Abstract

Aim: This systematic review and meta-analysis aimed to assess individually the regenerative potential of PRF (Platelet-rich Fibrin), PRP (Platelet-rich Plasma), and PRGF (Plasma Rich in Growth Factors) in comparison to OFD (Open Flap Debridement) alone for treating Intrabony defects, by calculating pooled effect sizes.

Background: Relevant randomized controlled trials on humans were searched in PUBMED, COCHRANE CENTRAL, and GOOGLE SCHOLAR. Mean differences (MD) of Clinical Attachment level (CAL), Probing Pocket depth (PPD), and Defect Depth Reduction (DDR) between the Experimental and Control groups were used for calculating pooled effect sizes. Risk of bias was assessed using Cochrane's tool, and publication bias was evaluated through Funnel plots, Trim & Fill Method, and Rosenthal's Fail-Safe N Test.

Review result: A total of 23 studies were identified for qualitative and quantitative analysis. These studies were categorized into PRF, PRP, and PRGF groups based on the type of APC used. PRF showed the highest CAL gain (1.60 mm, 95% CI = 0.963-2.232 mm, P < 0.001, I2 = 93.83%) and PPD reduction (1.76 mm, 95% CI = 1.056 to 2.446, P < 0.001, I2 = 96.05%). However, PRP exhibited the greatest DDR (3.42 mm, 95% CI = -13.67 to -20.50, P = 0.011, I2 = 87.27%). PRF and PRP demonstrated large effect sizes, while PRGF showed a small effect size.

Conclusion: The use of PRF, PRP, and PRGF showed advantages in treating intrabony defects. However, caution is advised when interpreting the results due to heterogeneity and publication bias among the studies.
