In Vivo Evaluation of Operative Torque Generated by Two Nickel-Titanium Rotary Instruments during Root Canal Preparation
Objectives This in vivo study evaluated the operative torque and preparation time of ProTaper NEXT (Dentsply Maillefer; Ballaigues, Switzerland) and EdgeFile X7 (EdgeEn-do; Albuquerque, New Mexico, United States) rotary systems during root canal prepa-ration of...
Torsional resistance of two nickel-titanium rotary instruments: A comparative study
This study explores how heat treatment less significantly influences (increasing or decreasing) torsional resistance when compared to the high increase in flexibility and fatigue resistance reported in many published articles. Moreover, torsional fracture occurs...
