The data revealed that the majority of the study participants struggle to meet rising dental care costs in the country. The survey interviewed a total of 1,438 members of the public aged between 25 and 60 years. All the re- spondents were Singaporeans, ex- cept for 26 permanent residents. More than two-thirds of the respon- dents (71%) visited private dental practitioners and 29% visited public healthcare institutions. The findings indicated that a staggering 89% of the study partic- ipants were unhappy about current dental care costs, and a third of the participants said that they would seek treatment overseas or turn to public healthcare institutions in the event of a further dental care cost increase. Nearly a fifth of the respondents stated that they had not visited a dentist in the last three years. However, those who had vis- ited a dentist at least once in the last year were happy about the ser- vice they had received and had not filed any complaints against their dentist. “The public survey gave us an opportunity to get a glimpse into the thoughts of Singaporeans and permanent residents. We are glad to find out that, despite the media reports on dentists recently, the survey reveals a very high confi- dence level in our dentists with regard to safety and competency in the delivery of dental care,” said chairman of the standing commit- tee Dr Tang Kok Weng. “We share the public concern about the rising dental treatment fees. We hope that there are no external factors in the near future that may poten- tially increase the cost of delivery of dental care in Singapore,” he concluded. Besides the rising dental care costs, 76% of the respondents were concerned about the rising cost of living in Singapore. A recent survey revealed that nine out of ten people in Singapore are concerned about high dental care costs.

The Dental Board of Aus- tralia requires every registered dentist to complete 60 hours of continuing professional develop- ment (CPD) over a three-year cycle, and the current cycle finishes on 30 November this year. There are a number of ways to meet this industry-set standard, from online webinars, such as those offered by the Dental Tribune Study Club, to seminars held by Austra- lian Dental Association (ADA) branches and other healthcare and clinical organisations. However, owing to the number of options, which include peer-to-peer study and discussion groups, it is import- ant to understand what, exactly, is classed as CPD accreditation. The ADA and the Dental Board of Australia have laid out several The three-year cycle in which Australian dentists are required to complete their 60 hours of continuing education is due to end on 30 November.

Content of CPD courses must be evidence-based. If the CPD activity includes an as- sessment or feedback activity, this should be designed to go beyond the simple recall of facts and should seek to demonstrate learning with an emphasis on the integration and use of the knowledge in professional practice. Many different CPD options are available, and sometimes, in seek- ing to make the right choice, the practitioner might find that the in- formation provided is confusing or unhelpful. The ADA has always made itself available for questions should practitioners need any assistance. The Dental Board of Australia too provides guidance in this area.

02 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 05/2019 Study identifies cells in gingivae that protect against periodontitis By DTI PHILADELPHIA, U.S./CHENGDU, China: Despite significant advance- ments in oral health care, peri- odontitis remains the most com- mon cause of tooth loss, as well as the sixth most prevalent infectious disease worldwide. The discovery of a new type of cell in the epithe- lial tissue of the periodontium that helps protect against harmful bac- teria has thus renewed interest in the notion that our immune sys- tems may be key to this disease. The study was conducted by re- searchers at the Monell Chemical Senses Center, a nonprofit indepen- dent scientific institute, working alongside scientists from Sichuan University in Chengdu in China. Examining the gingivae of mice, they found that solitary chemosen- sory cells (SCCs) were present and that they expressed several kinds of taste receptors as well as the pro- tein gustducin. The role of SCCs is to sense any irritants and bacteria that are present, and they have pre- viously been found in the urinary tract, the gut and the nasal cavities. The researchers showed that, when gustducin and/or SCCs were genetically removed from the mice’s gingivae, pathogenic oral bacteria often quickly grew in numbers, leading to periodontitis. In contrast, the stimulation of the bitter taste receptors in SCCs was found to pro- mote the production of antimicro- bial molecules. In general, mice without gust- ducin in their SCCs were found to have a more potentially harmful oral microbiome than those with gustducin present. Crucially, these differences in oral flora composi- AD A new study has indicated that molecular pathways in periodontal solitary chemosensory cells are involved in the regulation of oral microbiota.

