title: Risk of wound infection and safety profile of amoxicillin in healthy patients which required third molar surgery: a systematic review and meta-analysis.
abstract: The aim of this systematic review and meta-analysis was to assess the risk of surgical wound infection and the adverse effects of amoxicillin in healthy patients who required excision of third molars. We identified eligible reports from searches of PubMed, Medline®, the Cochrane Library, Imbiomed, LILACS, and Google Scholar. Studies that met our minimum requirements were evaluated using inclusion and exclusion criteria and the Oxford Quality Scale. Those with a score of 3 or more on this Scale were included and their data were extracted and analysed. For evaluation of the risk of infection the absolute risk reduction, number needed to treat, and 95% CI were calculated. For evaluation of the risk of an adverse effect the absolute risk increase, number needed to harm, and 95% CI were calculated using the Risk Reduction Calculator. Each meta-analysis was made with the help of the Mantel-Haenszel random effects model, and estimates of risk (OR) and 95% CI were calculated using the Review Manager 5.3, from the Cochrane Library. A significant risk was assumed when the lower limit of the 95% CI was greater than 1. Probabilities of less than 0.05 were accepted as significant. The results showed that there was no reduction in the risk of infection when amoxicillin was given before or after operation compared with an untreated group or placebo. In conclusion, this study suggests that amoxicillin given prophylactically or postoperatively does not reduce the risk of infection in healthy patients having their third molars extracted.
