Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates postoperative morbidity of patients that undergo free gingival graft harvesting from palate with or without use of autogenous PRF (Platelet Rich Fibrin) membranes to cover the donor site.In the Test Group venous blood sampling was done in order to prepare PRF membranes used to cover the donor site, whereas in Control Group hemostatic agents with oxidized and regenerated cellulosa were used.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Test Group

In the Test Group venous blood sampling was done in order to prepare PRF membranes used to cover the donor site of the connective tissue graft.

Group Type EXPERIMENTAL

Platelet rich fibrin ( PRF)

Intervention Type BIOLOGICAL

Venous blood was collected with a butterfly needle in two 10 mL tubes without anticoagulants or other chemicals. The tubes were immediately centrifuged at 3000 rpm for 10 minutes.

At the end of centrifugation a fibrin clot (PRF) was obtained in the middle of the tube, just between the red corpuscles at the bottom and acellular plasma at the top. The PRF clot was taken from the tube and the red cells portion at the base of the clot was eliminated with sterile scissors Then the PRF was enveloped in sterile gauzes and positioned between two glass plates: the compression drove out the serum from the clot obtaining PRF membranes that were ready to be used in the surgical site.

Control Group

In Control Group hemostatic agents with oxidized and regenerated cellulosa were used to cover the donor site.

Group Type ACTIVE_COMPARATOR

hemostatic agents with oxidized and regenerated cellulosa

Intervention Type DRUG

In the Control Group hemostatic agents with oxidized and regenerated cellulosa were sutured to the palatal wound with mattress suture ( silk 5/0).
