 Clinical measurements were taken at starting point and 6 months postoperatively. The measurements comprised an assessment of probing depth PD,clinical attachment level CAL and gingival recession parameters including recession depth RD, recession width RW, keratinized tissue width KTW and gingival thickness GT were assessed by a calibrated examiner E. Ö.. PD, CAL, RD, RW and KTW values were recorded by a Williams probe graduated in 1-mm increments and rounded up to the nearest millimeter Hu Friedy, Chicago, IL, USA. To standardize the clinical measurements acrylic stents were prepared on patients casts. The following measurements were recorded at the mid-buccal point of the teeth at baseline and6 months after surgery. GT was evaluated using endodontic reamer attached to a rubber stopper inserted perpendicularly into the gingival tissue 3 mm below the gingival margin under local anesthesia, and then the thickness was measured to the nearest 0.1 mm using a caliper.RD was measured from the CEJ to the gingival margin, RW was measured tangentially at the mid-facial CEJ and RA was calculated as the area within the contour of denuded root. KTW recorded as the distance from the mucogingival junction to the gingival margin. Duplicate measurements were made for RD, RW, RA and KTW with an interval of 24 hours and the average value of two measurements was used for the assessment. The postoperative pain was evaluated with a visual analog score VAS.
