Endodontic treatment of maxillary first molar with three canals in mesiobuccal root
using cone beam computerized tomography (CBCT). This case report presents a maxillary
first molar with three mesiobuccal canals. Missing a canal during root canal therapy
is one of the main causes of endodontic failure. The frequency of detection of extra
canals has increased with better techniques in instrumentation, magnification and
illumination. The present case shows three canals in the mesiobuccal root, which is
an aberrant and rare anatomical presentation. CBCT proved to be an important tool
in confirming the presence and location of the extra canals.
