Effects of Epithelialization-enhancing Agents Following Diode Laser-assisted Frenectomy: A Randomized Clinical Trial
2026年8月14日 更新者：Roko Bjelica、University of Zagreb
The purpose of this randomized clinical trial is to evaluate and compare the effects of two topical epithelialization-enhancing agents-a hyaluronic acid-based gel (Gengigel®) and a bioactive micronutrient-based gel (Miradont®-Gel)-versus no topical agent (control) on soft tissue wound healing following diode laser-assisted maxillary labial frenectomy.
Pediatric and adolescent patients requiring maxillary labial frenectomy are randomly assigned into three parallel groups:Control Group: Diode laser frenectomy without topical agent application.
Miradont® Group: Diode laser frenectomy followed by postoperative application of Miradont®-Gel three times daily for 14 days.
Gengigel® Group: Diode laser frenectomy followed by postoperative application of Gengigel® three times daily for 14 days.
Postoperative wound healing, re-epithelialization, and cellular maturation are evaluated clinically and cytologically on days 3, 7, and 14 following the surgical intervention.

详细说明
Diode lasers are widely utilized in soft tissue oral surgery due to their precise cutting, intraoperative decontamination, and minimal bleeding; however, thermal damage can sometimes lead to delayed secondary-intention epithelialization.
This randomized clinical study investigates whether adjunctive topical application of hyaluronic acid gel or micronutrient gel accelerates mucosal regeneration and reduces inflammatory response following high-power diode laser frenectomy (975 nm, 4W).
Clinical parameters (hyperemia, edema, bleeding, fibrinous adhesion) and semi-quantitative cytological markers (granulocytes, erythrocytes, epithelial cells, stromal cells, and Maturation Index) are longitudinally analyzed at Days 3, 7, and 14 post-intervention.

参与者组/臂 |
干预/治疗 |
|---|---|
|
无干预：Control group
Patients undergo diode laser-assisted maxillary labial frenectomy without the postoperative application of any topical epithelialization-enhancing agent.
|
|
|
实验性的：Miradont-Gel Group
Patients undergo diode laser-assisted maxillary labial frenectomy followed by topical application of Miradont®-Gel (approx.
0.5 ml) to the surgical site three times daily for 14 days.
|
opical application of bioactive micronutrient gel containing vitamins and minerals (approx.
0.5 ml) directly to the laser surgical wound three times daily (after meals and before sleep) for 14 consecutive days.

实验性的：Gengigel Group
Patients undergo diode laser-assisted maxillary labial frenectomy followed by topical application of Gengigel® (hyaluronic acid gel, approx.
0.5 ml) to the surgical site three times daily for 14 days.
|
Topical application of hyaluronic acid gel (approx.
0.5 ml) directly to the laser surgical wound three times daily (after meals and before sleep) for 14 consecutive days.

主要结果指标

措施说明 |
大体时间 |
|---|---|---|
|
Epithelial Maturation Index (MI)
大体时间：Day 3, Day 7, and Day 14 post-intervention
|
Quantitative assessment of mucosal epithelial differentiation and cellular maturation evaluated by cytological smears from the surgical wound using the standardized Frost method.
The index calculates the percentage distribution of basal, parabasal, intermediate, and superficial epithelial cells to determine the degree of tissue regeneration.

Inflammatory Response (Granulocyte Presence Score)
大体时间：Day 3, Day 7, and Day 14 post-intervention
|
Semi-quantitative cytological assessment of inflammatory infiltrate in wound smears, scored on a 4-point scale: 0 = absence of granulocytes / clean background; 1 = low presence (≤ 2); 2 = moderate presence (2 < n ≤ 5); 3 = significant presence with tissue detritus (> 5).
Lower scores indicate faster resolution of inflammation.
|
Day 3, Day 7, and Day 14 post-intervention
|
|
Re-Epithelialization
大体时间：Day 3, Day 7, and Day 14 post-intervention
|
Semi-quantitative cytological score evaluating the density of epithelial cells in wound smears on a 4-point scale: 0 = absence/minimal presence; 1 = low presence (≤ 2); 2 = moderate presence (2 < n ≤ 5); 3 = satisfactory presence (> 5).
Higher scores indicate advanced re-epithelialization.
|
Day 3, Day 7, and Day 14 post-intervention

Clinical Wound Healing and Complications
大体时间：Day 3, Day 7, and Day 14 post-intervention
|
Clinical evaluation of secondary-intention wound healing at the surgical site, recording the presence or absence of postoperative hyperemia, edema, postoperative bleeding, and fibrinous deposition.
|
Day 3, Day 7, and Day 14 post-intervention
|
|
Preoperative Patient Fear Score
大体时间：Immediately prior to surgical intervention
|
Patient-reported subjective fear and anxiety assessed prior to the procedure using a Visual Analogue Scale (VAS) ranging from 0 (no fear) to 10 (extreme fear), categorized into low (0-3), moderate (4-6), and strong fear (7-10).
