Assessing the Efficacy of a Carbamide Peroxide Mouthwash for Oral Wound Healing, Oral Hygiene and Xerostomia Relief

The experinmental mouthwah is a solution containing 4.3% w/v hydrogen carbamide, which breaks down to 1.51% w/v hydrogen peroxide, serving as the active ingredient. Participants rinse (swish and spit) with the mouthwash three times a day for one minute each time, using a 10ml quantity (as indicated by a marking line inside the bottle cap) for a total of 14 days, starting from 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 each rinse. Participants are asked to maintain their usual oral hygiene routine. It 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 mouthwash is a similar (look-and-taste-alike) solution to the experinmental mouthwash made by the same manufacturer, without active ingredients. Participants rinse (swish and spit) with the mouthwash three times a day for one minute each time, using a 10ml quantity (as indicated by a marking line inside the bottle cap) for a total of 14 days, starting from 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 each rinse. Participants are asked to maintain their usual oral hygiene routine.
