A case of eight impacted supernumerary teeth in the bimaxillary canine and premolar region that occurred symmetrically

Abstract

Impacted supernumerary teeth are frequently found on panoramic X-ray examination and generally arise in the anterior region of the maxilla. Few impacted supernumerary teeth in the canine and premolar region have been reported. Although patients with a genetic disorder sometimes have multiple impacted supernumerary teeth, it is rare for patients without a genetic disorder to have multiple impacted supernumerary teeth. We report a rare case of eight impacted supernumerary teeth in the bimaxillary canine and premolar region that occurred symmetrically in a 16-year-old boy. The number of supernumerary teeth in our patient was eight. We believe that this is the largest number of supernumerary teeth in a Japanese patient without a genetic disorder to be reported.
