Oral health linked to increased dementia and hypertension risks

Recent Japanese studies have highlighted significant links between oral health and systemic conditions, including dementia and hypertension.

A decade-long study following nearly 1,400 Japanese adults suggests that severe gum bleeding and gum recession are major risk factors for dementia. According to research published in The Journal of Clinical Periodontology, individuals with the most severe gum bleeding faced a 56% higher risk of developing dementia and a 61% higher risk of Alzheimer's disease. Furthermore, those with significant gaps between their teeth and gums showed a 72% increased risk. Researchers believe inflammatory processes triggered by oral microbes may be a contributing factor.

In a separate study, researchers from Temple University's Lewis Katz School of Medicine found that a concentrate of Japanese plum juice may help prevent high blood pressure. In animal trials, mice treated with the concentrate did not develop hypertension, as the juice appeared to protect blood vessels from the harmful effects of the hormone angiotensin II. While these results are promising for cardiovascular health, scientists note that further research is required to determine if these effects translate to humans.
