Background: Other than releasing a bunch of growth factors and molecules, platelet concentrates (PCs), especially platelet-rich fibrin (PRF) has a potential role in antimicrobial activities. Aim: The aim of this present systematic review was to collect, evaluate, and compare the available evidence regarding the antimicrobial efficacy of all types of PRF and to highlight the underlying mechanisms along with their potential benefits based on their actions, investigated by clinical and in vitro studies. Materials and Methods: Systematic approach was followed in the selection of studies. A detailed search was done in electronic databases such as PUBMED/MEDLINE, GOOGLE SCHOLAR, and SCIENCE DIRECT using specific search items with language restricted to English. All in vitro studies and clinical studies which assessed the antimicrobial activity of PRF alone or along with antibiotics or a type of PRF were included in the study. Other studies which included antimicrobial effects of other forms of PCs such as platelet-rich plasma (PRP), platelet gel, and animal studies were all excluded from the study. Results: After the initial and final screening of articles, only eight met the required criteria, of which seven were in vitro studies and one was a clinical study. All the studies evaluated the efficacy of one or more forms of PRF either against bacterial pathogens or showed inhibition of growth in culture. Conclusion: Based on the systematic review, PRF possesses antimicrobial efficacy against pathogens and the exact mechanism of the antimicrobial efficacy needs further investigation. The enhanced property of PRF against pathogens might be due to the release of platelets and preparation protocols such as lesser time and centrifugal speed. Further, PRF should be considered to be used as local drug delivery system which will be a potential treatment against periodontopathogens in the future.
