The event attracted 1,135 attendees, representing 34 coun- tries, who were engaged by an ex- citing mix of scientific presentations by leading international dental ex- perts and new product launches by the exhibiting companies. The Dental Hygienists Associ- ation of Australia, in collaboration with the International Federation of Dental Hygienists (IFDH), hosted the event under the theme of “Lead- ership, Empowerment, Advances, Diversity” or LEAD. The symposium opened with a welcome-to-the- country ceremony featuring mem- b er s of t he lo c a l i nd igenous community and this was followed, after lunch, by keynote presenta- tions by Drs Ron Knevel and Dag- mar Else Slot, among others. The next day, Ann Battrell, CEO of the American Dental Hygienists’ Association (ADHA), and Matt Cre- spin, President of the ADHA, to- gether delivered a well-received presentation titled “The wise in- vestment: Strategic dental hygiene leadership development.” A gala dinner was held at the picturesque Howard Smith Wharves that night, with a live band providing attend- ees with a welcome opportunity to let their hair down. Anh Do, a Vietnamese-born Australian comedian, writer and artist, delivered the keynote speech on the final day of the ISDH. Do’s humorous and heart-warming pre- sentation, which focused on his journey from refugee to becoming one of Australia’s most loved enter- tainers, was extremely well received by attendees.

AD By DTI OTAGO, New Zealand: Not all den- tal practitioners may be aware of the finer details of dentistry equip- ment. Helene Chua, a 21-year-old fourth-year University of Otago Bachelor of Dental Surgery stu- dent, has recently made headlines with her research into the cooling efficiency of different numbers of water coolant ports on high- speed handpieces. Her findings point to the potential for signifi- cant savings for dentists around the world. Chua received the Otago Medical Research Foundation’s 2018/19 Sum- mer Research Scholarship for her research. She compared four-port high-speed handpiece systems to single-port systems to see which produced better cooling results. Her results indicated that four-port systems led to better cooling, but no statistically significant differ- ence was found. Chua believes this finding may help improve hand- pieces and make them more com- fortable in the future. Dr Joanne Choi (left), and Associate Professor Neil Waddell have been impressed with dental student Helene Chua’s research which demonstrated that multi- coolant-port high-speed handpieces do not offer statistically significant cooling improvements over single-coolant-port varieties. (Photograph: Otago University) The findings could also mean sig- nificant savings for practitioners, as a four-coolant-port handpiece costs around NZ$1,800, compared with the single-port variety, which costs around NZ$800. “Not many dentists know about the specifics of the tools they are using, and this research gives them information for choosing what to buy and use,” said Chua. “Opportunities like this give un- dergraduate students a taste of re- search, and that can encourage them to pursue postgraduate stud- ies and possible future academic careers. It also lets students under- st a nd t he i mp or t a nc e of r e - search-informed teaching and re- search-based practice as a dental professional,” said research super- visor Dr Joanne Choi.

02 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 04/2019 Improving oral health of people with intellectual disability By DTI MEVBOURNE, Victoria, Australia: Peo- ple with intellectual disability face various social, conceptual and other challenges that affect their overall health and well-being. Some of these challenges may also affect oral health. In order to educate dental practi- tioners on the issue and to improve access to dental care for individuals with intellectual disabilities, the In- clusion Designlab has published a guide that is aimed at fostering col- AD laboration between medical provid- ers, key support professionals, ac- commodation services and families, and identifying and subsequently treating oral health diseases more effectively. According to the Australian Fed- eration of Disability Organisations, almost one in five Australians re- ported living with disability in 2015 and a child was diagnosed with an intellectual disability every 2 hours. Having an intellectual disability may affect a person’s participation in the community, financial status, level of education attained, employment op- portunities and intellectual func- tioning. According to the National Institute of Dental and Craniofacial Research, a branch of the US National Institutes of Health, people with in- tellectual disability also suffer from untreated dental caries and a high prevalence of gingivitis. Other oral health problems include a higher risk of malocclusion, missing permanent teeth and poor oral health habits. The Inclusion Designlab has recently published a guide on oral health and intellectual disability for dental practitioners. (Photograph: anatoliy_ gleb/Shutterstock) The guide for dental practitioners was developed by Inclusion Mel- bourne, Monash Health’s Centre for Developmental Disability Health, the Australian Dental Association, the Australian Society of Special Care in Dentistry and other representa- tives from the health sector. It details main components, protocols and recommendations for health profes- sionals and family members that pertain to oral health and intellec- tual disability. Besides offering gen- eral information on the disorder, the guide offers dental practitioners clear guidance on how to behave during a dental visit, informs them about the possible conditions that could be detected in patients with intellectual disability and recommends suitable treatment pathways and strategies to achieve desirable health outcomes. As individuals with intellectual disability may not always be able to communicate and express them- selves clearly, the guide also recom- mends how to facilitate and improve communication between dental practitioners and people with dis- ability. Finally, it includes forms that aid effective planning between sup- port professionals, dentists and med- ical practitioners.
Dental Tribune Asia Paciﬁc Edition | 04/2019 ASIA PACIFIC NEWS 03 New research highlights relationship between scent and disease By DTI subayashi, results show that the device can detect a broader range of VOC levels than other devices and may aid in the further study of the relationship between scent and disease. The study, titled “Ultrasensitive sniff-cam for biofluorometric-imaging of breath ethanol caused by metabo- lism of intestinal flora”, was published online on 9 July 2019 in Analytical Chem- istry, ahead of inclusion in an issue. AD Tetric® N-Line High-quality composites for esthetic anterior and posterior restorations High-quality composites for esthetic anterior and posterior restorations Researchers in Japan have developed a gas imaging system that can detect compounds linked to some illnesses. (Photograph: UfaBizPhoto/ Shutterstock) TOKYO, Japan: Bad breath can be caused by any number of things, including an illness. When there is more to it than just an overload of onions and garlic, it can be difficult for practitioners to make an accu- rate diagnosis. For the first time, researchers in Japan have developed a highly sensitive gas imaging sys- tem (“sniff-cam”) that can detect low diagnostic levels of some dis- ease biomarkers. Building on previous versions of their sniff-cam that can detect volatile organic compounds (VOCs), scientists from Tokyo Medical and Dental University have recently de- veloped a device that can detect compounds linked to illnesses such as diabetes, lung cancer and Par- kinson’s disease. Speaking to Dental Tribune International, lead researcher Prof. Kohji Mitsubayashi said they had developed three types of gas imaging systems and that the latest version uses an ultraviolet (UV) ring light, UV filters and a camera. Mitsubayashi explained how the UV ring light was placed in the vicinity of the charge-coupled device (CCD) lens for real-time gas imaging from the target object. An enzyme mesh is placed be- tween the CCD and the target ob- ject. As the ring light irradiates the enzyme mesh, the CCD is able to take a gas image from the di- rection of the UV irradiation. The novel bio-fluorometric gas imag- ing system performs well, demon- strating real-time gas imaging, high sensitivity, gas selectivity and a short response time to the gaseous chemical coming from the target object. To test the effectiveness of the sniff-cam, researchers worked with a group of male subjects who had not consumed food or drink for a certain period. The device detected miniscule levels of gaseous ethanol in their breath.

