Endodontic Management of a Maxillary First Molar with Seven Root Canal Systems Evaluated Using Cone-Beam Computed Tomography Scanning.

Permanent maxillary first molar morphology has been studied widely. Usually, it has three roots with three canals and the frequent deviation being incidence of a second mesiobuccal canal, thus showing a multifaceted root canal anatomy. Other variations comprise four and five roots and abnormal root canal morphology within individual roots.
