Comparison of Canal Transportation and Centering Ability of K-files, ProGlider File, and G-Files: A Micro-Computed Tomography Study of Curved Root Canals

Abstract

Highlights• Micro-CT comparisons of centering ability and apical canal transportation of 3 glide path enlargement techniques in curved root canals of extracted mandibular molars.• K-files were least centered and caused more transportation.• ProGlider displayed superior centering ability.• ProGlider and G-Files caused significantly less transportation than K-files. AbstractIntroduction: The purpose of this study was to compare centering ability and apical
