This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction:One of the most important steps in endodontic treatment includes the shaping and instrumentation of the root canal system. If not done properly, it may lead to errors including canal transportations and uncentered preparations. Over the last decades, nickel-titanium (NiTi) rotary instruments have enhanced the quality of root canal shaping for clinicians. Currently, two common NiTi rotary instruments, WaveOne Gold and ProTaper Gold, function by two different forms of kinematics: a reciprocating and rotating movement respectively. Currently, preclinical curricula in dental schools do not have a standardized rotary file in which dental students are introduced into endodontics with. This study looks at the use of these two rotary systems by novice sophomore dental students on the quality of their root canal preparations. Purpose: This study aims to examine the influence of kinematics of nickel-titanium instruments (reciprocation vs rotation) on the shaping ability, canal transportation and centering ratio, of novice pre-doctoral sophomore dental students and their preference after its use. Materials and Methods: Forty two identical pre-accessed mandibular left first molar 3-dimensional printed replicas' mesial canals (TrueTeeth; PlanBDental) were instrumented by 21 novice pre-doctoral sophomore dental students. Each canal was previously hand instrumented to a size #15 K file by a single provider. The students were recruited using a random number generator. The teeth were divided up into 2 groups for each rotary file system being used: ProTaper Gold (PTG) (n=21) and WaveOne Gold (WOG) (n=21). Each student instrumented both the mesiobuccal (MB) and mesiolingual canals (ML) using each system. The total instrumentation time was recorded. Micro-computed tomography was used to scan the teeth before and after instrumentation. Centering ratios and canal transportation were calculated at the apical, middle and coronal levels. A questionnaire was completed after instrumentation regarding students' perception with a 5-point Likert scale: ease of use, flexibility, cutting efficiency, screwing effect and overall impression. Conclusion: Compared to a rotation NiTi file system, reciprocation NiTi file system was preferred by novice sophomore dental students, and it also showed less canal transportation and better centering ability with shorter instrumentation times. Future studies are still needed in order to assess if there are further advantages to training novice dental students with reciprocating rotary systems when learning endodontics, but this study can serve as a framework to answer the question.
Download or read book Management of Fractured Endodontic Instruments written by Theodor Lambrianidis and published by Springer. This book was released on 2017-09-28 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This superbly illustrated book provides detailed information on the causes of instrument failure during endodontic treatment, the factors influencing the management of such cases, and the diverse management options that may be employed to resolve the problem. Readers will find clear descriptions and comparative evaluation of the available methods, techniques, and devices. Complications that may arise during the management of fractured instruments are described, and the impact of retained file fragments on the prognosis of endodontic treatment is discussed. In addition, means of preventing iatrogenic errors from occurring in the first place (the best form of management) are explained, emphasizing that the risk of instrument failure is reduced if proper guidelines are carefully considered and followed. The book will assist both endodontists and general dental practitioners in achieving an optimal outcome when confronted with the time-consuming and challenging task of dealing with a fractured instrument within the root canal – a still frequent circumstance despite the plethora of improvements in instrument design, alloy composition, and manufacturing processes.

This book was released on 2006 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Nickel-titanium rotary instruments based upon the intermetallic compound NiTi have gained considerable popularity among endodontists because the very low elastic modulus of NiTi enables these instruments to readily negotiate curved root canals during endodontic therapy with a slow-speed handpiece. However, concern about in vivo separation (fracture) of nickel-titanium instruments during treatment is still a major challenge confronting every manufacturer and endodontist, since this often happens without prior warning signs from permanent deformation. NiTi exists in two major microstructural phases: austenite, and martensite. Transformations between these NiTi phases occur rapidly by twinning on the atomic level and are reversible for stresses below the onset of permanent deformation. An intermediate R-phase is also sometimes observed for the transformation between austenite and martensite. The nickel-titanium rotary instruments are intentionally manufactured in the superelastic condition having the fully austenitic structure, which provides the capability of accommodating extensive elastic strain without fracture under clinical conditions associated with conventional root canal therapy. The overall objective of this study was to gain new insight into the microstructural phases in commercial NiTi rotary instruments and their transformations, which would be of scientific importance for development of new instruments with improved clinical performance. The phases present were identified by Micro-XRD (micro-x-ray diffraction) and TMDSC (temperature-modulated differential scanning calorimetry), using clinically popular ProFile GT and ProTaper nickel-titanium rotary instruments, which have two different cross-sectional designs. Instruments were analyzed in the as-received condition, after clinical use, and following elevated-temperature heat treatments. The first null hypothesis was that microstructural phases and phase transformations do not have an impact on clinical performance and instrument failure. The second null hypothesis was that appropriate heat treatments previously used for orthodontic wires would not result in beneficial changes in microstructural phases that may significantly affect the clinical life of these instruments. Based upon the present research and complimentary previous studies by this investigator, both null hypotheses were rejected. Information obtained from this research should aid future development of improved instruments with reduced likelihood of failure during clinical use.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of nickel-titanium (NiTi) rotary files to endodontics almost two decades ago has changed the way root canal preparations are performed, enabling more complicated root canal systems to be shaped with fewer procedural errors. Currently, a number of rotary Ni-Ti systems are available but it is difficult for dentist to decide which one is better. This book gives a detailed knowledge of various parameters, to evaluate which rotary system has superior shaping ability of the root canals as compared to other. Keeping in view the importance of parameters, each parameter has been described in details i.e. how to measure it and its significance. It also highlights the comparison of shaping ability of root canals with two rotary systems with different designs and their outcome with reasoning
