Dry Socket
🔹 Also called alveolar osteitis / alveolitis sicca dolorosa
🔹 Loss/disintegration of extraction socket clot → exposed bone
Pathogenesis
🔹 Due to fibrinolysis of clot
🔹 Plasmin dissolves fibrin clot
🔹 Severe pain + foul odor, but usually no pus
Risk factors
🔹 Traumatic/difficult extraction
🔹 Especially impacted mandibular 3rd molar
🔹 Women, smokers
🔹 Oral contraceptives (estrogen ↑ fibrinolysis)
🔹 Also seen with Paget disease or post-radiotherapy
Clinical features
🔹 Starts day 2–3 after extraction
🔹 Lasts about 7–10 days
🔹 Severe throbbing pain radiating to ear/neck
🔹 Bad odor / bad taste
🔹 Empty dry socket with exposed necrotic bone
🔹 May have low-grade fever and ipsilateral nodes
Management
🔹 Palliative only
🔹 Gentle irrigation
🔹 Obtundent dressing: ZOE or iodoform gauze
🔹 Change dressing until pain subsides
Prevention
🔹 Atraumatic extraction technique is most important
🔹 Routine socket antibiotics not routinely recommended
High-yield pearl
🔹 Post-extraction day 2–3 severe pain + empty socket + foul odor + no pus = dry socket
