Brief summary
This study aims to assess the effect of tunneling technique with subepithelial connective tissue graft versus tunneling technique with laterally closed tunnel in treatment of recession type 2 defect.Few randomized clinical trial has been involved with recession type 2 defects treated with tunneling technique and coronal advanced flap.
Detailed description
Tunneling with subepithelial connective tissue graft: At the recipient site (recession defect): After scaling and root planning. A sulcular incision is made through the gingival margin and extends post the mucogingival line leaving the interdental papilla intact. At donor site (palate): A connective tissue graft is harvested from the palate after administration of local anesthesia using a partial thickness flap which will be raised with single incision. Then the graft is placed and secured in the recipient site using suture. The flap is displaced to be in a coronal position using a suture. Tunneling technique with the laterally closed tunnel): After local anesthesia, root planing of the exposed root surface will be performed. An intrasulcular incisions will be made creating a tunnel extending to the mucogingival line and mesial and distal recession defects while keeping the interdental papilla intact as well as not perforating the flap. * Donor SCTG Subsequently, a palatal SCTG will be harvested by means of the single incision technique with immediate closure of the donor site. * Recipient site; Using either single or mattress sutures, the SCTG will be pulled and fixed mesially and distally at the inner aspect of the pouch. The graft will be adapted to the CEJ by means of a sling suture. Finally, the margins of the pouch will be pulled together over the graft and sutured with interrupted sutures to accomplish tension-free complete or partial coverage of the graft as well as the denuded root surface.
Interventions
PROCEDUREGroup A (Lateral closed tunnel subepithelial CT graft)
Subepithelial connective tissue graft (autogenous graft) will be harvested from the palate by Single incision technique to be used with the adjacent teeth to treating gingival recession with edges of the recession sutured together after placing connective tissue graft
PROCEDUREGroup B (Tunnel procedure with subepithelial CT graft)
Subepithelial connective tissue graft (autogenous graft) will be harvested from the palate by Single incision technique to be used with the prepared tunnel to treating gingival recession

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Reduction Recession Depth | 6 month | recession depth measured from CEJ to the gingival margin in a cross-section at the central buccal site. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gingival recession width | 6 month | Measured as the distance between the gingival margin adjacent to the defect |
| Root coverage esthetic score (RES) | 6 month | system used to evaluated five variables 6 months gingival margin (GM), marginal tissue contour (MTC), soft tissue texture (STT), MGJ alignment, and gingival color (GC). |
| Probing depth | 6 month | Measured from the gingival margin to the bottom of the gingival sulcus |
| Clinical attachment level | 6 month | Measured from the CEJ to the bottom of the gingival sulcus. |
| Gingival recession depth. | 6 month | Measured as the distance between the gingival margin and the mucogingival junction |
| Gingival thickness | 6 month | The measurement of Gingival tissue thickness is performed 2 mm apical from the gingival margin. |
| Post-operative pain | 2 weeks | Visual Analogue Scale (VAS) with numbers from 0 to 10 ('no pain' to 'worst' pain imaginable) |
| Post-Surgical Patient Satisfaction Questionnaire | 6 month | A 3-item questionnaire is asked and the patients shall use a 7-point answer scale. The answers were given on a 7-point scale ranging from 1 ''not at all'' to 7 ''very likely'' |
| Percentage complete root coverage | 6 month | (Preoperative vertical recession -- Postoperative vertical recession/preoperative vertical recession) x 100 |
| Width of keratinized tissue | 6 month | Measured as the distance between the gingival margin and the mucogingival junction |
