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.
[a Case of Cementoma
Localized on a Temporary Molar].
The prevalence of AOT is less than odontoma, cementoma
, myxoma, and ameloblastoma .
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.
