Root canal treatment of Maxillary first molar with multiple root canals.

Vijay Reddy Venumuddala, Sridhar Moturi, S V Satish, B Kalyan Chakravarthy, Sudhakar Malapati

Overview

The permanent maxillary first molar usually has three roots with three canals and the frequent deviation being the incidence of a second mesiobuccal canal. Other variations comprise four, five and six root canals with three to four roots. This varying number of root canals poses a challenge for an 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).

Summary

Missed root canals are the common cause for root canal treatment failure. Conventionally, to assess root canal configuration before, during, and after endodontic treatment, IOPA radiographs play a vital role. However, these radiographs have certain limitations, thus newer diagnostic tools such as CBCT scanning are being used recently, mainly in cases with suspected unusual root canal morphology

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.
