Researchers in Japan may have found a connection between individuals’ green-tea intake and periodontal health.
The study, conducted by researchers at Kyushu University in Fukuoka, Japan, and published in the Journal of Periodontology, analyzed comprehensive health evaluations performed on 940 men between the ages of 49 and 59. Subjects had at least 20 existing teeth and a high prevalence of periodontal diseases such as gingivitis and periodontitis.
Researchers found that the more a subject drank green tea, the better his periodontal health, even when accounting for in other lifestyle factors, such as smoking, drinking and tooth-brushing habits.
Such findings build on prior research, including in vitro studies suggesting that green tea catechins inhibit periodontal pathogens and the destruction of periodontal tissue. However, researchers acknowledged that the correlation between the two was generally weak and that many factors are at work in periodontal disease. They added that subsequent research on subjects’ overall diets and further studies on continued intake of green tea are necessary to strengthen interrelation.
