Summary
There has been a strong investment in the oral health of Australian children and their oral health has greatly improved. However, there are a number of indications that not all the gains in child and adolescent oral health are not carried through to the next life stage, adulthood. Somewhere in the intervening years, much of the gains in oral health invested in children and adolescents are dissipated.

However, there are a number of indications that not all the gains in child and adolescent oral health are not carried through to the next life stage, adulthood. Somewhere in the intervening years, much of the gains in oral health invested in children and adolescents are dissipated. Hence, the purpose of this proposed research is to document the nature, distribution and determinants of oral health among South Australian 29 year olds so as to identify points of intervention to maintain Australian's improved oral health further into adulthood. The specific aims of the research are to document the oral health of a cohort of 29 year olds describe their dental life history and key proximate influences on their oral health identify significant determinants of their oral health to compare the cohort with a representative SA sample of the same age. This project will approach some 3,763 29 year old adults who participated in earlier research as 13 year olds in 1988-89. It will also compare these adults with a random sample of 557 further 29 year olds from the SA Electoral Roll. Participants will be interviewed and then dentally examined, providing a range of key outcome measures on oral health status and explanatory factors from when they were 13 years old, their dental history and circumstances as 29 year olds. The research project is expected to provide detailed documentation of the prevalence and severity of oral disease and its distribution in an adult cohort, and exploration of the dental life history and current determinants of the oral disease observed. It is anticipated that the strength of hypothesised relationships of determinants will have direct policy implications.Read moreRead less
Low Strength Silver Fluoride Solutions As Clinically Effective Bacteriostatic And Cariostatic Agents

Funding Amount
$147,800.00
Summary
Scientific evidence indicates that low concentrations of silver are effective in countering bacteria involved in dental decay, and that solutions of silver fluoride are effective in stopping progression of dental decay. This study aims to determine the effectiveness of low strength silver fluoride solutions in the clinical management of dental decay in children. Such solutions may provide a simplified technique for controlling dental decay in populations which lack traditional resources
Fluoridation Of Water Supplies In Remote Indigenous Communities In The NT: Requirements, Feasibility & Cost Effectivenes

Funding Amount
$72,559.00
Summary
The project has two major objectives: 1) to identify Indigenous communities that are likely to benefit most from fluoridation of the water supply, and 2) to examine the feasibility and impact of introducing a small scale fluoridation plant into at least one community. The first will be achieved through accurately mapping natural levels of fluoride in the water supply of Indigenous communities across the Northern Territory, and examining the oral health status of children in these communities. Th ....The project has two major objectives: 1) to identify Indigenous communities that are likely to benefit most from fluoridation of the water supply, and 2) to examine the feasibility and impact of introducing a small scale fluoridation plant into at least one community. The first will be achieved through accurately mapping natural levels of fluoride in the water supply of Indigenous communities across the Northern Territory, and examining the oral health status of children in these communities. The second will be achieved by installing a fluoridation plant in one or more communities that have been lobbying for fluoridation of their water supplies, and monitoring the maintenance requirements and costs of the plant, and the changes in dental health status in school children over a period of two to three years.Read moreRead less
Exposure To Diesel Exhaust And Lung Cancer Risk In Australia

Funding Amount
$581,519.00
Summary
Exposure to diesel exhaust increases the risk of lung cancer. One in five Australians is exposed to diesel exhaust in the workplace. This project will provide an exposure-response relation between diesel exhaust and lung cancer based on Australia-specific data. We will also estimate the number of lung cancer cases due to diesel exhaust exposure in Australia. We will do this by studying all miners in WA in the last 15 years, by linking several databases that are available in WA.
Quantitiative Assessment Of Solar UV Exposure For Vitamin D Synthesis In Australian Adults

Funding Amount
$1,162,536.00
Summary
This research program will add significantly to our current scientific understanding of the dual health outcomes of UV exposure (Vitamin D and skin cancer) . This project is in line with Australia's R and D Priorities, in that it will result in direct and indirect social and economic benefits to Australia by applying the scientific knowledge gained through this research to develop public health initiatives to improve some of Australia's most significant and costly health problems.
The main purpose of this study is to understand how airborne fungi affect asthmatics who are allergic to them. Fungi or moulds release large numbers of spores into the air that are inhaled. In many cases fungal spores outnumber other particles that carry allergen, such as pollens or cat dander, by 100 to 1. This makes fungi the most common potential allergen in the environment. Fungi have been associated with respiratory diseases including fungal sinusitis, asthma, rhinitis, allergic alveolitis ....The main purpose of this study is to understand how airborne fungi affect asthmatics who are allergic to them. Fungi or moulds release large numbers of spores into the air that are inhaled. In many cases fungal spores outnumber other particles that carry allergen, such as pollens or cat dander, by 100 to 1. This makes fungi the most common potential allergen in the environment. Fungi have been associated with respiratory diseases including fungal sinusitis, asthma, rhinitis, allergic alveolitis and sick building syndrome. Largely due to their diversity and complexity, allergenic fungi have not been well studied and the ways in which individuals vary when inhaling spores is not known. Unlike other allergenic particles, it is unlikely that fungal spores release their allergen as soon as they are inhaled because we have shown in earlier in vitro studies that fungi continue to release allergen over time and this is likely to be the case when they are inhaled. Our laboratory has developed two new techniques that allow us to measure how many spores people inhale and whether they are allergic to them. This study will use these tools to detect and identify the important allergenic fungi involved in domestic and outdoor exposure of asthmatics, the degree of contribution to the total allergen load to which subjects are exposed and identify in what conditions fungi are the causal agents in location-specific symptoms. This study will also investigate allergen production of fungi in situ in the human nose, which will have application in allergic sinusitis and asthma amongst other respiratory diseases. We will investigate how readily allergenic spores germinate in the nose and under what conditions they release allergen.Read moreRead less
