What are non odontogenic tumors?
Nonodontogenic tumors of the jaws are common in the pediatric population; these tumors include giant cell lesions, fibro-osseous lesions, and desmoplastic fibroma.
What is non odontogenic lesion?
A lesion associated with an impacted tooth frequently indicates an odontogenic origin. Nonodontogenic lesions, however, develop from osseous origin and are not tooth-related. These lesions usually, but not always, consist of a group of pathologies which may be seen anywhere in the axial skleton.
Is osteoblastoma benign?
Osteoblastoma is a rare benign bone tumor that accounts for about 1 percent of all primary bone tumors in the United States. It affects twice as many boys as girls. Similar to most primary benign bone tumors, osteoblastoma tends to form in the extremities, however it also often forms in the spine.
What is an osteoma in the jaw?
Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type.
What are non-odontogenic infections?
This volume of Periodontology 2000 distinguishes between odontogenic infections, such as periodontitis, dental caries, endodontic infections, pericoronitis and dental abscesses, and non-odontogenic infections where teeth are not involved.
What is the most common non-odontogenic tumor?
Central giant cell granuloma is the most common non-odontogenic tumor that affects the jaws, accounting for 7% of benign jaw tumors. They are most commonly found in the anterior portion of the mandible but can affect the maxilla. They are benign but can be locally destructive.
Which is the most common non-odontogenic cyst?
The most common OCs (57.2%) were dentigerous and radicular, whereas the most common nonodontogenic cyst (42.8%) was nasopalatine duct cyst. Other soft tissue cysts reported were epidermoid, branchial, thyroglossal, dermoid, and cystic hygroma.
Is osteoclastoma malignant?
The giant cell tumor of bone (GCTB), also known as an osteoclastoma or a myeloid sarcoma, is a benign local aggressive osteolytic neoplasm that primarily affects skeletally mature young adults.
Which syndrome is associated with multiple osteomas?
Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth.
