Background: The aim of this randomized clinical trial (RCT) was to evaluate the adjunctive benefit of Connective Tissue Graft (CTG) to Coronally Advanced Flap (CAF) for the treatment of gingival recession associated with inter-dental clinical attachment loss equal or smaller to the buccal attachment loss (RT2). Material and Methods:The patients were randomly assigned to CAF+CTG (test group) or to CAF alone (Control group). Measurements were performed by a blind and calibrated examiner. Outcome measures included complete root coverage (CRC), recession reduction (RecRed), Root coverage Esthetic Score (RES), intra-operative and post-operative morbidity, and root sensitivity.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CAF+CTG | Experimental | After local anaesthesia, a split-full-split thickness flap was elevated. The papillae adjacent to the involved tooth were then de-epithelialized. A gentle root debridement was performed. A 1-2-mm-thick CTG was harvested using a single incision approach from the palate in the area between the second pre-molar and the second molar. The wound on the donor site of the palate was then sutured. The graft was positioned on the instrumented root surface immediately apical or at the level of the CEJ and then stabilized using a compressive crossing suture, anchored to the periosteum apical to the graft and closed with a palatal knot. The flap was coronally displaced 1-2 mm above the CEJ and sutured |
