Human Tooth Diagram. Cementoma is an odontogenic tumor of cementum.It is usually observed as a benign spherical mass of hard tissue fused to the root of a tooth. [1] It is found most commonly in the mandible in the region of the lower molar teeth, occurring between the ages of 8 and 30 in both sexes with equal frequency . [1]
A cyst may become acutely infected, and discharge into the oral cavity via a sinus. Adjacent teeth may be loosened, tilted or even moved bodily. [6] Rarely, roots of teeth are resorbed, depending upon the type of cyst. The inferior alveolar nerve runs through the mandible and supplies sensation to the lower lip and chin.
As with normal tooth development, odontomas stop growing once mature which makes them benign. [6] The average age of people found with an odontoma is 14. [7] The condition is frequently associated with one or more unerupted teeth and is often detected through failure of teeth to erupt at the expected time. Though most cases are found impacted ...
On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction. It should be differentially diagnosed from a dentigerous cyst and the main difference is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction.
Patients afflicted with an odontogenic myxoma generally notice a painless, slowly enlarging expansion of the jaw with possible tooth loosening or displacement. [3] As the tumor expands, it frequently infiltrates adjacent structures. Maxillary lesions frequently enter the sinuses while mandibular tumors often extend into the ramus. [1]
Ameloblastoma is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. [1] It was recognized in 1827 by Cusack. [2]
Odontogenic keratocysts are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as residual cysts or a dentigerous cyst if they occur over an unerupted tooth. [8] Relative incidence of odontogenic cysts. [9]
Cementoblastoma, or benign cementoblastoma, is a relatively rare benign neoplasm of the cementum of the teeth. It is derived from ectomesenchyme of odontogenic origin, with the formation of cementum-like tissue around the associated tooth root. [2] Cementoblastomas represent less than 0.69–8% of all odontogenic tumors. [2]
