Osteomyelitis
Osteomyelitis
An infection of the bone causing inflammation, bone necrosis and possible sequestration.
Why does osteomyelitis mainly occur in the mandible?
Why does osteomyelitis mainly occur in the mandible?
The mandible has a limited blood supply compared to the maxilla, making it more susceptible to osteomyelitis.
What leads to further necrosis in osteomyelitis?
What leads to further necrosis in osteomyelitis?
The inflammatory exudate from acute inflammation can further damage the bone and lead to necrosis in osteomyelitis.

Study Notes
Osteomyelitis
- Osteomyelitis mainly occurs in the mandible due to its poorer blood supply and compact bone structure, making it more prone to infection.
Progression of Osteomyelitis
- Further bone necrosis in osteomyelitis is led by the formation of a sequestrum, which is a piece of dead bone that has become separated from healthy tissue.
Characteristics of Osteomyelitis
- The term for the dead bone separated from healthy tissue in osteomyelitis is sequestrum.
Etiology of Osteomyelitis
- The main cause of osteomyelitis is bacterial infection, often resulting from a dental infection or trauma.
Pathophysiology of Osteomyelitis
- The process that involves new bone formation in osteomyelitis is called involucrum.
