INTRODUCTION: Fractured rotary nickel-titanium (NiTi) instruments have been classified
into those that fail as a result of cyclic flexural fatigue or torsional failure or a combination of …

Gutmann JL, Gao Y. Alteration in the inherent metallic and surface properties of nickel–
titanium root canal instruments to enhance performance, durability and safety: a focused …

Decontamination of instruments is a prerequisite for their potential reuse but may affect
surface integrity. Hence, the effect of prion removal protocols on 7 brands of nickel-titanium …

This study investigated the effect of immersion in sodium hypochlorite (NaOCl) on torque
and fatigue resistance of two nickel-titanium files. Size 25. 04 ProFile and RaCe files were …

It has been well established over the past 30 years that endodontic disease, the presence of
apical periodontitis, has a microbial pathogenesis. 1, 2 Consequently, root canal treatment is …

Aim To correlate the mechanical behaviour in torsion, bending and fatigue tests of K3
instruments with their dimensional characteristics. Methodology Instrument length, tip angle …

Objective This systematic review/meta-analysis investigated the influence of NaOCl on cyclic
fatigue resistance of endodontic NiTi instruments. Materials and methods A systematic …

OBJECTIVE: The objective of this study was to investigate the trajectory of NiTi rotary
instruments of the same size but different design in an artificial root canal manufactured for …

Aim To evaluate the influence of cyclic torsional loading on the flexural fatigue resistance
and torsional properties of rotary NiTi instruments. Methodology Twelve sets of new K3 …

Introduction Nickel-titanium rotary endodontic files have been commercially available for
decades, but more recent innovations have introduced heat-treated and surface-treated …
