[The effect of "Oral Wet" for elderly people with xerostomia--the effect of oral rinse containing hialuronan].

Japanese society is aging rapidly, and the number of elderly people is increasing, hence the number of elderly people who have some diseases or disorders is growing. Therefore, Japanese dentists have to cope with various oral symptoms along with aging. Xerostomia is one of the most common symptoms of the elderly, but there is no established treatment. We tried to use an oral rinse "Oral Wet" that contains hialuronan and xylitol for elderly nursing home residents and examined the effect for Xerostomia. The usage of Oral Wet improved hyposalivation and unpleasant oral complaints of the elderly.
