Older adults with poor cognitive function are found to have impaired oral health and higher risk of tooth loss later, says a study.
According to the study, there was a clear association between cognitive function and tooth loss when cognitive function score was categorised into quintiles.
The study, published in the Community Dentistry & Oral Epidemiology, showed people in the lowest quintile reflecting poorer cognitive function had 39 per cent higher odds of tooth loss than those in the highest quintile.

“The findings indicate that an improvement in cognitive function could potentially improve oral health and reduce the risk of tooth loss in the ageing population,” said Wu.

“Our study suggested a close link between cognitive function and oral health in older adults,” said Jianhua Wu, Researcher at the University of Leeds in Britain.
“The findings indicate that an improvement in cognitive function could potentially improve oral health and reduce the risk of tooth loss in the ageing population,” said Wu.
The study included 4,416 adults aged 50 years and above.
According to previous studies, older adults with just 10-19 teeth are at a higher risk of malnutrition in addition to higher rates of weight loss and lower appetite. They are also at increased risk for dementia and/or depression. (IANS)

Brushing Teeth Frequently May Lower Risks of Heart Failure: Study

Brushing teeth 3 times a day can lower heart failure risk

Brushing teeth frequently is linked with lower risks of atrial fibrillation and heart failure, according to a new study.

Tooth brushing three or more times a day was associated with a 10 per cent lower risk of atrial fibrillation and a 12 per cent lower risk of heart failure during 10.5-year follow up, the research added.

The study, published in the European Journal of Preventive Cardiology, enrolled 161,286 participants of the Korean National Health Insurance System aged 40 to 79 with no history of atrial fibrillation or heart failure.

“We studied a large group over a long period, which adds strength to our findings,” said study author Tae-Jin Song of Ewha Woman’s University in South Korea.

Previous research suggests that poor oral hygiene leads to bacteria in the blood, causing inflammation in the body.

Inflammation increases the risks of atrial fibrillation (irregular heartbeat) and heart failure (the heart’s ability to pump blood or relax and fill with blood is impaired).

This study examined the connection between oral hygiene and occurrence of these two conditions.

Participants underwent a routine medical examination between 2003 and 2004. Information was collected on height, weight, laboratory tests, illnesses, lifestyle, oral health, and oral hygiene behaviours.

During a median follow-up of 10.5 years, 4,911 (3.0 per cent) participants developed atrial fibrillation and 7,971 (4.9 per cent) developed heart failure.

The findings were independent of a number of factors including age, sex, socioeconomic status, regular exercise, alcohol consumption, body mass index, and comorbidities such as hypertension.

According to the researchers, while the study did not investigate mechanisms, one possibility is that frequent tooth brushing reduces bacteria living in the pocket between the teeth and gums, thereby preventing translocation to the bloodstream.

It is certainly too early to recommend toothbrushing for the prevention of atrial fibrillation and congestive heart failure, the study said.

“While the role of inflammation in the occurrence of cardiovascular disease is becoming more and more evident, intervention studies are needed to define strategies of public health importance,” it added. (IANS)
