Professor Renki Kobayashi of the Graduate School of Medicine, the University of Tokyo and Nakanishi, a dental equipment manufacturer (Kanuma City, Tochigi Prefecture, President Eiichi Nakanishi), explained the causes and effects of oral diseases such as tooth decay and periodontal disease, and arteriosclerosis and myocardial infarction. We have started a joint research to investigate the relationship.Dental examinations and health examinations will be conducted for all 880 Nakanishi employees, and long-term analysis will be carried out in Professor Kobayashi's public health class.

According to Nakanishi, the company has set up a new dental examination center at its headquarters in Kanuma City.In addition to dispatching dentists from the Kanuma Dental Association, which cooperates in joint research, we will provide a maximum of 1 yen per employee per year and oblige all employees to undergo a dental examination once a year.We will analyze the obtained dental examination and health examination data at the Kobayashi laboratory of the University of Tokyo to explore the causal relationship between the condition of the oral cavity and health.
Oral diseases such as tooth decay and periodontal disease are said to be one of the factors that cause heart and vascular diseases such as arteriosclerosis and myocardial infarction.This is because it is thought that when bacteria and inflammatory substances related to periodontal disease enter the blood vessels, they promote arteriosclerosis.It has also been reported that periodontal disease increases the risk of heart disease by 1% to 15%.
However, few studies have proved a causal relationship between the two. It seems that highly accurate research results can be expected because the examination data of nearly 900 people will be collected over a long period of time.

Nakanishi said, "We want to clarify that managing oral health has a great impact on maintaining health in old age, and not only improving the health of employees, but also maintaining the health of society as a whole." increase.
