Twenty-six localized recessions treated with either a lateral sliding flap or a coronally repositioned flap procedure more than 3 years ago were reevaluated. Biometric measurements on the recipient and the donor of control teeth included: a) cementoenamel junction, gingival margin; b) sulcus depth; c) gingival margin, mucogingival line. These recordings were statistically compared to those taken 180 days after the surgical procedures were performed. Pairwise t tests were used to determine whether there were any changes between the 180 days and the 3 years postoperative control with either procedure. A two sample t test was run to see whether the changes obtained with the two procedures differed from each other. No significant changes were found. The values for gingival recession, sulcus depth and width of keratinized gingiva remained stable for both techniques throughout the observation period.

This study was undertaken to evaluate biometrically the changes that occur on the recipient as well as on the donor tooth with regard to gingival recession, sulcus depth and width of keratinized gingiva after performing a lateral sliding flap in the treatment of localized denuded roots. Fourteen teeth with gingival recession were treated using a lateral sliding flap. Measurements were recorded preoperatively and 1, 3 and 6 months after surgery. A mean gain of 2.69 mm of soft tissue coverage over the denuded root was found 6 months postoperatively which represents 69% of coverage. The mean gain in width of keratinized gingiva averaged 3.15 mm. On the donor tooth an average gingival recession of 1.1o mm was found after 6 months, and the width of keratinized gingiva decreased an average of 1.25 mm. Results remained stable after 30 days postsurgery.

Fourteen teeth with localized gingival recessions were treated using a coronally repositioned flap with a free gingival graft (Bernimoulin, 1973). The second step of the procedure was performed 1 month after the free gingival graft was done. Clinical measurements of the recession, sulcus depth and keratinized gingiva were taken preoperatively and at 30, 90 and 180 days after surgery. A mean reduction in the recession of 2.73 mm was obtained after 6 months, which was equivalent to a 64% decrease of the original recession. A significant increase in the width of the keratinized gingiva, averaging 3.27 mm, was found after 6 months. All results remained stable after 30 days postoperatively. The values for gingival recession, sulcus depth and width of keratinized gingiva on the teeth adjacent to the recessions remained unchanged, since they were undisturbed by the procedure.
