osteomyelitis of the jaws
Osteomyelitis of the jaws is osteomyelitis (which is infection and inflammation of the bone marrow, sometimes abbreviated to OM) which occurs in the bones of the jaws (i.e. maxilla or the mandible). Historically, osteomyelitis of the jaws was a common complication of odontogenic infection (infections of the teeth). Before the antibiotic era, it was frequently a fatal condition.
==Classification==
The classification is similar to the classification of OM generally, according to the length of time the inflammation has been present and whether there is suppuration (the formation of pus). ''Acute osteomyelitis'' is loosely defined as OM which has been present for less than one month and ''chronic osteomyelitis'' is the term used for when the condition lasts for more than one month. Suppurative osteomyelitis of the jaws is uncommon in developed regions, and more common in developing countries. In Europe and the United States, most cases follow dental infections or mandibular fractures. There have been many reported cases occurring in Africa which are coexistent with acute necrotizing ulcerative gingivitis or cancrum oris.
In the pre-antibiotic era, acute OM of the jaws was more extensive. Massive, diffuse infections commonly involved the whole side of the mandible, or the whole of one side and the opposite side as far as the mental foramen. Localized osteomyelitis tended to be described as either ''vertical'', where a short segment of the body of the mandible from the alveolar crest to the lower border was involved, and ''alveolar'', where a segment of alveolar bone down to the level of the inferior alveolar canal would sequestrate, including the sockets of several teeth. Treatment with antibiotics has significantly altered the natural history of OM of the jaws.
