Abstract
Regional odontodysplasia (RO) is a rare developmental dental anomaly with a prevalence of less than 1 in 1,000,000 in humans. The main objective of the present work is to present imaging aspects of RO. A 13-year-old female patient was referred to the radiology clinic for panoramic radiography and cone beam computed tomography. In these examinations all the teeth in the left maxilla and the tooth 11 showed alteration in size and shape of the crown and root. The affected teeth had the appearance of ghost teeth, with a reduction in enamel thickness and density in addition to large pulp chambers and open apices. Usually, the teeth presented developmental delay and eruption in relation to the corresponding ones on the contralateral side. The alterations identified in the imaging tests suggest a diagnosis of RO. The proposed treatment was conservative until the period of bone maturation.
