Probing Developmental Causes Of Soft Tooth Enamel With Novel Mouse Models
Funder
National Health and Medical Research Council
Funding Amount
$470,112.00
Summary
Tooth decay is one of the most costly diseases in Australia and was recently called a national tragedy by the Prime Minister. The risk of decay increases if teeth don't harden properly in childhood. This project aims to clarify the causes of soft enamel and identify ways to prevent it. Two new test systems will be used to see how antibiotics and fluoride affect enamel hardening. Our findings will help the battle against tooth decay and guide the safe use of medicines in children.
Natural History And Longterm Impact Of Dental Fluorosis
Funder
National Health and Medical Research Council
Funding Amount
$345,184.00
Summary
Dental fluorosis is an important aspect of oral health because: perception and concerns about fluorosis influence perspective and success of fluoride programs; and advices on fluoride use are based on a risk-benefit tradeoff. This study is expected to report changes in fluorosis, its longterm impact and evaluate fluorosis and caries trade-off. This will be the first study of the natural history of fluorosis. Findings will have significance for individuals, dental profession and health policy.
Caries Initiation Across Childhood To Adulthood By Exposure To Water Fluoridation
Funder

Funding Amount
$198,297.00
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.
Understanding Influences On Oral Health Of Contemporary Australian Children

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
Is Non-invasive Management Of Dental Caries In Private Practice Cost-effective? A Randomized Controlled Trial
Funder

Funding Amount
$325,136.00
Summary
Despite evidence to the contrary, dentists routinely fill decayed teeth that, managed preventively, would be likely to repair (arrest). The probable cost to society of this approach is enormous. Modeling indicates that each new dental filling is likely to cost an average of $1811 (US) over the life-cycle of a tooth. This figure includes re-treatment costs, and the increased likelihood of more expensive re-treatment in future, such as root canal treatment and tooth crowning. An examination of the ....Despite evidence to the contrary, dentists routinely fill decayed teeth that, managed preventively, would be likely to repair (arrest). The probable cost to society of this approach is enormous. Modeling indicates that each new dental filling is likely to cost an average of $1811 (US) over the life-cycle of a tooth. This figure includes re-treatment costs, and the increased likelihood of more expensive re-treatment in future, such as root canal treatment and tooth crowning. An examination of the societal costs involved is likely to reveal this amount to be an under-estimate; consider the costs borne by sectors outside health: days lost to work, lost productivity. Further, we should consider costs to families: travel time and costs, childcare, the opportunity cost of items forgone in order to pay for the dental treatment. Despite this, a recent systematic review of dental caries prevention concluded 'there is presently no proof, in published economic evaluations of the cost-effectiveness of caries-preventive measures'. The authors highlighted a lack of methodologically sound studies. This research will compare a targeted preventive program to standard care within private dental practices. Prior to an alternative approach being introduced, an assessment of effectiveness and cost-effectiveness is needed. It is through such assessment that the value of the comparator can be assessed and our precious health dollars saved. The radical surgical approach (filling) that evolved to deal with the caries problem is entrenched in both public and private institutions that teach and deliver dental care. The strategic element is to reorient the services provided by general practices towards to goal of delivering a substantial reduction in the need to drill teeth, while maximizing the opportunity for a non-invasive remineralization approach that has been successfully demonstrated in in-vitro, in-vivo, and in small scale clinical trials.Read moreRead less
Dental caries (tooth decay) is initiated by demineralisation of tooth hard tissue by organic acids produced by dental plaque bacteria from dietary sugars. The disease is a major public health problem and has an estimated economic burden in Australia of over $1 billion p.a. being higher than that for any other dietary-related disease. We have discovered and patented a novel amorphous calcium fluoride phosphate that is stabilised by phosphopeptides from the bovine milk protein casein.

The disease is a major public health problem and has an estimated economic burden in Australia of over $1 billion p.a. being higher than that for any other dietary-related disease. We have discovered and patented a novel amorphous calcium fluoride phosphate that is stabilised by phosphopeptides from the bovine milk protein casein. These complexes, designated CPP-ACFP, have the potential to provide superior clinical efficacy in preventing dental caries and treating and repairing early stages of disease. The aims of this project therefore are (i) to develop topical formulations of CPP-ACFP for application to teeth to repair early stages of decay and (ii) to characterise the three-dimensional structure of the CPP-ACFP complexes. The significance of this work is that a superior and novel treatment for dental caries may be developed as well as providing insight into the structure of organically-stabilised amorphous calcium phosphate and its role in biomineralisation processes.Read moreRead less
The Common Risk Factor Approach To Assess Relationships Between Dental Caries And Adiposity In Disadvantaged Preschool Children
Funder
National Health and Medical Research Council
Funding Amount
$346,449.00
Summary
Dental decay and obesity in early childhood continues to be a significant health concern in Australian children. Current evidence suggests that these diseases are highly prevalent among children living in disadvantaged areas but the evidence of the relationship is limited. This increases their risk to carry the burden in adulthood. The present proposal uses a "common risk factor approach" to explore relationships between dental decay and obesity in disadvantaged preschool children in Australia.
Implementation And Sustainability Of Non-surgical Intervention For Dental Caries In General Dental Practice
Funder

Funding Amount
$390,388.00
Summary
Dentists in NSW and the ACT used new protocols to stop the spread of tooth decay. Many decayed teeth were then remineralised without the use of injections or drilling and filling. The process by which the dentists reorganised their practices to implement the protocols and how they explained them to their patients and practice staff will now be investigated to discover how best to promote their use Australia-wide. The sustainability and cost-effectiveness of this type of care will be measured.
