4. Oral diseases in Australia Tooth and gum disease amongst most common causes of morbidity in Australia, and linked to negative effects on quality of life.[i] Oral diseases THE most common of the chronic diseases: important public health problems because of prevalence, impact on individuals and society, and expense of treatment.[ii] Yet, governments still separate oral health from general health and fund it quite limitedly.  [i] Spencer 1999, NSW Public Health Bulletin [ii] Sheiham 2005, Bulletin of the World Health Organisation 83 (9)

5. Current oral health trends in Australia The oral health of Australian children is generally good, currently ranking 2nd among Organisation for Economic Co-operation and Development (OECD) countries.[i] Dramatic improvements occurred between the 1970s and the 1990s, but a recent trend reversal has been documented. Overall caries experience rose between 1996 and 1999 among 6-year-old children, and there has been a 21.7% increase in decay among 5-year-olds.[ii]  [i] National Advisory Committee on Oral Health 2004. Healthy Mouths Healthy Lives: Australia’s National Oral Health Plan 2004-2013 [ii] Armfield et al. 2003. AIHW DSRU

6. Current oral health trends in Australia May not hold for all children. Evidence that most caries present in minority of children: 1997 Save Our Kids Smiles programme in NSW showed rural children significantly more likely to have dental caries than metropolitan.[i] Indigenous Australian children are also have significantly worse dental health than non-Indigenous groups. [1] [1] This and other ongoing research projects are detailed at: http://www.crroh.uwa.edu.au [i] AHS Health Status Profiles. NSW Health Dept.

7. Current oral health trends in Australia Dental health appears to deteriorate after childhood in all populations. 18–24 age group has poorer oral health than might be expected, given the low level of caries in children. This population has, on average, 7 teeth with caries cf 2 at age 12.[i]  [i] Brennan et al. 1997. AIHW DSRU

8. Current oral health trends in Australia This trend continues over time and adult oral health in Australia languishes behind that of many other developed nations. Dental caries represent the most prevalent health problem among Australians, and periodontal disease is the fifth most prevalent: 90% of tooth loss may be attributed to these two factors.[i]  [i] AHMAC 2001, cited in ADA submission to HoR Standing Committee on Health and Ageing 2005 ‘Inquiry into Health Funding’

9. Current oral health trends in Australia A monitoring survey of dental health among adult public patients, published in 2004 by the Australian Institute of Health and Welfare (AIHW), showed an overall drop in oral health status since 1995. Trends varied somewhat between patients from metropolitan areas and those from rural and remote locations.

10. Current oral health trends in Australia Oral health in Australia poor among adults, deteriorating among children. Most recent National Oral Health Survey conducted 1987/88, and results of a second survey not available for a further 3 years. Current evidence indicates those with worse teeth and gums tend to be public patients, often rural .

11. The major causes of morbidity and mortality [WHO] HIV Malaria Tuberculosis Malnutrition – under and over!! Tobacco Alcohol and other drugs Cancer Accidents War and violence

12. Important “Oral” Diseases Dental caries is variably active throughout the life span and is the major cause of tooth loss – excluding dentists!! Periodontal and peri-apical infections cause much morbidity and ?mortality Oro-pharyngeal cancers Mucosal diseases Salivary diseases and dysfunctions Developmental anomalies Maxillo-facial trauma

19. Prevention of Oral Diseases Oral diseases are lifestyle diseases – they are nearly all preventable. Both prevention and cure of dental and periodontal disease are important for overall health.

