This study is one of the first to identify epigenetic markers in oral cancer. Identifying these markers could help detect early signs of cancer and significantly improve patient survival rates. The study was conducted by researchers from the University of Otago in New Zealand and the Indian Statistical Institute (ISI) in Kolkata. The research team recruited 16 oral cancer patients in India who either smoked or chewed tobacco or had mixed habits, and took samples of their tumours and adjacent tissue. After isolating the DNA in the samples, the researchers discovered regions with altered epigenetic profiles in tumour cells compared with adjacent cells. in oral cancer, using cutting-edge approaches,” said co-author Dr Aniruddha Chatterjee, Senior Research Fellow and Rutherford Discovery Fellow in the Department of Pathology at the Dunedin School of Medicine at the University of Otago. The findings showed that the arrangement of a certain epigenetic mechanism, called DNA methylation, might be responsible for dictating gene expression and the spread of abnormal cells. “By validating in a larger cancer cohort, we have shown that a subset of these biomarkers is significantly associated with poor prognosis of patients,” Chatterjee said. The findings of a new study could help decrease high oral cancer mortality in developing countries. (Photograph: Matej Kastelic/Shutterstock) Epigenetics can alter gene expression in cancer cells without changes to the DNA sequence and can cause tumour progression. “This phenomenon is relatively new and understudied, particularly in oral cancer. This study is one of the first to identify epigenetic markers The age-adjusted incidence of oral cancer in the world is estimated at four cases per 100,000 people, according to the World Health Organization. This oral disease is more common in men and in older people, and varies considerably by socio-economic condition. According to the 2019 report of “India Against Cancer”, of the 300,000 cases of tobacco-associated oral cancer detected globally, 86 per cent are from India. Additionally, late diagnosis and poor prognosis are key problems associated with the high mortality rate of this cancer in developing countries. The research group was surprised to find such broad differences in the oral cancer tissue compared with adjacent healthy tissue in the same patients. “We were also surprised to see that small molecules, called microRNA, were methylated or demethylated in the tumours from smokers or chewers or mixed habits, suggesting that therapeutic intervention might be different in patients depending on the way the tobacco was abused,” said lead author Dr Roshni Roy, professor in the Department of Pathology at the University of Otago.

(Photograph: morisfoto/Shutterstock) CHEONGJU, South Korea: South Korea’s Ministry of Food and Drug Safety has issued a re-approval of the health claim that consumers from 3 to 80 years old of the sweetener XIVIA Xylitol have a reduced risk of dental caries. The manufacturer, DuPont Nutrition & Health, is the first company in the country to receive such re-approval. In the re-evaluation of the sweetener, the ministry reviewed 146 research reports, including 94 clinical trials, and concluded that XIVIA Xylitol helps reduce the risk of caries XIVIA Xylitol is claimed to deliver sweetness at 50 per cent of the calorie level of sugar. In addition, it is preferred for its relatively low glycaemic index, which makes it suitable for diabetic and health-conscious consumers. In addition to replacing sugar in chewing gum and other confectionery applications, xylitol is commonly incorporated into oral hygiene products, including toothpaste, mouthwash and teething gels.

According to researchers, the giant panda has particularly resistant tooth enamel, which can recover its structure and geometry to counteract the early stages of damage. Hydration plays a key role in the process. The viscoelasticity of the organic-rich matrix surrounding the mineral prisms and fibres facilitates self-recovery, while the presence of water decreases the width of any cracks that do form, with only a minor cost in terms of hardness. “Our findings identify a novel means by which the tooth enamel of vertebrates develops an exceptional durability to accomplish its functionality,” added Liu. “The self-recovery process represents a new source of durability that differs markedly from the conventional protocol of fracture mechanics.” The team which investigated the tooth structure of the panda was made up of researchers from the Institute of Metal Research of the Chinese Academy of Sciences in Shenyang, the University of Science and Technology of China in Hefei, Lanzhou University of Technology in Lanzhou and the University of California, Berkeley in the US. They believe their observations could be replicated in the tooth enamel of all vertebrates, including humans, and inspire the design of artificial durable ceramics. “Tooth enamel possesses an exceptional durability and plays a critical role in the function of teeth, however, [it] exhibits a remarkably low resistance to the initiation of large-scale cracks comparable to geological minerals,” said Prof. Robert O. Ritchie, who led the study. The ingenious design of the panda’s tooth enamel, which has to withstand a daily diet of bamboo—a ma- Scientists from China and the US have discovered that hydration is the key to pandas’ teeth lasting a lifetime.

