Materials and Methods: Six real sizes, three-dimensional root models were designed in
SolidWorks software with varying angles of curvature (2–45), and using the same software …

Construction of an accurate 3D model is essential to achieve realistic results using finite
element analysis. In this study the amount of stress expressed on root canal walls during …

The study was aimed to compare the stress distribution during simulated root canal shaping
and to estimate the residual stress thereafter for some nickel-titanium rotary instruments …

Background: The success of root canal treatment and the amount of surviving dentin tissue
around the root canals determine the prognosis of root canal-treated teeth. Stainless steel or …

Introduction Single cross-sectional nickel-titanium (NiTi) rotary instruments during
continuous rotations are subjected to constant and variable stresses depending on the canal …

Construction of an accurate 3D model is essential to achieve realistic results using finite
element analysis. In this study the mechanical behavior of two metallurgically different files …

Nickel-titanium (Ni-Ti) instruments are biologically acceptable, highly flexible and
considerably stronger in fatigue resistance than stainless steel files [1]. Despite these …

This study aims to develop and analyse a finite element model of the endodontic nickel-
titanium (NiTi) instrument during the root canal treatment (RCT). The 3D model of the tooth …

Materials and Methods: Forty resin blocks with simulated canals of 30 curvature were
divided into four experimental groups containing ten samples in each group. The canals …

Aim: Aim of this study is to evaluate the lateral forces on the instrument in the apical 3rd of
curved canal with two Nickel Titanium rotary systems. Methodology: One brand of instrument …
