The aim of the study was to show that greater transparency on added sugar in packaged foods is necessary. The researchers ana- Drop in denture use lysed more than 34,000 packaged foods—about 18,000 discretionary foods (those not necessary to provide the nutrients the body needs) and nearly 16,000 core foods, like milk, cheese and bread— to learn how the labelling could be improved if added sugars were included. A report published earlier this year found that consumers could avoid 26 teaspoons of sugar a day if they could identify added sugars on food packs. The study, titled “Incorporating added sugar improves the performance of the Health Star Rating front-of-pack labelling system in Australia”, was published on 5 July in the Nutrients journal. In an interview with Dental Tribune, Cole explained the underlying reasons for this: “The current cohort of older adults has benefited from substantial improvements made after the post-war boom. These improvements include community water fluoridation and use of fluoride toothpaste, advancement in dental technology and treatment methods, access to healthier diets, improved oral hygiene and more regular dental check-ups.” IV_Image_Anz_102x128_Layout 1 01.12.11 17:10 Seite 1 AD Erosive potential George Loh, Dr Yeoh Khay Guan, Dr Lily Chan, Amrin Amin, Dr Lim Jui, Prof. Kee Chaing Chua and Kelvin Zin (from left) at the launch of the NUS Centre for Additive Manufacturing. ” News Page 02 World’s Humans’ arrival in Asia longest tooth According to recent fossil teeth findings, the human dispersal out of Africa and down to Australia may have occurred 20,000 years earlier than previously thought. Using a new dating program, it was confirmed that the teeth came from modern humans, Homo sapiens, and most interestingly that they dated to as long as 73,000 years ago. ” Page 13 MELBOURNE, Australia: From new figures indicating a decline in denture use in Victoria, it appears that more older people are retaining their natural dentition. The data, which was released by the Dental Health Services Victoria (DHSV), relates to the number of dentures provided by Victorian public dental clinics to patients aged 65 and older. Overall, there was a 21 per cent drop in denture use over the eight-year period considered. “Older people are keeping their teeth longer and we hope this trend will continue,” DHSV CEO Dr Deborah Cole said. Seven out of ten packaged goods sold in supermarkets contain added sugar, the study found. © NAMIC The Health Star Rating front-ofpack labelling system used in Australia rates the overall nutritional profile of packaged foods and includes total sugar content as one of the components. This has been criticised because sugars naturally present in some foods are treated the same as sugars added during processing. However, according to co-author of the study Prof. Bruce Neal, only labelling total sugar content is misleading. This is particularly true for discretionary products containing a great deal of added sugar. “Good sugars are an Read all about the first edition of the Indonesia Dental Congress and Exhibition in our today specialty section included in this issue. ” Page 06 Better sugar labelling required NEWTOWN, Australia: In a new study carried out by researchers at the George Institute for Global Health, it was found that a significant amount of sugar is added to foods. Owing to a decline in the oral health of Australians, dentists have called on food manufacturers to state on their packaging the amount of sugar added to the products, according to the Australian Dental Association. today IDEC 2017 An 18-year-old teenager from India holds the new Guinness World Record for the longest human tooth. With a length of 3.67 cm, the tooth beats the previous world record by almost 5 mm, the records committee confirmed. The canine was buccally located and surgically extracted for aesthetic reasons. The low cost and availability of acidic fruit juices, fruit drinks and carbonated beverages encourage their consumption, and this may lead to elevated prevalence of dental erosion. Researchers at the Federal University of Santa Catarina in Brazil recently evaluated the chemical characteristics of grape and orange juice and their erosive potential in the decrease of microhardness and the loss of enamel structure. The results showed that grape juices presented greater erosive potential than orange juices. Pure, powdered and concentrated grape juices showed similar loss of enamel structure to that of a cola soft drink. The erosive potential of the beverages was statistically correlated to pH, titratable acidity, and calcium, phosphate and fluoride concentrations.

