Mandibular Molar with Six Canals, a Rare Entity: A Case Report.

ABSTRACT

Background: The objective of this report was to highlight the importance of using a dental operating microscope (DOM) to locate supernumerary canals and diagnose variations in root canals using cone-beam computed tomographic (CBCT) images. Case Presentation A 23-year-old male patient had reported with a pain for 1 months and was referred to evaluate symptomatic apical periodontitis for lower right first permanent molar. Root canal therapy was proposed and conducted with the use of DOM and CBCT. Conclusions: Proper diagnosis and careful clinico-radiological examination are necessary, and it is essential to reinforce the knowledge of the rare morphology of root canals for clinicians.
