Summary
Bisphosphonates are used in patients with bones that break easily due to conditions such as osteoporosis. Recent research suggests a possible association between these drugs and jaw bone breakdown called jaw osteonecrosis - a devastating condition with no current effective treatment. It is unclear why this condition affects only jaw bones. This study seeks to investigate if bacteria in the mouth, gum disease and saliva are involved in jaw osteonecrosis, which can then help to improve management.
The CCRE for Oral Health will focus on the prevention and treatment of oral diseases and disorders and their clinical consequences. Research will emphasise three areas of clinical care that are critical to the management of oral health, systemic health and general well-being: 1.Primary prevention to prevent disease onset 2. Diagnosis and risk prediction for oral conditions 3. Clinical intervention

Summary
This research program is expected to contribute to filling significant gaps in the understanding of factors determining the oral health of Australian children and young adults. The purpose of the project is to develop a better understanding of the outcome of long-term exposure to fluoridated water among young adults.
A Multiple Antigen Lipophilic Adjuvant Carrier (MALAC) System

Summary
We have developed a Multiple-Antigen-Lipophilic-Adjuvant-Carrier (MALAC) system, based on the incorporation of lipoamino acids into a poly-functional core that provides an excellent means for enhancing the antigenicity of a potential peptide vaccine. A system is used for generating antibodies without the use of any conventional adjuvant. The system comprises two or more different antigens and one or more lipid anchor. The key of this system is a novel carrier construct, which is non-toxic and no ....We have developed a Multiple-Antigen-Lipophilic-Adjuvant-Carrier (MALAC) system, based on the incorporation of lipoamino acids into a poly-functional core that provides an excellent means for enhancing the antigenicity of a potential peptide vaccine. A system is used for generating antibodies without the use of any conventional adjuvant. The system comprises two or more different antigens and one or more lipid anchor. The key of this system is a novel carrier construct, which is non-toxic and non-immunogenic. The system contains variables, which allow optimising its structural configuration. A small library of poly-functional MALAC system will be synthesised in a controlled step-by-step way combining solution or solid phase techniques, where the exact chemical structure (and the order of the different immunological peptide sequences) of the construct is pre-determined. The antigenicity and the protection against disease will be compared with antigenicity and protection generated using conventional vaccine carriers. We also aim to exploit the particulate-forming properties of the lipo-peptide amphiphiles, to form micro-particulate oral antigens, exploiting the phenomenon of particulate uptake from the GI tract by the GALT or other intestinal sites. The MALAC constructs will be administered orally followed by the measurement of the serum IgG. Vaccination via the oral route is highly desirable, since it can overcome many of the disadvantages inherent in administration by injection - e.g. poor patient acceptability, requirement of skilled medical personnel, risk of HIV and other blood-born diseases, restricted availability and sometimes, stimulation of the wrong type of immunity. Development of vaccines for oral administration make them much more widely available, permitting self-administration and improving the operation of Public-Health vaccination programs, particularly in developing countries.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. 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 ....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. 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
