Unusually large erupted complex odontoma: A rare case report

Shivanand B Bagewadi et al. Imaging Sci Dent. 2015 Mar.

Abstract

Odontomas are nonaggressive, hamartomatous developmental malformations composed of mature tooth substances and may be compound or complex depending on the extent of morphodifferentiation or on their resemblance to normal teeth. Among them, complex odontomas are relatively rare tumors. They are usually asymptomatic in nature. Occasionally, these tumors become large, causing bone expansion followed by facial asymmetry. Odontoma eruptions are uncommon, and thus far, very few cases of erupted complex odontomas have been reported in the literature. Here, we report the case of an unusually large, painless, complex odontoma located in the right posterior mandible.

Keywords: Facial Asymmetry; Mandible; Odontogenic Tumors; Odontoma.

Fig. 4. A. Sagittal section of cone-beam computed tomography (CBCT) shows a dense homogeneous ground-glass radiopaque matrix with a horizontally aligned distinct molar-like tooth, adherent to the posteroinferior third of the mass. B. Axial section of CBCT shows the similar features of the sagittal section with a buccolingual expansion of the mandible. C. Coronal section of CBCT shows the similar features of the axial and sagittal sections with a buccolingual expansion and a tooth in the inferior portion of the lesion. Three-dimensional images of the lesion in the anteroposterior view (D) lateral view (E) submental view (F) show the expansion of cortical bones.
