Root canal retreatment (Re-RCT) cases have shortcomings due to the ineffective removal of the root canal filling material, eventually leading to endodontic failure. This study aims to test the comparative efficacy of retreatment files in removing calcium silicate-based sealer and epoxy resin-based sealer. Thirty-two single-rooted teeth were decoronated at 15 mm and bio-mechanical preparation was performed.

Methods A total of 150 extracted human single-rooted teeth were selected and sectioned into 4 mm slices. The samples were divided into two groups according to the material used: MTA and Biodentine.

- The smear layer negatively impacts the success of root canal treatments by hindering effective sealing during obturation, especially in the apical third where lateral canals are present.
- A study was conducted to compare the effectiveness of various irrigation activation systems (XP Endo Finisher, endoactivator, passive ultrasonic activation, and root canal brush) against conventional irrigation for removing the smear layer while using EDTA and sodium hypochlorite.
- Results indicated that the endoactivator group showed the most significant smear layer removal, followed by passive ultrasonic irrigation, XP Finisher, root canal brush, and conventional irrigation, with all groups exhibiting statistically significant differences.
