Although mas- ticatory and swallowing functions are closely linked to overall health, nutritional status and quality of life, chemical agents used to treat dry mouth may cause side effects and often require a prescription. In a new study, researchers have im- proved oral function in the elderly by performing a simple oral stretch- ing and exercise technique. According to the researchers, conventional oral exercises per- formed in previous studies were impractical for continuous use in the elderly owing to the extended Researchers have developed a 2-minute-long simple oral exercise that improved mastication, salivation and swallowing function in the elderly people in their study. (Photograph: Photographee.eu/Shutterstock) Food additive used in toothpaste and chewing gum may have negative impact on health duration needed for positive treat- ment outcomes. The present study used a simple oral exercise (SOE-, which included lip stretching, tongue stretching, cheek stretching, mas- ticatory muscle exercise and swal- lowing movements to reduce per- formance time and to determine the short-term effects of the SOE. In the course of the study, 84 participants aged 65 years and older performed the SOE twice a day for one week after receiving instructions from a trained dental hygienist. The researchers evaluated the partici- pants’ masticatory performance by using the mixing ability index (MAI-. Additionally, they assessed the un- stimulated saliva and the moisture levels of the tongue and buccal mu- cosa and performed the repetitive saliva swallowing test. On the basis of each of these four measurements, participants were dichotomised into two groups with good and poor oral health conditions. The data showed that the mean MAI increased by 6 per cent imme- diately after the intervention and by 16 per cent in the poor-chewing group. Similarly, the amount of un- stimulated saliva increased by 0.1 ml/min immediately after the SOE and by 29 per cent in the poor-salivation group. The degree of tongue moisture increased by 3 per cent and was maintained, ac- cording to the researchers. In the poor-swallowing group, 25 per cent and 40 per cent of the participants were upgraded to the good-swal- lowing group immediately after the intervention, as well as after one week of intervention, respec- tively. Finally, the participants ex- perienced less discomfort as their oral function improved. The study, titled “Improvements in oral functions of elderly after simple oral exercise”, was published online on 16 May 2019 in Clinical Interventions in Aging. AD By DTI SYDNEY, Australia: Nanoparticles of the common food additive titanium dioxide (E171-, which is found in more than 900 food products, in- cluding chewing gum, as well as in some medicines and toothpastes, may have a negative impact on human health, according to a re- cent study. The results of the study have prompted experts to call for better regulations and more dis- cussion around the topic of food additives. Conducted by researchers from the University of Sydney, the study showed that E171 has an impact on gut microbiota and impairs some of its functions. This could cause inflammatory bowel diseases or colorectal cancer. Co-lead author Dr Wojciech Chrzanowski, an asso- ciate professor at the University of Sydney Nano Institute, said: “There is increasing evidence that contin- uous exposure to nanoparticles has an impact on gut microbiota com- position, and since gut microbiota is a gatekeeper of our health, any changes to its function have an in- fluence on overall health.” In 2017, French environmental association Agir pour l’Environne- ment studied the composition of 408 toothpastes and found E171 in 271 dental pastes, 25 bio-toothpastes and 29 toothpastes for children. Now, after ANSES, the French agency for food, environmental and occu- pational health and safety, released an analysis of 25 new studies on E171’s toxicity, concluding there was a lack of scientific data on its harm- fulness but recommending the use of known alternatives, the French government plans to ban the use of the additive altogether from 2020. According to the authors of the Australian study, increasing rates of dementia, autoimmune diseases, cancer metastasis, eczema, asthma and autism are among a growing list of diseases that have been linked to soaring exposure to E171 nanopar- ticles. Speaking about the results and what it means for the Austra- lian government, the researchers said that E171 consumption should be better regulated by food au- thorities. The study, titled “Impact of the food additive titanium dioxide (E171- on gut microbiota–host in- teraction”, was published on 14 May 2019 in Frontiers in Nutrition. Distinguished by innovation A new Australian study has found that nanoparticles of the food additive titanium dioxide, which is found in products such as toothpaste and chewing gum, may have a negative impact on human health.

