Summary

This case report details an unusual six-canal maxillary first molar. High-magnification microscopy and radiographic re-examination are crucial for identifying extra root canals in molars.

Area of Science:

  • Endodontics
  • Dental Anatomy

Background:

  • Maxillary first molars typically have three or four root canals.
  • Anatomical variations in root canal morphology can complicate endodontic treatment.

Observation:

  • A case of a six-canal maxillary first molar is presented.
  • The canals included mesiobuccal 1 and 2, distobuccal, and three palatal canals.
  • Identification required high magnification (16-25x) using an operating microscope.

Findings:

  • All five initially identified canals (MB1, MB2, Pal1, Pal2, DB) were instrumented and filled.
  • Radiographic examination revealed a missed third palatal canal.
  • This third palatal canal was subsequently located, instrumented, and obturated.

Implications:

  • Clinicians should suspect and meticulously search for additional root canals in molars.
  • Advanced magnification and radiographic techniques are essential for comprehensive root canal detection.
  • Accurate identification and treatment of all canals improve endodontic success rates.
