Introduction Root canal treatment is one of the most technically challenging procedures in dentistry and the success depends on the diagnos- tic acumen, instruments used and the technologies adopted. The adoption of endodontic nickel-titanium rotary technology by en- dodontists in India has increased two folds in the last two decades. Dental caries are easily detectable and reversible at an early stage. The management of such a condition calls for a comprehensive approach to identifying the cause and treating it.[1]. Although all endodontists use rotary technology there is a signifcant disparity in the different systems used, frequency of use and the methods of use [2]. A survey was conducted to understand the usage of rotary instruments by endodontists in Chennai ,India. Endodontic treatment encompasses procedures that are designed to maintain the health of all or part of the pulp[3] . When the pulp is diseased or injured, treatment is aimed at preserving nor- mal periradicular tissues. Root canal treatment is done when caries have spread the infection to the periradicular region[4] . Cleaning and shaping of the root canal system is one of the main goals in endodontics which can be carried out using different sys- tems and techniques[5]. Traditionally, stainless steel used in the manufacturing of hand instruments for root canal shaping lacks fexibility with increasing sizes and can lead to procedural errors[6] resulting in a decreased success rate for endodontic treatment [7]. In 1988, root canal instruments manufactured from nickel-titani- um (NiTi) alloy were introduced to overcome the rigidity of stain- less steel [8]. NiTi is one of several shape memory alloys, but this particular alloy of two metals has the most important particular applications in medicine and dentistry due to its biocompatibility and corrosion resistance[5]. NiTi alloy was discovered by Buehler HM et al., and named Nitinol which stands for nickel, titanium, Naval Ordnance Laboratory [9]. In endodontics, NiTi was initially reported for use by Walia HM et al., [9]. Rotary instruments, especially nickel titanium ones, have the ad- vantage of instrumentation with reduced errors during treatment. Abstract The preference and usage of nickel titanium rotary instruments varies from individual to individual based on their technique, experience with the rotary systems and the clinical situation. Very limited information is available to explain the adoption of changing concepts with respect to nickel titanium rotary instruments pertaining to the endodontists in India.This is a comparative and descriptive study for which the data was obtained from the responses given by the participants of a survey circulated through an online platform. The data collection was from the dental practitioners, Endodontists, and post gradu- ates in Tamilnadu. The data was collected and compiled followed by its statistical analysis by using the SPSS software by IBM. The aim of this study was to conduct a questionnaire survey to acquire the reuse of rotary systems by dental practitioners, Endodontists, and post graduates.
