Cone-beam tomography panoramic reconstruction showing a well-circumscribed calcified odontom in intimate contact with the alveolar inferior nerve. I ntroduction Ameloblastic fibroodontomas AFOs are slow-growing, benign tumors developing from the odontogenic epithelium and ectomesenchyme. An AFO is an immature variant of complex odontoma, as the clinical and radiographic findings are identical.

Amsloblastic free access to newly published articles Create a personal account or sign in to: This lesion usually occurs in people less than 20 years old, and age is thus an important characteristic in the differential diagnosis. Compound odontoma and unerupted No evidence of malignancy is found.

She had radiographic examinations, including panoramic, helical, and cone-beam computed tomography. Odonotma of a case-dependent treatment plan may provide an optimum outcome. Ameloblastic fibro-odontoma AFO is a benign, slow growing, expansile epithelial odontogenic tumor with odontogenic mesenchyme.

Ameloblsatic photograph showing diffuse swelling over the left side of the lower face. Histopathologically, an AFO and a complex odontoma are indistinguishable.

Helical and cone-beam computed tomography showed an expansile well-circumscribed lesion containing at the interior a calcified mass compatible with odontogenic tissue Figures 2 and 3. The table compares Gorlin’s survey composed of his own case plus those cases reported in the earlier literature which he thought belonged in this diagnostic category with Hooker’s survey 26 cases.


Slootweg reviewed ameloblastif cases with this condition, for which the mean age was 8.

With the help of a chisel and mallet, the outer cortical bone overlying the tumor was then removed. A 15 year old boy is found to have multiple odontomas of the left mandibular body.

It may inhibit tooth eruption or displace involved teeth although teeth in the affected area are vital [ 1 — 3 ]. We report a case of an year-old female patient with missing mandibular molars on the left side associated with a giant complex odontoma. Am J Dis Child. This lesion is usually found in the molar area [ 612 ], and the distribution is roughly equal between the maxilla and mandible [ 6 aneloblastic, 12 ]. After achieving proper hemostasis, closure was done in layers. The mixed odontogenic tumours.

After reflection of the periosteal layer, the expanded buccal cortex was seen. Click here for patient related inquiries.

Radio opaque lesion surrounded by radiolucent zone. Light microscopic examination of sections stained with hematoxylin and eosin revealed strands and islands of odontogenic epithelium showing peripheral palisading and loosely arranged central cells, identical to stellate reticulum, embedded in a myxoid cell-rich stroma resembling the dental papilla Figure 4.

The patient underwent enucleation of the lesion and careful curettage of the surgical cavity under general anesthesia. Our website uses cookies to enhance your experience. Orphanet J Rare Dis ;1: This is in contrast to the ameloblastoma. We present a case of an year-old female with giant complex odontoma present in the body of the mandible leading to an impacted mandibular third molar. The clinical examination did not display any sign of pain or swelling in the left mandible.
