n a form characterized by the occurrence of an ameloblastoma within an odontoma. See also ameloblastoma; odontoma.

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.