02 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 03/2019 Review links protruding teeth to long-term oral health risks By DTI ADELAIDE, Australia: A new system- atic review has reported that chil- dren with protruding primary or early permanent teeth have an in- creased chance of damaging them. However, the researchers affirmed that the oral health risks linked to protruding teeth can be signifi- cantly reduced without entailing prohibitive costs. The review, undertaken at the University of Adelaide, included 41 studies and more than 50,000 children aged under 19 years and confirmed a direct link between the degree to which a young pa- tient’s teeth protrude and the prob- a b i l i t y o f d a m a g i n g t h e m . “Traumatic dental injuries have been identified as the fifth most prevalent disease or injury glob- ally and their subsequent manage- ment is costly,” said Dr Esma Dog˘ramacı, lecturer in orthodon- tics in the Faculty of Health and Medical Sciences at the University of Adelaide Dental School. “While the number of traumatic dental injuries have fallen over recent de- cades, they have significant phys- ical, psychological and economic consequences,” she added. “Young children up to the age of 6 years with teeth that stick out more than 3 mm have over three times higher chance of trauma than children without protruding teeth. Children over 6 years with teeth that pro- trude more than 5 mm have over double the chance of trauma.” According to Dog˘ramacı, cor- rective orthodontic treatment of children’s teeth is not usually un- dertaken until all permanent teeth have erupted, usually after the age AD Researchers have recently established in a systematic review that children with teeth that protrude more than 3 mm have more than double the chance of dental trauma. (Photograph: Evgeniy Kalinovskiy/Shutterstock) of 12 years. However, an expensive visit to an orthodontist is not es- sential to protect protruding teeth, she said. “A dentist can easily mea- sure how far a child’s teeth stick out and recommend whether they should be fitted with a brace. They can apply simple braces which can reduce the prominence of protrud- ing teeth and significantly reduce the chance of them being damaged,” explained Dog˘ramacı. In order to protect protruding teeth from damage, Dog˘ramacı recommends discouraging chil- dren from sucking their thumb and suggests they wear a mouth guard. “Early identification and protection of protruding teeth through regular dental check-ups reduces the chance of early prob- lems becoming long-term dental issues,” she commented. “If young teeth are broken or knocked out, long-term issues may occur, like the need for root canal treatment or even tooth loss, requiring a life- time commitment for general den- tal treatment.” “Also, if orthodontic treatment is carried out on teeth that have previously suffered from trauma, further complications can occur during orthodontics that could lead to the loss of those teeth,” she added. “The results of this study confirm that regular check-ups, particularly for children, are a must for good long-term dental health.” The study, titled “The association of overjet size and traumatic den- tal injuries—A systematic review and meta-analysis”, was published online on 6 May 2019 in Dental Traumatology, ahead of inclusion in an issue.

Dental Tribune Asia Paciﬁc Edition | 03/2019 ASIA PACIFIC NEWS 03 Study finds genetic make-up has little impact on oral health By DTI MELBOURNE, Australia: The idea that oral health comes down to genetics can be a damaging one. According to authors of a recent study, which followed the oral health of twins from birth to age 6, there is no link, and the idea that there is can prevent people from changing their damaging oral health habits. Led by Dr Mihiri Silva from the Murdoch Children’s Research In- stitute, the study followed 173 sets of twins, identical and non-iden- tical. “How genetics impacts on dental health has not often been studied. This is the first twin study that looks at both genetics and early life risk factors, such as ill- ness and lifestyle.” A new study has shown child oral health to be related to lack of fluoride, the mother’s health during pregnancy and other factors, but not genetics. (Photograph: Fab_1/ Shutterstock) According to Silva, the study’s results found that identical twins— with identical genomes—had vary- ing degrees of dental caries. “This means that environmental factors, like a lack of fluoride in water, seem to be the prime cause of cav- ities not genetic make-up,” she explained. Despite genetics not playing a role in oral health, the study did reveal a link between the mother’s health and lifestyle during preg- nancy and the child’s future dental health, with obesity in pregnancy a definite marker for increased risk of childhood caries. “Perhaps the mother’s weight has a biological influence on the developing foetus or perhaps the risk of decay rises because of increased sugar con- sumption in that household,” hy- pothesised Silva. Another concerning result to come out of the study was the es- timation that one in three Austra- lian children have caries by the time they start school. With the 2011 Vic- torian Department of Health and Human Services statistics showing that more than 26,000 Australians under the age of 15 are admitted to hospital to treat caries every year, the estimation may not be too far off. “Our findings also reinforce how important it is for paediatri- cians and other health profes- sionals to educate children to start preventive measures early in life, prior to the onset of dam- age to dental tissues,” concluded Silva. The study, titled “Genetic and early- life environmental influences on dental caries risk: A twin study”, was published in the May 2019 issue of Pediatrics.

