Over the years, numerous surgical techniques such as free autografts and pedicle grafts have
been introduced to correct gingival recession defects. Combination grafts with either
autografts or allografts, and newer concepts of guided tissue regeneration (GTR), platelet
concentrates, etc., were developed more recently to correct mucogingival defects. The use of
PRF in various surgical procedures such as degree II furcations, intrabony defects, sinus
floor segmentation during implant placement and on facial plastic surgeries have shown
promising results. However to our knowledge, till this study was completed, no studies have
been reported with the clinical outcomes of autologous platelet rich fibrin membrane for the
treatment of localized gingival recession defects.
Hence, this study was designed to compare coronally advanced flap with platelet rich fibrin
membrane versus subepithelial connective tissue graft in treatment of Miller's Class I and
Class II gingival recession defects.
