In recognition of World Oral Health Day on March 20th today’s post will examine the relationship between periodontal disease and prehypertension, as well as hypertension.

According to statistics from the CDC, more than 25% of the adults in the U.S. have untreated tooth decay. In addition, almost half of U.S. adults have some signs of gum disease. Periodontitis is defined as the inflammation of the gums and support structures of the teeth. It is caused by certain bacteria, and in turn these bacteria cause inflammation. It is thought that perhaps if this inflammatory state becomes chronic, it may have implications for inflammation elsewhere in the body, such as in cardiovascular health.

A research group in Japan performed a prospective cohort study on a group of university students, examining whether periodontal disease was related to the development of prehypertension, or to hypertension. Over 2500 students enrolled in the study, ages 18-27 years.

Dentists assessed the oral health of each student. Periodontal health was evaluated using the Community Periodontal Index (CPI), which is commonly used to measure periodontal disease. The CPI is an objective measure of periodontal health, and also suggests the proper treatment for the given CPI score. In addition to the CPI, the dentists also measured the Bleeding Upon Probing (BOP), which is felt to be a simple way to assess inflammation. While dentists assessed oral health, the resting blood pressure and body mass index of the subjects was also measured. The participants also completed a questionnaire, which assessed both dental and general health measures.

The Japanese university students were followed over a period of three years. What the researchers discovered was that the risk of developing hypertension over the three years was significantly associated with periodontal disease.

Given the results of this study, consider practicing good oral health as a way to lower your risk for developing high blood pressure. And don’t forget to thank your dentists and hygienists on World Oral Health Day, or the next time you see them.
