odontoma, ameloblastic
n a form characterized by the occurrence of an ameloblastoma within an odontoma. See also ameloblastoma; odontoma.
odontoma, complex,
n an odontogenic tumor characterized by the formation of calcified enamel and dentin in an abnormal arrangement because of lack of morphodifferentiation.
odontoma, compound,
n a tumor of enamel and dentin arranged in the form of anomalous miniature teeth. Several small abnormal teeth surrounded by a fibrous sac.

odontoma

ameloblastic odontoma
contains true neoplastic ameloblastic tissue. See ameloblastic odontoma.
complex odontoma
all the dental tissues are represented but not in an organized form.
composite odontoma
one consisting of both enamel and dentine in an abnormal pattern.
compound odontoma
all the dental tissues are present and organized into denticles, tooth-like structures.
radicular odontoma
one associated with a tooth root, or formed when the root was developing.
temporal odontoma
most commonly in the mastoid process of the petrous temporal bone manifested as a discharging sinus at the base of the ear. Is a dentigerous cyst.
