People who keep their teeth and gums healthy with regular brushing may have a lower risk of developing dementia later in life, according to a US study.

Researchers at the University of California who followed nearly 5,500 elderly people over an 18-year period found that those who reported brushing their teeth less than once a day were up to 65 percent more likely to develop dementia than those who brushed daily.

“Not only does the state of your mind predict what kind of oral health habits you practice, it may be that your oral health habits influence whether or not you get dementia,” said Annlia Paganini-Hill, who led the study published in the Journal of the American Geriatrics Society.

Inflammation stoked by gum disease-related bacteria is implicated in a host of conditions, including heart disease, stroke and diabetes. Some studies have also found that people with Alzheimer’s disease have more gum disease-related bacteria in their brains than a person without Alzheimer’s, Paganini-Hill said.

根據美國研究,規律刷牙保持牙齒與牙齦健康的人,老年罹患失智的風險較低。

加州大學研究人員在十八年間追蹤五千五百名年長者,發現每天刷牙少於一次者,失智風險比每天刷牙者高百分之六十五。

主持這項研究的巴加尼尼—希爾,在《美國老人醫學學會期刊》發表研究說:「不只是心理狀態可預測你的口腔健康習慣,你的口腔健康習慣也會影響會不會失智。」

牙齦疾病相關細菌引起的發炎,與心臟病、中風與糖尿病等許多疾病密切相關。巴加尼尼—希爾說,部分研究也發現,阿茲海默氏症患者,腦中與牙齦疾病相關的細菌,多於非阿茲海默氏症患者。