Dental Tribune Asia Paciﬁc Edition | 05/2019 ASIA PACIFIC NEWS 03 ADA offers advice on how to handle dental scrap By DTI SYDNEY, Australia: The Australian Dental Association (ADA) has re- cently published an article in which it discusses the best practices for recycling dental scrap. Although many dentists treat it as waste, den- tal scrap can be recycled by an ex- perienced refiner. This is an envi- ronmentally friendly solution that will generate additional income for the dental practice. other one could contain up to 50% gold, which is why recycling all dental scrap through a metal re- finery is the only way to ensure fair compensation.Besides gold, recycled palladium could bring profit to the dental office. The ar- ticle cautions that dentists who only collect scrap material with a golden-yellow colour could be wasting up to 50% of the value in their dental scrap. AD Tetric® N-Line High-quality composites for esthetic anterior and posterior restorations High-quality composites for esthetic anterior and posterior restorations A recent article published by the Australian Dental Association has urged dentists to separate and sell the valuable precious metals found within the dental scrap to benefit their employees, patients and practice, and the environment. (Photograph: PHOTO FUN/ Shutterstock) Dental offices often discard den- tal scrap without considering the value of recycling it, the potential revenue this could produce or its impact on the environment. It is true that materials such as silver and mercury can negatively affect the environment and should, there- fore, be responsibly recycled. More- over, since dental scrap such as bridges, inlays and different types of crowns, including porcelain- fused-to-metal crowns, typically contain a mixture of gold, platinum, palladium or silver, recycling can be profitable. With the help of an experienced refiner, the precious metals in the dental scrap can be easily isolated and later sold instead of ending up in landfills. According to the article, amal- gam waste and dental scrap are two completely different materials that should not be treated in the same way by dentists. Instead, valuable dental material should be separated from amalgam. Every dental alloy is unique and requires an assay to determine its composition. Similarly, the combination of materials of which dental implants and other resto- rations are composed differs.

Tourette’s syndrome is charac- terised by repetitive movements or vocalisations known as tics. The negative impact that these can have on a person’s life is significant. Al- though there is no cure for the syn- drome, there are several treatment options. However, results can take some time. Aiming to help patients who suffer from Tourette’s syndrome, researchers have developed a removable dental appliance for both children and adults. (Photograph: othmane Sahnoun/Shutterstock) Speaking about the mouthpiece, one of the first authors of the study, Dr Jumpei Murakami from Osaka University, said, “Biting down on the device immediately improved both motor and vocal tics in ten of the 14 children and six of the eight adults that participated in the study. What’s more, these effects were long lasting. Long-term improvements in motor tics after more than 100 days were especially evident in pa- tients who were younger when their tics first started.” The researchers developed a custom-made oral splint similar to that used in the treatment of tem- poromandibular disorders. They applied it to the study participants’ molars, and this then realigned the nose, lips and chin. In the study, the team reported that the positive re- sults from biting down on the splint may be due to something known as sensory tricks. Sensory tricks are voluntary manoeuvres that usually involve touching parts of the face and head, and which can alleviate involuntary movements. “Consid- ering previous findings on sensory tricks in patients with cervical dys- tonia, it seems possible that the oral splint modulates proprioceptive, or ‘touch’ signals,” explained the other first author of the study, Dr Yoshihisa Tachibana from Kobe University. Recognising that larger-scale studies are required to test the ef- fectiveness of the oral device, the researchers noted that it has clear therapeutic potential that could improve the quality of life for those suffering from Tourette’s syndrome.

This distribution company will serve the dental communities in Hong Kong and Macau in China from the fourth quarter of this year. Strau- mann and Modern Dental Group will invest substantially in the joint venture and will own respective stakes of 40% and 60%. Financial details were not disclosed. Straumann’s dental implant products have been available for many years in Hong Kong through its long-standing local distribution partner, Advance Dental Consult- ing, which has made an important contribution to the establishment of Straumann as a local market leader. However, further invest- ment in the distribution channel is necessary in order to cater for the group’s rapidly expanding business portfolio and forthcom- ing launches. Straumann has there- fore reached an agreement with Advance Dental Consulting that enables Peak Dental Solutions to take over the distribution of its products.

