Healthy Human Volunteers  Gingival Recession.  
 
Intervention / Comparator Agent  
Type  Name  Details 
Comparator Agent  Coronally advanced flap + SCTG+ Emdogain  Participants received coronally advanced flap combined with subepithelial connective tissue graft. Following root surface debridement and conditioning with 24% EDTA for 2 minutes, enamel matrix derivative (Emdogain®) was applied to the root surface. A palatal connective tissue graft was harvested and positioned over the defect, stabilized with sutures. The flap was coronally advanced to completely cover the graft and secured with sling sutures to achieve tension-free primary closure. Palatal site was suture using 3-0 Polypropylene suture (Horizontal criss cross mattress suture) Truseal placed on sutures. Total duration is 1 hour. 
Intervention  Root Coverage with Laterally closed tunnel and Coronally advanced technique with SCTG   Root coverage was performed using a laterally closed tunnel technique combined with coronal advancement in conjunction with subepithelial connective tissue graft and enamel matrix derivative. After tunnel preparation and root conditioning with 24% EDTA, Emdogain was applied to the root surface. A palatal connective tissue graft was harvested and inserted into the tunnel to cover the exposed root. The gingival tissues were approximated laterally and advanced coronally to achieve complete graft coverage, and stabilized with graft with lasso suture and laterally closed with horizontal internal mattress suture and coronally advanced with sling sutures using 5-0 polyglycolic acid sutures. Palatal site was sutured with 3-0 Polypropylene suture. Truseal applied onto sutures. Total Duration of this Procedure is 1hr

Brief Summary  

 This study is a prospective, randomized clinical trial aims to address this research gap by comparing the clinical performance on the gold standard coronally advanced flap and laterally closed tunnel flap associated with connective tissue graft under magnification loupes for the treatment of isolated gingival recession in improving the clinical parameters and patient reported outcomes at 1,3,6 and 12 months follow up .
