Effect of Injectable Platelet-rich Fibrin (i-PRF) on Wound Healing After Gingivectomy

This study evaluates the clinical and biochemical effects of injectable platelet-rich fibrin (i-PRF) on wound healing after gingivectomy, a surgical procedure used to treat gingival overgrowth. Using a split-mouth design, i-PRF was applied to the surgical site on one side of the mouth (test group), while the other side was treated with conventional gingivectomy alone, without any additional material (control group). Clinical periodontal parameters (plaque index, gingival index, probing depth, clinical attachment level, and bleeding on probing) were assessed at baseline, before surgery, and 28 days after surgery. Additionally, levels of PDGF, IGF-1, and IL-18 in gingival crevicular fluid were measured before surgery and on the third postoperative day to evaluate the biochemical impact of i-PRF on wound healing. A total of 31 participants aged 15-50 years were included in the study.
