详细描述
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.

入选标准
- •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%.
排除标准
- •Gingival recesstion RT 2 or RT 3 (Cairo 2011).
结局指标
主要结局
Marginal tissue contour
时间窗: 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
时间窗: 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
时间窗: 6 month after surgery
Score 0: MGJ not aligned with MGJ on adjacent teeth; Score 1: MGJ aligned with MGJ on adjacent teeth.
Gingival margin
时间窗: 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.
Gingival color
时间窗: 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.
