| Abstract: | 1 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. 2 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. 3 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). 4 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. |
