Dens invaginatus in an impacted mesiodens: a morphological study.

Author information

Department of Oral Pathology, Faculty of Dentistry, National University of Cordoba, Argentina;


Dens invaginatus (DI) is a dental anomaly originated from invagination of the enamel organ into the dental papilla, during odontogenesis. DI may be associated with other abnormalities such as dysmorphic mesiodens, and this unusual condition may be detected by chance on the conventional radiography. However, the three-dimensional nature and the exact morphological patterns of DI are impossible to appreciate from this method. We present a morphological study of impacted mesiodens in a 9-year-old girl, which the three coronal invaginations were detected only by Cone-Beam Computed Tomography (CBCT) in the pre-surgical examination. CBCT, radiographic and microscopic reproductions allow transfer of images to facilitate cooperation of working groups, examination as well as for teaching purposes.
