The person who 65-years-old or more senior citizen it, hardly had teeth by him, and was not using his artificial tooth had the report that the research group of the Ministry of Health, Labour and Welfare had brought the result of the survey that the probability of getting a dementia compared with the person who had 20 teeth or more increased by a factor of 1.9 together.
As for a person not dentate, the probability of getting a dementia rises.
In this investigation, the research group of the Ministry of Health, Labour and Welfare is the one that the pursuit investigation was done for four years for 65-years-old or more about 4500 senior citizens who live in Aichi Prefecture.
The risk of getting a dementia seems to have increased in the person who compared with the person who had his 20 teeth or more few teeth, and was not using his artificial tooth by a factor of 1.9 as a result.
It rose to 1.2 times in the person who few teeth, and was using his artificial tooth. Moreover, the person who was not able to bite a hard thing seems to have been 1.5 times as high as the person who was able to bite any one.
It is thought that the risk of the dementia rises in a senior citizen not dentate because stimulation to the brain is lost due to the decrease in the relation to the cerebral infarction that periodontitis becomes the cause of the dementia, and power to bite.
Periodontitis and lifestyle disease
Moreover, it has been understood to relate periodontitis, the heart attack, the cerebral infarction, the diabetic, and the premature delivery, etc.It is possible to think this to be a rise of the risk of the dementia because of the loss of teeth such as periodontitis like the above-mentioned.
The numbers of teeth of the average that remains in 75-years-old or more person are called nine. Stimulation is transmitted from not only the function to bite the thing with teeth but also the periodontal membrane to the brain through the nerve. It is thought that the brain is activated by the stimulation when this food is crunched, and the blood flow volume increases.
