Taking control of troublesome tartar

Taking control of troublesome tartar

Tartar is mineralised plaque that forms on the surface of the teeth, usually as a result of poor oral hygiene. Plaque is made up of bacteria, food debris and saliva proteins. If plaque is not regularly removed by brushing and cleaning between teeth, it can harden and become tartar. Tartar is rough and can cause gum irritation, lead to gingivitis and contribute to the development of other oral health problems, such as periodontitis.

How common is tartar buildup?

Tartar is a very common oral health problem. Almost all adults have tartar buildup at some point in their lives, and the incidence increases with age. Here are some important facts to help you understand how common tartar is:

Adults: Most adults will get tartar at some point. The risk increases with age as plaque builds up over time, and possibly oral hygiene can also deteriorate, for example as fine motor skills in the hands deteriorate.

Adolescents and children: Although tartar is more common in adults, it can also occur in adolescents and children, especially if oral hygiene is poor.

Risk groups: Certain groups of people are more prone to developing tartar. These include smokers, diabetics, people with dry mouth, and people with certain types of eating habits (e.g. high consumption of sugary and starchy foods).

Tooth location: Plaque is usually more likely to form on the mandibular incisors and maxillary molars, as the salivary glands are located close to these teeth and saliva can contribute to plaque mineralisation.

How can I prevent the formation of tartar?

Regular and careful oral hygiene is the best way to prevent tartar. Tartar cannot be completely prevented, but the amount and effects can be significantly reduced through good daily oral hygiene and professional cleanings.

Regular brushing: brush your teeth twice a day for at least two minutes at a time with a fluoride toothpaste. Use a soft toothbrush and brush thoroughly on all tooth surfaces, including the gum line.

Use a floss, brush or other interdental cleaning tool daily to remove plaque between teeth where the toothbrush cannot reach.

Healthy diet: avoid sugary and starchy foods and drinks that contribute to plaque formation. Eat healthy foods, such as fruit and vegetables, that promote saliva production and help keep your mouth clean.

Regular dental visits: go to your dentist regularly for check-ups and cleanings. A dental hygienist can remove tartar that you cannot remove yourself at home.

Complementary treatment: regular use of the Lumoral antibacterial treatment reduces the amount of bacteria in your mouth and helps prevent plaque and tartar build-up.

Why do you need to remove tartar?

‘When the tooth surface is rough due to tartar, it is easy for new bacteria to accumulate on the surfaces of the teeth. These bacteria, together with tartar, irritate the gums and cause gingivitis. You cannot remove tartar yourself at home, but dentists and dental hygienists give patients an anti-infective treatment to remove tartar and reduce the amount of bacteria in the gum pocket.’ Viivi Soikkeli, dental hygienist at Hampaasi Dental Clinic in Helsinki, Finland, explains.

Lumoral antibacterial treatment is used as a complement to mechanical tooth cleaning.

‘Lumoral treatment is based on the fact that it effectively reduces the amount of plaque in the mouth, while also reducing the build-up of plaque and tartar,’ says Soikkeli.

Studies have shown that regular antibacterial treatment as an adjunct to conventional non-surgical standard treatment reduces gum inflammation and improves oral hygiene and the healing of deep pockets in chronic periodontitis compared to conventional treatment.

Antibacterial treatment has also been shown to prevent and help reduce inflammation in the tissues surrounding implants. It is suitable for everyone, but light-activated antibacterial treatment is considered most effective for patients who need to improve their oral hygiene.

Unlike conventional antibacterial mouthwashes, which affect the whole mouth and also remove the good bacteria that we need, Lumoral treatment targets only plaque, reducing bacterial and tartar build-up.

‘I recommend Lumoral especially to customers who have a lot of tartar,’ says Soikkeli.



Oral Health and Brain Health: The Crucial Connection for Overall Well-being

Oral Health and Brain Health: The Crucial Connection for Overall Well-being

Dental and oral bacteria have been linked to numerous chronic diseases throughout the body. Recent research indicates that thorough brushing and regular dental visits can also play a role in preventing strokes (1).

According to statistics from the World Stroke Organization (WSO), over 13 million people globally suffer from strokes each year, with one in four individuals experiencing a stroke in their lifetime. Surprisingly, up to 90% of these cases could be prevented through lifestyle changes such as adopting a healthier diet, increasing regular exercise, quitting smoking, and even improving oral hygiene practices (2).

In his recent doctoral dissertation in forensic medicine at the University of Tampere, Medical Licentiate Olli Patrakka examined the significance of oral bacteria, particularly viridans group streptococci, in stroke development. While these bacteria are normal mouth microbes, they can lead to serious illnesses like heart valve inflammation when entering the bloodstream, such as through inflamed gums during teeth brushing. (3).

