Cyclic Fatigue Fracture Resistance of Newer Rotary Files

This study employed two approaches for measuring time of file fracture - direct visualisation and also watching a filmed video clip in comparison to other studies that used on direct visualisation. Numerous elements, such as rotational speed, metal surface treatments, multiple autoclaving, and metallurgical characterization of the Ni-Ti alloys, may influence the fatigue resistance of Ni-Ti rotary files. The dentist controls the axial movement of the endomotor handpiece manually. Because these variables were not repeated in this in vitro study, additional In vivo studies are necessary to verify the findings of the current study.
