Evaluation of the anatomical alterations of lower molars mesial root’s apical third

Avaliação das alterações anatômicas do terço apical da raiz mesial de molares inferiores

The anatomical apex of the mesial root of the lower molars presents a morphological complexity related to the number and shape of the root canals as well as of the apical foramen and isthmus presence. The knowledge of the complexity of the endodontic system of the molar root area is essencial to select more carefully the best instrumentation and obturation technique, to obtain a more successful endodontic therapy.