When there is an impact on the enamel, a variety of different deformation mechanisms take place to mitigate the growth of small cracks and prevent the formation of large cracks. “The tooth enamel is capable of partially recovering its geometry and structure at nano- to micro-scale dimensions autonomously after defor- mation to counteract the early stage of damage,” explained first author Zengqian Liu. “[This] property results from the unique architecture of tooth enamel, specifically the vertical alignment of nanoscale mineral fibres and micro-scale prisms within a water-responsive organic-rich matrix.” As the architecture of the panda’s tooth enamel is essentially similar to that of other vertebrates, the researchers believe that this self-recovery behaviour is likely to occur in tooth enamel in general. “Our findings also offer inspiration for the development of artificial, durable, self-recoverable ceramic materials,” said Ritchie. The team is hoping to develop tooth enamel-inspired self-recoverable durable materials by introducing shape memory polymers at the interface of ceramics. The study, titled “Hydrationinduced nano - to micro -scale self-recovery of the tooth enamel of the giant panda”, was published in the November 2018 issue of Acta Biomaterialia.

Using 3-D imaging of the airways with the patients su- pine to simulate sleeping conditions, the study confirmed that the treatment is effective at opening the airways and warrants further collaboration between dentists and doctors in the treatment of sleep apnoea. The treatment was developed by researchers from the Department of Orthodontics at Hiroshima University Hospital. The participants included eight men and five women who were diagnosed with mild to moderate OSA and under- “This is like when you have to use glasses. You have to wear them every time you want to see properly so [patients] have to wear this appliance every time [they] want to sleep better,” said study co-author Dr Hiroshi Ueda, an associate professor in the Graduate School of Biomedical and Health Sciences at Hiroshima University. Previous research typically measured patients standing up, a technique that does not simulate sleeping conditions. The current study measured the change in airway space of patients lying flat. It demonstrated that the proportional size of the soft-tissue volume, that is, the soft palate and tongue in the oro-hypo- pharyngeal region, significantly decreased when the patient was wearing an MAA. This forward displacement of the soft tissue thereby increased the retro-glossal airway space, except the nasopharynx, three-dimensionally and therefore allowed for easier breathing. According to the researchers, further investigations that focus on 3-D airway enlargement analysis of various sites affected by MAA therapy are required in a larger number of patients with OSA. This would help scientists understand the pathogenesis of OSA and the clinical applicability of MAA fully. The study, titled “Multislice computed tomography assessment of airway patency changes associated with mandibular advancement appliance therapy in supine patients with obstructive sleep apnea”, was published online on 3 March 2019 in Sleep Disorders.[3] => 03 ASIA PACIFIC NEWS Dental Tribune Asia Pacific Edition | 02/2019 State government bans advertising of junk food on publicly owned space By DTI BRISBANE, Australia: An unhealthy diet can be a contributing factor to poor oral and general health, and advertising plays a key role in this regard.

Consequently, various representatives of the health sector are calling for the government to take action. In a recent statement, the New Zealand Dental Association (NZDA) called for better government fund- AD ing to enable low-income adults to access dental care. Even though New Zealand adults have experienced great improvements in oral health since the 1980s, still many patients only visit a dentist when a dental problem occurs, and in particular, low-income adults see the cost as a significant barrier. “Some truly cannot afford care, and for these groups we must do better, and that involves working with government on a better deal,” said Dr Bill O’Connor, President of the NZDA. PRINT EVENTS SERVICES EDUCATION DIGITAL Dental Tribune International The World's Dental Marketplace www.dental-tribune.com The New Zealand Dental Association is urging the government to provide affordable dental care for adults.

