The program will pursue the broad research theme adding value to oral health surveys . Over a period of five years, eight junior researchers will work on projects that enhance the value of six oral health surveys within the Australian Research Centre for Population Oral Health at The University of Adelaide. Projects will range from analysis of inflammation caused by periodontal (gum) disease in the Australian population, to evaluation of school dental services provided over the last 30 years. Team investigators will work on these surveys to tackle public health problems confronting four distinct dental generations of Australians: _1) people in the oldest tooth loss generation who have lost, on average, half of their natural teeth; 2) the amalgam generation of middle-aged adults who had unprecedented numbers of cavities that are now filled - treatment that requires extensive maintenance and repair; 3) the younger fluoride generation that has historically-low rates of dental decay; 4) and today s pre-schoolers among whom there is disturbing evidence that oral disease is becoming concentrated within the most disadvantaged segments of the population. Their work will improve the information base needed to promote oral health and prevent oral illness in the Australian population.Read moreRead less
Study Of The Relationship Of Oral Health And Oral Health Service Utilisation To The General Health Of Older Australian Men

Funding Amount
$471,564.00
Summary
The mouths of older Australians now are very different to those of previous generations. The prevalence of complete tooth loss is declining rapidly and this has enormous implications for dental services. This study will use the established Concord Health and Ageing in Men Project (CHAMP) as a platform to conduct a study of oral health and oral health service use in 800 older men. A major focus of the study will be the inter-relationships between oral health and physical and mental health.
Allostatic Mediators Of Socioeconomic Inequalities In Periodontitis Among Australian Adults

Summary
Periodontal (gum) disease is a significant cause of tooth loss among adults in Australia. Bacteria (germs) that stick to teeth in dental plaque are the primary cause of gum disease. However, the amount of damage caused to the gums depends heavily on the body's immune system which fights infection throughout the body. Like many other health conditions, gum disease occurs at a higher rate in people in a relatively low socioeconomic-position (SEP) compared to people from high SEP. Studies of other ....Periodontal (gum) disease is a significant cause of tooth loss among adults in Australia. Bacteria (germs) that stick to teeth in dental plaque are the primary cause of gum disease. However, the amount of damage caused to the gums depends heavily on the body's immune system which fights infection throughout the body. Like many other health conditions, gum disease occurs at a higher rate in people in a relatively low socioeconomic-position (SEP) compared to people from high SEP. Studies of other health conditions have shown that psychosocial stress (eg. job strain, financial stress) disproportionately affects people in low SEP groups. Stress, in turn, is known to alter the body's defense mechanisms, including the immune system, contributing to higher rates of conditions such as heart disease. Researchers have used the term allostatic load to describe this failure of the body's defense system under stress. Stress has also been suggested as a contributing factor in gum disease. This study will investigate whether this sequence of events producing allostatic load also plays a role in gum disease. We will study a random sample of 610 Australian adults from the full range of SEP backgrounds. We will ask them about their experience of daily stress, and measure their levels of gum disease and dental plaque. We will also collect samples of fluid from around their gums to measure quantities of two chemicals that indicate the activity of immune defense mechanisms in the gums. We will analyze these results to determine whether stress affects the body's responses to dental plaque, and whether that response accounts for differences in levels of gum disease between SEP groups. Results from this study will pinpoint the role of common bodily defense mechanisms in the development of gum disease. These results may help to identify sources of stress that, if controlled, could reduce rates of gum disease and other conditions affected by allostatic load.Read moreRead less

Summary
Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced a ....Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced at this stage of life than at any other stage before or after. This study proposes to look at how oral health in young adults in shaped by their experiences across childhood, adolescence and early adulthood. This approach is based on recent evidence that points to the importance to adult health of the early years of life. In this life course perspective, the poorer health of disadvantaged individuals is seen to result from ongoing and cumulative exposure to difficult and disadvantaged circumstances across their life course. This study will trace and follow up a cohort of almost 10, 000 South Australians for whom social, familial, economic and dental behavioural information was collected in 1991-92 when these individuals were aged from five to 15 years. Now aged from 19 to 29 years, these individuals will be invited to attend a dental examination and complete a survey that will provide information on health behaviours and life circumstances shown to be important determinants of general and oral health status. One purpose will be to explore reasons for the comparatively poorer oral health status of Australian adults. A second purpose will be to investigate the magnitude of socioeconomic inequalities in oral disease at different life stages. The findings will add to the knowledge of the etiology of oral disease and open up opportunities to develop new methods of oral health promotion based on the understanding of accumulated risk across the life course.Read moreRead less
