Treatment of Miller I Mandibular Gingival Recessions Using PRF vs. Connective Graft

Figure 1

PRF collection. A blood sample was obtained in 10 ml plastic tubes without anticoagulant and no activator. Immediately, the tubes were centrifugated at 3000 rpm for 10 minutes (Scilogex DM1536). The fibrin clot was removed from the tube and separated by microsurgical scissors. The PRF membrane was pressed into a calibrated metal box that forms membranes at a constant thickness of 1 mm. Two membranes of PRF were superimposed and immediately taken into the surgical site.
