Prevalence and factors associated with SSI after minor oral surgery
Objectives: Antimicrobial resistance (AMR) has become a global problem, and many countries are working on AMR countermeasures. In Japan, this problem is also being actively addressed, but there is still much room for improvement in the appropriate use of antimicrobial agents in dental practice. The purpose of this study was to clarify the surgical site infection (SSI) rate after tooth extraction, and to identify factors associated with an increased risk of SSI after tooth extraction.
Methods: A retrospective study was conducted on the medical records of patients who underwent tooth extraction over a 10-year period (2013-2022) at the study hospital. Patient background and factors related to SSI were extracted from the medical records. Multivariate analysis using binomial logistic regression analysis were performed for each factor, with the presence of SSI as the dependent variable.
Results: A total of 4,889 cases were included, including both ordinary and wisdom tooth extraction. There were 118 cases (2.4%) of SSI occurrence. The variable that significantly influenced the occurrence of SSI were the expertise of the surgeon (odds ratio: 9.93; p<0.05) and the complexity of the extraction (odds ratio: 4.4; p<0.05). The type and duration of antibiotics did not significantly affect the occurrence of postoperative infection.
Conclusions: The risk of SSI in tooth extraction was low and excessive antibiotic prescription was considered unnecessary.
