Introduction:
The endodontic treatments have evolved in order to prepare the root canal system to receive a hermetic filling of the system and preserve the health of periapical and/or restore it when affected by tissue injury. These are achieved through obedience the a suitable chemical-mechanical preparation, then the filling of the same.
Objective:
Analyze the chemo-mechanical preparation of root canals performed in vitro by students of Dentistry of the Federal University of Espírito Santo, using the clearing technique.
Material and method:
88 dental specimens (lower canines) were used, and provided to students who performed in vitro preparation chemo-mechanical. These specimens were radiographed and subsequently submitted to leaf clearing technique. The quality of the preparation chemical-mechanical techniques was examined concern the shaping of the root canal and compared the best result of the same, visualized the anatomical features of the root canal system, compared the radiographic exam of the teeth and clearing technique.
Result:
the modeling of root canals analyzed by the clearing technique, 67% were modeled with a statistical significance of 0.002 (p<0.05) and as the concordance of the results of variable modeling of the root canals between the radiographic examination and clearing technique yielded a Kappa value=0.511 showing a moderate agreement between the two visualization techniques.
Conclusion:
The radiography proved to be limited in view of the channel modeling and also in view of the anatomical features of the root canal system, and also that the clearing technique is a visualization technique accessible and essential to the evolution of education in Endodontics.
