title: Regional odontodysplasia.
abstract: A case of regional odontodysplasia is reported. An unusual feature, only twice previously described in the world literature of fifty-four cases, was the presence of an apparently normal tooth within the group of affectd teeth. The implications of such a finding for the various theories relating to aetiology and pathogenesis are discussed.
