World Heart Day, launched by the World Heart Federation (WHF), is celebrated each year on the 29th of September. The global event aims to raise awareness and encourage action for heart health.
Cardiovascular disease (CVD) is the leading cause of death in the Western world. The most common cardiovascular diseases are coronary heart disease, heart failure, and cerebrovascular disorders. More than 20.5 million people die from these diseases each year. Cardiovascular diseases affect the heart and blood vessels, leading to severe and possibly even fatal complications. However, the WHF estimates that 80% of premature deaths from the disease are preventable (1).
– By making small changes to our lifestyles, we can better manage our heart health and beat cardiovascular disease, the WHF encourages.
Such changes include actions that help improve oral health. Good oral hygiene is more than just a beautiful smile. It is essential to look after your teeth and mouth because even seemingly harmless oral conditions can put you at risk of serious diseases.
Oral pathogens are not limited to the mouth
Tommi Pätilä, a cardiac and transplant surgeon at the New Children’s Hospital (HUS), stresses that a healthy heart requires a healthy mouth and thorough daily oral hygiene. Oral biofilm bacteria are the cause of 95 percent of dental diseases.
– Simple measures such as regular brushing and cleaning of the interdental spaces and regular dental check-ups can help prevent the onset of gum disease and, at the same time, minimise the risk of bacteria or their structures in the mouth entering the bloodstream and spreading to the rest of the body, says Pätilä.
Even chewing food can spread bacteria or parts of bacteria that cause oral infections to the rest of the body through infected gums. This results in a persistent inflammatory condition within the body, which may subsequently give rise to serious health conditions, including cardiovascular disease, Pätilä notes.
– On the other hand, sudden problems occur when live bacteria infect the heart valves, Pätilä continues.
In 2016, Pätilä operated on a severe bacterial heart valve infection and was motivated to make a difference in oral health.
– It turned out that the cause of the patient’s severe heart infection was bacteria from the mouth. At that point, I knew something had to be done to combat the residual plaque that causes disease and plagues in peoples’ mouths despite brushing and flossing.
Pätilä is one of three Finnish researchers who have developed the antibacterial Lumoral method. Lumoral is a patented medical device that treats and prevents oral diseases at home. The Lumoral treatment can remove 99.99% of plaque bacteria from the tooth surface (2).
Prevention and early diagnosis pays off
– In contrast to commonly held beliefs, a toothbrush is only capable of eliminating approximately 60% of oral biofilm. It's no surprise then that cavities and gingivitis stand as the most prevalent diseases worldwide. If we want to improve oral health outcomes, we need to tackle the plaque left behind by tooth brushing, says Timo Sorsa, Professor of Oral and Maxillofacial Diseases at the University of Helsinki.
In Finland, it is estimated that up to two out of three people over 30 suffer from periodontitis. This common gum disease can lead to tooth loss if left untreated – but it is also linked to severe heart events. According to a study, individuals with periodontal disease are 30% more likely to experience a first heart attack compared to their healthy counterparts of the same age (3).
According to another study published in the Journal of Periodontology, people with periodontal disease were almost twice as likely to develop coronary artery disease (CAD) than those with healthy gums (4).
Meanwhile, a 2020 European Journal of Preventive Cardiology report found that poor oral health was associated with an increased risk of cardiovascular disease, particularly among those with gum disease (5).
Professor Sorsa stresses that periodontal disease prevention is vital to maintaining a patient’s oral and overall health.
– Untreated periodontitis leads to low-grade inflammation that affects the whole body, contributing to conditions like cardiovascular disease, diabetes, Alzheimer's disease, and potentially even cancer.
Periodontitis revealed in minutes
According to Professor Sorsa, in the long term, the prevention and rapid diagnosis of periodontal disease benefit the patient, public health, and the economy. This is also possible with the new modern diagnostic and treatment methods available that are revolutionising the whole field of dentistry.
Professor Sorsa’s extensive research career has long focused on developing an immunological rapid test for active matrix metalloproteinase-8 (aMMP-8). The quick test can detect whether a person’s gum tissue is undergoing periodontal breakdown before it is visually apparent.
The test can be performed by a healthcare professional or the consumer independently at home – similar to the COVID-19 antigen test or the traditional rapid pregnancy test (6).
–The aMMP-8 rapid test can measure and assess active periodontal adhesive tissue loss and the risk of its progression within five minutes in the dental chair non-invasively, i.e. without disturbing the tissue under examination. The test complements the diagnosis, follow-up, and maintenance treatment of periodontitis and peri-implantitis, says Professor Sorsa.
When discussing new treatment methods and prevention of periodontitis, he highlights Lumoral therapy. He calls Lumoral a drug-free alternative for treating and preventing severe gum disease.
– Lumoral enhances the effect of the toothbrush, and studies show that it also significantly improves the results of professional oral care. At the same time, the device can potentially reduce the need to use drugs traditionally used to treat gum disease, such as antibiotics and chlorhexidine.
Based on photodynamic therapy, a light-activated antibacterial effect, Lumoral slows down plaque formation and significantly reduces the burden of harmful bacteria in the mouth. The product’s user profile is suitable for all ages, but it is particularly recommended for those with a history of problems with common oral diseases, tooth decay, and gum disease (2).
