This prospective clinical study aims to evaluate and compare the effectiveness of coronally advanced flap (CAF) and tunnel techniques, both combined with platelet-rich fibrin (PRF), in the treatment of multiple Miller Class I-II gingival recessions. Eleven participants with bilateral defects will be treated using a split-mouth design. Periodontal parameters will be assessed at baseline, 3 months, and 6 months.
Age 18 years or older
Systemically healthy individuals
Presence of bilateral Miller Class I-II multiple gingival recessions
Good oral hygiene and willingness to follow instructions
Use of tobacco or smoking
Pregnancy or lactation
Presence of systemic diseases affecting periodontal health
Use of medications that may affect healing (e.g., corticosteroids)
Crossover
CAF with PRF
Procedure/SurgeryCoronally advanced flap technique will be performed to reposition the gingival margin coronally. Platelet-rich fibrin (PRF) membranes will be placed over the exposed root surfaces and stabilized with sutures.
Tunnel with PRF
Procedure/SurgeryA tunnel or subgingival pouch will be created using microsurgical instruments without vertical incisions. Platelet-rich fibrin (PRF) membranes will be inserted into the tunnel and the gingival tissue will be advanced coronally and sutured to cover the recession.
Change in Recession Height (RH)
Recession height will be measured in millimeters from the cementoenamel junction to the gingival margin using a periodontal probe at baseline and 6 months postoperatively.
Change in Clinical Attachment Level (CAL)
Clinical attachment level will be measured in millimeters using a periodontal probe to assess periodontal healing at different time points.
