Unusually large erupted complex odontoma: A rare case report.

Bagewadi SB, Kukreja R, Suma GN, Yadav B, Sharma H - Imaging Sci Dent (2015)

Bottom Line: 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.They are usually asymptomatic in nature.Occasionally, these tumors become large, causing bone expansion followed by facial asymmetry.

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.

No MeSH data available.

Panoramic radiograph shows the lesion as a well-defined radiopacity surrounded by a radiolucent halo with secondary inferior displacement and oblique horizontal impaction of the right mandibular second premolar.

Figure 3: Panoramic radiograph shows the lesion as a well-defined radiopacity surrounded by a radiolucent halo with secondary inferior displacement and oblique horizontal impaction of the right mandibular second premolar.

Mentions: The patient was subjected to radiological examination, which included panoramic radiography and cone-beam computed tomography (CBCT), to determine the extent of the lesion in three dimensions. The panoramic radiograph revealed a well-defined radiopaque mass with irregular borders situated in the right mandibular body. The mass extended anteroposteriorly from the distal surface of the first premolar to the anterior border of the mandibular ramus, and superoinferiorly from the occlusal plane to the lower third of the mandibular body. The radiopaque mass was surrounded by a thick radiolucent band, which in turn, was surrounded by cortication in the mesial, distal, and inferior aspects of the lesion. The degree of opacity was equivalent to that of the adjacent tooth structure with variable densities in some part of the lesion, which mimicked the pulpal tissue histologically. No evidence of the first and the second molars was noted. A horizontally aligned tooth-like structure was present in place of the third molar region, which was found to be submerged in the lesion. The solid mass was pushing the mandibular canal inferiorly towards the inferior border of the mandible, and the bowing of the lower border was evident inferior to the lesion. The second premolar was displaced apically and was mesially tilted with the resorption of the apical third portion of the root, whereas the first premolar was tilted distally with a slight resorption of the apex (Fig. 3).
