A
- Infection and inflammation of the bone and bone marrow
- Acute or chronic
- Varied aetiology
2
Q
Etiological factors of osteomyelitis in the jaw bone
A
- Infantile Osteomyelitis=>Perinatal trauma
- Chronic Diffuse Sclerosing Osteomyelitis=> Hyperactive immunological response
- Garre’s Sclerosing Osteomyelitis=>Over-inflammatory reaction in the periosteum
- Traumatic Osteomyelitis=>Open fractures leading to multiple bacterial infections
3
Q
Clinical features of infantile osteomyelitis
A
- Swelling of the face=> edema of the eyelids
- Subperiosteal abscesses=> alveolar mucosa and palate
- Systemic signs=> Fever
4
Q
Complications associated with infantile osteomyelitis
A
- Spread to the eye and brain

- Serious damage to jaw growth
- Loss of teeth and bone
5

- Antibiotics =>penicillin and clindamycin recommended
6
Q
Clinical features of chronic diffuse sclerosing osteomyelitis
A
- Recurrent pain and swelling
- No suppuration or abscess formation
- Intermingled sclerotic and osteolytic lesions
7
Q
Treatment for chronic diffuse sclerosing osteomyelitis

8
Q
Clinical features of Garre’s sclerosing osteomyelitis
A
- Localized, unilateral, hard mandibular swelling=> Little tenderness
- Episodic pain w/ dormant periods
- Facial asymmetry
9
Q
Treatment for Garre’s sclerosing osteomyelitis
A
- Elimination of the cause of infection =>
- Tooth extraction or endodontic treatment
10
Q
How traumatic osteomyelitis is classified
A
- Stage 1=>Medullary osteomyelitis (confined to the medullary cavity)
- Stage 2=>Superficial osteomyelitis (involves only the cortical bone)
- Stage 3=> Localized osteomyelitis (involves both cortical and medullary bone)
- Stage 4=> Diffuse osteomyelitis (involves entire thickness of the bone with loss of stability)
11
Q
