• odontoameloblastoma
  21 May 2008

  Odontoameloblastomas are extremely rare oral tumors. For the cases that have been described, they happen to occur in the mandible of young patients.
  In contrast to AF, they are destructive lesions on radiographs and have calcifying components.

  Biologically, they tend to behave like ameloblastoma and characterized by multiple recurrence and local aggression.
