The effectiveness of endoactivator, EDDY, passive ultrasonic irrigation, and XP-Endo finisher r in removing filling materials from retreated root canals.

ABSTRACT:

Backgrounds

The aim of this study was to evaluate the efficacy of supplementary techniques, including conventional needle irrigation (CNI), EDDY (ED), EndoActivator (EA), passive ultrasonic irrigation (PUI), and XP-Endo Finisher R (XP-FR), in removing residual filling materials from oval-shaped root canals during non-surgical endodontic retreatment.

Methods

Sixty human mandibular premolar teeth were initially prepared using an R25 instrument and filled with gutta-percha points and Bioserra sealer. The initial filling material removal was performed with PTUR D1 (30/0.09) and D2 (25/0.08) files, and the root canals were finally shaped with an R40 instrument. The samples were randomly divided into 5 groups (n = 12) according to the irrigation activation techniques. Residual fil
