title: Concomitant hypohyperdontia: simultaneous occurrence of a mesiodens and agenesis of a maxillary lateral incisor.
abstract: A 13-year-old boy appeared for evaluation with a missing maxillary left lateral incisor. He also had an abnormally shaped tooth in the midline between his maxillary central incisors. This mesiodens had an incompletely developed root. The unusual association of these 2 anomalies is discussed as a possible transposition of the lateral incisor to the mesiodens position.
