The goal of this clinical trial is evaluation of the change in depth and width of gingival recession in terms of gingival thickness and esthetics, and evaluation of patient satisfaction in terms of postoperative pain and final esthetic appearance. The study will be conducted on twelve Egyptian healthy patients with localized gingival recession. Researchers will compare clinical effectiveness of collagen membrane to connective tissue graft in treatment of localized gingival recession. The study hypothesis is that no difference exists between Bilayer collagen membrane combined with Pinhole approach and CT graft combined with Pinhole approach used for root coverage in treatment of localized gingival recession.