04 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 03/2019 Fluoride reduces dental risk from minimal and extended breastfeeding, study says By DTI ADELAIDE, Australia: A recent study has examined the interaction be- tween fluoridated water consump- tion and breastfeeding duration in relation to dental caries expe- rience. The findings suggest that exposing children to fluoridated water may reduce the risk of den- tal caries. According to a report published in the Oral health and dental care in Australia: key facts and figures, AD SIGN UP NOW! The world's dental e-newsletter A new study has reported dental and general health benefits of breastfeeding and water fluoridation. (Photograph: Evgeny Atamanenko/Shutterstock) in 2010, 55 per cent of 6-year-olds had experienced dental caries in their primary teeth. The new re- search looked at dental caries in 5- and 6-year-olds in Australia and examined whether they had been exposed to fluoridated water or breastfed as infants and for what duration. The study used data col- lected in one of the largest and most comprehensive population-based studies of child oral health in Aus- tralia, the National Child Oral Health Study 2012–14. The findings indicated that breastfeeding for over a month and up to 24 months was associated with good oral health. Minimal breast- feeding, which includes no breast- feeding or breastfeeding for less than one month, however, and extended breastfeeding beyond 24 months were both linked to increased den- tal cavities. However, these effects were lessened if children were ex- posed to fluoridated water. “Breastfeeding is important not only for general health but also for the dental health of young chil- dren,” said senior author Dr Loc Giang Do, a professor in the Faculty of Health and Medical Science at the University of Adelaide’s Austra- lian Research Centre for Population Oral Health. “Minimal breastfeed- ing can increase risk for having dental decay in children, as can sustained breastfeeding beyond 24 months,” he added. “However, po- tential risk can be reduced by drink- ing fluoridated water in formula or ensuring that breastfed children are given fluoridated water to drink after the age of 6 months.” According to Do, in fluoridated areas, breastfeeding can be recom- mended beyond the age of 24 months, while in non-fluoridated areas, breast- feeding for up to 24 months is rec- ommended not only for child gen- eral health and development but also for child dental health. “The use of fluoridated tap water should be recommended for young children,” Do commented and added that the dental profession should support and even encourage mothers of in- fants to breastfeed.

06 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 03/2019 CPAG calls for free dental care and healthcare for all youth By DTI AUCKLAND, New Zealand: Early child- hood dental caries is the most com- mon chronic disease seen in children and a leading cause of hospital ad- missions for New Zealand children. The Child Poverty Action Group (CPAG- is attempting to tackle the issue by calling for free universal healthcare, including dentistry, pre- scriptions and specialist hearing and vision care, for all children and ado- lescents younger than 18 years of age. AD PRINT EVENTS EDUCATION DIGITAL SERVICES Dental Tribune International The World's Dental Marketplace www.dental-tribune.com In the group’s submission to the New Zealand Health and Disability System Review, CPAG stated that universal healthcare for children should begin before they are born and should include free general practitioner (GP- visits and preg- nancy-related dental care for ex- pectant mothers. The group is also asking for more school-based ini- tiatives and has urged the govern- ment to expand health and mental health services, to appoint more school social workers, to provide school lunches and to tax sug- ar-sweetened beverages. In a recent submission, the Child Poverty Action Group has recommended taking immediate steps to achieve free dental care and healthcare for all young people under 18 years. (Photograph: pikselstock/Shutterstock) “Research shows that adoles- cence is one of two periods that are critically important for social and physical development, the other being preconception to 3 years of age,” said paediatrician and CPAG children’s health spokesperson Prof. Innes Asher. “It is vital that all our teenagers can easily access appro- priate and timely primary health- care. Their health and futures should not have to rely on their families’ ability to afford healthcare, as is currently the case.” According to the group, chil- dren living in poverty are at a higher risk of falling ill and dying compared with other children. That is why CPAG’s recommendations are designed to help achieve not only healthcare access equity but also health equity for all young people. “Primary care and public health is where our focus needs to start. Significant long-standing underfunding in these areas is one reason that too many of our chil- dren are ending up hospitalised unnecessarily,” said CPAG public health spokesperson Dr Nikki Turner, an associate professor and Director of the Immunisation Ad- visory Centre at the University of Auckland. Currently, free GP visits in New Zealand are available to children aged 13 and under. Pregnant women are entitled to free maternity ser- vices but not to free GP visits or pregnancy-related dental care.
