Aims: To evaluate the volumetric amount of endodontic obturating materials remains after retreatment with and without complementary retreatment(XP-Endo Finisher) utilizing two rotary systems (R-Endo EdgefileXR).Materials Methods: Twenty human mandibular premolars single straight root canals were prepared using a 2Shape system file size 25/0.04. Gutta-percha T-Seal (Epoxy resin sealer) used to o...

INTRODUCTION Gutta-percha must be removed from the root canal space during retreatment to ensure a more favorable outcome. The aim of this study was to compare the efficacy of hand instruments, RaCe and RaCe plus XP-endo finisher instruments in removal of gutta-percha from root canal walls during retreatment. METHODS AND MATERIALS Thirty single-rooted premolars were prepared, obturated, and d...

BACKGROUND The aim was to compare the efficacy of the passive ultrasonic irrigation PUI and the Xp-endo Finisher (FKG-Dentaire, La-Chaux-de-Fonds, Switzerland) in removing the calcium hydroxide paste from root canals and from the apical third. MATERIAL AND METHODS Sixty-eight root canals of single-rooted teeth were shaped using the BT-Race files (FKG-Dentaire, La-Chaux-de-Fonds, Switzerland)....

Objective The aim of this study was to investigate the effectiveness of conventional syringe irrigations, passive ultrasonic irrigation (PUI), Vibringe, CanalBrush, XP-endo Finisher, and laser-activated irrigation (LAI) systems in removing double antibiotic paste (DAP) from root canals. Material and Methods One hundred five extracted single-rooted teeth were instrumented. The roots were split...
