Regional odontodysplasia: Report of two cases

Abstract

Regional odontodysplasia is a rare localized disorder of tissues of dental origin resulting in characteristically bizarre clinical and radiographic appearances. It most commonly affects the maxillary teeth of both the primary and permanent dentitions. This developmental anomaly is characterized by defective dentin and enamel formation leading to the radiographic appearance of 'ghost teeth' and sometimes by calcifications within the pulp and dental follicle. We report two cases of regional odontodysplasia affecting the maxilla on the right side. In one case, the regional odontodyplasia affected the maxillary left central incisor which is considered to be rare. The pathogenesis, clinical and radiographic features are discussed hereunder.
