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.

Microstructural-Functional Effect of Silver Diammine Fluoride on Apatites. This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue.

This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue. The new biomechanical evidence on the underlying mechanisms, alternative protocols, delivery systems enable to optimise the treatment. The scientific insights into arresting/repairing damage processes will provide critical data for developing minimal intervention protocols for pediatric and geriatric populations.Read moreRead less
Quantification of the Remineralisation of Enamel. This project has three specific aims:
1. To quantify the ultrastructure and mechanisms of remineralisation of enamel using scanning and transmission electron microscopy.
2. To determine the mechanical properties of remineralised tissue and compare with those of sound enamel.
3. To develop an in-vivo optical fibre probe for monitoring and quantifying the changes of mineralised carious tissue during remineralisation.

3. To develop an in-vivo optical fibre probe for monitoring and quantifying the changes of mineralised carious tissue during remineralisation.
This project will enable patients prone to orthodontic induced root resorption to be identified and also to assist with validating repair of enamel tooth structure in a non-surgical manner. It is anticipated to result in the development of a novel fibre optic instrument with applications beyond dentistry.

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

Despite its importance and potential, ceramic additive manufacturing (AM) is facing significant challenge for its inherent material characteristics prone to shrinkage and fracture during fabrication process. This project aims to fill a knowledge gap by developing a new computational design framework for a commonly-used indirect AM process. It will address a range of AM issues, such as residual stress/distortion, cracks, and uncertainty in a nondeterministic context. The study is expected to establish novel design methodologies for ceramic AM with process modelling, robust/reliable optimisation, and fracture-based design. It will provide ceramic industry with a new framework for biomedical, aerospace and mechanical applications.Read moreRead less

This project will lead to far more detailed understanding of skull mechanics in our own lineage. Results will be of great interest to international scholars in both evolutionary and biomedical fields and help to establish a primary position for Australia in the rapidly expanding area of computer simulation of biological structure. Further development on our own established protocols for automated transfer of CT scan data into finite element models, which have already improved speed, accuracy and realism, will take finite element analysis to a point at which it can be more readily applied to evolutionary, biomedical and safety design questions.Read moreRead less
