The aim of this case report was to describe its radiographic findings, to emphasize the inexplicable morphology. Considering the likelihood of an early pulpal involvement and the chronic periapical lesions often associated with this anomaly without any clinical symptoms, dens invaginatus is clinically significant. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy. Therefore, a proper diagnosis and evaluation of the anomaly is essential to save the involved tooth.
