Regional odontodysplasia
Classification and external resources
ICD-10	K00.4
ICD-9	520.4

Regional odontodysplasia is an uncommon developmental abnormality of teeth, usually localized to a certain area and nonhereditary. No predilection for race, but females are more likely to get regional odontodysplasia. The enamel, dentin, and pulp of teeth are affected, and on radiographs the teeth are described as "ghost teeth". ^[1] Most cases are considered idopathic but some cases are associated with syndromes, growth abnormalities, neural disorders, and vascular malformations. Permanent teeth usually show effects of regional odontodysplasia if the deciduous tooth was affected. Many of these teeth don't erupt with an increased risk for caries and periapical inflammation.

Treatment/Prognosis is usually based upon keeping these teeth and preserving the alveolus. For erupted teeth, Endodontics is an option if the tooth is devitalized and restorable. For unerupted teeth, function can be restored with a removable partial denture until all major growth has been completed and a final restoration can be placed. ^[2]
