Filter by:Different approaches are used to reduce post-operative complications associated with the palatal wound site after free gingival graft (FGG) harvesting. The aim of this study was to compare the effects of L-PRF and A-PRF on palatal wound healing after free gingival graft harvesting and patients' quality of life.
Palatal-tissue harvesting is a routinely performed procedure in periodontal plastic surgery. Subepithelial connective tissue graft (sCTG) is considered the gold standard in root coverage. However, over the years, several materials have been attempted to accelerate wound healing and to decrease the post-operative patient discomfort and pain, which are considered the most common disadvantages of tissue harvesting from the palate. Reharvesting from the same region could be necessary in some complicated gingical recessions. For this reason, patients may face long treatment times due to recovery periods of the palate between surgeries. Platelet-rich fibrin (PRF) which has 3-dimensional fibrin matrix structure contributes to regeneration of surgical wounds by releasing growth factors for 10-14 days and showing angiogenic properties. In medicine and dentistry, ultrasonography (USG) method can be used to measure tissue thickness, vascularization, elasticity and blood flow. USG, as a non-invasive method, can provide objective data in evaluating the effects of surgical techniques and biomaterials used on soft tissue healing dynamics and tissue perfusion. The investigators hypothesised that leukocyte rich PRF (L-PRF) application to the palatal area after sCTG harvesting could increase palatal tissue thickness and vascularity throughout 3-month follow-up period compared to the controls. Therefore, in this study, the investigators aimed to evaluate the effects of the L-PRF membrane on soft tissue donor site healing after harvesting sCTG in terms of wound healing dynamics using USG method.
The free gingival graft (FGG) procedure is a harvesting technique that creates an open wound that heals by secondary intention. Retarded wound healing, excessive bleeding, and postoperative pain have been reported after FGG procedures. Hemostatic agents include ferric sub-sulfate solution, absorbable synthetic collagen, absorbable gelatin sponge, or oxidized regenerated cellulose. The agents are often combined with a surgical stent designed to cover the donor site, providing protection and pressure hemostasis. Diode laser also exhibits excellent thermal effects with deep tissue penetrative properties, to enhance coagulation. Laser Bandage (LB) could also enhance wound healing and reduce subjective postoperative complications in the palatal donor area after harvesting FGG similarly.
The purpose of this study is to compare four different connective tissue graft harvesting technique in terms of graft quality and patient post-operative morbidity
Postoperative complications associated with free gingival graft (FGG) procedures are prolonged bleeding from the donor site, postoperative pain and delayed wound healing which increases the patients' morbidity. Hence, the aim of this study is to assess the effectiveness of different treatment modalities on palatal wound healing and patient's morbidity after FGG. Ninety patients requiring FGG were randomly will be assigned into six groups: group 1: Platelet rich fibrin (PRF) membrane, group 2: Essix retainer, group 3: topical ozone therapy, group 4: low-level laser therapy (LLLT), group 5: collagen fleece and group 6: untreated control group. Epithelization will be evaluated by means of bubble formation; sensitivity, edema, pain, changes in eating habits and burning sensation will be assessed by using visual analog scale (VAS) and also the presence of discomfort and bleeding will be evaluated in the postoperative first week and at 14 days, 1 and 3 months postoperatively.
