C-shaped canal in maxillary first molars: a case report

Area of Science:

• Endodontics
• Dental Anatomy
• Radiology

Background:

• C-shaped root canal configurations are uncommon in maxillary first molars.
• This anatomical variation presents diagnostic and treatment challenges.

Observation:

• A rare case of bilateral C-shaped maxillary first molars was identified.
• Spiral computed tomography (CT) and dentascan were used for detailed morphological analysis.

Findings:

• The C-shaped configuration was classified as Melton category I.
• Fused roots were observed in conjunction with the C-shaped canals.
• Detailed internal and external root morphology was elucidated via advanced imaging.

Implications:

• Accurate diagnosis of C-shaped canals is crucial for successful endodontic treatment.
• Advanced imaging modalities like spiral CT are vital for understanding complex root anatomy.
• This case contributes to the understanding of rare maxillary molar morphology and its clinical management.
