The clinical impact of platelet-rich fibrin (PRF) and plasma rich in growth factors (PRGF®) respectively has been studied extensively in the field of regenerative dentistry during the last two decades. Literature supports evidence for additional benefits in regenerative periodontal therapy, alveolar ridge preservation, management of extraction sockets, implantology including guided bone regeneration as well as defect management in oral surgery. Regarding gingival wound healing and soft tissue regeneration, there is sufficient evidence for their positive effects which have been confirmed in several systematic reviews. The effects seem less clear in conjunction with osseous regenerative treatments, where the inter-study heterogenity in terms of different PRF-protocols, indications and application forms might hinder a systematic comparison. Nevertheless there is evidence that PRF might have beneficial effects on hard-tissue or its regeneration respectively.For being able to facilitate conclusions in systematic reviews, precise reporting of the used PRF-protocols is mandatory for future (clinical) research in the field of autologous platelet concentrates.
