Comparison of Knowledge and Awareness of Rotary Endodontics among Dental Interns Studying in Various Colleges in North India: A Questionnaire based Study

Abstract

Introduction: Nickel–titanium (NiTi) rotary instrumentation has transformed root canal therapy by improving efficiency, precision, and clinical outcomes. However, its knowledge and practical adoption among dental interns remain insufficiently explored.

Objectives: To assess the knowledge, awareness, and clinical exposure to rotary endodontics among dental interns studying in government and private dental colleges in North India.

Methods: A structured questionnaire was distributed among dental interns to evaluate theoretical knowledge, training sources, hands-on experience, and confidence in using rotary endodontic systems, including endomotors and apex locators. The data was analyzed using SPSS software (v26.0), with results presented as frequency and percentage.

Results: The study revealed that although most interns demonstrated awareness of rotary endodontic instruments, limited hands-on experience and reduced confidence in using advanced devices were observed, highlighting a discrepancy between theoretical knowledge and clinical training.

Conclusions: The study concludes that there is a need for enhanced, standardized, and clinically oriented training in rotary endodontics to improve intern competence and preparedness for independent practice.
