Abstract

Odontodysplasia is an uncommon clinicopathological condition with a variety of expressions. Although it is generally recognized as a localized disorder of dental tissue, its aetiology has not yet been well explained. In the present case, odontodysplasia with oligodontia in the permanent dentition is reported. The patient was in good health with normal stature and no other physical abnormalities. His parents and siblings were dentally and medically normal. The primary teeth appeared to be normal except for the primary second molars, where the enamel was malformed. However, the permanent incisors that had erupted into the oral cavity showed rough and hypoplastic enamel. An orthopantomogram showed 17 congenitally missing permanent teeth and malformation of the other 11 permanent teeth and tooth-germs. Because these findings were caused by developmental disturbances of both the mesodermal and ectodermal dental components, we diagnosed the present case as odontodysplasia accompanied by oligodontia in the permanent dentition.
