Surgical procedure was performed by one surgeon. The gingival recession defects were treated by connective tissue graft technique. A connective tissue graft was removed from palate mucosa following Bruno technique. Briefly, a first incision on the palate was performed perpendicularly to the long axis of the teeth, 2 to 3 mm apical to the gingival margin. The mesiodistal length of the incision was determined by the length of the graft required to cover the recession. Since the selected recessions were in maxillary canines and premolars, the length of the graft vary minimally (10-12mm). The second incision was made parallel to the first one, 1-2mm apically, and parallel to the long axis of the teeth in order to separate the subepithelium connective tissue from the epithelial layer. The incision is carried far enough apically to provide a 7mm height of connective tissue to cover the denuded root surface. Afterwards, another incision parallel to the long axis of the teeth, starting from the first incision was performed to separate the subepithelium connective tissue from the periosteum. Then, the connective tissue graft was removed from the palate as atraumatically as possible. Single sutures were made on the palate (4-0 silk) and the graft was sutured on the receptor site
