Opto-Magnetic Imaging Spectroscopy in Analyzing Rotary NiTi Endodontic Instruments

Journal of the Mechanical Behavior of Biomedical Materials, 2023
Intra-canal fracture of rotary NiTi instruments occurs due to torsional stress, cyclic fatigue, or a combination of these two factors. Broken instruments are a serious obstacle to shaping, cleaning, and filling of the root canal and can adversely affect ...

Effect of Flexural Stress on Torsional Resistance of NiTi Instruments

Journal of Endodontics, 2021
Previously published studies have deeply investigated the characteristics of flexural and torsional resistance of nickel-titanium rotary instruments, but none of them investigated the relationship between the 2 stresses. The objective of the present study was to evaluate the influence of flexural stresses over torsional resistance.Sixty S-One 20.04 ...

Rotary NiTi Instrument Fracture and Its Consequences

Journal of Endodontics, 2006
The fracture of endodontic instruments is a procedural problem creating a major obstacle to normally routine therapy. With the advent of rotary nickel-titanium (NiTi) instruments this issue seems to have assumed such prominence as to be a considerable hindrance to the adoption of this major technical advancement.
