Unusual position of impacted mesiodens

Abstract

The term ‘supernumerary’ defines teeth that form additionally to the normal dentition. It can be found anywhere in the dental arch. A mesiodens is a supernumerary tooth located between the two maxillary central incisors, usually palatally or within the alveolar process. Less frequently, the mesiodens is in relation to the nasal floor and the nasopalatine canal walls. The paper reviews and presents three case reports with rare locations of impacted mesiodens which were found incidentally during Cone Beam Computed Tomography (CBCT) evaluation for endodontic purposes..