A lot of [them] can’t afford dental work so their options are to remain in pain or extract their teeth themselves. The consequences of paying for dental care would be sacrificing food on the table. The government should be looking for more ways to better subsidise dental work so our families don’t have to keep suffering.” According to Dr Sherry Sembhy, from Rotorua Dentists, self-dentistry is dangerous, as people do not know what they are doing, do not understand the anatomy of their teeth and use unsterile tools, which make the condition only worse. Infections, abscesses, swelling and broken teeth and jaws were some of the possible outcomes of the home procedures which Sembhy said could end up costing even more in repairs.[5] => Dental Tribune Asia Pacific Edition | 02/2019 05[6] => 06 REGISTER FOR FREE!

Researchers at the KLE Academy of Higher Education and Research in Belagavi have tested different approaches to oral hygiene training and compared their effectiveness. For the study, 90 visually impaired children between the ages of 12 and 15 were selected and randomly assigned to three equal groups. The first group was trained with verbal and tactile stimuli and playful teaching methods, the second one was trained using braille, while the third group received a combination of these two approaches. corded their knowledge and practice of oral hygiene and their attitude towards it. The researchers found that the combined hygiene training in the third group reduced the children’s plaque and gingival scores by 55 and 52 per cent compared with the other two groups. In addition, not only did the children’s practical implementation improve, but their knowledge of the subject and their attitude towards it did too. The best method of educating visually impaired children on oral health is by using a combination of different stimuli, a study has found. (Photograph: wavebreakmedia/Shutterstock) The researchers tested the dental hygiene of the children by assessing plaque and gingival status at different intervals.

In new research originating from Japan, scientists have developed a cell-based regenerative therapy approach. The proposed therapy design promises to address periodontitis without some of the shortcomings and limitations of regenerative therapies to date. According to the researchers from Tohoku University in Sendai, the therapy will be faster and cheaper. “The use of cell-based therapies is a promising approach to treat human disease. This kind of treatment paradigm is important because commercially available stem cells that represent a cell-based therapy specifically developed to treat periodontal tissue regeneration will reduce time and cost while improving quality assurance,” said lead author Prof. Masahiro Saito, from the Department of Restorative Dentistry at Tohoku University Graduate School of Dentistry. In a new approach to the treatment of periodontitis, the researchers transplanted stem cells from healthy mini pigs to those who had periodontal defects and, by doing so successfully, overcome the shortcomings that can be associated with autologous stem cell treatments. By using this mini pig periodontal Researchers in Japan have developed a new method to treat periodontitis that they believe will be faster, cheaper and more effective than anything available today. (Photograph: Sergii Kuchugurnyi/Shutterstock) defect model, they demonstrated that allogeneic adipose-derived mesenchymal progenitor stem cells (ADMPCs)—mesenchymal stem cells (MSCs) derived from fat tissue—are safe and effective for the treatment of periodontitis. “Our study demonstrates that ADMPCs appear to be safe and not triggering an immune response in allogeneic settings, and as such it explores the potential use of allogeneic MSCs for tissue regeneration. The study is a powerful first step towards further development of stem cellbased therapy for the treatment of periodontal disease,” explained Saito. The study, titled “Periodontal regeneration by allogeneic transplantation of adipose tissue derived multi-lineage progenitor stem cells in vivo”, was published on 29 January 2019 in Scientific Reports. The study was conducted in collaboration with researchers from Osaka University in Osaka and Fujita Health University in Toyoake. Study links frailty to poor oral health By DTI MELBOURNE, Australia/LONDON, UK: It is widely known that poor nutrition is a risk factor for frailty. Similarly, the link between nutrition and oral health status has been estab- lished in numerous studies. New research has bridged the gap between these two relationships, however, and found that poor oral health is independently associated with frailty. The study, conducted by researchers at the Monash Aging Research Centre at Monash University in Melbourne, assessed the oral health, nutrition and frailty of 168 hospitalised geriatric patients over six months using previously validated tools. create a series of challenges for how we care for the population’s oral health,” he said. The results show that elderly people who suffer from frailty are substantially more prone to issues with their oral health. Frailty is linked to a reduced ability to bite and chew food, as well as sensitivity to hot and cold food and drink. The study also revealed that frail adults are more likely to feel self-conscious about their teeth, gingivae or dentures and are less likely to access dental care. “The first problems to occur are often because of a loss of dexterity. Limited mobility, no matter how small, can have an extremely large effect on our ability to care for our own health. In terms of oral health, this means effective toothbrushing becomes much harder. Balanced nutrition also becomes more difficult,” he continued. Previously, experts have identified a relationship between frailty and difficulties with speech and with taking medication for oral pain. Dr Nigel Carter, OBE, Chief Executive of the Oral Health Foundation, a UK-based charity, stated in a press release regarding the study that the oral health of older people remains an ongoing issue. New research shows that elderly people who suffer from frailty are substantially more prone to issues with their oral health.

