According to dental literature, the frequency of supernumerary teeth is 1-3%. The authors analyzed the orthopantomograms of 1875 children and adolescents aged between 6 and 18 years to determine the frequency of supernumerary teeth at the Department of Dentistry for Children and Orthodontics. The frequency was found to be 1.92%. The sequence of frequency of supernumerary teeth was: mesiodens, lateral incisor, central incisor. 77.8% of the supernumerary teeth occurred in the maxilla, 97.2% in the frontal region. Besides the data found, two successful cases of surgical and orthodontic treatment are also presented.
