Maxillary impacted mesiodens are frequently encountered in pediatric dentistry. Much research has been conducted concerning their incidence, position, and form. Supernumerary teeth erupting in the primary dentition with maxillary impacted mesiodens are very rare. In January 2011, a nine-year-old boy presented for dental treatment and was found to have supernumerary deciduous teeth. Upon panoramic radiography, multiple impacted mesiodens were found; therefore, computed tomography (CT) was performed for further examination. One month later, the boy was referred to our department for extraction of the deciduous supernumeraries and impacted mesiodens. We suspected that these supernumeraries, mesiodens, and remaining primary teeth would lead to problems with the eruption of the permanent teeth. Therefore, by ascertaining the exact position of the mesiodens and the successional permanent teeth using CT, extraction was performed under general anesthesia in March 2011 without any error. Six months postoperatively, panoramic radiographs showed no superfluous structure that appeared to be a tooth. We suggest that when multiple maxillary impacted mesiodens are found, their exact positions can be located using CT before extraction.
