Abstract:
ABSTRACT In the last decade, nickel-titanium (NiTi) rotary canal instruments have proved to be valuable for root canal therapy because of their exceptional ability to shape root canals with potentially fewer procedural complications. The purpose of this clinical update article is to bring clinicians up to date with the current and popular endodontic rotary NiTi instrument systems.

Objective: To evaluate the effect of synchronous water irrigation on the fatigue resistance of nickel-titanium instrument. Methods: A standardized cyclic fatigue test models were established, and five types of nickel-titanium instruments (PTU F1, WO, WOG, RE, and M3) were applied. Each instrument was randomly divided into two groups ( N = 12). There was synchronous water irrigation in the experimental group, and no water irrigation in the control group. Besides, ProTaper Universal F1 was randomly divided into 10 groups ( N = 20). In the static group, nickel-titanium instruments were divided in

A large number of engine-driven NiTi shaping instruments already exists on the market and newer generations are being introduced regularly. While emphasis is being put on design and technique, manufacturers are more discreet about alloy characteristics that dictate instrument behavior. Along with design and technique, alloy characteristics of endodontic instruments is one of the main variables affecting clinical performance. Modification in NiTi alloys

Introduction. Active parts and tips of various new stainless steel and nickel-titanium endodontic instruments can be coated with fragments or metal residues, which can become detached during endodontic treatment. These fragments may obstruct the root canals or even reach the periapical tissue during biomechanical preparation and should be removed before clinical use. Objective. The aim of this study was to evaluate the presence of metal residues on both new stainless steel and nickel-titanium endodontic instruments, and to determine the cleaning efficacy of ultrasound using distilled water or

Summary Introduction Separation (fracture) of endodontic instruments in the root canal during chemomechanical instrumentation is a complication that can compromise the final outcome of endodontic treatment. One of the most common factors that cause fatigue of endodontic instruments and consequent fracture is surface corrosion. The aim of this study was to investigate the ultrastructure of surface corrosion of endodontic instruments made of stainless steel and nickel-titanium after immersion in the most commonly used root canal irrigants.

Abstract:
Root canal preparation in narrow, curved canals is a challenge even for experienced endodontists. Recently nickel-titanium (NiTi) hand files have played an important role in root canal preparation, particularly in curved root canals. Nickel-titanium endodontic instruments were first investigated in 1988 by Walia et al. who found that NiTi files have two to three times more elastic flexibility in bending and torsion, as well as superior resistance to torsional fracture compared with similar stainless steel files.

Abstract Introduction: This study was undertaken to understand how fatigue affects the torsional properties of both traditional nickel-titanium (NiTi) and nickel-titanium controlled memory (CM) files. Methods: Typhoon (TYP) 25.04 and 40.04 rotary files, in both NiTi and CM, were tested using a three-point bending apparatus to obtain the mean number of cycles to failure (mNCF). New files were precycled to four conditions (i.e., 0%, 25%, 50%, and 75% of the mNCF) before torsional resistance tests were performed. Each file was exposed to torsional stress until failure, and at that point the to

The mechanical behavior of a rotary nickel-titanium endodontic instrument was evaluated through finite element models. Essential geometric features of blank taper and variable pitch were modeled and their impact on the mechanical performance of instruments was investigated. Simulation results showed that better bending flexibility and higher torsional stiffness can both be obtained on an instrument with a large helix configuration. The results also illustrated that the finite element method can be used to compute the critical load or deformation for the instrument which prompts the sustainable

Direct Metal Laser Sintering (DMLS) is an additive manufacturing technology that can construct medium to small size parts very efficiently in comparison to traditional machining processes. The ability of this technology to grow complex parts made of high strength titanium- and nickel-based alloys led to increasing interest from aerospace, defense, and medical industries. Although the technology allows growing parts close to their final shape, the active surfaces still need a finishing operation such as grinding to meet the tight tolerances and surface finish requirements.
