SURVEY OF CHALLENGES AND MISTAKES IN ROOT CANAL PREPARATION: A STUDY FROM BULGARIA

Aim: The aim of this study is to investigate the challenges and procedural errors encountered by dentists in Bulgaria during root canal preparation.

Materials and methods: An original questionnaire consisting of five questions was developed and distributed at congresses, seminars, and through Microsoft Forms to dentists in Bulgaria regarding their challenges and procedural errors encountered during root canal preparation.

Results: The survey of 213 Bulgarian dentists found that most handle fewer than five primary endodontic cases per week. Common complications include instrument separation (24.9%) and dentinal mud accumulation (24.4%). Trends showed more dentinal mud accumulation with Blue alloys (68.8%) and more ledge formation with Gold alloys (31.4%).

Conclusion:This survey among Bulgarian dentists identified key challenges in root canal preparationwith common complications including instrument separation, dentinal mud accumulation, and ledge formation. These findings emphasize the importance of best practices to minimize errors and improve treatment outcomes.
