Abstract
Anatomical variations in canine dentition, including supernumerary roots, are uncommon but clinically significant, since, among other issues, these structures can accelerate the process of alveolar bone resorption or require a more complex extraction procedure to prevent root fracture. This report describes a rare bilateral occurrence of supernumerary roots in the maxillary third premolars (107 and 207) of a 15-year-old female dog. Radiographic evaluation confirmed three distinct roots per tooth. The teeth were extracted due to severe periodontal disease affecting the supporting structures. This case emphasizes the importance of routine intraoral radiographs in veterinary dentistry for detecting anatomical anomalies and contributes to the understanding of dental variations in dogs.
