The implementation of rotary systems in endodontics

The use of NiTi rotary instruments in Endodontics increased the quality of endodontic treatments and reduced the number of errors during root canal preparation. There are few papers in Brazil and around the world analyzing the diffusion of this new technology. The aim of this study involving Brazilian dentists was analyzed the accept of the new technologic in Endodontics. The increased purchasing of this new technology does not necessarily lead to correct use and incorporation into practice. A questionnaire survey comprising 16 questions was sent to 250 students and endodontics’s e-mails. The sampling frame was 108, comprising 71% specialists and 26% postgraduate students. Rotary instruments were used by 88%, 55% of them used rotary and alternated rotation system and 41% only rotary instrumentation. Fracture and the high cost of the instruments were the main reasons for not using rotary NiTi in endodontics.
