Knowledge, attitude, and practice of ultrasonics in endodontic treatment

Abstract

The use of ultrasonics (US) has greatly expanded in the field of dentistry. Over the past few decades, the application of US has increased substantially in endodontics owing to the predictable prognosis and ease of operation. The objective of this survey was to determine the knowledge, practice, and attitude of US in endodontics among the general practitioners, postgraduates, and endodontists. An electronic questionnaire containing 16 questions regarding the knowledge, attitude, and practice of US in endodontics was circulated among the general dentists, postgraduates, and endodontists and the responses were collected online. Data were statistically examined using IBM SPSS software. A total of 202 dentists (general dentists = 92, endodontists = 77, and postgraduates = 33) participated in the survey. Eighty-nine percent of them were aware of the use of US in endodontics, 36.1% of them preferred using US in the removal of pulp chamber calcifications, pulp stones, access refinement, and troughing hidden canals, and 61.4% chose <3% sodium hypochlorite for root canal irrigation with US. The cost of the ultrasonic unit and heat generation during procedures were considered the greatest limitation in using the US. The majority of the dentists were well aware of the use of US and its advantages in various endodontic procedures but they did not use it routinely in their practice. The use of US has been reported to have greatly increased the predictability of endodontic treatment.
