ameloblastic fibro-odontoma

Wednesday 21 May 2008

Ameloblastic fibro-odontomas usually present in young adults in the posterior jaws.

Radiographically they may be unilocular or multilocular but are well circumscribed with a corticated border with a mixed radiolucency/radio-opacity appearance.

Microscopically there are island and cords of cuboidal epithelium in a myxoid background. Mineralization is seen with enamel, dentin and cementum formation. The mineralized material may be organized to resemble poorly formed teeth.

These lesions are treated conservatively with simple curettage and recurrences are rare.

Ameloblastic fibro-odontoma has features of ameloblastic fibroma but in addition they have enamel and dentin deposition.

Ameloblastic fibro-dentinoma is best regard as a variant of ameloblastic fibro-odontoma and has only dentin deposition.
