Ameloblastic fibro-odontoma
Updates to Article Attributes
Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumour that usually arises in the maxilla and mandible. According to the 2005 WHO classification of odontogenic tumours, it is defined as a benign tumour which resembles ameloblastic fibroma but contains enamel and dentin.
Epidemiology
Ameloblastic fibro-odontoma is most frequently diagnosed in 1st and 2nd decade of life with peak age between 8 and 12 years and does not show any gender or anatomic site predilection.
The prevalence of ameloblastic fibro-odontoma is in the range of 0–3.4% within odontogenic tumours among different regions.
Clinical presentation
Clinical presentation is with painless swelling usually along the posterior maxilla or mandible and delayed tooth eruption in affected region.
Pathology
Ameloblastic fibro-odontoma is classified into benign tumours with odontogenic epithelium with odontogenic ectomesenchyme and with or without hard tissue formation according to 2005 WHO classification of odontogenic tumours.
The tumour contains soft and hard tissues components which resemble dental papilla and foci of enamel and dentin respectively.
Radiographic features
Plain radiograph
Ameloblastic fibro-odontoma is usually well-defined unilocular radiolucent mass having a variable amount of radiopaque material within it and is associated with the crown of an unerupted tooth/teeth.
Treatment and prognosis
Conservative surgical enucleation is the treatment of choice in well defined non-aggressive lesions. However, in destructive lesions, surgical resection with partial maxillectomy or partial mandibulectomy may be required. Recurrence is uncommon but can occur as a result of inadequate surgical removal.
