Identification of root canals in maxillary molars using cone beam computed tomography

Resumo

Introduction: Knowledge on variations in the root canal system is
essential for a successful endodontic treatment. Objective: To present
a case of identification of root canals in the maxillary left first molar,
including the fourth root canal in the mesiobuccal root, using cone
beam computed tomography (CBCT). Conclusion: The CBCT system
proved to be relevant in providing important information on the root
canal system for the planning of endodontic treatment in cases of
persistent infection or access difficulties.
