Background: Mandibular canines are usually single-rooted with a single canal, making them among the most morphologically stable teeth. The occurrence of a two-rooted mandibular canine is an extremely rare anatomical variation, reported in less than 5% of cases in Asian populations. Such variations can complicate diagnosis and endodontic treatment if not identified early.

Case Presentation: This report describes the endodontic management of a mandibular canine with two distinct roots. The patient wanted fixed partial denture so intentional RCT was planned with respect to lower canine. Clinical examination and initial periapical radiographs suggested unusual root morphology. Angled radiographs confirmed the presence of two roots with separate canals. Endodontic treatment was performed under magnification, with careful biomechanical preparation and obturation of both canals.

Discussion: The presence of additional roots or canals in mandibular canines, though rare, has been documented in literature. Missed roots can compromise endodontic outcomes, leading to persistent pathology. Advanced diagnostic tools such as CBCT, coupled with the use of magnification and modern endodontic armamentarium, significantly improve the ability to detect and manage such variations. This case reinforces the importance of considering anatomical anomalies during routine treatment planning.