The researchers used CT scan images of an eight-year-old child’s mandible to design a 3-D model that could be used to observe the forces produced by the jaw when biting and chewing. The aim of the research was to show the stress dispersion within the jaw as a person bites and chews. Researchers have developed a 3-D biomechanical model that shows the stress distribution within the jaw as a person bites and chews. AD Tetric N-Ceram Bulk Fill ® The efficient posterior composite “We designed the hard and soft tissues in the jaw and input the data we had about jaw movements into the software,” said Dr Babak Sarrafpour, an oral and maxillofacial pathologist and dentist at the University of Sydney. “We simulated both the back teeth and front teeth chewing and we could assess the stress on the teeth, bone and soft tissue.” Save 55% on time The multidisciplinary team at the university found that the chewing and biting actions of the jaw deform the thin layer of soft tissue surrounding the teeth that are yet to appear, which forces them outwards. During the study, a number of other hypotheses were investigated that were still unsupported by clinical evidence. “There were a number of hypotheses surrounding how adult teeth erupted. Perhaps it was from the root forming and pushing the tooth towards the oral cavity, maybe it was the blood pressure in the dental pulp or perhaps it was the periodontal ligaments forming and contracting, pushing against the tooth,” said Sarrafpour. More information about the research project can be found at the university’s website. Data available on request. A P E AT AS W O !

Therefore, the researchers developed another theory. “Perhaps soft tissue dental follicle around unerupted adult teeth acts as a mechanosensor in response to biting forces and remodels the surrounding bone in a way that carries the tooth to the mouth,” Sarrafpour explained. * Tetric® N-Ceram Bulk Fill Tetric® N-Flow Bulk Fill sculptable flowable www.ivoclarvivadent.com Ivoclar Vivadent AG Bendererstr. 2 | 9494 Schaan | Liechtenstein | Tel.: +423 235 35 35 | Fax: +423 235 33 60[4] => ASIA PACIFIC NEWS 04 Dental Tribune Asia Pacific Edition | 9/2017 Mobile breath analysis device promising for early disease diagnosis © Elvira Koneva/shutterstock.com By DTI SEOUL, South Korea: Breath pattern recognition was once thought of as a futuristic diagnostic platform. Research in this area has been gaining much attention because breath analysis is a non-invasive and lowcost method. Among the most critical challenges in this regard is the development of sufficiently sensitive sensors. Korean scientists have now developed high-sensitivity sensors to enable early monitoring of various diseases based on biomarker gases in breath. The research group, led by Dr Il-Doo Kim in the Department of Materials Science and Engineering at the Korea Advanced Institute of Science and Technology, has developed highly sensitive and selective chemiresistive sensors that can potentially diagnose specific diseases by analysing exhaled breath gases. The sensors were developed by combining hollow protein-templated nanocatalysts with electro- Breath analysis can detect trace changes in exhaled breath components, contributing to early diagnosis of disease. spun metal oxide nanostructures, which have large and highly porous surface areas and thus achieve high sensitivity. Human breath consists of iverse components, including d water vapour, hydrogen, acetone, toluene, ammonia, hydrogen sulphide and carbon monoxide, with greater or lesser amounts exhaled in the case of illness. Some of these are closely associated with diseases such as asthma, lung cancer, Type 1 diabetes mellitus, and halitosis. Breath analysis starts with capturing exhaled breath in a Tedlar bag and subsequently injecting the captured breath gases into a miniaturised sensor system, similar to an alcohol detector. It is possible to analyse exhaled breath very rapidly with a simple analysing process. Breath analysis can detect trace changes in exhaled breath components, contributing to early diagnosis of disease. However, gases in the breath occur at very low levels, from 1 ppb to 1 ppm, and so extremely sensitive sensors are needed for accuracy. In particular, it has been a challenge for chemiresistive chemical sensors to selectively detect specific biomarkers. Conventionally, platinum and palladium are used in developing the catalysts; however, the sensitivity is insufficient. The sensors in the current study were specially optimised for selective detection of specific biomarkers. Their performance was approxi- mately three to four times better than that of platinum and palladium catalyst-loaded nanofibre sensors. In particular, their sensitivity to acetone and hydrogen sulphide was the highest reported in literature. “New types of heterogeneous nanocatalysts were synthesised using protein templates with sizes around 2 nm and functionalised on various metal oxide nanofiber sensing layers. The established sensing libraries can detect biomarker species with high sensitivity and selectivity. The new and innovative breath gas analysis platform will be very helpful for reducing medical expenditures and continuous monitoring of physical conditions,” said Kim. The study, titled “Innovative nanosensor for disease diagnosis”, was published in the July issue of the Accounts of Chemical Research journal. Study evaluates digital scanners By DTI