Dental Tribune Asia Paciﬁc Edition | 03/2019 ASIA PACIFIC NEWS 07 Eating disorders—Oral health professionals have role in early identification By DTI SYDNEY, Australia: Eating disorders and disordered eating together are estimated to affect over 16 per cent of the Australian population, ac- cording to the National Eating Dis- orders Collaboration (NEDC-. The Australian Dental Association (ADA- and the NEDC have collaborated in order to spread awareness about eating disorders and their identifi- cation and assessment and to en- courage referral among oral health professionals. Early intervention is critical for a patient with an eating disorder. The sooner treatment occurs, the better chance the individual has of recov- ery. Consequently, the oral health practitioner is uniquely positioned as one of the first healthcare provid- ers consulted by an individual demon- strating disordered eating behaviour. According to the National Prac- tice Standards for Eating Disorders, a document drawn up by the NEDC, dental professionals fall into the group of early identifiers and initial responders. They are defined as fol- lows: “Early identifiers have a duty of care for the well-being of people in high-risk groups for eating dis- orders and who are most likely to act as the first point of contact for people with eating disorders and their families. The role of early iden- tifiers is to proactively engage peo- ple at risk to promote prevention and early help seeking.” Intra-oral manifestations of nu- tritional deficiency present early in the clinical course of an eating dis- order, and general tooth erosion can take approximately two years to appear. Swelling around the cheeks or jaw or bad breath can be physical warning signs of frequent vomiting. The ability of the oral health practitioner to recognise the subtle changes in the mouth of a patient is central to identifying early indicators of an eating disor- der as early as possible. The NEDC first partnered with the ADA New South Wales (NSW-, as part of a combined project, where ADA NSW undertook a focus group of some of their members to un- derstand their perspective on eat- ing disorders, including how to ap- Eating disorders are serious mental health conditions which have a significant and underestimated impact on Australian society.

The feedback of this focus group resulted in the development of e-learning resources and provided significant progress in identifying the gaps that exist in the knowledge and identification of eating disor- ders and practices for a standard approach to care for patients with an eating disorder. When contacted by Dental Tri- bune International, the NEDC ex- plained that working with the ADA in some way to create awareness of the oral health practitioner’s posi- tion in the identification, treatment and management of an eating dis- order was important and was the perfect partner to promote this cause. The NEDC believes that as an organisation the ADA shares simi- lar values to that of the NEDC. With a focus on collaboration, profes- sionalism, integrity and respect, the NEDC felt that these values aligned with their own. It is the goal of the NEDC to work collaboratively across the sector to provide better outcomes for all Aus- tralians living with an eating dis- order, through the sharing and de- velopment of evidence-based, na- tionally consistent information and standards. Researchers recruit Pasifika adolescents for oral health study By DTI DUNEDIN, New Zealand: The mul- ticultural element of New Zealand society is something that brings with it many positives, but it can also create certain barriers for some groups. Among these many cultures, the Pacific Islanders make up a large proportion of the soci- ety, and in a new study, research- ers from the University of Otago in Dunedin recruited Pasifika ad- olescents to interview groups of their peers about their under- standing and experiences of oral healthcare and their attitudes to- wards it. Despite dental care being free for all New Zealanders under 18, re- search shows that Pasifika adoles- cents living in New Zealand are less In a new study, researchers have gone straight to the source to find out why adolescents from the Pacific Islands living in New Zealand are less likely to visit the dentist than their peers of other ethnicities. (Photograph: AsiaTravel/Shutterstock) likely than their peers of other eth- nicities to access it. In the first study of its kind, the researchers decided to source information directly from the group of interest in order to un- derstand more accurately why this might be and what some of the most significant issues are. According to the study, 17 Pas- ifika adolescents from four cities in various parts of New Zealand facil- itated focus groups with 59 of their Pasifika peers. From the data col- lected, the researchers then con- ducted an inductive thematic anal- ysis, and the paper focused on one central theme that emerged: the participants’ suggestions for increas- ing access to oral healthcare. Sug- gestions included reducing the cost of oral healthcare and oral health products; making access to clinics easier, including having transport arranged or having dentists visit schools; making the clinical envi- ronment more welcoming and youth- friendly; and having more approach- able, younger and Pasifika or Maori oral health professionals working in the dental profession. “Policymakers should look at implementing at least some of these suggestions for change, or at least treating them as a conversation starter on how to address the ineq- uities in Pasifika adolescents’ oral healthcare access,” said lead author Dr Lee Smith, a research fellow in the Faculty of Dentistry at the Uni- versity of Otago. Other recommendations dealt with increasing the emphasis placed on oral health in Pasifika families and communities through educa- tion, for example, by means of pam- phlet drops in churches and adver- tising on visual and social media. It was suggested that this may be more effective in Pasifika languages. The study, titled “Pasifika adoles- cents’ recommendations for increas- ing access to oral health care”, was published in the March 2019 issue of the New Zealand Dental Journal.

