HISTOLOGICAL EVALUATION OF ROOT CANAL CLEANING AND SHAPING PERFORMED BY UNDERGRADUATE DENTAL STUDENTS USING ROTARY Ni-Ti INSTRUMENTS
Abstract:
The use of rotary instrumentation had gained universal interest, therefore, providing a high level of competence in using these new systems is a major concern of most dental medical schools. This study evaluates the quality of root canal cleaning and shaping achieved by undergraduate students in using rotary Ni-Ti endodontic instruments compared to postgraduate students. We used 60 single rooted extracted teeth, assigned to two study groups that were evaluated based on histological criteria. The presence of debris inside the root canal was assessed and the recordings were statistically evaluated (p<0.05). There was a statistically significant difference between the levels of root canal cleaning and shaping recorded in the study groups. The endodontic performance in using rotary Ni-Ti systems by undergraduate students was not satisfactory, compared to postgraduate students. Therefore, the evaluation of dental curriculum in our school would be necessary in order to improve the undergraduate training in Endodontology.
