Aim: This ex vivo study was designed to evaluate and compare different endodontic irrigation and activation systems, the self-adjusting file (SAF) instrumentation/irrigation system, and XP-endo finisher for removal of intracanal smear layer.
Materials And Methods: Fifty recently extracted, noncarious human intact single-rooted premolars were selected and divided into five groups ( = 10) according to the root canal irrigation systems; syringe and needle irrigation, passive ultrasonic irrigation (PUI), EndoVac irrigation system, SAF system, and XP-endo finisher. All groups were prepared to apical size F4 file except for the SAF group which was prepared to apical size 20 K-file and then instrumented with the SAF file.
This study aimed to evaluate the efficacy of ProTaper, Mtwo, and WaveOne retreatment files and Hedstrom files for removal of gutta-percha from the straight root canals using cone-beam computed tomography (CBCT). Forty freshly extracted single-rooted and single-canal teeth were selected for this study. The teeth were decoronated, and biomechanical preparation was performed up to #30 K-file.

Materials And Methods: Thirty-five premolars were divided into three experimental groups (n = 10) and a control (n = 5): (1) CI, (2) CI plus sonic activation (EndoActivator), (3) CI plus ultrasonic activation (EndoUltra), or (4) CI using saline. All teeth were prepared to a size #40 K file.
Introduction: This study was designed to evaluate and compare different endodontic irrigation and activation systems for removal of the intracanal smear layer.
Methods And Materials: Forty recently extracted, non-carious human intact single rooted premolars were selected and divided into five groups (=10) according to the root canal irrigation systems; syringe and needle irrigation (CTR), sonic irrigation, passive ultrasonic irrigation (PUI) and EndoVac irrigation system. All groups were prepared to #40 apical size with K-files.
