The accuracy of two electronic apex locators on effect of preflaring and file size: An study.

Aim: This study was conducted to evaluate the effect of preflaring and file size on the accuracy of the Root ZX and E-PEX Pro electronic apex locators (EALs).

Materials And Methods: The actual working length was set 1 mm short of the apical foramen in the forty extracted mandibular premolars. The teeth were embedded in an alginate mold, and two examiners performed the electronic measurements using #10, #15, and #20 K-files.

Cone-beam computed tomography assessment of root canal transportation using WaveOne Gold and Neoniti single-file systems.

Introduction: The aim of this study was to compare canal transportation of two single-file systems, WaveOne Gold and Neoniti, using cone-beam computed tomography (CBCT).

Methodology: A total of 40 mesiobuccal canals of maxillary first molars with curvatures of 15°-30° were chosen and randomly divided into two experimental groups ( = 20). In both groups, glide path was established using ProGlider.
