What are non-odontogenic cysts?
Non-odontogenic cysts are usually discovered during a routine examination. These lesions arise from the non-odontogenic (non-tooth forming) tissue. By definition, the cysts are lined by epithelium. Cysts within the oral cavity vary in their clinical appearance, incidence, histology, behavior, and management.
Which cyst is not an odontogenic cyst?
For example, mucous cyst of the oral mucosa and nasolabial duct cyst are not of odontogenic origin.
How do you classify a cyst?
A cyst is a uni- or multilocular, epithelium-lined cavity of various etiologies that contains liquid or gaseous materials. Non-epithelium-lined cavities are classified as “pseudocysts”. In clinical practice, both pseudocysts and cysts are generally referred to as “cysts”.
What is the difference between odontogenic and Nonodontogenic cysts?
Odontogenic cysts arise from remnants of the odontogenic epithelium entrapped in bone or gingival tissue, while non-odontogenic cysts develop from epithelium of non-odontogenic origin.
What does non odontogenic mean?
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.
What causes odontogenic cysts?
Causes of Dentigerous Cysts Generally, odontogenic tumors and cysts emanate from cells and tissues involved in normal tooth developments. Most are closely linked to genetic syndromes. If you have nevoid basal cell carcinoma syndrome, your body lacks a gene responsible for the suppression of tumors.
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.
What are odontogenic cysts?
Odontogenic cysts are epithelial-lined pathologic cavities and surrounded by fibrous connective tissue that originate from odontogenic tissues that occur in tooth-bearing regions of maxilla and mandible. Cystic conditions of the jaw cause bony destruction and may cause resorption or displacement of adjacent teeth.
What is a Bosniak type 3 cyst?
Bosniak category III cystic masses are of indeterminate origin and present suggestive signs of malignancy. [1] The typical appearance includes uniform wall thickening, thickened and irregular calcifications, and thickened and irregular or multiple septa (>1 mm) without an intracystic nodular lesion.
Which is the most common non-odontogenic cyst?
What are non-odontogenic Tumours?
Primary intraosseous tumors of non-odontogenic origin arising in children and adolescents include osteoma and osteoblastoma, Langerhans cell histiocytosis, desmoplastic fibroma, inflammatory myofibroblastic tumor, juvenile ossifying fibroma, Ewing sarcoma and osteosarcoma, and primary intraosseous lymphoma.
What are non-odontogenic tumors?
Nonodontogenic tumors are those orofacial tumors which do not arise from the dental epithelial and mesenchymal.
