title: [Case report of three impacted supernumerary teeth in the premaxillary region].
abstract: A case is presented of a six-year-six-month-old boy with three impacted supernumerary teeth in the premaxillary region. The radiographic examination showed one mesiodens resorbing the root of the left primary central incisor and two inverted supernumerary teeth, also displacement of the unerupted permanent central incisors. Surgical treatment was performed to remove these supernumerary teeth. The forms of the mesiodens exhibited tubercularly shaped crown with four-conical cusp and two inverted supernumerary teeth showed a conicalshaped crown with incomplete root. According to the family history, a sibling had a supernumerary tooth in the same region which had been extracted in the past.
