ABSTRACT
Background: Root Coverage Procedures Have Gained Much Popularity In Recent Years. Coronally Advanced Flap (CAF) Is A Predictable Technique For Treating Gingival Recessions. Platelet-rich Fibrin (PRF), An Autologous Platelet Concentrate, Enhances Soft-tissue Wound Healing. Acellular Dermal Matrix Allograft (ADMA) Is A Donated Human Dermis That Was Processed To Remove All Cells And Retain The Regenerative Collagen Matrix. Aim Of The Work: To Compare Between The Effect Of CAF Combined With PRF Membrane And CAF Combined ADMA On Gingival Recession Treatment. Patients And Methods: This Was A Randomized Controlled Clinical Study. Twenty Patients Were Randomly Devided Into Two Groups Which Are PRF Membrane (Group A) And ADMA (group B). The Recorded Parameters Were Probing Depth (PD), Gingival Recession Height (GRH), Clinical Attachment Loss (CAL).

Results: With In Both Groups Significant Differences Were Seen From Baseline To3 Months 6 Months And 9 Months Regarding Reduction In PD, GRH, CAL (P < 0.05).. Intergroup Analysis Showed Statistically Significant Differences Between The 2 Groups In Decrease Of GRH In Favor Of The PRF . Conclusion: Both PFR And ADMA Are Effective Materials In Root Coverage, But PRF Membrane Showed Better And More Stable Results At The End Of 9 Months As Compared To ADMA In Treating Gingival Recession.