In turn, it will Carter called on the UK government to provide greater access to dental services for frail adults in hospitals, as well as for those in nursing homes, and to provide better oral health training for carers. “The government must find such proactive solutions if they are to address the health needs of an ageing population,” Car ter stated.

A recent survey, however, has found that there is an entirely different source of stress and anxiety for dental professionals in the UK: the fear of being sued, receiving a claim or complaint, or being the subject of an investigation by the General Dental Council. The survey was conducted by Dental Protection, part of the notfor-profit Medical Protection Society for doctors, dentists and healthcare professionals. It asked more than 1,100 UK-based dentists for feedback regarding the sources of their work-related stress, and 77 per cent responded that the fear of being sued by an unsatisfied patient had caused them to become stressed and anxious. A recent survey of more than 1,100 UK-based dentists found that the fear of being sued by an unsatisfied patient is a primary source of workrelated stress. (Photograph: VHstudio/Shutterstock) The results of the survey come just months after the findings of an analysis published in the British Dental Journal showed that general dental practitioners exhibit the highest levels of stress and burnout among UK dentists. The findings of this research suggested that, while practice ownership could possibly reduce burn-out due to regulatory stress, it does not positively influence patient-led stress for dentists. Remarking upon the findings of the survey, Dr Raj Rattan, MBE, Dental Director at Dental Protection, said: “Stress can impact on a dentist’s health and practice in a number of ways. It can affect confidence, clinical judgement, morale and even lead to performance issues. Research confirms that high stress levels affect performance and increase the potential for adverse outcomes of error. These may in turn spark patient complaints and claims and a self-perpetuating vicious circle is established.” “Modern life is full of challenges, stressors and pressures—and the dental profession is no exception. Dental Protection would like to encourage dentists to seek help and advice to manage the condition be- fore it causes irreversible changes to health and well-being,” he concluded. AD SIGN UP NOW!

This was true for a patient at the Department of Otorhinolaryngology, Head and Neck Surgery of the Aarhus University Hospital. After two years of a stuffy and runny nostril and the loss of his ability to smell, doctors discovered that a retained tooth growing in his nasal cavity was the reason for his symptoms. A CT scan of the 59-year-old patient revealed a mucus-covered mass on the floor of his nasal cavity. As a result, the doctors suspected that the patient had either a dermoid cyst—a growth that some people are born with that contains structures such as hair, teeth, fluid or skin glands—or an impacted tooth. The medical team decided to use an endoscope to perform a surgical extraction. The examination of the extracted mass revealed the retained tooth, which was covered with inflamed nasal tissue. Usually, a condition like this is caused by trauma, infections from a cyst, or developmental disturbances such as cleft lip or cleft palate, but the doctors had no obvious explanation for this particular case, as stated in their report. “Our patient most likely had the intranasal retained tooth most of his life, but had late onset of symptoms,” stated co-author Dr Milos Fuglsang, who had carried out the tooth extraction. According to the BMJ, only 23 patients have been identified as experiencing similar incidents over a period from 1959 to 2008. It is most common in males and more common among adults than children. For Fuglsang, this was the first case of its kind in his medical career. The case report, titled “Retained tooth in the nasal cavity: A rare cause of nasal congestion”, was published on 21 February 2019 in BMJ Case Reports. The retained tooth shortly after it was removed from the patient’s nose.

