Regional odontodysplasia

Regional odontodysplasia is an uncommon developmental abnormality (Source?) of teeth, usually localized to a certain area and nonhereditary. There is 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 idiopathic, 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 do not erupt with an increased risk for caries and periapical inflammation.

Treatment and prognosis

Treatment and prognosis are 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]
