An odontogenic tumor is a neoplasm of the cells or tissues that initiate odontogenic processes. Examples include: Adenomatoid odontogenic tumor, Ameloblastoma, a type of odontogenic tumor involving ameloblasts, Calcifying epithelial odontogenic tumor, Calcifying epithelial odontogenic tumor, Keratinising cystic odontogenic tumor, Odontogenic myxoma, Odontoma. The epidemiological profile of odontogenic and non-odontogenic intrabony lessions located in the maxilla and mandible in the Queensland population of Australia (4.56 million) was investigated over a 12 month period.
For odontogenic cysts there was an overall male:female ratio of 1.2:1, a maxilla:mandible ratio of 1:1.3, with a mean age of 43.4 years. Radicular cyst was the most frequent (247/540, 45.7%, mean age of 50.5 years), followed by “odontogenic cyst not otherwise specified” (151/540, 28.0%, mean age of 36.5 years) and the dentigerous cyst (121/540, 22.4%, mean age of 36.5 years). Odontogenic tumours had an overall male:female ratio of 1.5:1, a maxilla:mandible ratio of 1:2.3, with a mean age of 43.5 years. The overall incidence of odontogenic tumours was 20.4/million. Researches focusing on Evaluation of Amelotin Expression in Benign Odontogenic Tumors, Evaluation of Neoplastic Nature of Keratocystic Odontogenic Tumor Versus Ameloblastoma, Immunohistochemical detection of laminin-1 and Ki-67 in radicular cysts and keratocystic odontogenic tumors.
