Multiple Extensive Complex Odontomas of the Jaws

Frequently associated with an unerupted tooth Usually detected on routine radiographs Most commonly located between roots of erupted teeth or impeding the eruption of tooth Well marginated from surrounding bone May have a thin radiolucent region surrounding opaque mass Radiopaque matrix same density as components of adjacent teeth Early stage odontoma may have little calcified matrix, expanding the radiographic differential diagnosis Can occur as a component of combined odontogenic tumor, most commonly Calcifying cystic odontogenic tumor CCOT Multiple odontomas may occur as a component of: The aetiology of complex odontomas is unknown.

Int J Oral Surg ;9: In the initial stage, there is lack of calcification of the dental tissues making it to appear radiolucent. Can occur in any tooth bearing area Compound odontoma usually occurs in anterior maxilla Complex odontoma usually occurs in posterior mandible. Considering the above clinical findings, a provisional diagnosis of a residual cyst in the mandibular left molar region was made, with a differential diagnosis of ameloblastoma and periapical cemental dysplasia.


J Oral Maxillofac Surg ; Case report and review of the literature. Laterally, the lesion extended into the buccal vestibule causing vestibular obliteration.
