation (control group, n = 10), Group 2 SAF system (n = 10), Group 3 endoactivator (n = 10), and Group 4 EV (n = 10). After activation final flush was done with 1 ml saline. The mesial root of each tooth was sectioned and checked for isthmus cleanliness by stereomicroscopic analysis. Images were analyzed by ImageJ software. Percentage of debris remaining in each group was calculated.

RESULTS: There is no statistically significant difference in cleaning efficacy of endoactivator, EV, and SAF systems.

CONCLUSION: All three techniques remove debris from isthmus area more efficiently than manual dynamic activation.
