A Randomized Placebo-Controlled Clinical Trial Assessing the Efficacy of a Carbamide Peroxide Mouthwash for Oral Wound Healing, Postoperative Symptoms, Xerostomia Relief, and Oral Hygiene Following Diagnostic Biopsy of Minor Labial Salivary Glands for Sjögren's Syndrome Investigation
In Brief
A clinical study evaluating Carbamide Peroxide Mouthwash and Placebo mouthwash for Wound Heal and 8 related conditions. Completed, enrolled 54 participants across 1 site.
Detailed Summary
The aim of this study is to evaluate the efficacy and safety of a carbamide peroxide mouthwash regarding oral wound healing, postoperative symptoms, xerostomia (dry mouth) and oral hygiene improvement. Study participants have reported dry mouth and are scheduled for a diagnostic biopsy of minor labial salivary glands to investigate Sjögren's Syndrome, following consultation with their rheumatologist. This is a standardized diagnostic procedure that leads to healing by primary intention (i.e. wound edges are closely re-approximated with sutures). Researchers are comparing this mouthwash 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 dry mouth and/or oral hygiene. Carbamide peroxide breaks down to hydrogen peroxide and urea and shows antiseptic and antimicrobial properties and it might help with the parameters to be assessed. Participants randomly get the carbamide peroxide mouthwash or the placebo one to use for 14 days after the biopsy. The investigators will not know which one they are providing as the bottles will be identical. Oral wound healing, postoperative symptoms (such as pain, eating and speech difficulties), oral hygiene (dental plaque and gingival inflammation), improvement of dry mouth 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 consultation and the biopsy, one at 7 days and one at 14 days after the biopsy. They are asked to fill in some questionnaires, while certain procedures (such as measuring saliva) 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.

Interventions
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.
