Which statement is NOT true about alveolar osteitis (dry socket)?

Alveolar osteitis (dry socket) is a postoperative complication characterized by partial or complete loss of the blood clot from the extraction socket, resulting in exposed alveolar bone and severe pain. Its etiology is multifactorial — there is no single, easily identified cause. Contributing factors include: excessive fibrinolysis, bacterial contamination, smoking, use of oral contraceptives (elevated estrogen), difficult extractions with excessive trauma, poor oral hygiene, and mandibular molar location. It occurs in approximately 2–5% of routine extractions and up to 20% of mandibular third molar extractions. Treatment involves gentle irrigation and placement of a medicated dressing (usually containing eugenol).
