The pouch and tunnel (P and T) and vestibular incision subperiosteal tunnel access (VISTA) techniques are both effective, minimally invasive approaches for root coverage, as both enhance aesthetic outcomes while preserving blood supply and minimizing surgical trauma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim:<\/jats:title>\n                    <jats:p>To evaluate the clinical outcomes of P and T and VISTA, combined with platelet-rich fibrin (PRF) membrane in the treatment of gingival recession defects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>This randomized clinical trial included 12 systemically healthy patients presenting with bilateral isolated gingival recession defects.
