[3] He described a lesion as a hard rounded mass associated with root resorption, periosteum coverage, rows of bone cells, and pulp chamber involvement.

Clinical Cementoblastoma usually occurs in people between the ages of 20 to 30, equally affecting males and females.

Differential diagnosis include severe hypercementosis, chronic focal sclerosing osteomyelitis, and osteoma.

Histologic Cementoblastoma can be characterized by a fibrous stroma containing a dense collection of acellular material that is cementum-like with basophilic reversal lines[6].

Rearrangement of the FOS gene and overexpression of c-FOS have been identified in cementoblastoma, similar to osteoblastoma suggesting a link in the disease process of these two tumors.
