ORAL PRESENTATION—CASE REPORT. REGIONAL ODONTODYSPLASIA: A CASE REPORT OF 10-YEAR FOLLOW-UP

Abstract

The present report aims to describe a follow-up presentation of bone sclerosis found in a 6-year-old girl with regional odontodysplasia (RO) and presence of calcifications in a hyperplastic dental follicle (HDF), highlighting their clinical, cone beam computed tomography (CBCT), and histopathologic characteristics. A 16-year-old patient was referred to our service to evaluate the presence of a presumable cystic lesion involving the crown of the tooth #13 and also to evaluate a sclerotic lesion in the right mandible. She had a history of RO, presenting both dentitions with characteristics compatible with “ghost teeth.” The sclerotic lesion was asymptomatic, not expansive, and not related to the RO affected bone, which had 10 years of follow-up. The lesions were submitted to CBCT and histopathologic analysis, rendering the diagnosis of an HDF and idiopathic osteosclerosis. The knowledge of the existence of calcifications in HDF in patients with RO can contribute to the correct identification and diagnosis.
