Using injectable platelet-rich fibrin with bovine bone grafts to treat intrabony periodontal defects

Evaluation of the Effect of Injectable Platelet-Rich Fibrin in the Treatment of Periodontal Intrabony Defects With Xenogenic Grafts: a Randomized Controlled Clinical Trial

Not applicable Interventional Saglik Bilimleri Universitesi · NCT07146776

This will try adding injectable platelet-rich fibrin (i-PRF) to bovine bone grafts to see if adults with stage III periodontitis and intrabony defects heal better than with grafts alone.

What this trial studies

Adults with stage III periodontitis and interproximal intrabony defects will undergo open flap debridement and receive either bovine-derived xenogenic bone graft mixed with i-PRF or the same graft mixed with saline. Clinical measures (for example probing pocket depth and defect area) and radiographic bone fill will be recorded and compared between the two groups. The aim is to determine whether i-PRF increases bone fill and reduces defect size versus graft alone. Findings will show whether adding this tissue-friendly biologic improves commonly used bovine xenograft outcomes for intrabony defects.

Who should consider this trial

Good fit: Adults aged 18–65 with stage III periodontitis who have interproximal 2- or 3-walled intrabony defects ≥3 mm and persistent probing depths ≥5 mm after initial therapy, and who are non-smokers or light smokers (≤10 cigarettes/day).

Not a fit: People with single-walled defects, uncontrolled systemic disease (such as uncontrolled diabetes), heavy smokers, those recently on antibiotics or with recent periodontal surgery, and pregnant or breastfeeding patients are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, adding i-PRF could increase bone fill and reduce pocket depths and defect size, improving periodontal healing after surgery.

How similar studies have performed: Previous studies combining PRF derivatives with various graft materials have shown promising results, but the specific combination of i-PRF with bovine-derived xenograft for intrabony defects has not been studied before.
