Study Overview
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.

Inclusion Criteria
- •Patients 18 years or older.
- •Patients with healthy systemic condition
- •Buccal recession defects with recession type 2 defects.
- •Clinical indication and/or patient request for recession coverage.
- •O'Leary index less than 20%

Arms & Interventions
Group A : Lateral closed Tunnel
Laterally closed tunnel procedure with subepithelial connective tissue graft (sCTG) After local anesthesia, root planing will be performed. Recession defect - a tunneling technique will be prepared using sulcular incision is made through the gingival margin and extends post the mucogingival line leaving the interdental papilla intact.
• Recipient site; Using either single or mattress sutures, the graft 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. 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.
Intervention: Group A (Lateral closed tunnel subepithelial CT graft) (Procedure)
Group B : Tunneling
Tunnel procedure with subepithelial connective tissue graft (sCTG) - Control:
At the recipient site (recession defect): a tunneling technique will be prepared using sulcular incision is made through the gingival margin and extends post the mucogingival line leaving the interdental papilla intact.
Then the graft is placed and secured in the recipient site. The flap is displaced to be in a coronal position using a sling suture with no suturing to approximate the margins together.
Intervention: Group B (Tunnel procedure with subepithelial CT graft) (Procedure)