CHARLESTON, USA: With intraoral scanning becoming increasingly prevalent in dentistry, knowing which scanner will give the best performance is essential. In a new study led by Dr Walter Renne, from the Department of Oral Rehabilitation at the Medical University of South Carolina, re- searchers looked at seven scanners and analysed their performance based on 3-D comparisons. They found that Planmeca PlanScan and 3Shape’s TRIOS performed the best. The study’s main objective was to compare the trueness and precision of the scanners in both posterior sextant and complete- arch scenarios. Additionally, it looked at the time each scan required and correlated it with trueness and precision. To achieve the most accurate and no-bias results, a custom complete-arch model was fabricated with a refractive index similar to that of tooth structure. Six digital intraoral scanners and one digital laboratory scanner were used to scan the custom model for both scenarios. Analysis was performed using 3-D metrology software to measure discrepancies between the master model and experimental casts. According to the study, lanmeca PlanScan was found to P have the best trueness and preci- sion for sextant scanning, and 3Shape’s TRIOS the best balance of speed and accuracy for completearch scanning. The study, titled “Evaluation of the accuracy of 7 digital scanners: An in vitro analysis based on 3-dimensional comparisons,” was published in the July issue of the Journal of Prosthetic Dentistry.

In response to growing demand for the Dental Hygiene Clip Mirror, she has introduced the device to the US market and plans to expand her business globally. Dental Tribune Online spoke with Blundon, who has 30 years’ experience and graduated from the Algonquin College of Applied Arts and Technology in Ottawa, to learn more about the mirror. Helping to improve treatment has always been important in dentistry. Why did you decide on developing the Clip Mirror and set- ting up your business, D.H. Essentials? The Clip Mirror idea came to me about ten years into my career. I was working on a patient with a super strong lower lip and a protruding tongue. With a scaler in one hand and mirror in the other and the patient’s tongue pushing out the saliva ejector, I thought to myself, “Why does this need to be so hard?”. I thought about having a mirror clip directly on to the saliva ejector to free up a hand and wondered why no one had invented this. Then I thought to myself, “Who better to invent a dental tool than a dental hygienist?”. When designing the Clip Mirror, what did you pay attention to? I knew the design I wanted and I visited a multitude of hardware stores to see what clips were available. The steel for the clip had to be medical grade and 400 series so that it would not rust or corrode with sterilization, and the clip itself was designed to snap securely to the saliva ejector while still allowing rotation if needed. I designed the rolled clip ends so one can feed a line of floss through and attach the Clip Mirror to the saliva ejector using sterile tape as an added precaution in hospital set- tings or compromised patients. I chose the brighter size 5 titanium mirror, as the standard rhodium pales in brightness and quality in comparison, and then decided to tal clinicians may find themselves using a less than ideal posture while craning their necks and contorting their bodies to complete the necessary treatment. I would Dental hygienists have been asking about the Clip Mirror, stating they wish their employers would purchase them for their hygiene tray setups. Many have seen the value of “Dentistry can take a huge toll on one’s body.” encourage dental care providers to try various products to find what works best for them to help maintain proper posture, as we all know dentistry can take a huge toll on one’s body. Patricia Blundon, developer of the Dental Hygiene Clip Mirror, is dedicated to providing innovative quality tools for dental hygienists. have the clip electron beam welded by hand for the best results. What is the importance of good ergonomics for dental hygienists and clinicians? The key reason I designed the Clip Mirror was to make the job of dental hygienists and clinicians easier on their body and more efficient. As the population ages, den- What has user feedback been so far? Feedback on the Clip Mirror has been great, and for those who have struggled in the past, like I have, with no help from a dental nurse or assistant, it has been a great body and time saver. Many report finding it very helpful when they have a patient who cannot recline and need to scale the maxillary lingual surface. I have received some feedback requesting a smaller mirror size for use with patients with a narrow or smaller arch and will be introducing the Clip Mirror MINI in the near future. the Clip Mirror in increasing their productivity and easing the daily physical stressors of providing dental hygiene treatment. The majority of purchases are by dental hygienists who are already suffering from a career of dental hygiene. How has the success of the Clip Mirror been globally? I decided to introduce the Clip Mirror to the US after years of market research and positive feedback from my Canadian customers. I have had customer interest from Australia, Ireland and the UK and would love to team up with a partner to serve these markets and many others. Dentistry is worldwide, so the sky is the limit.

