Description

<p>　Recently, jellies and commercial thickening agents have been widely utilized among elderly people with swallowing difficulties. The aim of this study was to clarify the effect the ingestion of supplementary food for swallowing disorders has on oral hygiene.</p><p>　Thirteen healthy adults without swallowing difficulties were subjects in this study. They were evaluated regarding their intraoral residues after taking test foods (cookie, jelly, thickened water) by measuring the optical density of liquid after mouth rinsing of water. The experimental conditions such as amount, duration, swallowing, and chewing were strictly limited to simulate patients with dysphagia.</p><p>　As a result, ingestion of jelly or thickened water after taking a cookie reduced the intraoral residue significantly. Among several conditions tested, chewing was very efficient to reduce the intraoral residue. In conclusion, it is suggested that the ingestion of jelly with chewing after a meal might improve oral hygiene in people with a decreased deglutition function, in addition to prevent aspiration of residual debris. Furthermore, we should consider not only the texture of food but also the way to eat it for the maximum effect of intraoral residue removal.</p>
