It is said that more than 40% of Japanese patients with periodontal disease are over 8 years old, which accounts for 4% of the causes of tooth loss.Chronic periodontitis is an inflammation caused by the bacteria that cause periodontal disease, and is a disease that becomes acute due to a decrease in resistance.When chronic periodontitis becomes acute for some reason, the tissues around the teeth are rapidly destroyed.Therefore, it is important to predict the acuteization of chronic periodontitis from the viewpoint of tooth preservation.

　It has been pointed out that changes in the weather may cause or worsen the symptoms.Therefore, Professor Morita et al. Investigated a total of 2 patients with chronic periodontitis in the stable period and investigated the relationship between periodontal disease and meteorological changes.By analyzing the results side by side as numerical values ​​over time, we found that acute symptoms are likely to occur 1 to 3 days after a large decrease in atmospheric pressure or temperature rise.The detailed mechanism is unknown, but it is thought that changes in atmospheric pressure and temperature may affect hormone secretion and the circulatory system.

　In this study, it was found that the meteorological conditions related to the acuteization of chronic periodontitis include a decrease in atmospheric pressure and an increase in temperature.In the future, we will investigate how much change will cause pain and swelling.As research progresses, we can expect the realization of an outbreak forecast in the acute phase.Similar techniques may also be used to predict symptoms of blood pressure, myocardial infarction, asthma, rheumatism, depression, etc., which have been confirmed to be associated with the weather.
