Incidence and treatment of complications in patients who had third molars or other teeth extracted

The aim of this study was to compare the incidence of complications after extraction of third molars (M3) or other teeth, and to describe their management. We made a retrospective cohort study of patients having M3 or other teeth extracted, and recorded complications up to two years' follow-up. A total of 142 complications developed after 2355 procedures (6%) – 7% after extraction of M3 compared with 5% after extractions of other teeth (p=0.024). The three most common complications were wound infection (2%), pain without apparent cause (<1%), and oroantral communication (<1%).
