Percepção de acadêmicos do curso de odontologia em São Luís acerca da instrumentação mecanizada em endodontia

Abstract

The mechanical chemical preparation of the root canal system plays an essential role in endodontic therapy, as it facilitates cleaning, disinfection and shaping of the canal, preparing it later for the filling stage. Although the biological goals of treatment have not changed over the years, the methods to achieve these goals, in turn, have changed with the introduction of mechanized systems, raising a series of discussions about their advantages and disadvantages when compared to manual technique. In this context, verifying if there is greater ease and safety in the use of the mechanized

technique in endodontics is essential to analyze the impact of mechanized nickel- titanium (NiTi) instruments in clinical practice during graduation. The present study is

a descriptive experimental research, which aimed to evaluate the perceptions of academics from the 4th to the 5th year of dentistry at a University Center in São Luís - MA, about mechanized instrumentation in endodontics, checking whether this has a positive impact during the endodontic treatments performed by them at the school clinic. A questionnaire was formulated on the Google Forms platform, with 16 objective questions and it was filled out using an electronic device. After its application, data tabulation in Microsoft Office Excel and use of descriptive statistics, it was concluded that mechanized instrumentation in endodontics has a positive impact when performed by undergraduate students. It was also noticed that the Reciproc system was the most used by most students (83.30%) and that most students considered that mechanized instrumentation in endodontics optimizes working time and operative steps (100%) , offers better comfort to the patient (96.7%) and the operator (90.0%), in addition to facilitating the filling stage (80.0%).
