What is a true statement regarding localized alveolar osteitis?

Localized alveolar osteitis, often referred to as dry socket, is primarily characterized by the loss of the blood clot at an extraction site, leading to exposed bone and subsequent inflammation. The underlying cause of this condition is indeed linked to excessive fibrinolysis, meaning that the normal clotting process is disrupted, allowing for the breakdown of the clot too soon after tooth extraction. This premature dissolution creates an environment where the bone is exposed, leading to inflammation and significant pain.

The other statements do not align with established understanding of localized alveolar osteitis. While the incidence of dry socket can vary between the mandible and maxilla, it is often higher in the mandible. Prophylactic antibiotics do not significantly lower the incidence of this condition since dry socket is largely related to local factors rather than systemic infection. Additionally, while pain is a hallmark symptom of localized osteitis, it does not always necessitate surgical intervention; management may involve conservative approaches such as analgesics and irrigation, depending on the severity of the case. Therefore, identifying excessive fibrinolysis as a key factor in localized alveolar osteitis accurately reflects current knowledge in dental practice.
