Effect of Applying Oral Hygiene Care on Swallowing in Stroke Patients With Oropharyngeal Dysphagia

This intervention will include mouth cleaning with water and gauze to remove plaque and debris. Water-based hydrating gels (bioXtra Dry Mouth Oral Gel, Lifestream Pharma N.V., Seneffe, Belgium) will be then applied to all oral structures, including the lips, tongue, palate, and cheeks, using gloved fingers or a small toothbrush. In the presence of dried secretions, the gels will be massaged into these areas and left to act for a few minutes to facilitate removal and reduce patient discomfort.

Patients with natural teeth will be treated using a soft toothbrush and a sodium lauryl sulfate-free fluoride toothpaste (meridol® toothpaste, Colgate-Palmolive Company, Belgium). The teeth will be brushed using the modified BASS technique. Subsequently, the tongue will be cleaned with either a scraper. For participants wearing dentures, the dentures will be cleaned using a denture brush and soap.

Patients will receive a comprehensive oral hygiene intervention incorporating mouth cleaning, mechanical oral hygiene, and moisturization. The procedure will begin with oral cleaning using water and gauze, followed by mechanical oral hygiene, and conclude with the application of the hydrating gel.
