What is a odontoma?

1. Introduction. Odontoma is a benign odontogenic tumor. The term odontoma was first coined by Broca (1866); he defined it as a tumor formed by an overgrowth of complete dental tissues [1]. Based on gross, radiographic, and microscopic features, odontomas are classified into complex odontoma and compound odontoma.

Do odontomas 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.

What causes an odontoma?

Overall aetiology is unknown. However, odontomas have been related to local trauma, inflammatory and/or infectious processes, hereditary anomalies such as Gardener’s syndrome and Hermanns syndrome, odontoblastic hyperactivity, mature odontoblasts and dental lamina remnants (Cell Rests of Serres).

Are odontomas painful?

Usually odontomas are asymptomatic. Clinical indicators of odontoma may include retention of deciduous teeth, noneruption of permanent teeth, pain, expansion of cortical bone, and tooth displacement. Pain and swelling are the most common symptoms when odontomas erupt, followed by malocclusion.

Do Odontomas grow?

Odontomas are generally small; however, they may occasionally grow large, resulting in bone expansion.

Is Odontoma cancerous?

Odontomas are not cancer. They are considered benign tumors, though in humans they are often surgically removed.

Are Odontomas asymptomatic?

Odontoma is considered to be the most common odontogenic tumor of the oral cavity. Most odontomas are asymptomatic and are discovered during routine radiographic investigations and can cause disturbances in the eruption of the teeth, most commonly delayed eruption or deflection.

How is odontoma diagnosed?

Usually, odontomas can be confidently subclassified based on the radiographic appearance alone (1–7). Although they are commonly asymptomatic, clinical indicators of odontoma may include retention of deciduous teeth, noneruption of permanent teeth, pain, expansion of the cortical bone and tooth displacement (9–14).

How common are odontogenic tumors?

Individually, of all odontogenic tumors, 75.9% were odontomas. The prevalence of the remaining tumors appears to be a rare occurrence. The second most common was ameloblastoma (11.7%), followed by odontogenic myxoma (2.2%). Odontomas are considered hamartomas or developmental anomalies.

How is an odontoma removed?

Odontoma requires surgical removal via local excision. The clinical diagnosis may be verified by histological examination. Unlike other tumors, odontoma shows no inclination to recurrence.

What is the medical dictionary definition of odontoma?

Also found in: Dictionary, Encyclopedia, Wikipedia. any odontogenic tumor, especially a composite odontoma. ameloblastic odontoma a rare, slow-growing, mixed tumor of odontogenic origin that combines the characteristics of composite odontoma and ameloblastoma.

What’s the difference between a compound odontoma and an odontogenic tumor?

1. A tumor of odontogenic origin. 2. A hamartomatous odontogenic tumor composed of enamel, dentin, cementum, and pulp tissue that may or may not be arranged in the form of a tooth. A tumor of odontogenic origin–ie, which arises from the dental epithelium. See Complex odontoma, Compound odontoma. 1. A tumor of odontogenic origin. 2.

What kind of tumor is an ameloblastic odontoma?

any odontogenic tumor, especially a composite odontoma. ameloblastic odontoma a rare, slow-growing, mixed tumor of odontogenic origin that combines the characteristics of composite odontoma and ameloblastoma. composite odontoma one consisting of both enamel and dentin in an abnormal pattern.

What are the different types of odontoma teeth?

There are two main types: compound and complex. A compound odontoma still has the three separate dental tissues (enamel, dentin and cementum), but may present a lobulated appearance where there is no definitive demarcation of separate tissues between the individual “toothlets” (or denticles). It usually appears in the anterior maxilla.
