Vestibular Incision Subperiosteal Tunnel Access (VISTA) Technique vs Pinhole Surgical Technique (PST) in the Management of Multiple Gingival Recession Defects: A Randomized Clinical Trial

Gingival recession is a common periodontal condition that can affect esthetics, root sensitivity, and oral health–related quality of life. Minimally invasive surgical techniques have been introduced to manage multiple gingival recession defects with reduced patient morbidity. The present randomized clinical trial aims to compare the clinical effectiveness of Vestibular Incision Subperiosteal Tunnel Access (VISTA) and Pinhole Surgical Technique in the management of multiple gingival recession defects using Platelet-Rich Fibrin (PRF) membrane.

Systemically healthy patients presenting with multiple gingival recession defects will be randomly allocated into two groups. Group I will be treated using the VISTA technique with PRF membrane, while Group II will undergo the Pinhole Surgical Technique with PRF membrane. Clinical parameters including recession depth, recession width, clinical attachment level, width of keratinized gingiva, gingival thickness, and patient-reported outcomes will be assessed at baseline and at follow-up intervals. The study aims to evaluate & compare the clinical effectiveness of VISTA technique and PST in achieving predictable root coverage.
