Adjunctive use of platelet-rich fibrin in surgical treatment of furcation defects: A systematic review

Abstract

Periodontitis is an infectious disease characterized by the inflammatory destruction of the tooth supporting tissues. In multi-rooted teeth, this process leads to periodontal destruction within furcations creating defects demanding in terms of treatment. Regeneration of class II furcation involvement, although possible, is considered an unpredictable procedure, especially in terms of the bone fill. The interest in wound healing improvement by additional use of autologous concentrates of growth factors remains high in many fields of dentistry. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate and biomaterial. PRF forms a solid fibrin matrix, which is slowly remodeled comparable to the natural blood clot. Its utilization is associated with release of growth factors and glycoproteins over a long period of time. PRF activates alkaline phosphates, which show osteoblastic activity and this activation influences the bone formation.

The aim of this review of randomized controlled trials (RCTs) was to evaluate the adjunctive use of platelet-rich fibrin in surgical treatment of furcation defects.
