Palatal Shield Technique for Pain Reduction and Wound Healing After Free Gingival Graft Surgery

5. november 2026 opdateret af: Sameh Samy

Evaluation of Novel Palatal Shield Technique for Improved Donor Site Wound Healing After Free Gingival Graft Surgery: A Randomized Controlled Trial

This randomized controlled clinical trial aims to evaluate the effectiveness of a novel palatal shield technique in reducing postoperative pain and improving wound healing after free gingival graft surgery.

A total of 28 adult participants undergoing palatal tissue harvesting are planned to be enrolled and randomly assigned to two groups.

The experimental group receives a collagen sponge covered by a protective palatal shield made of flowable composite resin, while the control group receives a collagen sponge stabilized with sutures alone.

The primary outcome is postoperative pain, assessed using a 0-10 pain scale. Secondary outcomes include wound size, early wound healing, re-epithelialization, tissue color match, and patient satisfaction.

Postoperative clinical assessments are planned through 30 days after surgery. The study aims to determine whether the palatal shield technique provides better pain control and wound healing compared with conventional collagen sponge dressing.

Intervention / Behandling
Eksperimentel: palatal shield group

Collagen Sponge + Flowable Composite Palatal Shield

A resorbable collagen sponge is placed over the palatal donor site following free gingival graft harvesting and stabilized with sutures. Flowable composite resin is then applied and light-cured to form a protective palatal shield retained by the adjacent teeth.

Collagen Sponge Stabilized With Sutures

Following free gingival graft harvesting, a resorbable collagen sponge is trimmed to fit the palatal donor site and stabilized using sutures without additional composite resin coverage.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
postoperative pain intensity
Tidsramme: Postoperative Days 1, 3, 7, 14, 21, and 30

Postoperative pain intensity will be assessed using a 0-10 Visual Analog Scale (VAS), where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity

Postoperative Days 1, 3, 7, 14, 21, and 30

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
palatal donor site wound size
Tidsramme: Immediately After Surgery and on Postoperative Days 1, 3, 7, 14, 21, and 30

Wound size will be assessed by measuring the length, width, and depth of the palatal donor site using a periodontal probe. Measurements will be recorded in millimeters (mm).

Immediately After Surgery and on Postoperative Days 1, 3, 7, 14, 21, and 30
early palatal wound healing
Tidsramme: Postoperative Days 1, 3, 7, and 14

Early wound healing at the palatal donor site will be assessed by clinical visual inspection using the Early Wound Healing Index (EHI), as described by Wachtel et al. (2003). Healing will be evaluated using a categorical score ranging from 0 to 5, according to the study protocol

Postoperative Days 1, 3, 7, and 14
Palatal Donor Site Re-epithelialization
Tidsramme: Postoperative Days 1, 3, 7, and 14

Re-epithelialization of the palatal donor site will be assessed by clinical visual inspection using a 3-point categorical scale: 1 = No re-epithelialization, 2 = Partial re-epithelialization, and 3 = Complete re-epithelialization. Higher scores indicate more complete epithelial coverage, according to Keceli et al. (2015).

Postoperative Days 1, 3, 7, and 14
palatal donor site color match
Tidsramme: Postoperative Days 1, 3, 7, 14, 21, and 30

Palatal donor site color match will be assessed by visual comparison with the adjacent native palatal mucosa using a 4-point categorical Color Match Rating Scale: 1 = Poor, 2 = Fair, 3 = Good, and 4 = Excellent. The minimum score is 1 and the maximum score is 4. Higher scores indicate better color matching.

Postoperative Days 1, 3, 7, 14, 21, and 30
patient satisfaction
Tidsramme: Postoperative Days 1, 3, 7, 14, 21, and 30

Patient satisfaction will be evaluated using a three-item questionnaire assessing satisfaction with the surgical results, willingness to undergo the procedure again, and willingness to recommend the procedure to others. Responses will be recorded using a 7-point response scale.
