cementoblastoma

 [se-men″to-blas-to´mah]
an odontogenic fibroma whose cells are developing into cementoblasts and in which there is only a small proportion of calcified tissue.

ce·ment·o·blas·to·ma

(sē-men'tō-blas-tō'mă),
A benign odontogenic tumor of functional cementoblasts; it appears as a mixed radiolucent-radiopaque lesion attached to a tooth root and may cause expansion of the bone cortex or be associated with pain.

Cementoblastoma, osteoid osteoma, cemento-osseous lesions, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and ameloblastic fibro-odontoma were also considered in the differential diagnoses.
On the basis of the clinical and radiographic features, the differential diagnosis of this lesion included odontoma, cementoblastoma, and osteoblastoma.
Based on radiographs only, the oral radiologists were able to identify several radiographic features that were deemed characteristic of COD and accordingly were able to correctly differentiate the majority of COD cases from dense bone island, cementoblastoma, cemento-ossifying fibroma, fibrous dysplasia, complex odontoma and sclerosing osteitis.
Benign cementoblastoma (BC) is a rare and benign odontogenic mesenchymal tumor, often characterized by the formation of cementum-like tissue produced by neoplastic cementoblasts attached to or around the roots of a tooth.
Cementoblastoma is a benign odontogenic mesenchymal tumor that is associated with and attached to the roots of teeth.
The cementoblastoma was first described by Dewey in 1927 as an odontogenic tumor of mesenchymal origin [1].
The closest differential is cementoblastoma (Figure 11), which occurs in children and fuses to the tooth root, unlike cementosseous dysplasia.
like atherosclerosis, acromegaly, deforming arthritis, hypertrophic arthritis, thyroid diseases, and Paget's disease have been described to be associated with the occurrence of hypercementosis.6 In addition, cementoblastoma must also be taken into consideration as a differential diagnosis.7 The characteristic radiographic appearance of hypercementosis is thickening of the cementum layer along with blunting or rounding of the root tip with various expressions of the trait from mild to severe.8 The biological width between the root surface, the alveolar bone and the periodontal ligament is found intact on the radiographs.
Among the radiopaque lesions two cases were odontomas (67%), and one case was cementoblastoma (33%).
Benign cementoblastoma is one of 4 World Health Organization recognized cemental neoplasms.
Clinical differential diagnosis included an odontogenic keratocyst, dentigerous cyst, ameloblastoma, odontoma, calcifying epithelial odontogenic cyst, benign cementoblastoma, benign osteoblastoma, and central ossifying fibroma.
