Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All biopsies are obtained from the gingiva or hard palate with a sterile disposable or reusable punch of 4,6 or 8mm in diameter, resulting in the extraction of similar tissue cylinders.The punch is grasped between the index and thumb, supporting the cylinder over the target lesion. Healing by secondary intention follows, as suturing of the residual wound is not necessary, and the bleeding can be contained by simply applying a piece of gauze.
Participants are instructed to have cold and soft diet for the day. Use of 500mg paracetamol up to 3 times is permitted for day 0. Following their normal oral hygiene routine (brushing and toothpaste) is suggested.
Subsequently, they are assigned randomly in a 1:1 ratio to receive either a hydrogen carbamide/peroxide gel (UNISEPT® ORAL GEL - Intermed S.A. and Ioulia And Irene Tseti Pharmaceutical Laboratories S.A) or a placebo comparator, i.e. a look-alike substance that lacks active ingredients (such as hydrogen carbamide/peroxide). Both participants and investigators are masked. Follow-up examinations are conducted at 7 and 14 days.
The evaluation includes:
oral wound healing (secondary intention) assessed by percentage healing index (PHI)(primary outcome)
and secondary outcomes: oral wound healing assessed by clinical parameters (such as redness, oidema, pus discharge) postoperative symptoms (such as pain, eating and speech difficulties) quality of life assessed by a questionnaire oral hygiene via plaque and gingival indices.
All data are anonymized and the outcome assessors are masked.
UNISEPT® ORAL GEL is a Class IIa, CE-marked (Conformité Européenne) medical device. This gel contains hydrogen carbamide that breaks down to hydrogen peroxide, which has antiseptic and antimicrobial properties. These substances have been used in wound healing either in skin or intraorally, as well as in oral hygiene for a long time. However, to date, there is no clinical trial examining the use of a hydrogen carbamide/peroxide product in oral wound healing and postoperative symptoms. Published clinical studies on the control of dental plaque and periodontal inflammation exhibit partially conflicting results.

Study Groups

UNISEPT® ORAL GEL
A gel containing hydrogen carbamide/peroxide as active ingredient
Hydrogen Carbamide/Peroxide Gel
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.
PLACEBO
A gel that looks and tastes like UNISEPT® ORAL GEL without active ingredients
Placebo 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.
