| dc.description.abstract | Knowledge of the anatomy of the intricate and complex root canal system of each tooth group is of utmost importance for dental practice, it constitutes one of the cornerstones for the success of endodontic treatment along with the diagnosis, chemomechanical preparation and obturation. Hence, it is appropriate to conduct studies on anatomical diversity of the root canal system of lower incisors, cataloged according to many professionals as having just one root canal.
Various techniques have been employed to study the root canal system of lower incisors, however clearing technique by which one can get a dental tissue clearance is one of the most used and a very didactic teaching method at the same time, because it allows to obtain translucent tooth root canals and possible anatomic variants pigmented, making possible a 3D visualization of the complex root canal system.
In the present investigation 143 lower incisors were cleared, in order to describe their internal anatomy and to get information from our own environment as well, which can be useful for students and professionals working in the endodontic field. The results showed that 89.5% of the incisors had a type I canal, 1.4% type II, 2,1 % type III, 1.4% type IV, 4.2% type V and 0.7% type VII. The incidence of lateral canals and deltas was 37,8% and 15,73, respectively | |
