This book was released on 2016 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: The third generation of NiTi based rotary files involves a new proprietary thermomechanical process which improves fatigue resistance and flexibility. The purpose of this study was to evaluate the qualitative and quantitative wear/fatigue of three third-generation NiTi rotary endodontic file systems following use in extracted posterior human teeth in a simulated clinical model. Materials and Methods: One hundred files (five packs of five files across four brands: ProFile VortexTM, Vortex BlueTM, ProTaper GoldTM, and Coltene HyFlex® CMTM) were examined with an SEM at the same four positions along their length using a custom-fabricated sample jig before use and through three clinical simulations, and were then evaluated for wear and deformation. Files were categorized as usable, microscopically unacceptable and visually unacceptable. Results: Twelve files visibly failed throughout this study (three separated and eight plastically deformed), and the majority of these failures occurred in the first use of the file. Many instruments were evaluated as microscopically unacceptable before use. A repeated-measures logistic regression analysis found no significant effects for brand, amount of use, and their interaction for files that remained visibly useful. Of those that rated microscopically useful, a significant effect was seen for number of uses (p=0.0127). Contrasts of uses showed significance for use 0 vs. 1, 0 vs. 2, and 0 vs. 3, indicating that unused files were more likely to be microscopically acceptable than used files. No significance was seen between contrasts of uses 1, 2, or 3. Summary and Conclusions: No quantitative wear or distortion pattern specific to any brand was observed that limited multiple file uses. Poor surface condition observed microscopically is not necessarily a precursor to instrument failure. Third-generation controlled memory instruments tend to deform plastically and present minimal risk of clinical separation and canal obstruction through multiple uses.

Available in PDF, EPUB and Kindle. Book excerpt: Rotary endodontic instruments have different cross sectional designs that may effect their resistance to torsional stress. The purpose of this study is to evaluate the static torsional properties of two nickel titanium files that have recently been introduced for use in endodontics and compare them to the same size Profile instruments. Ten new files of each brand and size were tested. The files tested were: RaCe 25 tip 0.02, 0.04, 0.06 taper, K3 and Profile 25 and 40 tip in 0.02, 0.04 and 0.06 taper. The diameter of each file was measured at 3mm from tip. The last three millimeters of the working area of the file was grasped with a non-rotating stainless steel chuck and the handle was held in freely rotating chuck. Torque was applied with the Instron Universal Tester in a counter-clockwise direction to simulate the direction of torque encountered clinically. The crosshead speed was set to produce 2 rotations per minute until fracture occurred. The maximum torque achieved and the rotations to fracture were recorded. A multi-way ANOVA of rotations revealed that RaCe 25-0.02 exhibited significantly less rotations to fracture than Profile and K3 of the same size (p

This book was released on 2012 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The late 1980's witnessed the introduction of superelastic Nickel-Titanium (NiTi)alloy as an endodontic file. NiTi showed superior performance in root canal treatment compared to the conventional Stainless Steel files. After a few years of the use of rotary NiTi files, a greater tendency of fracture was noticed compared to Stainless Steel files, occurring unexpectedly and without previous permanent deformation. Recent research used electro-polished, smooth, triangular-shaped EndoSequence files in smooth glass surrogates of curved tooth-root canals, demonstrating extended times to file fracture during rotational bending at 300 rpm when the files were pre-coated with low-Critical Surface Tension (CST) silanes or lubricated in low-surface-tension surfactant solutions. A common feature was NiTi file fracture at a Surface Strain Amplitude of 3-4%, indicating that reduction of surface friction was by delay of surface crack opening. Earlier failure in NaOCl (bleach) lubricant was noted.^That prior work tested files held at stepped, static locations in curved glass tubes. The aim of this follow-up research was to further evaluate the cyclic fatigue resistance of rough-surfaced, triple-U-shaped Protaper® endodontic files, operated in more clinically relevant up/down filing motion, when their surface character also was modified through coating the files with two types of silanes, as "dry" lubricants. The first coating was Octadecylsilane (ODS) and the second was (3-Hepta-fluoroisopropoxy)propylsilane (3-HEPT). The cyclic fatigue of untreated control files and surface-modified files was tested dry and with five different irrigation solutions, some of which are commonly used in endodontic treatment. The irrigants used were distilled water, 5% sodium hypochlorite NaOCl, 17% ethylenediaminetetraacetic acid (EDTA), Surface Active Displacement Solution (SADS; an emulsion of water, butanol, and a surfactant), and Delmopinol (an aqueous solution of an aminoalcohol surfactant).^Bent glass tubes simulated curved root canals, in which an AEU-20 Endodontic System ITR motor rotated files at 300 RPM and high torque. More than 300 samples were tested in this research. After testing, the files were viewed under the scanning electron microscope to evaluate the fractured area, and it was shown that all the tested files showed signs of abrasion on the edges of the fractured areas. Analysis of Variance (one way ANOVA) and Multivariate Tests were the main statistical methods to compare the number of cycles to fatigue fracture (NCF). NCF of the coated files was significantly higher than for files tested as received F (2,321)=6. 887, P=0. 001. When sodium hypochlorite was used as an irrigant, the files demonstrated the shortest fatigue life in the 45o bent glass tube due to high friction and corrosion of the nickel when the applied stresses were above the critical stress for martensite transformation.^When low-surface-tension irrigants (SADS and Delmopinol) were used, the files demonstrated the longest fatigue life in the 45 o bent glass tube due to better lubrication and friction reduction. It was confirmed that NiTi file failure occurs at mean surface strain values of 3-4%, irrespective of surface finish or degree of file curvature. Number of cycles to failure is significantly increased in the presence of surface-energy-reducing substances, both as coatings and as lubricants, separately or in combination. Failure is accelerated by corrosive attack of NaOCl (bleach) during rotational bending producing tensile-compressive transitions from the austenitic to martensitic atomic structures. Even in this latter case, reduction of crack-opening surface friction is the proposed beneficial mechanism.
