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

老年人在日本人口中所占的比例每年都在增加。到2020年，日本65岁以上的人口将达到33%。因此，改善老年人的口腔健康成为重要的课题之一，本研究的目的在于探讨口腔复健对老年人咀嚼运动、吞咽及生活功能（如日常生活活动能力等）的影响。本研究首先对100岁以上的老年人进行问卷调查，结果表明口腔健康程度与生命反应有很强的相关性（ADL和QOL）。接下来，开发了能够用于咀嚼能力测量的口香糖。通过使用该口香糖，使受试者进行咀嚼运动。此时，测量口腔周围肌肉的血流量变化，结果血流量增加，同时测量此时分泌的唾液，结果分泌量增加。这种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%. Therefore, the improvement of the health of senior citizen's mouth becomes one of the important problems.The purpose of this research is that rehabilitation in the mouth examines the influence given to the Masticatory movement, the Swallowing, and the vital function (for instance, ADL etc.). In this research, the questionnaire survey intended for the senior citizen of 100 years or more was done first.As a result, the health degree of the mouth had a strong connection in the vital reaction (ADL and QOL).Next, the chewing gum that was able to be used for the chewing ability measurement was developed.The subjects are made to do the chewing movement by using this.At this time, the change in a blood flow volume muscular in the mouth surroundings was measured.As a result, the blood flow volume has increased.The saliva secreted at that time was measured at the same time.As a result, the amount of the secretion has increased. The change was admitted in the element of the saliva at that time.