The mandible is so well preserved that it allows for a virtual re- construction of the two sides of the mandible. (Photograph: Jean-Jacques Hublin) LANZHOU, China: The journey that Homo sapiens has embarked on is something that has enthralled mod- ern scientists for many centuries. Now, as technology continually im- proves, more understanding is being gained and new discoveries are com- ing to the surface. Recently, research- ers revealed that a sister group of Neanderthals, the Denisovans, occu- pied the Tibetan Plateau long before Homo sapiens arrived in the region. This discovery was made through the analysis of a 160,000-year-old hominin mandible. “Traces of Denisovan DNA are found in present-day Asian, Aus- tralian, and Melanesian popula- tions, suggesting that these ancient hominins may have once been widespread,” said Prof. Jean-Jacques Hublin, Director of the Department of Human Evolution at the Max Planck Institute for Evolutionary Anthropology (MPI-EVA- in Leipzig in Germany and one of the paper’s co-authors. “Yet, so far, the only fos- sils representing this ancient homi- nin group were identified at Den- isova Cave.” The fossil, originally discovered in 1980 by a local monk, was eventu- ally passed on to Lanzhou Univer- sity, and in 2010, researchers Prof. Fahu Chen and Dr Dongju Zhang began studying the cave site where the fossil had been found In 2016, Lanzhou University initiated a collaboration with the Department of Human Evolution at the MPI-EVA and since then they have been jointly analysing the fos- sil. According to the researchers, DNA was not able to be recovered from the mandible itself but rather from one of the molars, which they examined by means of ancient pro- tein analysis. From that analysis, the team found that the mandible came from a member of a Deniso- van group from Siberia—something that confirms Denisovans had al- ready been living in the high-alti- tude setting significantly prior to the appearance of Homo sapiens. With continued research and analysis planned for the future, the team now hope that the lower jaw can aid in piecing together the puz- zle of what Denisovans looked like. In their study, the researchers examined a mandible that was found on the Tibetan Plateau in Baishiya Karst Cave in Xiahe County in China. The study, titled “A late Middle Pleistocene Denisovan mandible from the Tibetan Plateau”, was pub- lished on 1 May 2019 in Nature.. ADA will continue its push for affordable dental care after Australian election By DTI SYDNEY, Australia: A few days after the Australian elections, the Aus- tralian Dental Association (ADA- has reaffirmed its commitment to collaborating with the re-elected coalition government to improve Australia’s dental health and to im- plement the ADA’s Australian Den- tal Health Plan (ADHP-. The election result follows a campaign in which the Australian Labor Party pledged A$2.4 billion to a pensioner dental plan, which w o u l d h a v e i n v e s t e d u p t o A$2 million in older Australians’ improved access to dental care. The Au st r a l i a n Gr e e n s we r e planning to invest A$5.8 billion in Medicare-funded dental care.

These groups i nc lude c h i ld ren , adu lts a nd seniors from lower socio-economic backgrounds, Abor iginal and Torres Strait Islander people from rural and remote areas, and those with special needs. Despite Labor’s loss, the empha- sis on fulfilling the ADHP will con- tinue with a coalition government, noted ADA President Dr Carmelo Bonanno. “During the election, the ADA was overwhelmed by feedback from both ADA branches around Australia and the public about the desperate need to provide oral healthcare to disadvantaged groups.” “This is a critical area for the coalition government to address the needs of the disadvantaged for whom public waiting lists mean their oral health declines while they wait to be treated,” he explained. “Everyone in Australia, regardless of their ability to pay, should be able to receive dental care. Our goal is a robust model of a mix of afford- able public and private dentistry which accommodates the dental needs of the whole community.” The ADA has long lobbied suc- cessive federal governments to ad- dress the urgent and growing need for additional, targeted and sustain- able funding to meet the require- ments of disadvantaged Australians, and it will continue its push for af- fordable oral healthcare with the re-elected coalition government. The Australian Dental Association has expressed its commitment to its continued work with the newly re-elected coalition to achieve affordable dental healthcare. (Photograph: Robert Kneschke/Shutterstock) “We look forward to continue working with Minister [Gregory Andrew] Hunt to improve the den- tal health of the Australian public and will be lobbying for implemen- tation of the ADA’s Australian Den- tal Health Plan,” Bonanno said. “As a non-partisan organisation, the ADA has long-standing relation- ships with both sides of the politi- cal divide. We will work productively with both the coalition government and the Labor opposition to bring about good policy for dentists and the Australians they treat.”
