Purpose: to measure platelet rich fibrin matrix PRFM in enhancing root coverage of Miller class I and II gingival recession clinically by coronally advanced flap. Materials and Methods: Eighteen healthy patients were randomly splitted for three groups: group I (Test group): five patients treated using Platelet Rich Fibrin Matrix (PRFM) membrane and coronally advanced flap, group II (Positive Control group): fivepatients treated by collagen membrane and coronally advanced flapand group III (Negative control group):five patients treated only using coronally advanced flap. Recession width(RW), recession depth(RD), and probing pocket depth (PPD)were evaluated at baseline,three months and six months respectively. Results: In comparing all groups at all time intervals recorded in RD and RW, a statistically significant difference was found.A great reduction in PPD were recorded at 6 monthsthan at 3 month (P-value = 0.50). However, this different was statistically insignificant. Conclusion: The use of PRFM was effective in treatment of gingival recessions. However, there was no difference recorded between the use of a coronally advanced flap alone and a coronally advanced flap combined with PRFM or collagen membrane in root coverageafter 6 months.
