Regional odontodysplasia-an unusual case occurring along with supernumerary teeth

Regional odontodysplasia (RO) is an unusual developmental anomaly which affects the ectodermal and mesodermal component in a group of contiguous teeth. Supernumerary teeth are those that are found in addition to the normal series of teeth. An interesting case of RO, multiple impacted supernumerary teeth and alveolar swelling in the second quadrant is reported here. Unlike the earlier reported cases, the case was unique in that the roots of the hypoplastic teeth showed continued root formation suggesting for more conservative treatment and no cases of simultaneous occurrence of RO and impacted supernumerary teeth have been reported in the literature.
