cementoma

 [se″men-to´mah]
a mass of cementum lying free at the apex of a tooth, probably a reaction to injury.

ce·men·to·ma

(sē-men-tō'mă),
Nonspecific term referring to any benign cementum-producing tumor; four types are recognized: periapical cemental dysplasia, central ossifying fibroma, cementoblastoma, and sclerotic cemental mass. When the type is not specified, cementoma usually refers to periapical cemental dysplasia.
[L. cementum, cement, + G. -ōma, tumor]

Pathological conditions mimicking FD can be classified as other fibro-osseous lesions like; cementoosseous dysplasia, ossifying fibroma, simple bone cysts, cementoma, Paget's disease, cherubism, hyperparathyroidism, chronic sclerosing osteomyelitis and osteogenic sarkoma.
The prevalence of AOT is less than odontoma, cementoma, myxoma, and ameloblastoma [13].
Cementoblastoma is a true neoplasm of cementum which is also designated as true cementoma. It constitutes less than 1% of the odontogenic tumor with distinctive features, occurring almost always in the posterior mandible region and usually affects young people less than 25 yrs.
Cementum-like bone production in solitary bone cysts (so-called "cementoma" of long bones): report of three cases--electron microscopic observations supporting a synovial origin to the simple bone cyst.
The others include periapical cementosseous dysplasis, cementifying fibroma and gigantiform familial cementoma. Benign cementoblastoma is a slow-growing benign tumor arising from cementoblasts.
Adenomatoid odontogenic tumours, accounting for approximately 3% of all odontogenic tumours, are less frequent than odontoma, cementoma, myxoma and ameloblastoma.
The World Health Organization first named this neoplasm "benign cementoblastoma" and also "true cementoma" in their 1971 classification.
(1) In addition to fibrous dysplasia, the differential diagnosis on imaging should include osteoma, cementoma, and osteosarcoma.
The 2005 WHO classification divides these bone-related lesions into periapical, focal, florid cemento-osseous dysplasias and familial gigantiform cementomas. (3) These appear as single or multifocal, well-defined, cement-like sclerotic lesions in a periapical location with surrounding lucent halo (Figure 10).
Benign processes include nasal polyps, mucoceles, meningoencephaloceles, chrondromas, osteomas, ossifying fibromas, and cementomas. Vascular anomalies, including an internal carotid artery aneurysm, should also be considered, especially in the sphenoid sinus.
