Platelet-rich fibrin added to deep tooth cleaning for periodontitis

Official title: Platelet Rich Fibrin Adjunctive to Non-surgical Periodontal Therapy: a 6-month Split-mouth Randomized Controlled Clinical Trial

Run by University of Bern · NCT07013682 · Data updated 2026-11-12

This will try adding platelet-rich fibrin (PRF) to deep non-surgical cleaning to see if it improves gum healing and attachment in adults with stage II–IV periodontitis.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 and over with generalized stage II–IV periodontitis who have at least 20 teeth and are willing to undergo venipuncture and follow-up visits are ideal candidates.

Probably not a fit

People who recently had periodontal treatment or antibiotics, who are pregnant or receiving cancer treatment, or who cannot have blood drawn are excluded and unlikely to benefit from participation.

What this trial studies

This interventional split-mouth trial compares scaling and root planing (SRP) alone versus SRP plus a PRF membrane applied to treated sites in adults with generalized stage II–IV periodontitis. Clinical outcomes include probing pocket depth, clinical attachment level, plaque and gingival indices, and gingival recession measured at baseline, 7 days, 3 months, and 6 months, with additional assessment of patient-reported pain, bacterial profiles, and inflammatory markers. Participants must have at least 20 teeth and will receive full-mouth non-surgical treatment with PRF applied to one side and SRP alone on the other side. The design tests whether the autologous PRF scaffold can slow epithelial migration and enhance periodontal healing compared with SRP alone.

Why it matters

Potential benefit: If successful, adding PRF could increase clinical attachment gain and reduce pocket depth after non-surgical therapy, helping preserve teeth and improve gum health.

How similar studies have gone: Smaller trials and case series have reported improved healing with PRF in periodontal procedures, but results are mixed and high-quality randomized evidence is still limited.
