The data, which was released by the Dental Health Services Victoria (DHSV), re- lates to the number of dentures pro- vided 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. In an interview with Dental Tribune, Cole explained the underly- ing reasons for this: “The current co- hort of older adults has benefited from substantial improvements made after the post-war boom. These improvements include community water fluoridation and use of fluo- ride toothpaste, advancement in dental technology and treatment methods, access to healthier diets, improved oral hygiene and more regular dental check-ups.” By DTI NEWTOWN, Australia: In a new study carried out by researchers at the George Institute for Global Health, it was found that a signifi- cant amount of sugar is added to foods. Owing to a decline in the oral health of Australians, dentists have called on food manufactur- ers to state on their packaging the amount of sugar added to the products, according to the Australian Dental Association. The Health Star Rating front-of- pack labelling system used in Aus- tralia rates the overall nutritional profile of packaged foods and in- cludes total sugar content as one of the components. This has been crit- icised 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 con- tent is misleading. This is particu- larly true for discretionary prod- ucts containing a great deal of added sugar. “Good sugars are an Seven out of ten packaged goods sold in supermarkets contain added sugar, the study found. integral part of a healthy diet, and we need to be able to separate sug- ars naturally present in dairy, fruits and vegetables from sugars added during manufacturing,” he said. The aim of the study was to show that greater transparency on added sugar in packaged foods is necessary. The researchers ana- lysed more than 34,000 packaged foods—about 18,000 discretion- ary 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 in- cluded. 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 “Incorporat- ing added sugar improves the per- formance of the Health Star Rating front-of-pack labelling system in Australia”, was published on 5 July in the Nutrients journal. IV_Image_Anz_102z128_Layout 1 01.12.11 17:10 Seite 1 Erosive potential 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 den- tal erosion. Researchers at the Fed- eral University of Santa Catarina in Brazil recently evaluated the chemical characteristics of grape and orange juice and their erosive potential in the decrease of micro- hardness 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 fluo- ride concentrations.

Humans’ arrival in Asia World’s 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 con- firmed that the teeth came from modern humans, Homo sapiens, and most interestingly that they dated to as long as 73,000 years ago. 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 previ- ous world record by almost 5 mm, the records committee confirmed. The canine was buccally located and surgically extracted for aes- thetic reasons. AD Distinguished by innovation Healthy teeth produce a radiant smile.
