Personal identification based on the radiographic images of the inverted findings of maxillary third molar and supernumerary mesiodens

Abstract

 We report the identification of two unidentified bodies based on the high similarities in abnormal tooth eruption direction. The first case was an extremely rare case of identification by the dental finding of the inverted impacted maxillary third molar. The other was a relatively rare case of identification by the dental finding of the inverted impacted maxillary supernumerary mesiodens. For the two unidentified bodies in one case, it was easy to confirm their identities because the frequency of simultaneous appearance of inverted additional tooth or inverted supernumerary tooth in both was extremely low.
