BACKGROUND: The aim of this study to evaluate the contributions of titanium-prepared platelet-rich fibrin (T-PRF) combined with open flap debridement (OFD) on biological markers in gingival crevicular fluid (GCF)and periodontal outcomes. METHODS: Twenty-nine participants with chronic periodontitis were treated either with autologous T-PRF+OFD or OFD alone. GCF growth factor levels and relative receptor activator nuclear factor kappa-B/osteoprotegerin (RANKL/OPG) ratio at baseline and 2, 4, and 6 weeks postoperatively were analyzed, and clinical parameters such as probing depth (PD), relative attachment level (RAL) and gingival margin level (GML) at baseline and 9 months after surgery were compared. RESULTS: The mean PD reduction, RAL gain, and GML change were significantly greater in the OFD+T-PRF sites than in the OFD sites (P = 0.033, P = 0.029, and P = 0.026, respectively). Both groups demonstrated increased growth factor levels at week 2 compared with baseline, followed by reductions at weeks 4 and 6. GCF growth factor levels in the test group were seen at higher concentrations with respect to control group until 6 weeks post-surgery. During this 6-week period, relative RANKL/OPG ratio was found significantly lower in the OFD+T-PRF group compared to the OFD group(P < 0.05). CONCLUSIONS: Using T-PRF membrane combined with OFD provided significantly higher concentrations of growth factors and lower RANKL/OPG ratio in GCF for approximately 4 to 6 weeks, and improved periodontal healing compared to conventional flap sites.
