Comparative evaluation of vestibular incision subperiosteal tunnel access with platelet-rich fibrin and connective tissue graft in the management of multiple gingival recession defects: A randomized clinical study.

Background: The etiology of gingival recession is often multifactorial. Wide array of surgical techniques are available to manage gingival recession. The aim of the present study was to compare, minimally invasive approach (vestibular incision subperiosteal tunnel access [VISTA]), in combination with platelet-rich fibrin (PRF) and connective tissue graft (CTG) in the management of multiple recession defects in maxillary anterior region.
