Molarization and development of multiple supernumerary teeth in the premolar region.

This case is the radiological diagnosis of a supernumerary premolar with the molarization of both lower second premolars in a 12-year-old child. Ten years after the diagnosis, the delayed development of another 4 supernumerary premolars was detected. Orthopantomography during mixed dentition allowed the detection of anomalies not clinically suspected. Any alteration in the number of teeth should suggest the potential of associated dental anomalies, indicating the long-term clinical and radiological follow-up of the patient during the second decade of life.
