Treatment of Buccal Ginvigal Recessions With the Tunnel Technique in Conjunction With Cross-linked Hyaluronic Acid and Subepithelial Connective Tissue Graft. A Randomized Clinical Trial

University of Lisbon30 enrolled

Overview

To evaluate the outcomes of buccal gengival recession type 1 (RT1) treated with the tunnel technique in conjunction with a cross-linked hyaluronic acid and subepithelial palatal connective tissue grafts. To evaluate the esthetic outcome as perceived by periodontists, using the root coverage esthetic score (RES). Test Group - Tunnel technique in conjunction with a cross-linked hyaluronic acid and subepithelial palatal connective tissue grafts. Control Group - Tunnel technique and subepithelial palatal connective tissue grafts.

Inclusion Criteria: * None of the patients were smokers and all were systemically healthy without any signs of periodontal disease. * Each patient had to display at least one ginvigal recession (RT1) of a depth of ≥ 2 mm. * Patients exhibited an adequate level of oral hygiene evidenced by a full- mouth plaque score (FMPS) \< 25%39 and full-mouth bleeding score (FMBS) \< 25%. Exclusion Criteria: * Smokers * Gingival recesstion RT 2 or RT 3 (Cairo 2011).

Outcomes

Primary Outcomes

Gingival margin

Score 0: failure of root coverage (gingival margin apical or equal to the baseline recession); Score 3: partial root coverage; Score 6: complete root coverage with no detectable CEJ.
