|
Location if the infection
|
- Most often the facial swelling and the facial space involvement comes from an infection of the pulp of the tooth
|
|
|
Spreading of the infection
|
The odontogenic infections can spread vi many mechanisms : direct extension, lymphatic spreading, hematologic spreading, ingestion (rare cause of HCl degradation in the stomach), aspiration
|
|
|
Outcome of the infection
|
- The outcome of the infection depends of the following factors : the virulence of the organism, the host's resistance, the anatomical pathway of the spread
|
|
|
Routes of spreading
|
- Dentoalveolar abscess : Drains into the oral cavity and the skin and tracks into deeper fascial plans and spaces
- Infraorbital space : Eye swelling via spreading through the cavernous sinus - Buccal space : cause cheek swelling - Sublingual space : causes an elevation of the tongue and of the mouth floor while communicating with the submandibular space - Submandibular space : presents as a firm, ill defined swelling below the anterior border of the mandible, tender |
|
|
Ludwig's angina
|
- Aggressive rapidly spreading cellulitis involving: bilateral submandibular spaces, bilateral sublingual spaces and the submental space
- EMERGENCY situation because of the airway obstruction produced by it |
|
|
Progression of the infection
|
- Acute pulpitis
- Inflammation - Cellulitis in the pulp - Abscess in the pulp - Cellulitis or abscess in the peri-apical area - Cellulitis or abscess or the surrounding tissues |
|
|
Clinical features
|
- Pain
- Swelling - Warmth - Loss of function - Redness |
|
|
Development of the infection
|
- Inoculation
- Cellulitis (1-2 days) - Abscess (2-3 days) - Resolution |
|
|
Treatment
|
- Patient care : airway management, medical problems, rest and nutrition, localization, fever
- Specific therapy : root canal treatment or extraction, incision and drainage - Antibiotic therapy (depends of the stage) : cellulitis (aerobic bacterias), abscess (anaerobic bacterias) |
