Details |
| Intervention |
Pinhole Surgical Technique with Platelet-Rich Fibrin (PRF) membrane |
Participants allocated to the comparator group will undergo management of multiple gingival recession defects using the Pinhole Surgical Technique. A small pinhole access will be created in the alveolar mucosa, through which specialized instruments will be used to gently loosen and advance the gingival tissues coronally. An autologous Platelet-Rich Fibrin (PRF) membrane will be inserted through the pinhole and positioned over the exposed root surfaces. The suturing technique will involve interdental suspensory sutures anchored to presurgically placed composite stops, using 3-0 polypropylene sutures. Standard postoperative care will be provided. 6months follow up. |
| Intervention |
Vestibular Incision Subperiosteal Tunnel Access (VISTA) technique with Platelet-Rich Fibrin (PRF) membrane |
Participants allocated to the intervention group will undergo management of multiple gingival recession defects using the Vestibular Incision Subperiosteal Tunnel Access (VISTA) technique. A single vertical vestibular incision will be placed to allow creation of a subperiosteal tunnel extending beneath the recession defects. Following thorough root surface debridement, an autologous Platelet-Rich Fibrin (PRF) membrane will be placed within the tunnel to cover the exposed root surfaces. The suturing technique will involve 3-0 polypropylene interdental suspensory sutures anchored to presurgically placed composite stops. . Standard postoperative care will be provided.
6months follow up. |

Brief Summary
|
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. |
