Abstract
Lesions specific for the jaws and not occurring in any other bones mostly are related to the teeth or to odontogenic tissues. Moreover, the jaws may harbor nonodontogenic bone lesions not seen in any other part of the skeleton. This paper pays attention to the diseases that are specific for the jaws, odontogenic as well as nonodontogenic. Both neoplastic and nonneoplastic entities will be discussed.
Highlights
Jaw bone differs from other bones in several aspects
Tooth-related jaw bone diseases can be divided in cysts and odontogenic tumors
The majority of cysts in the jaw bones are called odontogenic as they are derived from odontogenic epithelium that is related with the tooth development; only a few are nonodontogenic but have other kinds of epithelium as their source
Summary
Jaw bone differs from other bones in several aspects. It is unique due to its development from cells migrating from the embryonal neuroectoderm. With both unique features in the jaws, diseases occur that are not seen in any other part of the skeleton. For the purpose of this paper, these will be divided in 2 main groups: those related to the dentition and those restricted to the bone proper. Tooth-related jaw bone diseases can be divided in cysts and odontogenic tumors. Fibro-osseous lesions, giant cell lesions, and bone tumors are taken together as the main second group
