What is odontogenic cyst?
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 percentage of dental cysts are cancerous?
The incidence of carcinomas, either squamous or mucoepidermoid, originating from odontogenic cysts represents less than 1% (5,19). According to Muller and Waldron (34), 70% of primary intraosseous carcinomas develop from pre-existing cysts and these account for 1 to 2% of overall oral cancers (15,42,43).
Are dental cysts benign?
