Abstract
Mandibular second premolars pose a considerable challenge in endodontic therapy due to the complex and highly variable nature of their root canal morphology. Failure to recognize atypical anatomical configurations can result in untreated canals and subsequent treatment failure. This case report describes a rare instance of a mandibular second premolar exhibiting two separate roots and four distinct root canals. Additionally, an iatrogenic perforation on the distal crown surface occurred during access cavity preparation. The tooth anomaly was accurately diagnosed and successfully managed using cone-beam computed tomography (CBCT), which facilitated precise identification of canal anatomy and guided appropriate endodontic and perforation repair procedures.
