A cleaning protocol for rotary nickel-titanium endodontic instruments

A cleaning protocol for rotary nickel-titanium endodontic instruments.

BACKGROUND The cleaning of endodontic and all dental instruments prior to sterilization is a prerequisite for their processing for re-use. This study aimed to develop a clinically practical cleaning protocol for rotary nickel-titanium (NiTi) endodontic files prior to sterilization. METHODS Cleaning experiments were conducted on six different types of files that had been used on human teeth. T...

Fracture resistance of electropolished rotary nickel-titanium endodontic instruments.

The purpose of this study was to investigate the effect of electropolishing on cyclic flexural fatigue and torsional strength of rotary nickel-titanium endodontic instruments. Electropolished and nonelectropolished ISO size 30 (0.04 taper) EndoWave (J Morita Corporation, Osaka, Japan), ProFile (Dentsply Maillefer, Ballaigues, Switzerland), and RaCe (FKG, La-Chaux De Fonds, Switzerland) instrume...

Endodontic rotary nickel-titanium instrument systems.PDF

Since the end of the nineteenth century, automated root canal instrumentation has been available, but systems had many problems. The challenges of increased canal blockage, instrument breakage, and insufficient canal debridement were related to the use of stainless steel instruments and have been dramatically improved with the introduction of nickel-titanium (NiTi) files. The first useable NiTi...

An Investigation of Phase Transformation Mechanisms for Nickel-titanium Rotary Endodontic Instruments Dissertation

Mechanical behaviour of nickel-titanium rotary endodontic instruments in simulated clinical conditions: a computational study.

AIM To develop an accurate finite element (FE) model for studying rotary endodontic instruments and to demonstrate the usefulness of the FE method in improving the knowledge of the mechanical behaviour of these instruments during root canal preparation. METHODOLOGY An accurate geometrical model of a Ni-Ti ProTaper F1 instrument was created. The interaction between the rotating instrument and ...
