evaluation of the use of L-PRF membrane with coronally repositioned flap in treatment of localized gingival recession (Class I \& II) in comparison with the use of connective tissue graft
Twenty patients, who are candidates for gingival recession coverage, will participate in this prospective clinical trial. Group 1(10 patients) : Coronally repositioned flap will be done and L PRF membrane will be placed into the tissues Group 2 (Control group)(10 patients) : Coronally repositioned flap will be done with sub epithelial connective tissue Parameters * Clinical evaluation of percentage of root coverage and keratinized tissue width * Esthetic outcome evaluation Will be done using the root coverage esthetic score (Cairo et al. 2009) that include Both evaluations will be done at 3, 6 and 9 months

recession treatment
2-Esthetic outcome evaluation was done using Root coverage esthetic score (RES) system ( Cairo et al. 2009) the RES include the following parameters • Level of the gingival margin (GM):(minimum) Zero points = failure of root coverage (gingival margin apical or equal to the baseline recession); 3 points = partial root coverage;(maximum) 6 points = CRC.
Time frame: 9 months
soft tissue thickness (Volumetric assessment)
Preoperatively a cast was made and scanned. At 9 months after surgical procedure the same procedure was done to determine the soft tissue thickness after the surgery. The difference between the tissue thickness before and after was used to determine the efficacy of the different surgical grafting materials used.
Time frame: 9 months
