ObjectiveTo evaluate the complication rates for third molar extractions based upon resident level within an OMFS program, and identify the risk factors associated with postoperative complications following third molar extractions.Study DesignRecords of 1,992 subjects (5,466 third molar extractions) over a 5-year period were reviewed. The data was collected using appropriate CDT codes from July 1, 2011 – June 30, 2016. The cases were analyzed using demographic statistics, Pearson Chi-square test, and regression analysis.Results1,855 patients had sufficient data available for analysis and inclusion in the study. There were 146 adverse outcomes. The common complication was alveolar osteitis. Nerve injuries and retained root tips were encountered less frequently. There was a significant association between the depth of impaction and developing a postoperative complication. There was a direct correlation between the level of resident training and the likelihood of an adverse outcome.ConclusionThe study indicates that there are identifiable risk factors associated with postoperative complications following third molar extraction in an OMFS residency program. These factors include location, depth of impaction, use of a surgical drill, and level of resident training, which are correlated directly with the development of negative outcomes following third molar extractions.