Olli Patrakka suggests that these bacteria, attaching to tooth surfaces and initiating plaque formation, may similarly contribute to stroke and atherosclerosis development when entering arterial walls via the bloodstream during dental procedures or infections.

Poor oral hygiene is a risk factor for strokes

According to Patrakka, dental bacteria are present in the blood clots of stroke patients in about four out of five cases, with similar results yet to be reported. Blood clots were collected from stroke patients undergoing acute care in Tampere, Finland, for the study, along with samples from patients with symptomatic carotid artery stenosis used as endarterectomy tissues. (3).

Epidemiological studies have identified poor oral hygiene as an independent risk factor for strokes. Patrakka suggests that the inflammatory reaction induced by dental bacteria in atherosclerotic plaques could explicitly explain this connection.

The dissertation's findings are significant as they present new opportunities for stroke patient treatment development, Patrakka says. He also believes that the development of a vaccine may also be now feasible.

Patrakka stresses that while further research is necessary to establish causality, the study supports the importance of oral health, particularly in individuals at risk of srokes. He emphasizes that considering the inflammation caused by streptococcal bacteria in the mouth is crucial in stroke prevention as part of routine dental care. Moreover, investigating the potential benefits of timely antimicrobial treatment or bacterial vaccines in the future is essential.

Periodontitis is the root cause of many ailments

Studies show dental plaque bacteria are responsible for about 95 per cent of oral diseases. One of the most common oral diseases is periodontitis, a severe gum disease caused by dental plaque. Early signs of this disease include red gums, gum bleeding, and bad breath. (4)

In patients with periodontitis, the fibres that attach the tooth to the gum are destroyed, forming a periodontal pocket between the gum and the tooth. This pocket may expand around the entire tooth. If the infection is not treated promptly and oral hygiene is not improved, it can progress to destroy more extensively the supporting tissues of the teeth and, ultimately, the jawbone. (4)

Thorough oral hygiene is crucial for the prevention and treatment of oral infections. According to the Oral Health Foundation one-in-four (26%) British adults regularly brush their teeth only once a day raising concerns about the number of people willing to skip twice-daily brushing. (5)

The charity is especially worried by the number of people who regularly fail to brush their teeth last thing at night, when the health of the mouth is most likely to deteriorate.  Insights from the research show that one-in-four (25%) do not brush their teeth in the evening before they go to bed. (5).

Deficiencies in oral hygiene are directly reflected in the statistics of oral infectious diseases. More than 45% of adults in the UK are currently being affected by gum disease. Meanwhile, 10% are living with the most severe form, which can lead to tooth loss. (6)

Thorough mechanical brushing of teeth and cleaning of the interdental spaces are crucial because even asymptomatic oral inflammations can affect the body's overall health. According to statistics, individuals with healthy mouths even live longer, research shows (7).

– Every missing tooth reduces life expectancy. This is talked about far too little, says Tommi Pätilä, a heart and transplant surgeon at HUS New Children's Hospital in Helsinki, Finland.

Pätilä is also one of the developers of the antibacterial Lumoral method. Lumoral is a medical device designed to improve oral hygiene and oral health. The antibacterial oral care method is especially suitable for patients with difficult-to-treat gum diseases such as periodontitis who do not get adequate results from traditional oral hygiene methods such as brushing teeth and cleaning interdental spaces. (8, 9, 10).

The effectiveness of the novel oral health enhancing device relies on antimicrobial photodynamic therapy (aPDT), also referred to as photoantimicrobial chemotherapy. While this technology is already prevalent in dental clinics, the advent of a home-use device allows for more frequent application of this antibacterial treatment. (11)

aPDT technology itself utilizes light energy and a photosensitizer to generate an antimicrobial effect that eliminates problem-causing plaque bacteria from the mouth. Due to its targeted approach aPDT does not lead to bacterial resistance. (11)

The importance of interdisciplinary collaboration

According to Pätilä, the recent medical dissertation at the University of Tampere holds significance as it integrates oral health into overall body health. Enhancing collaboration between doctors and dentists is crucial and needs improvement across various European countries. While many medical doctors already evaluate their patients' oral health at clinics and refer them for additional treatment when needed, closer collaboration is essential.

Diabetes serves as a prime example of a disease where the importance of underlying inflammations is widely acknowledged. However, heightened collaboration is necessary to accelerate diagnoses and even prevent several common diseases.

Olli Patrakka's interest in oral bacteria stemmed from his responsibilities as a pathologist. Has the interest of young doctors in the impact of dental infections on general health increased?

