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

Nano-mechanical and nano-structural investigation of dentine: unravelling a novel nano-scale regulator of high durability of mineralised tissues. This project proposes that proteoglycans (PG) are key regulators of the high durability of dentine. PGs are primarily responsible for the structural organization of collagen in all vertebrates, however virtually nothing is known about their role on the biomechanics of mineralized tissues. This study aims to thoroughly address this question.

This project aims to examine the early effects of two recent initiatives by the Australian government to improve children’s dental health by providing funds to cover essential dental services for children from disadvantaged families. It explores the factors affecting eligible children’s access to benefits from these initiatives and identifies the causal impacts of these changed health care financing arrangements on children’s consumption of dental services, indicators of oral health and general health, and other indicators of cognitive and non-cognitive development. Using advanced econometric techniques and panel datasets, this project is expected to contribute to the development of effective policies for promoting health and wellbeing.Read moreRead less
