Clinical Evaluation of Laterally Closed Tunnel Technique Versus Coronally Advanced Flap Combined With Connective Tissue Graft for the Treatment of Isolated RT2 Gingival Recession

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate reduction of recession depth using lateral closed tunnel technique versus CAF technique using connective tissue graft in single RT2 gingival recession cases.

Official Title
-----------------
Clinical Evaluation of Laterally Closed Tunnel Technique Versus Coronally Advanced Flap Combined With Connective Tissue Graft for the Treatment of Isolated RT2 Gingival Recession: A Randomized Controlled Clinical Trial

Conditions
-----------------
Recession, Gingival

Intervention / Treatment
-----------------
* Procedure: Laterally Closed Tunnel with CTG
* Procedure: CAF with CTG


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Single RT2 buccal gingival recession ≥ 2 mm in the esthetic zone (Gingival recession associated with loss of inter-proximal attachment. The amount of interproximal attachment loss (measured from the interproximal CEJ to the depth of the interproximal pocket) was less than or equal to the buccal attachment loss (measured from the buccal CEJ to the depth of the buccal pocket) Patients with good oral hygiene Medically free patients No signs of active periodontal disease (with no site showing probing depth > 4 mm and full-mouth bleeding score (FMBS) 20% (measured at four sites per tooth). Palate with sufficient thickness to accommodate soft tissue defect. Exclusion Criteria: Smokers Pregnancy Severe gag reflex Non-carious cervical lesion History of mucogingival or periodontal surgery at the experimental site History of medication that can affect periodontal healing

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Laterally closed tunnel technique with CTG<br> | Procedure: Laterally Closed Tunnel with CTG<br>* A novel minimally invasive surgical approach laterally closed tunnel technique (LCT) has been recently introduced for the management of isolated gingival recession. The laterally closed tunnel technique ensures predictability by tunneling and mobilization of flap for graft coverage.<br>|
| Active Comparator: Coronally advanced flap with CTG<br> | Procedure: CAF with CTG<br>* Gold standard surgical technique<br>|
