Resumo: Dens invaginatus is an anomaly resulting from the enamel organ invagination into the dental papilla. When the invagination is extreme, it can dilate the crown and root, generating a so-called dilated odontoma, rare in the posterior mandible. A 47-year-old female exhibited an asymptomatic radiopaque mass attached to the distal root of the second lower molar, surrounded by a radiolucent halo. Computed tomography scan revealed a hypodense image within the mass. With the hypotheses of fusion, concrescence and odontoma, the tooth and the lesion were removed. After demineralization, the material was hemisectioned, and a cavity within the calcified mass could be seen. Microscopic examination revealed that the mass was composed of tubular dentin, containing a cavity filled with empty clefts and irregular calcified tissue, consistent with the diagnosis of dilated odontoma. The radiological appearance of a dilated odontoma may vary, when the histological analysis is key to the final diagnosis.
