Influence of oral rehabilitation to home bedridden elderly people exerts in general status

老年人在日本人口比例中的比例每年都在增加。2020年，日本65岁或以上的人口将占33%。因此，改善老年人的口腔健康成为一个重要的问题。本研究的目的是研究口腔康复对老年人咀嚼运动、吞咽和生命功能(如ADL等)的影响。本研究首先对100岁及以上老年人进行问卷调查，结果表明口腔健康程度与生命反应(ADL和QOL)有很强的相关性。其次，开发了可用于咀嚼能力测量的口香糖。利用这种口香糖让受试者做咀嚼运动。同时测量口腔周围肌肉的血流量变化。结果是血流量增加。同时测定当时的唾液分泌量。结果是分泌量增加。这一变化在当时的唾液元素中得到了承认。

The ratio of senior citizens in the population ratio of Japan increases every year. In 2020, the population with 65 years old or more of Japan becomes 33%.
