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
