Summary

This study reports rare C-shaped root canal systems in maxillary first molars, a finding typically seen in mandibular molars. Anatomical analysis suggests this anomaly results from root fusion.

Area of Science:

  • Endodontic dentistry
  • Dental anatomy
  • Root canal morphology

Background:

  • C-shaped root canal systems are uncommon dental anomalies.
  • They are most frequently reported in mandibular second molars.
  • Maxillary first molar C-shaped canals are exceptionally rare, with limited case reports.

Observation:

  • Two cases of C-shaped root canal systems in maxillary first molars were identified.
  • These were found during endodontic treatment of 2175 maxillary first molars.
  • Anatomical cross-sections of two additional molars visualized the C-shape.

Findings:

  • The C-shaped canal configuration in these maxillary first molars resulted from the fusion of the distobuccal and palatal roots.
  • This anatomical variation presents unique endodontic challenges.

Implications:

  • Increased awareness of this maxillary molar anomaly is crucial for endodontic success.
  • Detailed anatomical understanding aids in diagnosing and treating complex root canal systems.
  • Further research into the prevalence and etiology of C-shaped canals in maxillary molars is warranted.
