This study looks at a new way to treat minor recurrent aphthous ulcers. These ulcers are painful, round or oval sores that show up on the soft, non-chewing surfaces of the mouth (like the inside of the cheeks or lips). While they are not dangerous, they cause severe pain and make eating, talking, and swallowing difficult.
The current standard treatment is usually a topical steroid gel called triamcinolone acetonide, which helps reduce pain and swelling but can have limitations. This clinical trial is testing whether a novel topical probiotic gel can work just as well as the steroid gel to speed up healing, lower pain, and reduce local inflammation.
Additionally, the study will measure a molecule found in saliva called microRNA-146a. This molecule acts as a natural biological marker that tracks how well the mouth tissue is healing from inflammation
