Effects of Platelet Concentrates on Palatal 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.

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.