As a solution, South-Korean Samsung spin-off Kitten Planet has launched Brush Monster, a fun and interactive mobile app game that teaches children healthy brushing habits and enables parents to analyse the brushing data afterwards. Via augmented reality and an innovative smart brush, the app walks kids through the brushing process from start to finish in real time, while turning good oral hygiene into an engaging game. Prevention spoke to Dr Jongho Choi, Brush Monster cofounder and CEO of Kitten Planet. Tube, and teachers and parents often spend many hours explaining to children how to brush well. But these methods are all indirect— learning and doing are separated. Because children easily forget what they have learnt and still end up brushing the wrong way, these methods often fail. With Brush Monster, we put the focus on learning by doing. Through augmented reality, the screen of the smartphone or tablet acts like a magical, interactive bathroom mirror: children can see their own faces, and the animations show them where and how to brush. This corresponds to the views held in paediatric dentistry, namely that children should watch themselves in the mirror while brushing and get feedback at the same time. However, bathroom mirrors are often too high for small children, and the instructions are not always correct. This is where Brush Monster comes in. Dr Choi, where did the idea for Brush Monster come from? The other co-founders and I are all fathers of young children, and we all at one point or another experienced for ourselves that it can be quite difficult to get kids to brush their teeth, let alone to do so properly! Also, sometimes kids say they have brushed their teeth well, but it is difficult for parents to know if this is true. How can parents be sure that their children have brushed well? Among the main problems when leaving toothbrushing up to young children are that they rarely brush for longer than one minute straight and often brush less than twice per day. Many children also only brush the buccal surfaces of the teeth. The built-in sensor in our smart toothbrush divides the mouth into 16 regions, and through 3-D motion analysis, the smart brush tracks and analyses how well each of these 16 regions was brushed, and parents get a full dental report after brushing. All of the Kitten Planet co-founders are engineers in the healthcare industry, and we’re all big on prevention, so we tried to find a fun, new solution for these problems, something that children can put into practice and that is very present in their everyday lives. Brush Monster not only introduces a great toothbrush and a fun game that teaches kids healthy brushing habits and allows parents to analyse the process, but also helps children learn to be confident doing something independently at an extremely important stage in their development. Lastly, Brush Monster is a solution for the typical struggle many parents have in getting their children to brush their teeth and makes bedtime more relaxed. What is the in-game story around Brush Monster? How does the game work? Well, first of all, Brush Monster is supported by almost all phones and tablets and is currently available in 137 countries. People can easily download the app from Google Play and the App Store, and then kids can get started with brushing right away. The app has a classic villain versus superhero storyline. The game starts with the evil character—Green Mold— capturing the friendly Brush Monsters. By following detailed instructions on where, when and how to brush their teeth, kids can save the Brush Monsters and collect items and stickers. Sparkles and crazy goggles appear on the children’s faces while brushing, and the monsters change regularly to With Brush Monster, Dr Jongho Choi and the other Kitten Planet cofounders have launched an interactive mobile app game that teaches children healthy brushing habits.

At the end of a successful brushing session, children are rewarded with a star and given the opportunity to take a selfie. routine and technique are instilled in children when they are still young. As such, Brush Monster is aimed at children aged 3–10 and their parents. What age group can benefit from the app? There are many children who hate brushing their teeth or who are not very good at it. According to a study we did, the spatial recognition and motor skills required for good brushing are not fully developed in children younger than 10. Still, brushing is a necessary routine for healthy teeth and a healthy life in general, and the best-case scenario is when a good oral hygiene What difference does the app offer compared with other teaching methods out there? Brush Monster teaches children directly. There is so much educational content aimed at kids already, such as posters at the basins of kindergartens and elementary schools that show children how to brush their teeth in different steps. Children can watch an unlimited number of instructional videos with their favourite characters on You- Brush Monster uses a sonic brush with soft bristles. Yes. The gingivae of small children are relatively soft and weaker than those of adults, so we opted for sonic brushes, as they are effective and gentle. Our smart brush head is designed to guarantee the most effective plaque removal, while five levels of sonic vibration ensure the most effective plaque removal and massage the gingivae. How has the response been so far? We launched the app in January 2018, and it is now the most popular of about 200 brushing apps. Brush Monster currently has a rating of 4.8 and has received so many great responses and user requests for new functions. We are also very happy to see that many parents are now recommending the app to other parents. One Korean online marketing platform even voted the Brush Monster toothbrush the number one electric toothbrush for kids. Most importantly though, parents tell us that their children are now brushing correctly and independently, and actually brush correctly for three minutes.
