Study Notes
Infections of the Jaws
- This presentation covers infections of the jaws, including tooth extraction healing and complications such as dry socket and osteomyelitis.
Tooth Extraction Healing
- Healing after tooth extraction follows a phase-wise process.
- Phase 1 (Immediate): A blood clot fills the extraction socket.
- Phase 2 (2 weeks): The clot retracts and stabilizes.
- Phase 3 (3 weeks): Granulation tissue fills the socket.
- Phase 4 (6-8 weeks): Complete healing, with bone replacement.
Alveolar Osteitis (Dry Socket)
- It is a painful complication of tooth extraction.
- Not an infection; rather, exposure occurs from a lost blood clot.
- Risk factors include excessive extraction trauma, limited blood supply, certain medications, smoking, and extraction of lower third molars.
- Symptoms include severe pain, and bad taste from pus draining to the mouth through sinuses.
Etiological Factors of Dry Socket
- Excessive extraction trauma
- Limited local blood supply
- Gingival infection (gingivitis, pericoronitis, abscess)
- Local anesthetics with vasoconstrictors
- Smoking
- Oral contraceptives
- Osteosclerotic diseases (Paget's disease, cemento-osseous dysplasia)
- Radiotherapy
- History of previous dry socket
Osteomyelitis of the Jaws
- Bacteria and inflammation spread through the medullary bone from a focus of infection
- Local origin, not blood-borne infection.
- Classified as suppurative or sclerosing.
- Acute osteomyelitis is characterized by deep bacterial invasion into medullary and cortical bone and rapidly develops over weeks.
- Chronic osteomyelitis develops slowly over months to years and has a less aggressive inflammatory response.
Acute Osteomyelitis
- Potential sources of infection include periapical infections, pericoronitis, fractures through periodontal pockets, acute necrotizing gingivitis, or penetrating, contaminated injuries.
Factors predisposing to Osteomyelitis
- Focal factors: Decreased vascularity/vitality of bone (trauma, radiation, Paget's, osteoporosis)
- Systemic factors: Impaired host defense (immune deficiency/suppression, DM/malnutrition, age)
Chronic Osteomyelitis
- More common than acute osteomyelitis, typically arising from weakly virulent bacteria.
- Can develop without an initial acute phase.
- Sclerosis or irradiation increase risk.
Clinical features of Chronic Osteomyelitis
- Persistent ache or pain, often relapsing
- Bad taste from pus draining to the mouth through sinuses
- Swelling, increased pain and discharge
- Increased tooth mobility
- Exposed bone
Radiographic Features of Chronic Osteomyelitis
- Often contains radiopacities (sequestra)
- Variable radiographic appearances (patchy, poorly defined radiolucency and sclerosis)
- May resemble a malignant neoplasm
Complications
- Pathological fracture
- Chronic osteomyelitis
- Cellulitis
- Septicemia
