Maxillary second premolars rarely have three canals, but this possibility is crucial for endodontic treatment success. Recognizing this anatomy can prevent ongoing postoperative discomfort and ensure proper root canal therapy.

Area of Science:

  • Dentistry
  • Endodontics
  • Dental Anatomy

Background:

  • Maxillary second premolars typically present with one or two root canals.
  • Anatomical variations in root canal systems can complicate endodontic procedures.

Observation:

  • The presence of three canals in a maxillary second premolar is uncommon.
  • Such anatomical variations may not be detected during initial clinical and radiographic assessments.

Findings:

  • This case report details the endodontic treatment of maxillary second premolars with three canals.
  • Delayed diagnosis of the third canal can lead to persistent postoperative endodontic discomfort.

Implications:

  • Awareness of potential three-canal systems in maxillary second premolars is vital for endodontic diagnosis and treatment planning.
