Odontogenic tumours and related jaw lesions
Chapter 11page 164
Neoplasms and other tumours affecting the jaws can be odontogenic, derived from odontogenic tissues, or nonodontogenic. It is not always obvious whether a swelling is odontogenic or not clinically.
Important causes of tumours (swellings) of the jaws:
1-Cysts, predominantly odontogenic cysts .
2-Odontogenic tumours 3-Giant cell lesions 4-Fibro-osseous lesions 5-Primary(non-odontogenic) neoplasms of bone 6-Metastatic neoplasms.Odontogenic tumours are the most common neoplasms of the jaws
There are many types, and the majority are rare. Odontogenic tumours may be derived from odontogenic epithelium (dental lamina, reduced enamel epithelium, rests of Serres, rests of Malassez) or products of odontogenic mesenchyme (dental follicle, dental papilla, pulp, periodontal ligament) or both in varying proportions. The dental follicle gives rise to the inner half of the lamina dura of the socket, so lesions of bone can be odontogenic too.
