(4) The differential diagnoses of POT includes ameloblastic fibroma
and odontogenic fibroma/myxoma.
Odontogenic benign tumors, mixed Ameloblastic fibroma
Differential diagnosis like ameloblastoma, ameloblastic fibroma
, odontogenic fibroma, central hemangioma, or odontogenic keratocyst along with OM could be listed as initial diagnostic hypothesis based on the clinical and radiological findings.
Mostly, nonneoplastic causes of jaw swelling in a young patient are an apical cyst, dentigerous cyst, calcifying odontogenic cyst, odontogenic keratocyst, and central giant cell granuloma [3, 10-12], whereas common neoplastic causes are an adenomatoid odontogenic tumor, unicystic ameloblastoma, calcifying epithelial odontogenic tumor (CEOT), ameloblastic fibroma
, and ameloblastic fibroodontoma [3, 12, 13].
Previously, concept stated this lesion to be continuum of differentiation from ameloblastic fibroma
to complex odontoma.
Presence of dentin and enamel is the differentiating point between ameloblastic fibro odontoma and ameloblastic fibroma
and ameloblastoma (Walsh et al., 1987).
Our Differential Diagnosis Includes: Dentigerous cyst, Keratocyst, Ameloblastoma, Ameloblastic fibroma
, Odontogenic fibroma, Adenomatoid odontogenic tumor, Calcifying epithelial odontogenic tumor, Ameloblastic fibro-odontoma, and Calcifying odontogenic cyst.
