Summary
Over the past 20 years there have been significant gains made in the oral health of children, with the majority of 12 year olds in Australia in 1996 having no dental decay. There are however some indications that young adulthood may have become a period of increased risk of dental disease, as young adults leave home, become increasingly independent, have financial pressures whilst establishing themselves and change their diet and other habits.

There are however some indications that young adulthood may have become a period of increased risk of dental disease, as young adults leave home, become increasingly independent, have financial pressures whilst establishing themselves and change their diet and other habits. In 1998-99 a baseline study was conducted on a sample of Adelaide young adults 20-24 years using telephone interviews and oral examinations. Data was obtained on dental visiting patterns, socio-economic status, living arrangements, and health behaviours such as smoking and playing sport, as well as oral health. This study seeks to follow-up the sample of 1265 young adults who were interviewed in 1998-99 to ascertain any changes in oral health and utilisation of dental services. Data on socio-economic status, living arrangements and health behaviours will also be collected to determine whether any changes in those factors may explain changes in visiting behaviour and oral health. In addition participants will be asked to complete a questionnaire on satisfaction with dental care. Permission will be sought to gain access to participants School Dental Service records to determine whether any relationship exists between childhood visiting patterns and those in adulthood. This study will enable identification of the factors which affect oral health and dental utilisation in young adults to assist in the development of oral health promotion strategies to encourage timely, effective and appropriate dental service utilisation and preventive behaviours. To improve the oral health of Australians the maintenance of gains made in childhood is essential.Read moreRead less
The National Survey of Adult Oral Health will interview and dentally examine 7,500 people aged 15 or more across all States and Territories of Australia. It will provide a national snap-shot of the nation's oral health, including levels of tooth loss, dental decay and gum disease. The survey, to be conducted in 2004-04, will be directed by researchers at the Australian Research Center for Population Oral Health at The University of Adelaide.

It will provide a national snap-shot of the nation's oral health, including levels of tooth loss, dental decay and gum disease. The survey, to be conducted in 2004-04, will be directed by researchers at the Australian Research Center for Population Oral Health at The University of Adelaide. It will be conducted in collaboration with the Commonwealth and State-Territory health departments. Occurring 17 years after the first National Oral Health Survey of Australia, this new survey will monitor changes in oral health among all Australians. The survey will identify groups at particular disadvantage in terms of oral diseases, and it will search for lifestyle and community-level hazards that increase the risk of oral disorders. The study will have a compare patterns of dental health among people born before and after the fluoride generation of adults born in the 1960s when most of Australia's capital city water supplies became fluoridated. The study has been designed to automatically capture national statistics on general health among the 7,500 study participants over the next decade. The researchers will use that information to study links that have been observed in other countries between gum disease and heart disease. Results from the survey will provide the basis for monitoring progress towards national health targets and provide information to help direct dental health services into the 21st century.Read moreRead less
Explaining Social Inequality In Population Oral Health Using A Multilevel Approach

Summary
Our preliminary research demonstrated a social gradient in the oral health of Australian adults. Adults who occupy higher positions on the social hierarchy experienced less disease and symptom experience, enhanced quality of life, and better self-rated oral health. Not only were associations made between social position and oral health, but a range of other factors such as personal control, social support, stress, life satisfaction, and workplace and childhood social environments were also assoc ....Our preliminary research demonstrated a social gradient in the oral health of Australian adults. Adults who occupy higher positions on the social hierarchy experienced less disease and symptom experience, enhanced quality of life, and better self-rated oral health. Not only were associations made between social position and oral health, but a range of other factors such as personal control, social support, stress, life satisfaction, and workplace and childhood social environments were also associated with oral wellness. This work is new Australian research and is yet to be published. In an expansion of this project, we move from describing oral health inequalities and identifying their social determinants to provide a better understanding of pathways to population oral health. In doing so we shift the focus from the individual to the social context in which individuals live. We suggest that characteristics of social environments contribute independently to the variation in oral health outcomes accounted for by the characteristics of the residents themselves. In particular, we seek to demonstrate that social cohesion (the social integration, trust, and reciprocity within an area) influences conditions linked to oral health. Previous research has demonstrated variation in health according to area. Such studies are able to demonstrate a clustering of health, but are not able to distinguish whether observed social patterns in health reflect characteristics of residents or some feature of the area itself. Such conclusions require multilevel statistical models designed to separate individual effects from contextual effects while simultaneously examining interactions between both levels. Oral health is ideally suited as a proxy for general health because of the ubiquity of dental diseases, the broad utilisation of dental services within the population, and the shared risk factors between oral disease and a wide range chronic health conditions.Read moreRead less

Firstly, we want to learn how genetic and non-genetic factors influence the timing and sequence of emergence of primary (baby) teeth. Most children get their baby teeth between the ages of 6 months and 2.5 years, but sometimes they appear earlier, even at birth, and some children don't get all their baby teeth until about 4 years. By studying identical twins and non-identical twins we will be able to work out whether genetic factors are most important in determining this variation or whether other factors such as diet or illness also play a significant role. Secondly, we want to find out whether there is a relationship between the timing of emergence of the primary teeth and the growth of bacteria in the mouth that may lead to dental decay. It seems that the most likely source of the bacteria that can cause dental decay is a baby's mother and that children infected before three years of age are more likely to get dental decay subsequently. We will determine when decay-producing bacteria first appear in the mouth and check whether the same types of bacteria are present in twins and their mothers. This information will enable us to sort out whether the process that allows bacteria to become established around the teeth has a strong genetic basis or not. If we can gain a better understanding of how genetic and environmental factors influence dental development, we will be in a better position to manage individuals with altered tooth emergence that can lead to crowded teeth. Furthermore, if we can demonstrate a link between tooth emergence, growth of oral bacteria, and development of dental decay, we should be able to determine the most effective time to introduce preventive measures to control dental disease.Read moreRead less

Funding Amount
$345,184.00
Summary
Dental fluorosis is an important aspect of oral health because: perception and concerns about fluorosis influence perspective and success of fluoride programs; and advices on fluoride use are based on a risk-benefit tradeoff. This study is expected to report changes in fluorosis, its longterm impact and evaluate fluorosis and caries trade-off. This will be the first study of the natural history of fluorosis. Findings will have significance for individuals, dental profession and health policy.
Development Of Antimicrobial Peptides Targeting Oral Pathogenic Bacteria

Funding Amount
$663,350.00
Summary
The bacterial associated oral diseases; periodontitis and caries are major public health problems. The prevalence of these diseases and increasing bacterial antibiotic resistance has meant there is a need to develop new therapies. This project addresses this by modifying a novel class of antibiotics/antiseptics �antimicrobial peptides� to target oral bacteria and testing them using a newly developed screening method. This project will lead to new therapies for periodontitis and caries.