Planning and temporisation 5a 5b By Dr Torsten Seidenstricker & Dominique Vinci, Switzerland This patient case demonstrates how a monolithic zirconium dioxide framework can ensure stability and function in a complex prosthetic restoration. The ceramic veneering of the vestibular surfaces gives the restoration natural light optical properties, contributing to the very pleasing final results. Initial situation A 60-year-old patient came to the dental practice as an emer- 6 gency case. In addition to aesthetic and functional problems, there was severe periodontal damage. The treatment began with an in-depth diagnosis and an informative consultation. First, teeth #25, 26, 14, 16, 11 and 12 were extracted. The periodontitis was then targeted. Treatment of the periodontitis was successfully completed approximately 13 months later. Implants needed to be placed in regions #11, 12, 14, 16, 25 and 26. The clinical situation meant that all teeth in the maxilla and some teeth in the mandible had to be restored. 7a Before starting such an extensive prosthetic reconstruction, photographic documentation of the oral situation and the patient’s face is essential. Primarily, the photographs help in assessing the axes and planes in terms of optimum aesthetics and function. We work with a 3-D design program (Digital Smile System, DSS). This tool enables us to simulate the possible results virtually. Another advantage of this software is that the photographs can be used in the CAD software while the restoration is being produced. The teeth to be extracted were removed from the situation model, and the remaining teeth were prepared using the information provided by the dentist. On this foundation, we designed a wax-up with the CAD software (3Shape) and then transferred it to wax. This was the basis for a matrix made from transparent silicone, which was sent to the practice. After the dental preparation was complete (implant placement, preparation, etc.), the matrix was filled with an auto-polymerising temporary composite (Telio CS C&B, Ivoclar Vivadent) and a temporary restoration was produced and then inserted into the mouth. The temporary restoration served as a dental prosthesis during the implant healing phase, and it allowed us to determine whether the situation, which was planned in the laboratory, harmonised in a functional and aesthetic manner in the patient’s mouth. The patient wore the adapted temporary restoration for approximately six months up to the osseointegration of the implants. Production of the final dental restoration Implant abutments The wax-up was positioned on the master model and adapted based on the patient’s and dentist’s feedback. A double scan followed. We digitised both the model and the wax-up using the laboratory scanner. Subsequently, the implant abutments were produced via CAD/CAM. The implant abutments were milled from a new translucent zirconium dioxide material (IPS e.max ZirCAD, Ivoclar Vivadent). Before sintering, we stained the cervical areas of the frameworks. We used a liquid with a warm yellow tone for the infiltration. After sintering, the implant abutments were adhesively bonded to the titanium bases (TiBase, Straumann) with a luting composite (Multilink Hybrid Abutment, Shade HO, Ivoclar Vivadent) specifically designed for this indication. The self-curing composite provides excellent adhesion qualities. After adhesive bonding, the abutments were integrated. Production of the framework The following restorations were planned for the final prosthetic restoration: 1. a bridge in regions #11–13; 2. a bridge in regions #14–16; 3. a crown on tooth #17; 4. seven single crowns on teeth #21–24 and 27, as well as in regions #25 and 26. 7b Fig. 6: The CAD/CAM-fabricated abutments (hybrid abutments) were screwed on to the implants.—Figs. 7a & b: The CAD framework construction after the buccal areas had been cut back.[11] => 8a 11 TRENDS & APPLICATIONS Dental Tribune Asia Pacific Edition | 9/2017 8b 9 10 11 12a 12b Figs. 8a & b: Colouration of the zirconium dioxide before sintering.—Fig. 9: The zirconium dioxide frameworks prepared for veneering in the buccal area. —Fig. 10: The ceramic build-up in the anterior region (IPS e.max Ceram).—Fig. 11: Prepared for the second firing.

