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. Recent epidemologic studies has revealed that prevalence of Odontogenic Lesions or Tumours in Switzerland was 2.67%.
Odontogenic infections arise either from pulp death, secondary most commonly from dental decay, alternatively they commence in the pericoronal tissues. In both instances they are of oral microbial origin. Dependent on the type, quantity and virulence of the micro-organisms they may spread into the maxilla or mandible and then into the surrounding face, jaws or neck. Although there are many other causes of head and neck infection, odontogenic infections are the most common type.
