About
Subepithelial connective tissue graft (SCTG) has greater predictability for root coverage and causes minimal discomfort to patient. Although donor site heals with primary intention causing less scar tissue, in some different harvesting procedures primary flap closure may not be achieved due to nature of thick palatal tissues. Some potential complications may occur at donor site such as: necrosis of graft and palatal site, pain, excessive hemorrhage, protracted discomfort, donor site infection and in some cases donor site paresthesia. Platelet rich fibrin (PRF) is a platelet concentrate obtained by a simple procedure that does not require biochemical blood involvement.Based on the known biological effects of PRF, the aim of this study is to evaluate the PRF in the management of soft tissue donor sites in term of bleeding and pain sensation, and to observe the changes in tissue healing after a subepithelial connective tissue graft procedure at palatal donor site.
Full description
Successful treatment of gingival recession (GR) is based on the use of clinically predictable periodontal plastic surgery (PPS) procedures. There are many procedures and different surgical procedures were proposed. Coronally advanced flap and subepithelial connective tissue graft (SCTG) is a good combination to increase the keratinized tissue width and reduce the amount of gingival recession.
SCTG has greater predictability for root coverage and causes minimal discomfort to patient. Although donor site heals with primary intention causing less scar tissue, in some different harvesting procedures primary flap closure may not be achieved due to nature of thick palatal tissues.
Some potential complications may occur at donor site such as: necrosis of graft and palatal site, pain, excessive hemorrhage, protracted discomfort, donor site infection and in some cases donor site paresthesia.
Platelet rich fibrin (PRF) is a platelet concentrate obtained by a simple procedure that does not require biochemical blood involvement. The three-dimensional fibrin network and presence of many growth factors such as fibroblast growth factor, platelet-derived growth factor (PDGF) and epidermal growth factor supports effective neovascularization, accelerated wound closure and rapid cicatricial tissue remodeling. The strong fibrin architecture distinguishes it from other kinds of platelets concentrates and it seems responsible for the slow release of growth factors over a period of 7-14 days5. This period is seen as sufficient to prevent complications after connective tissue graft. Since the first description by Choukroun in 2000, PRF has been used in the clinical field for more than a decade in oral surgery and implant dentistry.
Based on the known biological effects of PRF, the aim of this study is to evaluate the PRF in the management of soft tissue donor sites in term of bleeding and pain sensation, and to observe the changes in tissue healing after connective tissue graft procedure at palatal donor site.