– It hasn't increased significantly, but it should. In my basic medical training about five years ago, there was minimal discussion of the impact of dental infections on overall health. While the topic is relatively new, it's crucial that awareness and scientific evidence grow over time.

Patrakka underscores the importance of general practitioners recognizing when a dental issue necessitates a referral to a dentist. This could streamline the treatment of oral infections and potentially aid in achieving a balance in treating various general diseases.

– My research contributes to the growing evidence that oral health significantly influences overall health. The blood vessels of the tooth pulp directly connect to the systemic circulation. Therefore, if teeth are in poor condition, bacteria and their byproducts can circulate directly into our bodies.

Koite Health Collaborates with Innodent Trading: Revolutionizing Dental Care in Thailand with its Lumoral Technology

Koite Health Collaborates with Innodent Trading: Revolutionizing Dental Care in Thailand with its Lumoral Technology

In the field of dental care, changes are constant as fresh ideas shape the industry. A recent collaboration agreement between Finland’s Koite Health Ltd and Trading Co., Ltd. from Thailand is set to revolutionize dental care standards by introducing innovative light-activated technology to the country.

Founded in 2017, Innodent has been at the forefront of delivering cutting-edge dental solutions to Thailand's healthcare sector. Driven by a commitment to leverage the latest advancements in high-tech solutions, the company aims to provide the most innovative technologies to the dental industry. This strategic vision led to a partnership with Koite Health, and the introduction of Lumoral, a Finnish med-tech innovation, to the dental market in Thailand.

– The introduction of Lumoral to Innodent's product portfolio was the result of a personal recommendation from Dr. Hildebrand, a renowned maxillofacial surgeon from Berlin. Dr. Hildebrand's successful clinical experiences with Lumoral convinced the team at Innodent to explore this revolutionary technology further, explains Thomas Constantin, CEO and owner of Innodent Trading Co., Ltd.

Lumoral: an innovative personal healthcare device

So, what exactly is Lumoral, and how does it work? Mr. Constantin reminds that the close link between oral bacteria and overall health and well-being is an important factor that sparked interest in the Finnish oral health-enhancing innovation in the first place.

– Oral bacteria can cause dental caries and bad breath but there can also be more severe secondary effects such as cardiovascular diseases, dementia, psoriasis and many more. Overall health starts with a healthy mouth. It is therefore important to regularly clean the mouth thoroughly.

Lumoral is an innovative personal healthcare device designed to remove 99.9% of harmful oral bacteria while preserving the healthy mouth flora. Traditional oral hygiene methods can only remove approximately 60% of bacteria, leaving behind a significant risk of oral health issues, Thomas explains.

Lumoral's advanced technology utilizes color molecules in its Lumorinse mouth rinse, which adhere to harmful oral bacteria attached to teeth surfaces and gum tissue in the mouth. Subsequently, the light emitted by the mouthpiece reacts with the green sensitizer, effectively breaking down the cell membrane of bacteria and destroying them both from inside and outside. This method ensures the eradication of harmful bacteria without the risk of resistance development.

Long-term benefits for implant patients

The addition of Lumoral to Innodent's product portfolio aligns with the company’s focus on dental implantology, with a specialization in ceramic implants. While the industry predominantly utilizes titanium implants, scientific evidence suggests a significant risk of peri-implantitis, an inflammation of the tissues surrounding these metal implants, over time.

– Lumoral presents a solution to mitigate this risk, offering long-term benefits for implant patients, Constantin says.

Furthermore, Lumoral's versatility extends beyond implant care, offering benefits for individuals with various oral health concerns, including chronic bad breath, gum disease, and orthodontic patients wearing braces or clear aligners.

– This accessibility makes Lumoral an invaluable addition to Innodent's offerings, catering to a diverse range of dental needs in Thailand.

– The great advantage of Lumoral however, is that everyone benefits from removing harmful oral bacteria. Whether you are wearing braces or clear aligners, suffer from chronic bad breath, gum disease or simply want to have a perfectly clean and healthy mouth, Lumoral is your solution.

Promising prospects for both companies

The collaboration between Koite Health and Innodent holds promising prospects for both companies and dental patients in Thailand. Mr. Constantin says that for Innodent, this partnership marks a significant expansion into the business-to-consumer (B2C) market, enabling the company to reach individual consumers through online channels like their dedicated webshop.

– This shift opens new avenues for marketing and sales, enhancing accessibility to innovative dental solutions for patients across the country. Ultimately, the collaboration aims to raise awareness about oral health and its crucial role in overall well-being among the Thai population.

– By introducing Lumoral's advanced technology to the market, Koite Health and Innodent are paving the way for a new era of dental care in Thailand, one that prioritizes prevention, innovation, and improved patient outcomes.
