Patient Complaint: A patient reported pain in the upper right back tooth region. Clinical examination revealed deep Class II caries in tooth 15 (maxillary right second premolar).
Diagnosis: The tooth was diagnosed with Symptomatic Irreversible Pulpitis (SIP). Root canal therapy was advised to save the tooth, followed by a crown.
Treatment Summary:
- After administering local anaesthesia, an access opening was performed.
- During canal exploration, three canals were located
- This is a relatively uncommon anatomy, as most maxillary second premolars typically present with one or two canals.
- Biomechanical preparation (BMP) was done thoroughly using rotary instruments and irrigants.
- Canals were dried, and obturation was done using gutta-percha and sealer.
- Post-endodontic restoration planned with a full-coverage crown.
Why This Case Stood Out:
Maxillary second premolars often show variable root canal configurations. While the classic anatomy includes a single root with one or two canals, clinicians should always be cautious and explore for additional canals, especially with the aid of magnification and CBCT if needed. Missing a canal can lead to persistent infection and treatment failure.
Clinical Takeaway:
Understanding the complex and varied canal anatomy in premolars is crucial for successful endodontic outcomes. Careful access, proper exploration, and the use of modern endodontic tools help in managing such challenging cases effectively.
