Title Risk of Developing Alveolar Osteitis Post-Operatively Following Dental Extraction is Positively Correlated to Smoking
Clinical Question Do smokers have an increased risk of developing alveolar osteitis following dental extractions as compared to healthy non-smokers?
Clinical Bottom Line Smoking is firmly connected to an increase risk of developing alveolar osteitis post operatively following dental extractions.

Comments on
The Evidence
This was a prospective nested case-control study. 1,355 patients participated in the study. 1,302 patients completed the study and 53 dropped out. 80 patients developed alveolar osteitis and were compared to 80 controls picked randomly from the group that didn’t develop alveolar osteitis (1,222). The comparison consisted of eight factors including the use of tobacco. Patient compliance was adequate. No competing interests were presented and recall bias is unlikely. Compelling connection between tobacco smoking following dental extractions and the development of alveolar osteitis was observed (odds ratio, 3.5; 95% confidence interval, 1.3 to 9.0)
Applicability Before an extraction, the surgeon must be aware that a patient who is a smoker has an increased chance of developing alveolar osteitis so preventative measures can be taken.
