Abstract:
A rare case of radicular dens invaginatus (dens in dente) was found during dental cleaning of a 5-year-old male Rottweiler dog. Radiographic examination revealed intense radiopacity, which extended from the crown to the apical root region of the affected tooth. Macroscopically, the crown of the left maxillary first molar tooth (209) had irregular and deformed buccal and lingual surfaces. Microscopic examination revealed dentine invagination in the pulp cavity in of the crown and root and pulp necrosis. Based on the gross, radiographic and histological findings, a diagnosis of radicular dens invaginatus was made.
