A plaster which sticks to the inside of your mouth is revolutionising the treatment of painful recurring ulcers.
Scientists from the University of Sheffield's School of Clinical Dentistry, working in close collaboration with Dermtreat A/S from Copenhagen, have developed a unique patch using special polymers which are able to stick to moist surfaces.
The patch successfully administers steroids directly to oral ulcers or lesions whilst also creating a protective barrier around the affected area, accelerating the healing process.
The novel plaster is a breakthrough therapy for the treatment of mucosal conditions such as oral lichen planus (OLP) and recurrent aphthous stomatitis (RAS), which are diseases that cause painful lesions and affect 1-2 per cent of the population.
Until now, ulcers and lesions inside the mouth have been treated using either creams or mouthwashes, which are used in the whole mouth rather than targeting the specific area, making them less effective. However, the biodegradable Rivelin® patch, has a long adhesion time and a high flexibility which conforms to the surface inside the mouth.
Dr Craig Murdoch, Reader in Oral Bioscience School of Clinical Dentistry and lead author of the research, said: "Chronic inflammatory conditions such as OLP and RAS, which cause erosive and painful oral lesions, have a considerable impact on quality of life.
