Abstract

Background: Dry socket is one of the most common complications following tooth extraction, though no studies have been made on its main risk factors in the primary healthcare services of Barcelona (Spain). Objectives: To analyze the influence of different factors upon the appearance of dry socket in patients attended in the primary care setting, and to determine the possible presence of risk factors in patients who have suffered a previous episode of dry socket.

Material and methods: During 24 months, questionnaires were filled with data on the patients seen in different public primary healthcare services in the area of Barcelona (Spain). A case-control study was conducted to identify the main risk factors for developing complications in the form of dry socket.

Results: A mandibular location of the extracted tooth, poor oral hygiene, difficult extraction, and previous dry socket increased the risk of developing this complication. In patients with dry socket in the past, the risk of developing the same complication again, adjusted for difficulty of extraction, was seen to increase 11.45-fold (OR: 11.45; 95%CI: 1.06 to 123.74; p = 0.045).

Conclusions: The risk factors for dry socket are a mandibular location of the extracted tooth, poor oral hygiene, difficult extraction, and particularly a history of dry socket in the past. The identification of these factors the prevention of dry socket in each patient could be improved. Key words:Dry socket, risk factors, extraction, complications.
