Características comuns do odontoma dilatado: uma revisão da literatura por meio da análise de relatos de casos clínicos

Abstract

Invaginated tooth (dens in dente) is a developmental anomaly characterized by the invagination of the enamel organ into the dental papilla. Its most severe form is the dilated odontoma, a rare variant marked by complete invagination and the formation of a hollow structure lined with enamel, dentin, and cementum. This study aimed to review case reports of this condition, highlighting its clinical and radiographic features. A literature review was conducted in the SciELO and PubMed databases, resulting in the selection of 12 articles comprising 13 clinical cases. A predominance in young patients was observed, with a slight male predominance, as well as a higher occurrence in the posterior region of the mandible and the anterior region of the maxilla. The “doughnut-shaped” radiographic pattern was the most frequent. Cone-beam computed tomography proved essential for diagnosis and treatment planning. It is concluded that dilated odontoma presents distinct characteristics, suggesting that it may represent a separate entity.
