Clinical Evaluation of (TCAF) Versus (CAF) Combined With Connective Tissue Graft in the Treatment of Multiple RT2 Gingival Recession Sites

Several techniques for gingival recession defects have been developed for treatment such as are pedicle soft-tissue graft (rotational flap procedures, advanced flap procedure and tunneling), free soft-tissue graft (epithelialized and subepithelial connective tissue graft) and regenerative procedures (barrier membrane or biologic mediators.

The coronally advanced flap and the tunneling technique are the most commonly performed surgical approaches for treating gingival recessions. Barootchi et al. 2024 conducted a clinical study using tunnel coronal advanced flap technique(TCAF) for treating multiple RT2 gingival recession defects ,in order to combine the advantage of both better access and graft stabilization in CAF and the preservation of the integrity of the papilla and better blood supply to the graft present in tunneling technique. From the previous study it was concluded that the combination of both techniques in the same surgical design can improve both the flap and graft vascularization and enhance clinical, esthetic, and patient-reported outcomes. To our knowledge, there is no conducted randomized clinical trials comparing the tunneled coronally advanced flap technique to the coronally advanced flap for gingival depth reduction in multiple RT2 recessions.

So, this clinical trial aims to address this gap of the literature.
