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. Many case reports with five and six root canals or a C-shaped canal configuration have been reported in the past. This varying number of root canals poses a challenge for endodontist in detecting and treating by root canal treatment. This problem can be avoided using techniques such as using the dental operating microscope and cone-beam computed tomography (CBCT). We report a change in canal morphology case of maxillary first molar having seven root canals, its evaluation, and management using latest equipment such as CBCT.

Endodontic management of mandibular first molar with middle distal canal: a case report.

The knowledge of variations in root canal morphology is critical for a successful endodontic treatment. This article presents the endodontic management of a unique case of mandibular molar with middle distal canal which is quite uncommon.
