Abstract
An additional canal is one of the many anatomical variations that may occur in the root canal system. Comprehensive knowledge of root canal anatomy is a crucial factor in achieving successful endodontic treatment. In mandibular first molars with the possible presence of a fifth canal, careful clinical evaluation, including multiple angulated radiographs, thorough examination of the chamber floor, cone beam computed tomography (CBCT), and other adjunctive aids, can help clinicians prevent endodontic treatment failure. This article describes the endodontic treatment of a mandibular first molar with three canals in the mesial root. The application of CBCT, a dental operating microscope, and several radiographs with different angulations helped effectively identify, prepare, and obturate all five canals, including the middle mesial canal.
