Every year, over 13 million people worldwide die from stroke. However, many of these incidents could be prevented through relatively simple means, such as a healthier diet, more exercise, or improved oral health.

As many as 25 per cent of the world's population will have a stroke at some point in their lives. While far from all of them are fatal, they can have far-reaching consequences for the individual.

Research shows that up to 90 per cent of strokes are preventable through lifestyle changes. These changes could involve eating better, exercising more or quitting smoking, which most of us are probably familiar with.

But there is a factor that has been shown to play a significant role in stroke patients - and which is perhaps a little more unknown.

- In our study, we found dental bacteria in the blood of four out of five stroke patients. These are bacteria that are naturally present in the mouth. Still, when they get into the bloodstream, they can lead to serious problems, says Olli Patrakka, a researcher at the University of Tampere, Finland.

Previous research has shown that there is a clear link between poor oral health and cardiovascular disease. For example, people who have periodontitis are 28 per cent more likely to have a heart attack. Now, we may be on to something similar when it comes to brain health and stroke.

- Although more studies are needed to establish causality, we now clearly see that dental bacteria also play a significant role in stroke patients. It may have a crucial role in prevention and treatment, says Olli Patrakka.

Stroke is common even in women

Generally speaking, stroke is usually described as something that mainly affects men. But this image is not entirely true. Sixty per cent of people who die from stroke are women, and in the age group 55 to 75, one in five women will have a stroke at some point.

However, because strokes are mainly thought to affect men, many women miss the symptoms, which can lead to seeking care later. Factors that increase the risk of having a stroke include high blood pressure, high blood lipids, smoking and diabetes. However, taking care of your oral health has also been shown to be essential for those who want to prevent stroke.

- The dangerous bacteria in our mouths usually stay there and initially cause 'only' tooth decay. But for those who have periodontal disease, the risk is that these bacteria can travel through the gums and into the bloodstream, says Tommi Pätilä, heart surgeon and founder of Koite Health.

Complementary treatment

The most important measure needed to prevent periodontal disease is regular cleaning of the teeth and the spaces between them. Brushing twice a day and using a floss or interdental brush daily flossing or interdental brushing is a good starting point.

However, mechanical brushing only removes about 65% of the bacteria found on teeth surfaces. A complementary treatment, such as Lumoral, is, thus, recommended for those who want to prevent tooth loss and other serious oral diseases.

Lumoral is a light-activated treatment that utilises a combination of two types of light to remove 99.99 per cent of the bacteria in dental plaque. It is easy to use and also makes it harder for new plaque to stick to teeth.

- Treatments of this type used to be performed only in clinics, but Lumoral has been developed for use at home. It is very effective, and many of my patients with a lot of tartar and inflammation of the gums have felt an incredible improvement after a few weeks of use, says Ing-Marie Albinsson, a dental hygienist at the Lilla Tandkronan clinic in Arvika, Sweden.

Those who play sports are at greater risk of dental diseases such as caries and periodontitis. Therefore, taking care of your oral health is particularly important because problems can also affect athletic performance.

Life as an athlete has many health benefits but can also have negative consequences. One is that those who play sports at a high level are more likely to have caries and inflammation of the gums, which can eventually lead to tooth loss.

There are several reasons for this. People who train hard need to eat more often, which strains the teeth. It is also not uncommon to need extra energy during training sessions, and many energy supplements, such as energy bars and drinks, are high in sugar.

Intense exercise also involves a high heart rate and intense breathing, often through the mouth. This reduces saliva production, making it easier for bacteria to attach to teeth.

Studies have shown that among athletes, as many as around 70% have caries, and 15% have periodontitis or tooth loss.

Oral bacteria migrate elsewhere to the body

Annimari Korte is a hurdler who has represented Finland in both the World Championships and the Olympics. She previously held the Finnish record in the 100-metre hurdles.

- It is well known that elite athletes are at greater risk of dental disease. The symptoms themselves can be troublesome and make training complex, but they can also affect the body physically in a negative way that reduces performance, she says.

For example, the link between more severe dental disease and cardiovascular disease is well documented. Studies have shown, for example, that people with periodontitis, i.e. 28 per cent more likely to have a first heart attack. And the symptoms are not always visible.

- The harmful bacteria in our mouths can travel through the inflamed gums and into the bloodstream. When the body's immune system recognises the dangerous bacteria, the reaction results in an inflammation process to fight the bacteria. The result can be, for example, an infection of the heart valves or inflammation of the heart vessels, says Tommi Pätilä, cardiac surgeon and founder of Koite Health.

Light-activated therapy is essential for a healthy mouth

Exercising hard with low-grade inflammation in the body can involve significant risks. This is one reason why high-level athletes need to monitor their oral health.

- Because many oral conditions that can be detrimental to elite athletes are asymptomatic, it is essential to visit the dentist or dental hygienist frequently. This way, you can detect problems in time, says Annimari Korte.

To prevent oral infections and dental diseases, the most important thing to do is to brush your teeth thoroughly twice a day and clean between the teeth with floss or interdental brushes. Taking some form of fluoride treatment daily is also a good tip.

Manual toothbrushing is not, however, perfect—studies have shown that it only removes 65 per cent of the harmful bacteria on your teeth—it can be helpful to use a supplement, such as Lumoral therapy. Lumoral uses a patented light-activated therapy that removes 99.9% of the harmful bacteria on the tooth surface.

