Palatal Wound Healing After Free Gingival Graft Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

kollajen membran (Cytoplast™ RTMFOAM™, Osteogenics Biomedical Inc., Texas, ABD): A kollajen membran (Cytoplast™ RTMFOAM™, Osteogenics Biomedical Inc., Texas, ABD) will be applied to the palatal donor site following free gingival graft harvesting to control bleeding and support wound healing. The donor area will be covered with sterile aluminum foil and a periodontal dressing.

triamcinolone acetonide: Topical triamcinolone acetonide will be applied to the palatal donor site following free gingival graft harvesting to reduce postoperative inflammation and improve wound healing. The donor area will be covered with sterile aluminum foil and a periodontal dressing.

Study summary

This randomized controlled clinical trial aims to evaluate the effects of topical triamcinolone acetonide application on wound healing and patient-reported outcomes at the palatal donor site following free gingival graft (FGG) surgery. A total of 55 patients with mucogingival deficiencies requiring FGG will be randomly assigned to either a control group receiving a collagen membrane or a test group receiving topical triamcinolone acetonide at the donor site. All palatal donor areas will be protected with a periodontal dressing. Clinical assessments will be performed on postoperative days 3, 7, 14, and 30. Wound epithelialization will be evaluated using the hydrogen peroxide bubbling test, while wound healing and scar formation will be assessed using the Landry, Turnbull, and Howley index and the modified Manchester Scar Scale, respectively. Patient-centered outcomes, including postoperative pain, discomfort, analgesic consumption, and oral health-related quality of life, will be assessed using visual analog scales and the Oral Health Impact Profile-14 questionnaire. The findings of this study are expected to provide evidence regarding the potential benefits of topical corticosteroid use in reducing palatal donor site morbidity following FGG surgery.

Eligibility

Primary outcome measure(s)

• Oral Health-Related Quality of Life — Postoperative Days 3, 7, 14, and 30
  Oral health-related quality of life was evaluated using the Oral Health Impact Profile-14 questionnaire. The scale consists of 14 items scored on a 5-point Likert scale ranging from 0 (never) to 4 (very often). Total scores range from 0 to 56, with higher scores indicating poorer oral health-related quality of life.
• Number of participants with complete wound epithelialization — Postoperative Days 3, 7, 14, and 30
  Epithelialization of the palatal donor site will be evaluated using the hydrogen peroxide (H₂O₂) bubbling test. The presence of bubbling will be recorded as absence of epithelialization, whereas the absence of bubbling will indicate complete epithelialization.
• Wound Healing at the Palatal Donor Site — Postoperative Days 3, 7, 14, and 30
  Soft tissue healing was assessed using the Landry, Turnbull, and Howley Healing Index . The index is scored on a 5-point scale ranging from 1 to 5, where higher scores indicate better wound healing.
• Scar Formation — Postoperative Days 3, 7, 14, and 30
  Scar formation at the palatal donor site, including color match, contour, and tissue deformity, will be evaluated using the Modified Manchester Scar Scale, which is scored on a scale ranging from 0 to 4, where higher scores indicate poorer scar outcomes.
