DISORDERS OF MAXILLA AND MANDIBLE

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
