Brief summary

Detailed description

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).

Design outcomes

Primary

Measure	Time frame	Description
Gingival margin	6 month after surgery	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.
Marginal tissue contour	6 month after surgery	Score 0: irregular gingival margin (it does not follow CEJ); Score 1: proper marginal contour/scalloped gingival margin (following CEJ).
Soft tissue texture	6 month after surgery	Score 0: presence of scar formation and/or keloid-like appearance; Score 1: absence of scar or keloid formation.
Mucogingival junction	6 month after surgery	Score 0: MGJ not aligned with MGJ on adjacent teeth; Score 1: MGJ aligned with MGJ on adjacent teeth.
Gingival color	6 month after surgery	Score 0: color of tissue differs from gingival color on adjacent teeth; Score 1: normal color and integration with the adjacent soft tissues.
