The complex anatomy of the root canal system (RCS) creates difficulties in its cleaning and 3D obturation, which is a prerequisite for a number of failures of endodontic treatment.

Aim: This study aims to establish the methods and means of obturation of the RCS, as well as problems related to their use in dental practice.

Materials and methods: An anonymous survey among 157 dentists (LDM) with different age, seniority and location of practice. The questionnaire includes 15 questions, respondents express opinion about the frequency of endodontic treatment difficulties, methods and means of obturation of the RCS.

Results: 30% of respondents held endodontic treatment every day. More than half of respondents state that complex root canal anatomy is the greatest difficulty in processing and obturation of the RCS, the “root canal filling paste with / without gutapercha point” is indicated from more than 60 percent as the most frequently used method of obturation of the RCS and zinc oxide eugenol and formalin-rezortsin root canal filling pastes are still cited by the highest percentage of respondents. 80% of respondents indicate that they need more information about obturation of the RCS.

Conclusions: The results show that the complex clinical and anatomic situation creates difficulties in obturation of the RCS, but most dental practitioners use established in the years methods and means for its obturation.
