Cyanoacrylate glue versus collagen sponge for healing palatal donor wounds

Effect of Cyanoacrylate Tissue Adhesive Versus Collagen Sponge on Palatal Donor Site Healing After Harvesting a Free Gingival Graft: a Randomized Controlled Clinical Trial

Early Phase 1 Interventional Beirut Arab University · NCT07086482

This test compares cyanoacrylate glue (PeriAcryl) and collagen sponge to see which helps adult patients' palatal donor sites heal faster and feel more comfortable after a free gingival graft.

What this trial studies

This single-center interventional Early Phase 1 trial at Beirut Arab University compares cyanoacrylate tissue adhesive (PeriAcryl) to a collagen sponge for managing palatal donor wounds after free gingival graft harvesting. Eligible healthy adult patients are assigned to either PeriAcryl applied over the wound or a collagen sponge stabilized with sutures, then followed at scheduled visits to monitor healing and complications. Primary outcomes are wound healing and re-epithelialization, while secondary outcomes include patient satisfaction and oral-health–related quality of life. Clinical exams and patient-reported measures will document healing speed, postoperative symptoms, and any adverse events.

Who should consider this trial

Good fit: Adults in good general health (ASA I-II) who need a free gingival graft, have healthy gingiva with low plaque and bleeding scores, and can attend follow-up visits are ideal candidates.

Not a fit: Patients with systemic diseases, coagulation disorders, heavy smokers (>10 cigarettes/day), pregnant or lactating individuals, or those with relevant drug/allergy issues are unlikely to benefit and are excluded.

Why it matters

Potential benefit: If successful, PeriAcryl could speed palatal wound healing, reduce postoperative pain and complications, and improve patient comfort after graft harvesting.

How similar studies have performed: Cyanoacrylate adhesives have been used successfully for oral soft-tissue closure in prior reports, but randomized comparisons specifically against collagen sponge for palatal donor sites are limited.
