They can occur at any age, although typically are diagnosed in the 2nd decade of life. They are divided histologically into: complex odontoma : irregular calcified lesions with no distinct tooth components compound odontoma : identifiable tooth components Associations Approximately half will be associated with an unerupted tooth, the rest being diagnosed both before or after tooth eruption. Radiographic features Initially, the tumor is lucent, but with time, it develops small calcifications which eventually coalesce to form a radiodense lesion with a lucent rim. Epithelial components may occasionally give rise to a dentigerous cyst.

Abstract Background: Odontogenic tumors such as ameloblastic fibro-odontoma AFO are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling. Materials and Methods: A case of an AFO in a 7-year-old girl is described, and cases from the literature and this report are analyzed. Results: The total of cases revealed the average age at presentation of AFO to be 6.
There was a slight male predilection and AFO lesions most often occurred in the posterior mandible. AFO was almost always associated with an unerupted tooth or teeth. Conclusions: While the recurrence rate of AFO was found to be 5.
Large ameloblastic fibro-odontoma in a 7-year-old girl with analysis of cases. It is relatively rare. Studies indicate that AFO is seen ranging from 0. Only a few studies exist regarding the characteristics of AFOs as most case reports take the form of single patient publications.
Case report An otherwise healthy 7-year-old girl was referred by her dentist because of swelling of the left side of the mandible. An asymmetric facial swelling was obvious on extraoral examination [Figure 1].
There was no history of trauma or local infection. Intraoral examination revealed normal mucosa overlying the lesion and the absence of the left mandibular first and second molar teeth [Figure 2]. A distinctive hard bulge was palpable in the vestibule of the left mandible molar region. The mouth opening was normal and there was no pain or other symptoms apart from the swelling. Panoramic radiography [Figure 3] and cone-beam computed tomography scan [Figure 4] and [Figure 5] both revealed a large well-defined radiolucent area that contained several radiopaque structures of varying sizes and shapes.
The lesion extended from the first molar to the coronoid process and the condylar neck. The borders of the lesion were well circumscribed and the lesion had displaced the developing second molar tooth bud down to the inferior border of the mandible.

Ameloblastic Fibro-Odontoma: A Diagnostic Challenge
Figure 3 Cone-beam tomography panoramic reconstruction showing a well-circumscribed calcified mass in intimate contact with the alveolar inferior nerve. Considering the clinical and radiographic examinations, our presumptive diagnosis was complex odontoma. The patient underwent enucleation of the lesion and careful curettage of the surgical cavity under general anesthesia. 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. Dentin and enamel were also present Figure 5. The final diagnosis was AFO. The patient is being followed up postoperatively and there is no sign of recurrence.
Picture : Odontoma Symptoms of Odontoma There are many symptoms of Odontoma but they are often overlooked or misdiagnosed. One that is serious is difficulty with swallowing. If a tooth is delayed when it ought to be erupting, that is another sign that something is not right. If you have a lump in your gum that could be a symptom of odontoma. Some may be confused initially with an impacted wisdom tooth.
