OSTEOMYELITISDefinition: 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.
MAJOR INFECTIONS OF JAWS
ACUTE OSTEOMYELITIS
CHRONIC OSTEOMYELITIS
GARRE OSTEOMYELITIS
TYPES OF OSTEOMYELITIS
DEFINITIONA rapidly destructive inflammatory process within
bone that consist of Granulation tissue, Purulent exudate and islands of non-vital bone
(sequestra)
ACUTE OSTEOMYELITIS
1. Untreated periapical abcess
2. Minor traumatic incident involving a mandible that has its blood supply compromised by previous high doses of radiation for the treatment of malignancy( OSTEORADIONECROSIS)
CAUSES 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
CLINICAL FEATURES OF ACUTE 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
RADIOGRAPHIC FEATURES OF OSTEOMYELITIS
• Persistent low grade infection associated with bone destruction and Granulation tissue formation with little suppuration
CLINICAL FEATURES:• Persistent ache / pain with exposed bone
CHRONIC OSTEOMYELITIS
TREATMENT:• Antibiotics
TREATMENT
• 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
GARRE OSTEOMYELITIS
Radiographic appearance:• onion skin appearance
TREATMENT: Identification of source of
infection Extraction of the tooth
involved in infection Surgical treatment of tissues in molar area
