NCT06370260

Brief Summary

This study aims to assess the effectiveness and safety of a hydrogen carbamide/peroxide gel, called UNISEPT® ORAL GEL, in promoting oral wound healing, alleviating postoperative symptoms, and enhancing oral hygiene. Study participants will include individuals with any suspicious lesion in their gums or the roof of their mouth. They will undergo a procedure to remove a small piece of tissue for testing (biopsy) in order to confirm the diagnosis.This is a standardized diagnostic procedure that involves the use of a punch, which is a plastic handpiece with a cylindrical cutting blade. Subsequently, the wound heals naturally without the need for sutures. Researchers are comparing this gel with a placebo (a look-and-taste-alike substance that contains no active ingredients) to see if it is helpful with healing of wounds in the mouth and associated symptoms, improving oral hygiene. Participants randomly get the hydrogen carbamide/peroxide gel or the placebo one to use for 14 days after the biopsy. The researchers will not know which one they are providing as the gel tubes will be identical. Oral wound healing, postoperative symptoms (such as pain, eating and speech difficulties), oral hygiene (dental plaque and gingival inflammation) and quality of life are assessed during a 14-day period after the biopsy. Participants are required to visit the clinic three times, one for the initial biopsy, one at 7 days and one at 14 days after the biopsy. They are asked to fill in some questionnaires, while certain procedures (taking a photo the site of the biopsy) and assessments (like evaluating the dental plaque and gingival inflammation) take place. During the first week they, also, keep a diary of their symptoms, as instructed.

Outcome Measures

Primary Outcomes (2)

  • Assessment of wound healing based on Percentage Healing Index on day 14

    The Percentage Healing Index (PHI) is calculated based on three distinct values: the wound area at T0 and T2.These values are acquired through standardized pictures taken immediately after biopsy (T0) and 14 days post-biopsy (T2), with the aid of a UNC 15 (North Carolina) periodontal probe, acting as a calibrator, that was placed alongside the treated area.The images obtained are processed using software (Image J, developed by Wayne Rasband and contributors at the National Institutes of Health, USA), capable of calculating the area in square millimeters (mm). Initially, the T2 area is divided by the T0 area, and the result is multiplied by 100. The resulting value, known as the percentage unhealed index (PUI), indicates the percentage of the lesion that remained unhealed. The complementary value to this percentage is defined as the PHI at T2. Comparisons will be made between the UNISEPT® ORAL GEL versus the placebo group.

    Day 14

  • Assessment of wound healing based on Percentage Healing Index on day 7

    The Percentage Healing Index (PHI) is calculated based on three distinct values: the wound area at T0 and T1.These values are acquired through digital photographs taken immediately after biopsy (T0) and at 7 days post-biopsy (T1), with the aid of a periodontal probe, acting as a calibrator, that was placed alongside the treated area.The images obtained are processed using software (Image J, developed by Wayne Rasband and contributors at the National Institutes of Health, USA), capable of calculating the area in square millimeters. Initially, the T1 area is divided by the T0 area, and the result is multiplied by 100.The resulting value, known as the percentage unhealed index (PUI), indicates the percentage of the lesion that remained unhealed. The complementary value to this percentage is defined as the PHI at T1. Comparisons will be made between the UNISEPT® ORAL GEL versus the placebo group.

Study Arms (2)

UNISEPT® ORAL GEL

EXPERIMENTAL

A gel containing hydrogen carbamide/peroxide as active ingredient

Device: Hydrogen Carbamide/Peroxide Gel

PLACEBO

PLACEBO COMPARATOR

A gel that looks and tastes like UNISEPT® ORAL GEL without active ingredients

Device: Placebo Gel

Interventions

UNISEPT® ORAL GEL is an oral gel containing 10% w/v urea peroxide which releases 3.50% w/w hydrogen peroxide, glycerin, propylene glycol, carbopol, disodium EDTA, sodium saccharin, methyl salicylate, menthol, and water, serving as the active ingredient. Participants should apply the gel to the biopsy area and the corresponding sextant teeth three times daily, leaving it on for five minutes without rinsing, for a total of 14 days, beginning on day 0., i.e. the day of the biopsy (see procedure in the detailed description). Consumption of liquid or solid foods should be avoided for at least thirty minutes following gel application.Participants are asked to maintain their usual oral hygiene routine. UNISEPT® ORAL GEL is a Class IIa, CE-marked medical device made and distributed by Intermed S.A. and Ioulia And Irene Tseti Pharmaceutical Laboratories S.A.

Also known as: UNISEPT® ORAL GEL
UNISEPT® ORAL GEL

Placebo gel is a similar (look-and-taste-alike) product to UNISEPT® ORAL GEL, made by the same manufacturer, without active ingredients, containing glycerin, propylene glycol, carbomer, menthol, sodium saccharin, methyl salicylate, triethanolamine. Participants are called upon to apply the gel in exactly the same way as the experimental product, i.e apply the gel to the biopsy area and the corresponding sextant teeth three times daily, leaving it on for five minutes without rinsing, for a total of 14 days, beginning on day 0.