The buccal surfaces should be built up in ceramic in order to achieve optimum aesthetics. In preparation for this, the software performed a cut-back. After the framework design, the individual elements were milled from zirconium dioxide (IPS e.max ZirCAD). The material used has interesting mechanical properties, which, among other quali- ties, guarantee the long-term stability of the restorations. The selected shade of LT sun offers a light chroma that matched perfectly the envisaged Shade A restorations. After milling the frameworks, we corrected the morphology slightly, paying particular attention to the interdental areas. For excellent aesthetic results, we infiltrated the frameworks with the special IPS e.max ZirCAD LT colouring liquids (Ivoclar Vivadent) before sintering. 14 Fig. 14: The all-ceramic restorations looked very natural and vital in the mouth.[12] => 12 In the incisal and occlusal areas, the chroma was increased and the translucency was adapted in the appropriate areas. As only the buccal surfaces were veneered in this case, the framework volume was relatively solid. We always carry out a slow sintering procedure (9 h) in our laboratory for complex restorations, such as the reconstruction presented here. Subsequently, the surfaces of the monolithic TRENDS & APPLICATIONS zirconium dioxide parts were polished, paying special attention to the occlusal areas. For polishing, we used polishing cones from SHOFU or anaxdent. These cones guarantee thorough polishing so that the surface can subsequently be easily polished to a high lustre. We do not use silicone cones or discs, as they leave residues on the surface, making the application of glazing materials difficult. Areas that are dif- ficult to access during polishing are covered with a thin glaze layer. This was followed by a restoration try-in in the patient’s mouth. The dentist checked the occlusion and function. Veneering After conditioning of the framework parts to be veneered, a fluorescent liner (IPS e.max Ceram Dental Tribune Asia Pacific Edition | 9/2017 ZirLiner, Ivoclar Vivadent) was applied; this gave the restoration fluorescence from the depths in order to achieve light effects resembling that of the natural dentition. Non-fluorescent materials (e.g. pure zirconium dioxide) appear dull and dark. Since the framework was already coloured, we opted for a clear liner. This additionally enhanced the light transmission and contributed to the adhesion of the ceramic ve- AD neer to the zirconium dioxide. A classic ceramic veneering build-up was then carried out. We used a special indicator (Smile Line) to mix the ceramic powder in order to differentiate the individual materials better. The IPS e.max Ceram range includes Power materials, which provide an increased level of brightness, particularly for translucent framework materials. In this case, we decided to use the Power materials. A further advantage of the IPS e.max Ceram material is its excellent stability. The individual areas do not merge during the build-up of the ceramic veneer, allowing for the exact desired effects to be achieved. In order to achieve the correct shape, morphology and liveliness, a second firing was necessary. The restorations were then glazed and finished. We like to use the glaze material (IPS Ivocolor FLUO, Ivoclar Vivadent) in a creamy consistency. Conclusion In the design illustrated, only the buccal surfaces of the otherwise monolithic zirconium dioxide framework are veneered. An aesthetic and durably stable result was achieved with relatively minimal effort. The qualities of the materials are used to their full advantage. These include the excellent light optical properties of IPS e.max Ceram, in this case especially the Power materials; the high strength of zirconium dioxide; the possibility of colouring the zirconium dioxide to achieve a warmer colour effect (white zirconium dioxide is far too bright for this type of restoration, and reducing the degree of brightness would have been difficult in view of the low thickness of the veneering ceramic); and the low amount of ceramic material (this allows minimal controlled shrinkage and ensures easy handling).
