Abstract

<p>Membranous substances, which are not observed in healthy individuals, are sometimes observed in the mouths of elderly persons requiring nursing care. These are often reported to be in the form of a crust or sputum, but there are reports suggesting that they are actually a peeling epithelial membrane. This latter description is based on the fact that epithelial components exhibiting a layered structure with a stratum corneum have been seen in pathological observation of these membranes. One of the risk factors for developing membranous substances was reported to be dryness of oral membrane. An effective method for suppressing the formation of membranes is not clear. The intervention of oral care (tooth-brushing and application of gel-type moisturizer) by a dentist and spraying of moisturizer by nurses was examined to determine the effectiveness on suppressing membrane formation.</p><p>The subjects were 27 elderly patients requiring nursing care in hospital A in Nagano prefecture and hospital B in Yamanashi prefecture. All study subjects were bedridden and assisted tooth-brushing was carried out twice a day. The intervention of oral care (tooth-brushing and application of gel-type moisturizer twice a week) by a dentist was carried out, and spray moisturizer (liquid type) was applied by the nurses more than five times a day.</p><p>The liquid-type moisturizer was sprayed by the nurses an average of 6.9±5.3 times a day. The presence of membranous substances was observed at the baseline (pre-intervention): in the buccal mucosa in one person, on the tooth surface in 2, on the tongue in 5, and on the palate in 7. Of the 10 patients who had membranous substances formed at the baseline, the membranous substances were suppressed by intervention after one week in 5 patients (50%). Thus, formation of membranous substances was significantly reduced by the intervention.</p><p>In order to suppress the formation of membranous substances, it is clear that the use of moisturizer in addition to assisted tooth-brushing is effective.</p>
