Abstract
BackgroundA coronally advanced flap with subepithelial connective tissue graft is the gold standard surgical treatment of gingival recessions, since it offers a higher probability of achieving complete root coverage compared with other techniques. However, optimum short- and middle-term clinical results have also been obtained with coronally advanced flaps alone. The aim of the present study was to evaluate the results obtained by the surgical treatment of localized gingival recessions using coronally advanced flaps with or without subepithelial connective tissue graft.Material and MethodsThe reduction of recession height was assessed, together with the gain in gingival attachment apical to the recession, and total reduction of recession, in a comparative study of two techniques. Twenty-two gingival recessions were operated upon: 13 in the control group (coronally advanced flap) and 9 in the test group (coronally advanced flap associated to subepithelial connective tissue graft).ResultsAfter 18 months, the mean reduction of recession height was 2.2 ± 0.8 mm in the control group and 2.3 ± 0.7 mm in the test group, with a mean gain in gingival attachment of 1.3 ± 0.9 mm and 2.3 ± 1.3 mm, respectively. In percentage terms, the mean reduction of recession height was 84.6 ± 19.6% in the control group and 81.7 ± 17.8% in the test group, with a mean gain in gingival attachment of 20.5 ± 37.4% and 184.4 ± 135.5%, respectively.ConclusionsSignificant reduction of gingival recession was achieved with both techniques, though the mean gain in gingival attachment (in mm and as a %) was greater in test group. Key words:Gingival recession, coronally advanced flap, subepthelial connective tissue graft.

70 were discarded for the following reasons: coronally advanced flap procedures involving two or more adjacent recessions (22 patients); less than 18 months of follow-up (12 patients); evaluation or re-evaluation not made by the same examiner (10 patients); patients subjected to non-autologous subepie223
In order to isolate the possible effect of the surgical technique from other confounding factors, we evaluated the homogeneity of the groups (CG and test group (TG)) in relation to age, gender, smoking habit, periodontal disease, biotype and Miller recession class