Dental Tribune Asia Paciﬁc Edition | 04/2019 ASIA PACIFIC NEWS 05 Indian dentists extract 526 teeth from boy’s mouth By DTI CHENNAI, India: In a remarkable 2-hour operation, doctors at the Saveetha Dental College and Hos- pital have reportedly removed 526 teeth from the mouth of a 7-year- old boy. The teeth were discovered inside a sac embedded in the pos- terior region of his lower jaw. Den- tists are unsure whether the cause was genetic or environmental. Ramani commented that, sur- prisingly, the boy was barely in any discomfort. “The only thing which was bothering him was that the tooth on that side had not erupted, it was empty, and [he had] occa- sional pain, and there was slight swelling that was increasing in size,” she added. The boy, who now has just 21 teeth, was discharged from the hospital after three days and is recovering well.

(Photograph: sebra/Shutterstock) The boy was brought into the hospital after complaining of pain and swelling in his jaw. It was dis- covered that he was suffering from compound composite odontoma. “The tumour-like growth prevented permanent molar teeth growth in the boy in the affected side,” said Dr P. Senthilnathan of Saveetha Dental College and Hospital’s Department of Oral and Maxillofacial Surgery in an interview with the New Indian Express. “X-ray and CT scan showed multiple, rudimentary teeth in a bag-like tissue. It took 5 hours to re- move all the minute teeth from the bag-like structure. The weight of the growth was 200 grams.” At the age of 3, the boy had been taken to a nearby hospital when his parents had noticed slight swell- ing in the same area, but he did not undergo any procedures, partly because of his youth. To the knowl- edge of the hospital, the total of 526 teeth removed from the boy’s mouth is unmatched by any other case, though a 17-year-old boy in Mumbai had 232 teeth removed in 2014. “The teeth were of variable sizes that ranged from smallest at 0.1 mm to largest 3 mm. They had a small crown, enamel and a small root,” said Dr Pratibha Ramani, head of the hospital’s Department of Oral and Maxillofacial Pathology, in an interview with The Guardian.
06 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 04/2019 Reflux associated with temporomandibular disorder, a recent study finds By DTI XIAN, China: Reflux is an uncom- fortable condition that can have negative effects on a patient’s oral health. In a recent study, research- ers have established that temporo- mandibular disorder (TMD) is as- sociated with gastro-oesophageal reflux (GERD). Other factors such as anxiety and poor sleep contrib- ute to this correlation. The authors of the study have noted that phy- sicians need to be aware of the as- sociation and consider instituting multidisciplinary management programmes to help patients. AD REGISTER FOR FREE!

Tribune Group GmbH designates this activity for one continuing education credit. An international team of re- searchers looked at data from two separate hospitals in China on 1,522 patients aged between 18 and 70 years old with chronic TMD. They set out to understand the connec- tion between the disorder and GERD and to determine whether anxiety, somatisation and depression influ- ence the association. In the study, co-author Dr Jihua Chen, from the Air Force Military Medical University in Xian, noted that the relationship between chronic musculoskeletal diseases, gastro-intestinal diseases, mental disorders and sleep problems is complicated. “There is evidence to support the bidirectional nature of the associations among these co- morbidities,” Chen said. He ex- plained that patients may be stuck in a cycle that undermines sleep. Somatization and anxiety exacer- bate the pain, and this pain can lead to sleep problems and mental dis- orders. An international team of researchers from China and the US have found that gastro-oesophageal reflux is associated with temporomandibular disorder. (Photograph: GBALLGIGGSPHOTO/Shutterstock) According to the results of the study, symptomatic GERD is a risk factor for TMD, and people with a longer history of GERD have a higher risk of TMD than those with a shorter history. “Patients with both chronic TMD and reflux symptoms may be underdiagnosed, resulting in de- ferred effective treatment and a prolonged disease course,” said Chen. The study, titled “Associations among gastroesophageal reflux dis- ease, mental disorders, sleep and chronic temporomandibular disor- der: A case–control study”, was pub- lished on 19 August 2019 in the Ca- nadian Medical Association Journal.
