Dentists' Experience and Knowledge of Rotary Nickel-Titanium Endodontic Systems: A Questionnaire Survey
Abstract: Aim: The aim of this questionnaire survey was to examine the experience, preferences, confidence and skills of Bulgarian dental practitioners in the use of NiTi rotary instruments. Methods: The target group consisted of 650 dental practitioners chosen on a random basis from all Bulgarian administrative districts. They received an online questionnaires consisting of 15 questions via their regional professional organizations. Results: The questionnaire forms were filled and returned by 197 (30.31%) of the respondents, as53.2% of them practicing in the capital and 34%-in the regional cities. About 70% of participants have graduated in the last two decades. Treatment with rotary NiTi files was always preferred by 40.1% of them and very often by 22.8%, with higher rates registered in the capital and regional cities. Half of the respondents had experience in using several rotary NiTi systems with different types of rotation and their choice was dependent on the difficulty of the clinical case. Confidence in the use of NiTi rotary systems was significantly dependent on the year of graduation. About 60% of respondents assessed their skills in using rotary NiTi files as excellent and very good and the satisfaction rate depended on the graduation year. Conclusions: The knowledge and experience in the use of rotary NiTi instruments by Bulgarian dentists is constantly increasing, especially in the capital and regional cities. Younger practitioners, convinced of the benefits of these contemporary systems, feel more confident and ready to introduce them in the daily practice.
