Effects of Platelet Concentrates on Palatal Wound Healing

Summary

Platelet concentrates used in palatal wound healing have been reported to accelerate wound healing and reduce postoperative patient discomfort. The use of elet platelet rich fibrin '(PRF) in the palatal donor site after FGG surgery has been shown to provide significant benefits in terms of wound healing parameters and postoperative comfort. In a study using a platelet rich plasma (PRP) with a different platelet concentration, PRP was found to accelerate wound healing and shorten the healing time. In another study using titanium-prepared platelet rich fibrin (T-PRF) for palatal wound healing, it accelerated the wound healing process and reached the initial level of soft tissue thickness in the donor region at the end of 6 months. In the literature, there are few studies using platelet concentrates in palatal wound healing and only some concentrates (PRP, PRF, T-PRF) are used. The aim of this study is to compare the effects of injectable platelet rich fibrin (i-PRF), which are autologous fibrin glue (AFG) and injectable platelet concentrates, on palatal wound healing. The findings obtained from this study will contribute to the literature in determining the product and method that will provide optimal postoperative patient comfort and wound healing.

Interventions

BIOLOGICAL

AFG application on palatinal wound healing

9 ml venous blood collected from the patient was transferred to the tube without any anticoagulants. In the protocol, venous blood collected in the tube was centrifuged for 2 minutes at 2700 rpm (approximately 692 g) in a special centrifuge (Medifuge, Silfradent, Italy) to obtain two layers: the lower layer of red blood cells and the upper layer of AFG. The AFG at the top of the tube was collected by means of an injector and transferred to the metal godet. It was held for 15-20 minutes for polymerization. After polymerization occurred, the polymerized AFG in the metal gum was applied to the wound surface in the donor site . No suture or tissue glue was used. Adhesive properties of AFG were utilized.

BIOLOGICAL

i-PRF application on palatinal wound healing

10 ml venous blood collected from the patient was transferred to the tube without any anticoagulants. Based on G force, collected venous blood were centrifuged at 2300 rpm (about 241 g) in a centrifuge (PC-O2, Process for PRF, Nice, France) for 3 minutes to obtain two layers: The two layers are the lower layer of red blood cells and the upper layer of i-PRF. The i-PRF at the top of the tube was collected with a syringe and transferred to the metal godet. It was held for 20-25 minutes for polymerization. After the polymerization, the polymerized i-PRF was applied to the wound surface in the donor site. No suture or tissue glue was used. Adhesive properties of AFG were utilized.
