Summary

The goal of this clinical trial is to learn if the use of cyanoacrylate glue (PeriAcryl) is effective in healing of the palatal donor site in adults requiring a free gingival graft. The main question\[s\] it aims to answer \[is/are\]: Does PeriAcryl accelerate the palatal tissue healing compared with the use of collagen sponge? Does PeriAcryl usage leave the patients more satisfied? Researcher will compare the outcomes of participants treated with PeriAcryl to those treated with collagen sponge to see if PeriAcryl accelerated the healing process of palatal tissues and led to fewer postoperative complications. Participants will: * be assigned to a study group using PeriAcryl or control group using Collagen sponge. * be followed-up to monitor healing and gather clinical information.

Detailed description

This study investigates new approaches to make management of the palatal donor area easier to the operator and more comfortable to the patient. More specifically, it compares the use of PeriAcryl glue (PA) to the use of collagen sponge after harvesting a free gingival graft from the palate in terms of wound healing and epithelization primarily, and patients satisfaction and oral health related quality of life secondarily. Participants selection: Healthy patients (with no systemic diseases or coagulation disorders) requiring a free gingival graft to treat a gingival recession or keratinized tissue deficiency around implants and natural teeth will be recruited. Participants included in this study must have clinically healthy gingiva and good oral hygiene. Participants grouping: * Control group: Hemostasis will be achieved by collagen sponge stabilized with 4/0 silk (x) suture on the palatal wound. * Test group: Cyanoacrylate tissue adhesive (Periacryl®, GluStitch Inc., Canada) will be applied with a pipette following manufacturer's instructions on the entire area of the wound. All the procedures will be achieved with the full knowledge and consent of the patient. A written informed consent will be obtained for each patient included in this study. Surgical Protocol: * Full mouth scaling will be done for every patient at least 2 weeks before the surgery. * The donor area will be anesthetized using articaine 4% with epinephrine 1:100,000. * Palatal tissue thickness will be measured using a periodontal probe. Then a free gingival graft (FGG) will be harvested using a 15c blade of 1 to 1.5 mm in thickness, approximately 3 mm away from the palatal gingival margin. * Pressure will be applied to the donor surface using gauze soaked in saline solution to stop bleeding, while the FGG will be prepared, stabilized and sutured at the recipient site. * The operator will then receive a sealed envelope holding each patient's assigned grouping as soon as the graft extraction process is finished. Post-operative Care: All patients will get the same prescription of antibiotics (Amoxiclave 1g) twice daily for 7 days, and Ibuprofen 600 mg every 8 hours only taken when needed. As well as chlorohexidine 0.12% mouthwash twice daily for 2 weeks. The same instructions will be given to all the patients (cease smoking, soft diet, oral hygiene, not brushing hard and causing trauma to the surgical site...). The test group participants receiving PA in the palatal donor will be informed about the material and that it will disintegrate on its own after 10 days. While the control group participants receiving collagen sponge with (x) sutures in the palatal donor will be informed that the sutures will be removed after 2 weeks. Following the operation, a questionnaire will be given to each patient asking them to record any spontaneous bleeding of the surgical incision during the first seven days following the procedure, as well as to rate their level of postoperative discomfort using a visual analogue scale (VAS), quantity of analgesics taken, and other questions related to quality of life. Follow-ups: All patients will be followed-up at 7, 14, 21 days, 1 month, 2 months, and 3 months, to evaluate healing up to the formation of the first epithelial layer as evaluated by pressure with a periodontal probe and Laundry wound healing index, and the time of complete integrity of the treated palatal fibromucosa.

Type	Name	Description
COMBINATION_PRODUCT	Cyanoacrylate tissue adhesive	Cyanoacrylate tissue adhesive is a chemical synthetic and hybrid tissue sealant possessing strong, rapid acting adhesive properties and is often used in general surgery. Recently, cyanoacrylate tissue adhesive has been effectively introduced into dentistry to close wounds and stop ischemic areas from forming in periodontal aesthetic surgeries. As well as in exposed membranes to preserve the bone graft after guided bone regeneration, in post-extraction sockets, and to seal any surgical flap. This material has strong hemostatic, bacteriostatic, and sealing qualities.
DEVICE	Collagen sponge	Collagen sponge is an organic polymer that promotes the development of blood clots, and it resorbs quickly and completely over time. Collagen sponge create a matrix at the bleeding site, encourage platelet activation and aggregation, and engage the extrinsic coagulation pathway. Thus, it can be utilized as the first choice for wound healing.