- I have been using Lumoral for a year and a half now, and my gums are in much better shape today. They no longer bleed when I clean between my teeth, and I have not had a cold since then. This has allowed me to train very effectively, and recently, I did my fastest time in three years, 12.83 seconds, says Annimari Korte.

Lumoral

The Lumoral method removes microscopic plaque from the teeth and gums' surface, slowing down the formation of new plaque and tartar. Its effect is based on the light-activated Lumorinse mouthwash. The treatment targets its antibacterial effect only on plaque and thus favours the normal bacterial flora in the mouth. Lumoral is a CE-marked medical device.

Lumoral consists of a mint-flavoured mouth rinse, Lumorinse, which is combined with the special mouthpiece. Using a method resembling photosynthesis, the treatment eliminates the ability of plaque to adhere to its substrate, which means that the teeth are cleaned, and the tooth surface becomes smooth.

The treatment, which can be performed at home, takes 10 minutes and is recommended once or twice a week.

Lumoral Junior

For children, there is Lumoral Junior, which includes a mouthpiece adapted for children's needs.

It is suitable for children between 4 and 12 years old. From the age of 12, children can usually switch to using a Lumoral mouthpiece, which is ideal for adults. To use Lumoral, the child should be able to rinse their mouth with mouthwash.

The Nokia Rubber Workers' Sickness Fund (Nokian Kumiväen Sairauskassa) has entered into a partnership agreement with Finnish health technology company Koite Health Oy, deciding to increasingly focus on the oral health of its insured members. The fund will now reimburse the costs of Lumoral treatment for its insured members, providing a valuable additional benefit for maintaining oral health.

Lumoral is an innovative Finnish health technology solution that supports users' oral health by treating and preventing infections of the teeth and gums. The fund sees its solution as an important step towards preventive healthcare.

– The decision is based on thorough consideration and discussions with the fund's board. The board recognized the opportunities offered by the Lumoral device and unanimously decided to approve it as part of the benefits offered by the sickness fund, says Piia Virolainen, CEO of the Nokia Rubber Workers' Sickness Fund.

Studies show that poor oral health is one of the major risk factors behind many common diseases, as inflamed gums and damaged tooth surfaces provide a direct route for bacteria.

– Oral infections are remarkably common globally, and they contribute to the onset of serious conditions such as cancer, diabetes, heart, lung, and kidney diseases, says Tommi Pätilä, a heart and organ transplant surgeon at HUS Children's Hospital, in Helsinki. Pätilä is also one of the developers of the Lumoral method.

– As the population ages, we are inevitably heading towards difficult times in healthcare and its financial management. Oral infections significantly increase the need for hospitalization and its complications. Therefore, investing in oral care and its comprehensive understanding – especially in the prevention of dental diseases – pays off multiple times in the future, Pätilä continues.

Oral diseases are a significant expense

According to Virolainen, the decision will practically mean that regular Lumoral treatment, including Lumorinse tablets, will be covered for the health fund's insured members as part of the fund's dental benefit.

– Regular Lumoral treatment has an impact on oral health, but it also affects the overall well-being of its users. The Nokia Rubber Workers' Sickness Fund is constantly striving to improve the well-being and health of its insured members. The reimbursement of Lumoral device and Lumorinse tablets is one step towards this goal, emphasizes Virolainen.

Virolainen states that the Nokia Rubber Workers' Sickness Fund reimburses the most research and treatment costs. The next highest reimbursement is for insured members' dental treatment costs.

– Dental diseases can lead to significant costs, making our fund's dental benefit a highly valued and frequently utilized resource among our insured members. Quick access to dental care, without the inconvenience of waiting, is considered essential by our insured members, Virolainen adds.

According to Lumoral Area Manager Riikka Nisula, local dental clinics have eagerly welcomed the decision of the Nokia Rubber Workers' Sickness Fund to reimburse Lumoral and Lumorinse tablets because prevention and enhancing self-care support professional treatment.

The antibacterial Lumoral treatment effectively removes harmful bacteria from the surfaces of the teeth and gum lines. Home-administered Lumoral treatment has been found to be significantly more effective and better tolerated than chlorhexidine-based mouthwashes, which are commonly used today.

Nisula emphasizes that the antibacterial treatment is carried out as an additional treatment to mechanical teeth cleaning and does not replace the need to brush teeth and clean between teeth. So why is additional treatment to enhance mechanical oral hygiene needed?

According to studies, brushing teeth removes only 65% of plaque. Residual plaque remains in the mouth after even the most effective teeth brushing. Lumoral helps to remove this residual plaque. With regular Lumoral treatment, the tooth surfaces are properly cleaned.

Antibacterial treatment has also been shown to prevent and treat infections of the tissues surrounding implants. The treatment is suitable for everyone, but light-activated antibacterial treatment is seen as most effective for patients who need enhanced oral hygiene.

The Nokia Rubber Workers' Sickness Fund is a so-called supplementary fund that reimburses insured members for additional benefits according to its rules. The fund has about 1,200 insured members. Altogether, there are about 110 health funds operating in Finland, whose insured members consist of employees and/or office personnel. In many funds, retirees can continue to be insured by the fund, and in some funds, family members are also entitled to reimbursements.
