Cleaning your teeth often, every day, is linked to a lower risk for heart problems. A new study found that brushing your teeth several times a day resulted in fewer cases of heart failure and atrial fibrillation— the term for an uneven heartbeat.

每天经常刷牙可以降低患心脏病的风险。一项新的研究发现,每天刷牙几次可以减少心力衰竭和房颤,房颤是指心跳不均匀的术语。

Heart failure happens when the heart cannot do its job of pumping blood through the body.

心力衰竭发生是指在心脏不能完成泵血功能。

What the research found is that brushing your teeth three times a day, or more, was linked to a ten percent lower risk of atrial fibrillation. It was also linked to a twelve percent lower risk of heart failure.

研究发现,每天刷牙三次或更多,可以降低10%的房颤风险。它还可以降低12%的心脏衰竭风险。

The study was published last Monday in the European Journal of Preventive Cardiology.

这项研究于上周一发表在《欧洲预防心脏病学杂志》上。

The researchers examined information on more than 161,000 people in Korea with no history of heart problems.

研究人员调查了超过16.1万名没有心脏病史的韩国人的信息。

They followed up ten and a half years later, and found that three percent had developed uneven heart rhythms and almost five percent had developed heart failure.

他们在10年半后进行了跟踪调查,发现有3%的人出现了心律不齐,近5%的人出现了心力衰竭。

All the participants in the study were part of the Korean National Health Insurance System, and aged 40 to 79. They had usual medical exams between 2003 and 2004. Information was collected on their height, weight, laboratory tests, sicknesses, and lifestyle. They also noted their mouth health in connection with cleaning.

研究的所有参与者都是韩国国民健康保险系统的一部分,年龄在40岁到79岁之间。他们在2003年到2004年间进行了常规的医学检查。研究人员收集了他们的身高、体重、实验室检测、疾病和生活方式等信息。他们还注意到了清洁口腔的好处。

Heart and teeth health connection

心脏和牙齿的健康联系

You may wonder, how are teeth health and heart health connected?

你可能想知道,牙齿健康和心脏健康是如何联系在一起的?

Earlier research suggests that not taking care to clean and brush teeth leads to bacteria in the blood. This can cause inflammation, and increases the risk for unusual heartbeat and heart failure.

早期的研究表明,不注意清洁和刷牙会导致血液中的细菌。这会引起炎症,增加心跳不齐和心力衰竭的风险。

A study last year by the American Heart Association showed that brushing your teeth twice a day for at least two minutes may lower the risk of cardiovascular, or heart, diseases.

美国心脏协会去年的一项研究表明,每天刷牙两次,每次至少两分钟,可以降低患心血管疾病或心脏病的风险。

That study looked at a smaller group of fewer than 700 people. The AHA said that the researchers found that people who brushed less than twice a day for less than two minutes were three times more at risk, compared to those who brush at least twice a day for two minutes.

这项研究调查了少于700人的小群体。美国心脏协会表示,研究人员发现,与每天至少刷牙两次、每次刷两分钟的人相比,每天刷牙不到两次、每次刷低于两分钟的人患心脏病的风险要高出三倍。

Gums are the soft tissue structure that hold the teeth. They need to be cleaned as well. Experts say if gums are not cared for this way they can become inflamed. They say there is a connection between such inflammation, and future heart disease.

牙龈是支撑牙齿的软组织结构,也需要清洗。专家表示,如果不这样护理牙龈,它们可能会发炎。这种炎症和心脏病之间有联系。

The lead investigator of the new study is Tae-Jin Song, a doctor and professor at Mokdong Hospital at Ewha Womans University in Seoul, South Korea. He noted "we studied a large group over a long period, which adds strength to our findings."

这项新研究的首席研究员是韩国首尔梨花女子大学莫克东医院的教授宋泰镇医生。他指出,“我们对一个大群体进行了长时间的研究,这为我们的发现增添了力量。”

But he said that the research was limited to one country and as an observational study does not prove causation.

但他说,这项研究仅限于一个国家,作为一项观察性研究,并不能证明因果关系。

The American Dental Association agrees. The organization said "this study is interesting, and while it may suggest an association between tooth brushing and heart health, it does not show a direct connection."

美国牙科协会对此表示赞同。该组织说:“这项研究很有趣,虽然它可能表明刷牙和心脏健康之间存在联系,但并没有直接联系。”

To have good oral health, the ADA advises people to:

为了拥有良好的口腔健康,美国口腔协会建议人们:

  • Brush their teeth twice a day for two minutes each time with a fluoride toothpaste
  • 每天用含氟牙膏刷牙两次,每次两分钟
  • Clean between their teeth once per day
  • 每天清洁牙齿一次
  • Maintain a healthy diet
  • 保持健康饮
  • See a dentist regularly
  • 定期看牙医

Mouth care companies have taken note. Some manufacture electric toothbrushes programmed to run for two minutes. That way, people do not have to watch the time while brushing their teeth.

口腔护理公司已经注意到了这一点。一些制造电动牙刷的程序运行两分钟。这样,人们刷牙时就不必看时间了。
