What is an Ameloblastic odontoma?

What is Ameloblastic fibroma?

Ameloblastic fibroma (AF) is an extremely rare true mixed benign tumor that can occur either in the mandible or maxilla.[1] It is frequently found in the posterior region of the mandible, often associated with an unerupted tooth.[2] It usually occurs in the first two decades of life with a slight female predilection,

What is a odontoma?

Odontomas are the most common odontogenic tumours. They are considered to be hamartomas rather than neoplasms, and are composed of the tissues native to teeth: enamel, dentin, cementum and pulp tissue. They develop from epithelial and mesenchymal components of the dental apparatus, producing enamel and dentin.

What causes complex odontoma?

The origin of complex odontoma is unknown; some suggest trauma or infection to be the cause. In a study conducted by Lopez-Areal et al., they found that a child developed multiple odontomas after experiencing trauma with intrusion of incisor teeth at the age of 10 months [7].

Is Odontoma cancerous?

Ameloblastoma is the most common with 39.6 percent of odontogenic tumors. Odontomas are not cancer. They are considered benign tumors, though in humans they are often surgically removed.

What causes Ameloblastic fibroma?

There is a slight male predilection, developing most commonly within the first two decades of life. They are often identified when tooth development is complete with the posterior mandible being the most common site.

Does an odontoma need to be removed?

While an odontoma is a tumor, it’s a benign one and not uncommon. That alone is great news! However, odontomas usually require surgical removal. They’re made up of dental tissue that resembles abnormal teeth or calcified mass that invade the jaw around your teeth and could affect how your teeth develop.

How is odontoma treated?

Odontoma is the most common odontogenic benign tumor, and the treatment of choice is generally surgical removal. After excision, bone grafts may be necessary depending on the need for further treatment, or the size and location of the odontoma.

How rare is an odontoma?

Odontomas constitute about 22% of all odontogenic tumors of the jaws. Approximately, 10% of all odontogenic tumors of the jaws are compound odontomas. The incidence of compound odontome ranges between 9 and 37% and the complex odontome is between 5 and 30%.

What is the most common odontogenic tumor?

Odontoma. This benign tumor is the most common odontogenic tumor. Odontomas often have no symptoms, but may interfere with tooth development or eruption. Odontomas are made up of dental tissue that grows around a tooth in the jaw.

Does Odontoma cause pain?

Odontomas rarely erupt into the mouth and tend to be associated with impacted teeth. Despite their benign nature, however, their eruption into the oral cavity can give rise to pain, inflammation, and infection and different clinical appearance.

What is the difference between Odontoma and supernumerary tooth?

Odontomas are classified under supernumerary according to the Howard classification. [8] Compound odontomas are more common and affect the anterior maxilla, and odontomas are associated mostly with permanent and rarely with deciduous teeth. [9] The etiology is not completely understood.

How fast do jaw tumors grow?

The tumors usually grow slowly over many months or even years. For a while, the only symptom may be swelling in the back of your jaw. You also might have tooth or jaw pain.

Are Odontomas genetic?

Odontoma dysphagia syndrome (Bader syndrome) is a rare syndrome (<10 cases reported to date) first described in 1967. The cause is not known but it is suspected to be genetic in origin.

What causes compound composite Odontoma?

It has been associated with various pathological conditions, like local trauma, inflammatory and/or infectious processes, mature ameloblasts, cell rests of serres (dental lamina remnants) or hereditary anomalies (Gardner’s syndrome and Hermann’s syndrome), odontoblastic hyperactivity, and alterations in the genetic

What is calcifying odontogenic tumor?

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region.

What are calcifying epithelial odontogenic tumor?

A calcifying epithelial odontogenic tumor (CEOT) is a locally invasive epithelial neoplasm characterized by the development of intraepithelial structures, probably of an amyloid-like nature, which may become calcified and liberated as the cells break down.

What is calcifying odontogenic cyst?

The calcifying odontogenic cyst (COC) is a benign odontogenic cyst that occurs in the gnathic bones. This cyst is part of a spectrum of lesions characterized by odontogenic epithelium containing “ghost cells,” which may undergo calcification.

What is ossifying fibroma?

Ossifying fibroma is a rare benign fibro-osseous neoplasm of the jaw characterized by substitution of normal bone by fibrous tissues and newly formed calcified products such as bone, cementum or both. It is a well-demarcated lesion that differentiates it from fibrous dysplasia.

What is odontogenic myxoma?

Odontogenic myxoma is a rare intraosseous neoplasm, which is benign but locally aggressive. It rarely appears in any bone other than the jaws. It is considered to be derived from the mesenchymal portion of the tooth germ.

Is hamartoma a neoplasm?

A hamartoma is a mostly benign, local malformation of cells that resembles a neoplasm of local tissue but is usually due to an overgrowth of multiple aberrant cells, with a basis in a systemic genetic condition, rather than a growth descended from a single mutated cell (monoclonality), as would typically define a

How is fibroma treated?

Treatment options include steroid injections, orthotic devices, and physical therapy. If you continue to experience pain after trying these approaches, if the mass increases in size, or if your pain increases, surgical treatment is an option. Neither dermatofibroma nor plantar fibroma is serious or life threatening.

What is odontogenic cyst?

Odontogenic cysts are epithelial-lined pathologic cavities and surrounded by fibrous connective tissue that originate from odontogenic tissues that occur in tooth-bearing regions of maxilla and mandible. Cystic conditions of the jaw cause bony destruction and may cause resorption or displacement of adjacent teeth.

What is compound composite Odontoma?

Composite odontoma is a rare defect in humans in which a benign tumor forms in the mouth, generally as a result of the abnormal growth of a single tooth, causing additional teeth to form within the tumor. Most cases have been found in the upper jaw of patients.

What is an eruption cyst?

Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they hurt, bleed or are infected they may require surgical treatment to expose the tooth and drain the contents.

What is Amelogenesis imperfecta?

Amelogenesis imperfecta (AI) refers to a group of rare, inherited disorders characterized by abnormal enamel formation. The term is typically restricted to those disorders of enamel development not associated with other abnormalities of the body.
