Role of platelet-rich plasma in soft tissue root-coverage procedures: A review

The aim of this article was to review the current evidence on the role of platelet-rich plasma (PRP) in enhancing root-coverage techniques and discuss the rationale for its use in these applications. Sound biologic rationale and a multitude of basic science research support the use of PRP to promote soft tissue healing, although evidence of its role in enhancing periodontal applications, especially root coverage, is limited. Current scientific research has yet to elucidate all of the mechanisms by which PRP can affect soft tissue healing and assess its capacity to stimulate regeneration. Furthermore, clinical evidence on the use of PRP in root-coverage procedures is extremely limited, with only 2 randomized controlled trials published as of May 2007. A pertinent review of medical and dental literature relating to PRP and its role in wound healing and enhancement of root-coverage procedures was performed. Preliminary reports in this area suggest that the potential benefits of PRP in root-coverage procedures may be improved esthetics, decreased patient morbidity, and accelerated wound healing. An appropriate assessment of the effects of PRP and its possible use in enhancing root-coverage procedures cannot be made at this time because of inadequate clinical evidence.
