3. MAJOR INFECTIONS OF JAWS
OSTEOMYELITIS Definition: An inflammatory process within medullary ( trabecular) bone that involves the marrow spaces Osteomyelitis of jaws is mainly a disease of adults with several potential sources of infection.

4. TYPES OF OSTEOMYELITIS
ACUTE OSTEOMYELITIS
CHRONIC OSTEOMYELITIS
GARRE OSTEOMYELITIS

5. ACUTE OSTEOMYELITIS
DEFINITION A rapidly destructive inflammatory process within bone that consist of Granulation tissue, Purulent exudate and islands of non-vital bone (sequestra)

6. CAUSES OF ACUTE OSTEOMYELITIS
Untreated periapical abcess
Minor traumatic incident involving a mandible that has its blood supply compromised by previous high doses of radiation for the treatment of malignancy( OSTEORADIONECROSIS)

7. CLINICAL FEATURES OF ACUTE OSTEOMYELITIS
Infection of mandible
Early complaints are Severe, Throbbing pain and swelling
Later distension of periosteum with pus occurs
Finally, subperiosteal bone formation causes the swelling to become firm
Associated teeth are tender and mobile
Overlying gingiva is red, swollen and tender
Regional lymph nodes are enlarged and tender

8. RADIOGRAPHIC FEATURES OF OSTEOMYELITIS
Ill-defined margins with fluffy and moth-eaten appearance
TREATMENT:
Surgical treatment to
establish drainage of
purulent exudates
Use of antibiotics to kill the
microorganisms involved

9. CHRONIC OSTEOMYELITIS
Persistent low grade infection associated with bone destruction and Granulation tissue formation with little suppuration
CLINICAL FEATURES:
Persistent ache / pain with exposed bone

10. TREATMENT
TREATMENT:
Antibiotics

11. GARRE OSTEOMYELITIS
It is an unusual hyperplasic reaction of the periosteum that is unique to young patients
CLINICAL FEATURES:
associated with advanced acute caries in young patients
Occurs when free gingival margin remain above the height of contour of tooth results in food impaction

12. RADIOGRAPHIC APPEARANCE AND TREATMENT
onion skin appearance
TREATMENT:
Identification of source of
infection
Extraction of the tooth
involved in infection
Surgical treatment of tissues in molar area
