Thus, the formation of AFO might be based on enamel matrix production, which is one of the most important features of the lesion.

Ameloblastic fibro-odontoma

The WHO classification of odontogenic sarcomas presented two entities: None, Conflict of Interest: A one-year postoperative follow-up revealed no evidence of recurrence, but only a mild gingival inflammation Figure 3. Ameloblastic fibro-dentinoma AFD is rare mixed odontogenic tumor composed of odontogenic epithelium, immature connective tissue and are characterized by the formation of dysplastic dentin. Extraosseous Dentinomq is extremely rare. After we had obtained the consent of the parents, we removed the mass using surgical scalpels; bleeding was stopped using electrocautery in the operating room.

The definitive differentiations between these clinically similar diseases depend on their microscopic findings. The hard fibrp constituent consists of foci of dentin and enamel with varying degrees of mineralization [ 2 ]. Clinically, it presents as a painless swelling of the affected area, usually the posterior portion of the maxilla or mandible.

It is important to note that in the revised WHO classification of odontogenic tumors, AFD and dentinoma are used synonymously. Conclusion Clinicians when dealing with radiopaque mass in posterior maxilla of children should keep the possibility of rare mixed odontogenic tumour in mind. Five months later, they went to the same clinic because the lesion became larger.


Peterson’s principles of oral and maxillofacial surgery. Ameloblastic fibroma and related lesions: Adequate clinical and radiological investigations, proper surgical excison, accurate histopathological diagnosis, and long term follow up will ensure the right treatment plan for the patient.

Suvy Manuel and Dr. The patient gave an unclear history of exfoliation of the posterior tooth. A trapezoidal flap was elevated and a thin bone covering the surface of the lesion was removed Fig.

Aggressive atypical ameloblastic fibrodentinoma: Report of a case

On gross examination the specimen consisted of a hard tissue mass with a soft tissue attachment. Well-circumscribed, unilocular radiolucency involving the impacted permanent canine Click here to view.

It is divided into two types on the stage of the development, immature and mature type. The reported extraosseous tumors do not appear in the oral mucosa other than gingiva.

On palpation lesion was firm in consistency, and gave the feeling of irregular surface. Clinical and radiographic appearances.

Isotype immunoglobulins Abcam were used to replace primary antibodies as negative control. Their clinical manifestations resemble much those of localized reactive gingival lesions [ 4 — 6 ].

However, in the present case detinoma, the connective tissue typically resembled the ectomesenchyme and thus the diagnosis of AFD was made.

The first is a neoplastic lesion, which if left in situ does not appear to mature further. There was grade II mobility with respect ameloblaetic 44 and 45, while the 46, 47 and 48 were absent. Others regard them as sequential stages beginning from AF at one extreme and complex odontoma at the other extreme with AFD and AFO in the intermediate stages.


Ameloblastic fibro-odontoma

The age range is 2. Tooth bud attached to the follicle around the lesion was removed.

Ameloblastic fibroma and related lesions: How to cite this article: Pre-operative intraoral view shows buccal and lingual expansion in the posterior mandible. Although the most common site for this tumor is the posterior dfntinoma, hereby we are reporting a case of AFD in the anterior maxillary region which is a very rare site for this group of tumors.

The section on low-power examination revealed neoplastic proliferation of odontogenic epithelial and mesenchymal tissue. In our patient, numerous small blood vessels were distributed near the odontogenic epithelium in the tissue sections.

Further, of similar interest is the relationship, fobro any, between the above three lesions and the fully calcified or mineralized odontogenic lesions, the odontomas. J Oral Maxillofac Surg. Clinical appearance 1 year after excisional biopsy for the gingival lesion.

Case Reports in Dentistry

OPG showed unerupted tooth bud of upper right second molar and was being prevented from eruption by the odontome. Majority of the articles state that the associated tooth bud has to be removed in order to avoid recurrence. AFO is normally found in young patients, with no significant gender predilection.

Usually, AFD radiographically presents as a well-defined radiolucency, with fibr dense opacity. Ameloblastic fibrodentinoma of mandible.
