Evaluation of Pressure Distribution against Root Canal Walls of NiTi Rotary Instruments by Finite Element Analysis [PDF]

open access: yesApplied Sciences, 2020
The aim of this study was to evaluate the contact pressure distribution of two different nickel-titanium (NiTi) endodontic rotary instruments against the root canal walls and to virtually predict their centering ability during shaping with finite element

Potential of Operative Torque in Evaluating NiTi Instruments.

open access: yesThe journal of contemporary dental practice, 2020
The role of nickel-titanium (NiTi) in the production of endodontic instruments increased in the last few decades; therefore, the way of evaluation of its performance increased as well. Nowadays, there are several ways to evaluate NiTi instruments, divided into static and dynamic tests.

Endodontic glide path - importance and performance techniques [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2023
Glide path is a procedure that precedes mechanical instrumentation of the root canals. It is defined as a procedure used to expand or create a smooth tunnel from the coronal part of the root canal to its physiological terminus.

The effect of electrical treatment on cyclic fatigue of NiTi instruments. [PDF]

open access: yesScanning, 2014
SummaryDentists desire to use NiTi rotary instruments, which do not break inside the root canals of teeth, since the pieces from broken files are difficult to remove. The NiTi rotary instrument breakage is because of cyclic and torsional fatigue. Here the low‐voltage (12 V) and high voltage (24 V) electrical treatments were used to enhance the cyclic ...

Microstructural and mechanical characterizations of new Ni-Ti endodontic instruments

open access: yesMATEC Web of Conferences, 2015
NiTi alloys have been used for many years in dentistry, especially in endodontology. High flexibility of NiTi alloys, compared to the stainless steel one, has made of NiTi the alloy of choice for the new generation of shaping files.
