It may affect either a single tooth or several teeth. The term regional odontodysplasia is used if several teeth are affected. It affects the deciduous and permanent dentitions in the maxilla, the mandible or both, although the maxilla is more frequently involved. A type of dental dysplasia occurring in dentinogenesis imperfecta in which the pulp chambers are enlarged and there is a reduced amount of coronal dentin.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
