Preventing Dry Socket
Preventing Dry Socket
Maintaining a clean surgical site and following postoperative instructions can prevent dry socket.
Treatment for Dry Socket
Treatment for Dry Socket
Irrigating the socket with antiseptic or saline solution, and placing an antiseptic dressing to remove debris and prevent further contamination are standard treatments.
Dry Socket Symptoms
Dry Socket Symptoms

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
