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.
