Dens Invaginatus (DI) is a rare developmental anomaly which affects the tooth, which shows an infolding of enamel and dentine which extends into the pulp chamber and sometimes into the root. The aim of this case report was to describe its radiographic findings, to emphasize the bizarre morphology and the difficulties which are encountered in the diagnosis by using conventional radiographic techniques and the importance of computed tomography as a valuable diagnostic aid. Dens Invaginatus is clinically significant due to the possibility of an early pulpal involvement and the chronic periapical lesions are often associated with this anomaly without any clinical symptoms. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy; therefore, a proper radiologic evaluation by using different imaging modalities, is essential for its successful treatment.
