title: Supernumerary tooth in the primary molar region: a case report.
abstract: Supernumerary teeth are among the most common dental anomalies affecting the primary and permanent dentition. They are usually found in the anterior maxilla and occur infrequently in the primary dentition. The purpose of this paper was to report a case diagnosed with primary supernumerary tooth in the primary second molar region. The crown and root shape of the primary supernumerary tooth resembled that of the primary first molar. On radiographic examination, the primary supernumerary tooth was followed by a permanent supernumerary successor with an unusually big crown. The primary supernumerary molar was immediately extracted to avoid interference with the development of the second premolar's tooth bud. This dental anomaly is rarely observed, as only primary supernumerary teeth in the anterior region have been reported in the dental literature.
