Background: The success of endodontic treatment depends on the exploration, proper cleaning, disinfection, and obturation of the entire root canal system. Maxillary first molar is a tooth with wide-ranging root canal configurations. A dental operating microscope provides better visualization of the pulp chamber floor. Cone-beam computed tomography (CBCT) can be used as a good tool for understanding root canal morphology and very few cases were reported using CBCT scanning. Case description: This case repot discusses about a maxillary first molar with three roots and six root canals. Root canal configuration was diagnosed with the aid of a dental operating microscope and confirmed with CBCT. The CBCT axial images showed the Vertucci type II canal pattern in all the three roots. The pulp chamber was modified from conventional triangular access to rhomboidal shape to explore additional canals and root canal preparation was done. Conclusion: The maxillary first molar is a tooth with wide variations in root canal morphology. Use of a dental operating microscope is of great help in such cases and use of CBCT images helps to understand the rare root canal configuration. Clinical significance: A wide range of root canal variations are reported with the first maxillary molar. The use of a dental operating microscope and CBCT helps in better understanding of such variations in root canal configuration. Root canal treatment done with these tools can provide better treatment outcome.
