Summary
Particular immune cell populations (innate T cells), have a critical role in immunity. These cells are stimulated by bacterial cell wall components and are one of the first cells to appear after infection. We have shown that these innate T cells are stimulated by oral bacteria that cause the disease chronic periodontitis. This project will investigate how these innate T cells affect bacterial induced periodontitis and what role they play in disease outcomes.
A Multi-protein Vaccine Targeting The Oral Pathogens Associated With Chronic Periodontitis

Summary
Periodontitis is a chronic inflammatory disease associated with specific bacteria leading to the destruction of the toothÍs supporting tissues and ultimately tooth loss and is a major public health problem in all societies. Our research is focused on designing a vaccine that targets the major bacteria associated with periodontitis. We aim to produce a triple antigen vaccine and investigate the applicability of a vaccine administered under the tongue as an alternative to needle injections.
Sequencing Periodontal Bacteria To Determine The Relationship Between Periodontits, Renal And Vascular Function Among Indigenous Australian Adults With Chronic Kidney Disease

Funding Amount
$329,644.00
Summary
Almost 20% of Indigenous Australian adults exhibit signs of kidney disease. This study will investigate the relationship between sub-gingival (below the gum) bacteria and both kidney and artery function among Indigenous Australian participants with chronic kidney disease. Using an RCT design, the proposed study will investigate whether changes in sub-gingival bacteria and concentration following conventional treatment of periodontitis align with improvements in renal and vascular function.
Evaluation Of Tissue Engineered Decellularised Biphasic Constructs For Periodontal Regeneration

Funding Amount
$578,031.00
Summary
This project aims to regenerate the tissues lost as a result of gum disease. This will be done using scaffolds that replicate the complex structure of periodontal tissues.The scaffolds will be loaded with cells and allowed to mature before the cellular component is removed. The resultant construct is then inserted back into periodontal defects where it will be repopulated by host cells. This approach has the potential to be developed into an off-the-shelf clinical treatment.
Cementogenesis And New Periodontal Attachment Formation Using Cell Sheets

Summary
Periodontitis, a chronic inflammatory disease, affects 30-40% of the population and is a leading cause of soft and hard tissue destruction around teeth and tooth loss. Current treatment does not regenerate lost tissues resulting in inferior aesthetics and function. By using oral tissue engineered in the laboratory capable of supporting the growth and differentiation of cells necessary to achieve regeneration, the original structure and function of previously destroyed tissue may be restored.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Funding Amount
$831,955.00
Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.
Generation Of Induced Pluripotent Stem (iPS) Cells And Their Potential Use In Periodontal Regeneration

Funding Amount
$798,350.00
Summary
Dental diseases affecting the gums (periodontal diseases) are extremely prevalent. The effects of periodontal disease can be particularly severe as loss of support for the teeth leads to loose teeth and severely compromised chewing function. If left untreated, the associated loss of function may necessitate extraction of the teeth. We propose to generate induced pluripotent stem cells from gums and explore whether they can be used to restore periodontal tissues damaged by periodontal disease.
The Effect Of Titanium Surface Modification On The Immuno-regulation Of Osseointegration.

Funding Amount

Summary
Titanium implants are an established treatment modality in both dentistry and orthopaedics. This project will determine how implant surface modification can modulate the inflammatory response and subsequent differentiation of stem cells involved in the process of integrating the implant with bone i.e. osseointegration. The identification of the molecular mechanisms involved will thus provide leads for novel ways to further to enhance the osseointegration process and improve clinical outcomes.
A Study Of Various Bone Scaffolds In A Maxillary Sinus Model

Funding Amount
$61,711.00
Summary
This project investigates using animal derived and artificial bone in regions of the mouth that are deficient and not suitable for replacing missing teeth using dental implants. Traditional techniques of bone replacement require the use of a patient's own bone. These procedures are associated with post-operative morbidity and this bone is present in limited quantity. The use of these bone replacements may overcome these challenges and eliminate the need for using patient's bone.
How Are Periodontal Disease And Rheumatoid Arthritis Inter-related?

Summary
Periodontal (gum) disease and rheumatoid arthritis are two of the most common chronic inflammatory diseases affecting humans. These two diseases have remarkably similar patterns of tissue destruction. It is possible that chronic periodontitis may prime or predispose susceptible individuals to developing rheumatoid arthritis. Treatment of periodontal disease may help reduce the severity of rheumatoid arthritis.
