Dr. Yoshihiro Shimazaki and his colleagues from Kyushu University in Fukuoka, Japan, found that regular green tea consumption helps in healthy teeth and gums promotion.  940 men aged from 49 to 59 with three indicators of periodontal disease were analyzed in this study.  The three indicators were periodontal pocket depth (PD), clinical attachment loss (CAL) of gum tissue, and bleeding on probing (BOP) of gum tissue.  The human subjects who were given a cup of green tea per day showed a significant reduce and improvement in periodontal disease compared to those who had less green tea.  Researchers believed that antioxidant catechin in the green tea which was previously proved having ability to reduce inflammation was responsible in promoting periodontal health as periodontal disease is chronic inflammatory diseases affecting gums and bones supporting the teeth.  Periodontal disease often linked with other diseases like cardiovascular disease and diabetes.

The study is published in the latest issue of American Academy of Periodontology’s (AAP) official publication, Journal of Periodontology.  Green tea is also beneficial in weight loss, heart health and cancer prevention.
