Regarding alveolar osteitis (dry socket), which of the following statements is NOT true?

Alveolar osteitis results from premature dissolution of the post-extraction blood clot, likely through fibrinolysis, which exposes the underlying alveolar bone to oral bacteria and debris. Risk factors include smoking, oral contraceptive use (estrogen increases fibrinolytic activity), difficult extractions, mandibular posterior teeth, poor oral hygiene, and pre-existing infection. The exact etiology is multifactorial and is NOT always easily identified in every case — multiple predisposing factors interact, making a single definitive cause difficult to pinpoint. Oral contraceptives and fibrinolysis are both established associations.
