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.
一名13岁男孩前来接受评估，其左上颌侧切牙缺失。在他的上颌中切牙之间的中线处还有一颗形状异常的牙齿。这颗正中多生牙牙根发育不完全。本文讨论了这两种异常情况的罕见关联，认为可能是侧切牙移位到了正中多生牙的位置。
