ObjectivesThe use of antibiotics to prevent dry socket and infection is a controversial but widespread practice. The aim of the study is to assess the efficacy of systemic antibiotics in reducing the frequencies of these complications after extraction.Study DesignA systematic review and meta-analysis, according to the PRISMA statement, based on randomized double-blind placebo-controlled trials evaluating systemic antibiotics to prevent dry socket and infection after third molar surgery. Databases were searched up to June 2015. Relative risks (RRs) were calculated with inverse variance-weighted, fixed-effect, or random-effect models.ResultsWe included 22 papers in the qualitative and 21 in the quantitative review (3304 extractions). Overall-RR was 0.43 (95% confidence interval [CI] 0.33-0.56; P < .0001); number needed to treat, 14 (95% CI 11-19). Penicillins-RR: 0.40 (95% CI 0.27-0.59). Nitroimidazoles-RR: 0.56 (95% CI 0.38-0.82). No serious adverse events were reported.ConclusionsSystemic antibiotics significantly reduce the risk of dry socket and infection in third molar extraction.
