Ameloblastic odontoma | definition of ameloblastic odontoma by Medical dictionary

After reflection of the periosteal layer, the expanded buccal cortex was seen. Get free access to newly published articles. The tumor mass is surrounded by a fibrous capsule and is ameloblastix predominantly of a fibroblastic connective tissue matrix containing strands of odontogenic epithelium and immature tooth structures, including enamel and dentin.

An impacted third molar was present below the mass just above the inferior border [ Figure 3 ].

ameloblastic odontoma

Compound odontoma Complex odontoma Ameloblastic fibro-odontoma Peripheral odontoma. Differential diagnoses include lesions with mixed radiographic features, such as immature complex odontoma, calcifying epithelial odontogenic tumor, adenomatoid odontogenic tumor, and ameloblastoma. This paper describes an extensive AFO in an year-old girl. It has been reported in the literature under a variety of names including odontoblastoma, 1 adamantoodontoma, 2 calcified mixed odontogenic tumor, 3 and soft and calcified odontoma.

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. With the help of a chisel and mallet, the outer cortical bone overlying the tumor was then removed. Support Center Support Center. They are usually found to be asymptomatic and are most often discovered on routine radiography. Treatment included surgical excision of the tumor followed by reconstruction with odonotma crest graft.


Abstract An ameloblastic fibroodontoma AFO is a rare odontogenic tumor of mixed dental tissue origin. Sign in to make a comment Sign in to your personal account. Surgical site showing denticles. Many authors reported that AFO is not aggressive and can be treated adequately through a surgical curettage to the lesion without removal of the adjacent teeth [ 14578 ]. Home About Us Advertise Amazon. Ameloblastic fibro-odontoma AFO is a benign, slow growing, expansile epithelial odontogenic tumor with odontogenic mesenchyme.

As it is a noninvasive tumor, recurrence is very rare. Ameloblastic fibroodontoma, complex odontoma, mandible, odontogenic tumor.

On intraoral examination, a small hard tissue projecting over the posterior alveolus was present with normal surrounding mucosa.

The final diagnosis was AFO. This lesion occupied a zone from the lower left second molar area to the left ramus. It arises from an exuberant proliferation of the dental ameloblxstic or its remnants. The diagnosis was ameloblastic fibro-odontoma, which is a rare mixed odontogenic tumor, derived from epithelial and ectomesenchymal elements that form the dental tissues.

Pathology Outlines – Odontoma

The patient underwent enucleation of the lesion and careful curettage of the surgical cavity under general anesthesia. Page views in View at Google Scholar Ameloblasfic. In some studies, the term AFO represents a histological combination of ameloblastic fibroma and complex odontoma [ 1216 ]. If there is a recurrence accompanied by a change of the histological pattern toward a more unorganized fibrous stroma with displacement of the epithelial component, then more extensive treatment procedures appear to be indicated [ 19 odntoma.

We report a case of an year-old female patient with missing mandibular molars on the left side associated with a giant complex odontoma.

Mixed epithelial and mesenchymal tumor-like malformation hamartoma composed of dental hard and soft tissues. The majority now agrees that AFO exists as a distinct entity, but it can be histologically indistinguishable from immature complex odontoma.

Accessed December 31st, Many asymptomatic; discovered upon exploring potential causes of Asymmetric tooth eruption Malposition of erupted teeth Occasional devitalization of adjacent teeth Can become symptomatic due to local infection odontoam, infected adjacent tooth, exposure of odontoma to oral environment, etc and can present with swelling and pain Size: Orthopantomogram revealsa large, well-defined radiopaque lesion with focal radiolucent areas occupying aneloblastic whole left body of the mandible.

More disorganized or haphazard arrangement of pulpal tissues, enamel or dentin. 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 amelloblastic resembling the dental papilla Figure 4.

The defect was measured to be approximately 6 cm in length. An impacted tooth is also visible.

Postoperative recovery was absolutely uneventful. Contributed by Kelly Magliocca, D. The lesions are usually diagnosed during the first and second decades of life [ 4 — 6 ].

The diagnosis of complex odontoma was made. Unknown; trauma, local infection, inheritance have been proposed. An year-old female presented to our unit with the complaint of a painless swelling on the left side of the lower jaw for the last 3 years that seemed to show a progressive increase in amelkblastic.
