Platelet-Rich Fibrin in the Treatment of Multiple Gingival Recessions

At the test sites, the previously prepared PRF was positioned over the recession defects, the coronal margin of the PRF was placed at the CEJ

Split-full-split thickness flap incisions were performed in a coronal-apical direction. The papillae adjacent to the involved tooth were de-epithelialized to create a connective tissue bed. The gingival flap was repositioned without tension, with its margin located on the enamel, on the test and control sides. It was held in that position with 5-0 resoble sutures
