Titanium Prepared Platelet Rich Fibrin for Multiple Gingival Recessions

Objective: Titanium-prepared platelet-rich fibrin (T-PRF) is activated with titanium, which results in a more mature and aggregated form than PRF. In our previous studies, we established that the fibrin carpet formed with titanium had a firmer network structure, and longer resorption time in the tissue than the fibrin carpet formed with glass. The purpose of this randomized controlled clinical trial is to compare the effects of autogenous T-PRF and CTG. Materials and methods: A total 114 Miller Class I/II gingival recessions with abrasion defects will be treated either T-PRF (63 teeth) or CTG (51 teeth) using a modified tunnel technique. Clinical periodontal indexes, keratinized tissue (KTW), gingival thickness (GT) and recession depth (RD) will be recorded before surgery and at 6 and 12-month follow-up examinations. The Visual Analog Scale and healing index scores will be assessed.
