Pulsed Laser Ablation Of Smear Layers In Root Canals
Funder

Funding Amount
$32,628.00
Summary
The project is in the general field of clinical dentistry, and in the speciality area of endodontics (root canal treatment). It examines the ability of several novel laser systems to remove bacteria and soft tissue debris from the root canals of teeth, building on recent developments in optical fiber technology and in antimicrobial therapy.
“Genetics, epigenetics, and the environment” is often used to describe a complex that results in the production of a phenotype; the latter two usually blamed with missing heritability. We know that the environment affects dental development and dental caries susceptibility, but we have little information about the precise molecular mechanisms linking the environment to observed phenotypes. This study interorgates the role of epigenetics in dental development and dental caries.
Impact Of Health Policy On The Delivery Of Dental Services And Child Oral Health Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$1,304,799.00
Summary
This project will study the use of dental services by children and adolescents in Australia and how use relates to oral health outcomes. Variation in the support for the use of private dentists and the organisation and delivery of school dental services will be compared both within and across all states and territories so as to inform policy discussions on how to best improve child oral health.
Minimally Invasive Approach To Manage Early Childhood Caries In Aboriginal Preschoolers
Funder
National Health and Medical Research Council
Funding Amount
$1,488,220.00
Summary
The treatment of dental decay in young children is often undertaken in a hospital, which is costly and risky. A treatment approach tested among a non-Aboriginal preschool population in WA, using hand instruments only and without the use of local anaesthesia, showed nearly a ten-fold reduction in the need for specialist dental care. This study will test the effectiveness of dental treatment of preschool children in rural and remote Aboriginal communities, using the alternative approach.
Determinants Of Inequality In Child Oral Health At School Age–A Prospective Cohort Study
Funder
National Health and Medical Research Council
Funding Amount
$1,229,853.00
Summary
This study aims to examine effects of socioeconomic circumstances as determinants of child oral health conditions, which can be mediated by dietary patterns, use of fluoride and dental service.
Understanding Influences On Oral Health Of Contemporary Australian Children
Funder
National Health and Medical Research Council
Funding Amount
$408,388.00
Summary
This study will contribute to an understanding of the factors affecting child oral health. Findings will have scientific value and relevance for the policy-making process in developing new methods of oral health prevention to target modifiable factors that will lead to improvement of oral health of children
Tooth Emergence And Oral Streptococci Colonisation: A Longitudinal Study Of Australian Twins

Funding Amount

Summary
We plan to include over 500 Australian families of twins in this 5-year study and to collect records of tooth emergence, cheek cells for DNA analysis, dental plaque samples for microbiological analysis, as well as other information from questionnaires. 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, ....We plan to include over 500 Australian families of twins in this 5-year study and to collect records of tooth emergence, cheek cells for DNA analysis, dental plaque samples for microbiological analysis, as well as other information from questionnaires. 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

With the aging of our population, issues concerning the lifetime of biological system are paramount to the quality of life and economic well being of our society. This project is closely linked to the development of prosthetic materials and structures that will improve performance and life of biomechanical devices, by providing better understanding to the mechanics of failure and failure origins of ceramic-based dental crowns and restorations, and to develop materials that will withstand exacting conditions - in body fluids - over extended lifetimes. Crown replacement is by far the most widespread of all prosthetic procedures. This project promises to help bridge the gap between physical and medical science in Australia. Read moreRead less
