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
The South Australian Dental Longitudinal Study has been the first comprehensive dental longitudinal study of older adults to be conducted in Australia. Participants were aged 60+ years at the 1991 baseline data collection, and were a random sample of community-dwelling older adults in urban Adelaide and rural Mount Gambier.

Participants were aged 60+ years at the 1991 baseline data collection, and were a random sample of community-dwelling older adults in urban Adelaide and rural Mount Gambier. The 11-year follow-up data collection will build upon the previous study findings to provide important and new information about the onset and progression of oral diseases in older Australians. It will also assist with the identification of general health and other characteristics (socio-demographic, medical, functional, cognitive, nutritional, swallowing, dental history, oral hygiene care, financial, social support and oral disorder social impact characteristics) that are associated with oral diseases in various groups of older adults. Groups of older adults within the study include those who are healthy and living in the community, those who are frail and use support services, and those who have moved into residential care. This information will assist both private and public health sectors, dental professionals and other health professionals with the identification of those older adults who are at high risk for developing oral diseases, such as those with dementia, those with physical disabilities, and those living in residential care. This 11-year data collection will be one of only 4 similar international studies currently being conducted, and will provide important comparison data for future studies of older Australians.Read moreRead less

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
Environmental, Socio-behavioural And Biological Predictors Of Early Childhood Caries: A Rural Birth Cohort Study

Summary
In Australia, up to 75% of children have dental decay at five years of age. It is substantially worse in rural parts of Australia, where fluoride is not added to the water supply. Also, the rate of caries increases as socioeconomic status decreases. This study aims to describe the natural history of dental caries from birth to 18 months. It will also examine the environment, behaviours and biology that these infants are exposed to.

It is substantially worse in rural parts of Australia, where fluoride is not added to the water supply. Also, the rate of caries increases as socioeconomic status decreases. This study aims to describe the natural history of dental caries from birth to 18 months. It will also examine the environment, behaviours and biology that these infants are exposed to. This data has never been collected before and will therefore provide a unique contribution to our knowledge and understanding of the development of dental decay in young children. This data is crucial for the development of interventions to prevent dental decay and address health inequalities. The study will examine infants teeth as they come into their mouths and collect questionnaire and saliva data from parents and infants following birth at 1, 6, 12 and 18 months. It is a partnership between the maternal and child health nurses of the western rural areas of Victoria (Ballarat, Ararat, Stawell and Horsham) and a national team of child health, dental researchers and statisticians drawn from the School of Health and Social Development at Deakin University, the Murdoch Children's Research Institute and The Royal Children's Hospital's Department of Paediatric Dentistry, The University of Melbourne, The University of Western Australia, Griffith University and the Queensland Government. The proposed study will make a substantial contribution to the understanding of early childhood caries by providing unique data on its natural history, the relationship between caries and risk and protective factors and the relative contribution of these factors to dental decay. Additionaly, it will include the latest measurement developments for quantifying microflora species and clinical caries outcomes. The comprehensiveness of this approach has been called for internationally, but has not yet been attempted.Read moreRead less
'An Investigation Of Aspects Of Oral Health And Access To Care For People Living In Social Chaos In The Rural Setting

Funding Amount
$57,036.00
Summary
Improving access to oral health care for disadvantaged populations is often difficult in the rural setting where workforce capacity is challenged by high demand for episodic care, lengthy waiting lists and absence of recall. For some people, lifestyles are not necessarily chosen or easily changed. Analyzing the stories people tell about their lives in the rural setting will offer explanations of how their doctors and dentists can effectively integrate their oral health and general health.

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