To offer further levels of affordabil- ity, the group has added Anthogyr to its implant portfolio alongside Neodent and MEDENTiKA, which are complemented by attractively priced implant options from T-Plus and Warantec. One of the most exciting areas of expansion is the digital segment, where Straumann’s most recent additions include the TRIOS, CS 3600 and Virtuo Vivo intra-oral scanners, as well as Medit laboratory scan- ners, not forgetting its range of milling machines and 3D printers. Furthermore, the group is prepar- ing to enter the Asian clear aligner market with ClearCorrect and Smy- letec. Its goal is to make all of these solutions available to more custom- ers in Hong Kong and Macau from a single service partner. Peak Dental Solutions will have at its disposal the broadest range of replacement, restorative, correc- tive and digital dental solutions, and it will have access to the com- bined customer base of both com- panies, enabling it to capitalise on cross-selling opportunities. It will collaborate with Modern Dental Laboratory to develop and provide educational programmes via the Center of Dental Education in Hong Kong. Beyond this, customers will have access to the education and support networks of Straumann and the International Team for Im- plantology. Poor water quality may be factor in high consumption of sugary drinks By DTI CANBERRA, Australia: The poor state of Australians’ oral health has re- ceived much needed attention over recent years. For some Aboriginal and Torres Strait Islander people, particularly those living in remote communities, their oral health is being severely compromised owing to the consumption of sugary drinks, according to a recent study by re- searchers from the Australian Na- tional University (ANU). According to Rethink Sugary Drink, some male Australians aged between 12 and 24 consume 1.5 li- tres of soft drinks, sports drinks or energy drinks a day. High consump- tion of such beverages has had a huge impact on the oral health of Study finds poor-quality drinking water in remote parts of Australia may be one reason for high consumption of sugary drinks from a young age. (Photograph: Elizaveta Galitckaia/Shutterstock) many people, and calls for better labelling and sugar tax have been made to help mitigate the situation. However, for Aboriginal and Torres Strait Islander people in remote communities, it is not only that they are consuming these drinks, but also, according to this recent study, many of them feel that they have no healthier option, owing to the poor quality of drinking water. “Families living in regional and re- mote settings have expressed con- cern about the safety and quality of drinking water,” said lead author Dr Katherine Thurber. What is perhaps more concern- ing is that the habit of high con- sumption of sugary drinks is intro- duced at a very young age. In the study, researchers focused their attention on infants and toddlers aged 0–3 years. Data was gathered from 900 participants, and the re- sults showed that 50% had con- sumed some form of sugary drink. Cordial was the beverage most com- monly consumed at 47%, followed by soft drinks at 19% and sweetened tea and coffee at 13%. The remain- ing 50% of the participants had not consumed any form of sugary drink in their first three years of life, which researchers noted as a positive in the otherwise concerning results. Speaking about what could be done to make improvements, Thurber said, “Families need rele- vant advice from health profession- als, but improving information and knowledge is only one part of the solution. We also need programmes and policies to improve the social determinants of health if we want to improve nutrition.” The gap between the oral health of Aboriginal and non-Aboriginal Australians is closing, which indi- cates that the national focus on the issue may be having an impact. As reported by the researchers at ANU, babies and toddlers living in cities and regional centres were significantly less likely to consume sugary drinks than were children in remote areas. However, as re- ported recently by Dental Tribune International, 90% of Australian adults experience caries in their permanent teeth, and therefore, there is still plenty of work to be done. The study, titled “Sugar-sweet- ened beverage consumption among Indigenous Australian children aged 0–3 years and association with sociodemographic, life circum- stances and health factors”, was published on 28 August 2019 in Public Health Nutrition, ahead of inclusion in an issue.

08 WORLD NEWS Dental Tribune Asia Paciﬁc Edition | 05/2019 Scientists to develop novel dental restorative material By DTI TORONTO, Canada: Researchers from the University of Toronto (U of T) have recently been awarded a grant to develop a new restorative material for treating dental caries. The goal is to create a tooth-colored material that will not degrade when it comes into contact with saliva or when it encounters the body’s immune re- sponse. The grant will help address the failure of dental restorations and consequently reduce treatment costs. AD The grant, awarded by the Ca- nadian Institutes of Health Research (CIH R) and wor t h C$939,040 (€648,000), is aimed at reducing root and recurrent dental caries. According to the researchers, the aforementioned oral health diseases are especially prevalent in disad- vantaged populations. In popula- tions where oral health and hygiene is d i f f ic u lt or comprom ised, tooth-colored fillings often fail pre- maturely and may require contin- ual replacement. The polymer material will be tested in different oral conditions. “We are able to replicate the inter- actions of restorative materials with saliva, bacteria and the immune system for the development of a novel restorative system for cervical lesions with enhanced perfor- mance using much more rigorous testing than ever before,” said Prof. Yoav Finer, George Zarb/Nobel Bio- care Chair in Prosthodontics in the Faculty of Dentistry at the U of T. “This funding further exempli- fies the deep and comprehensive programs in applied biomaterials research that exist in the Faculty of Dentistry at the University of Toronto, with CIHR grants such as this one led by an internationally recognized clinician scientist and supported by outstanding research engineers and scientists,” said Prof. Paul Santerre, also from the U of T Faculty of Dentistry. “This is an important clinical problem with especially negative effects on the health of vulnerable populations,” said Prof. Bernhard Ganss, Vice Dean of Research in the faculty. “But with this kind of deeply collaborative, multidisciplinary ap- proach, we can fundamentally change long-term outcomes for people and alter the landscape of oral health care.” The researchers hope to com- mercialize the material through a health technology startup com- pany called Mesosil, headed by Dr. Cameron Stewart. More informa- tion about Mesosil can be obtained here. A multidisciplinary research team at the University of Toronto has been awarded a five-year grant to develop a better dental restorative system.
