Aims. The primary aim of this randomized, blinded, controlled clinical trial was to compare the percent root coverage obtained using a coronally positioned tunnel surgery plus an acellular dermal matrix allograft (ADM) with single tooth sling versus continuous sling sutures 6 months post-surgically. Methods. Twenty-four patients with 1 site of ~3 mm Miller Class I or II recession were treated and followed for 6 months. Twelve patients received a coronally positioned tunnel plus ADM and single tooth sling sutures (Single) and were considered the test group. The positive control group consisted of 12 patients treated with a coronally positioned tunnel technique plus ADM with continuous sling sutures (Continuous). Patients were randomly selected by a coin toss to receive either the test or control treatment. Results. The mean facial recession defect at the initial exam for the Single group was 3.4 ± 0.6 mm which was reduced to 0.8 ± 0.8 mm at the 6 month exam for a gain of 2.5 ± 0.7 mm or 76% defect coverage (p < 0.05). The mean facial recession defect at the initial exam for the Continuous group was 3.0 ± 0.0 mm which was reduced to 0.5 ± 0.8 mm at the 6 month exam for a gain of 2.5 ± 0.8 mm or 83% defect coverage (p < 0.05). There were no statistically significant differences between groups (p > 0.05). Probing depth increased 0.1 mm for the Single group and 0.2 mm for the Continuous group (p < 0.05) from baseline to 6 months. Clinical attachment level increased 2.4 mm for the Single group (p < 0.05) and 2.3 mm for the Continuous group (p < 0.05) at the 6-month final measurement. Mean keratinized tissue increased in the Single group by 0.3 mm and 0.0 mm in the Control group (p > 0.05). There were no statistically significant differences between groups (p > 0.05). There was no gain of creeping attachment for either the Single or Continuous group. Conclusions. The coronally positioned tunnel plus ADM and single tooth sling produced 76% defect coverage while the coronally positioned tunnel plus ADM and continuous sling produced 83 % defect coverage. This difference was considered clinically significant but was not statistically significant.