20. Interactions between oral and general health There are many studies to prove the link, for example, that periodontal disease is linked to cardiovascular illness. Stroke is more likely to occur with elevated levels of the periodontal pathogens Actinobacillus actinomycetemcomitans or Porphyromonas gingivalis.[i] Periodontal disease and tooth loss are linked to coronary heart disease (CHD)[ii] and there is specific evidence of an association between periodontitis and heart attack, even after adjusting for well-known risk factors.[iii] [i] Pussinen et al, Stroke. 2004;35:2020-3 [ii] Elter et al, J Periodontol 2004;75:782-90 [iii] Cueto et al, J Periodontal Res. 2005;40:36-42

21. Interactions between oral and general health There is some evidence that effective dental treatment of individuals with Coronary Heart Disease may result in reductions in levels of inflammatory markers (such as C-reactive protein) and haemostatic factors (such as oxidised low density lipoprotein), providing protection against future deterioration in heart health.[i]  [i] Montebugnoli et al, J Clin Periodontol. 2005;32:188-92

22. Public Funding Dental services are, however, almost entirely removed from medical services in Australia and many other parts of the world. Funding is provided separately, and there is a strong history of the Commonwealth Government deeming dental health to be a State/Territory issue. (This is despite the Commonwealth having the same constitutional powers [S. 51, xxiiiA] to fund dental services as it has for medical services.) There may also be an impression that, while medical services should at least in part be provided by Government, dental services are a matter for personal attention.

23. Public Funding While all States and Territories provide some public dental health services to individuals Who cannot afford to see a dentist privately, there is great variation across the country in this public provision of services.

24. Public Funding The Commonwealth Dental Health Program (CDHP) was introduced in January 1994 to improve access and reduce waiting times for public dental services by subsidising patients with concession cards to see private dentists for restorative dental treatment (denture services were not covered). The Commonwealth Dental Health Program drastically reduced waiting times for public dental patients. The Coalition Government discontinued funding for the CDHP at the end of 1996 and responsibility for funding the bulk of public dental services therefore passed to the State and Territory Governments.

25. Funding for Oral Health Services Total spending on dental services in Australia rose from $1.71 billion in 1992/93 to $4.37 billion in 2002/03 (4.9% versus 6.06% of total health expenditure).[i] [i] ADA submission to HoR Standing Committee on Health and Ageing 2005 ‘Inquiry into Health Funding’

26. Funding for Oral Health Services The Commonwealth Government’s proportional share of dental expenditure fell from 2.22% in 1992/93 to 1.78% in 2002/03. Indirect Commonwealth expenditure, through the 30% private health insurance rebate, was $298 million in 2002/03, representing 6.81% of total dental expenditure. The number of dental benefits has increased since the introduction of this rebate in 1999 from 14.4 million to 22.7 million in 2004. Costs of private health insurance are growing as a result, however, and benefits are reportedly not keeping up with dental care costs.[i]  [i] Private Health Insurance Administration Council 2005. Cited in ADA submission to HoR Standing Committee on Health and Ageing 2005 ‘Inquiry into Health Funding’

27. Funding for Oral Health Services State/Territory and Local Governments spent $342 million on dental services in 2002/03, representing 7.82% of total expenditure ($32 million less than in 1999/2000, when this funding represented 12.94% of total dental expenditure). This expenditure includes payments for public and school dental services.

28. Funding for Oral Health Services Over 15.5% of total dental spending was attributed to private health insurance funds in 2002/03, which is half the proportion of funds spent a decade earlier. Direct out-of-pocket expenses account for the remaining expenditure on dental services. This has risen from $984 million and 57.6% in 1992/93 to $2.96 billion and 67.3% of total expenditure in 2002/03.

30. Funding for Oral Health Services The Commonwealth Government contributes a relatively small amount to the provision of dental care (see Figure 3). However, it continues to fund dental care for specific populations, such as the Department of Veterans’ Affairs, Department of Defence, inpatient dental care and outpatient radiological dental services (through Medicare).[i]  [i] ADA submission to HoR Standing Committee on Health and Ageing 2005 ‘Inquiry into Health Funding’

31. Funding for Oral Health Services It also provides some indirect funding for dental services through the Aboriginal Health Council. Planned changes to Medicare include the provision of limited subsidised dental care for the first time for referred patients with chronic health conditions that are exacerbated by poor oral health. Up to 23,000 people may be treated over four years.

32. Funding for Oral Health Services All States and Territories fund the vast majority of public dental services, but spending varies significantly. According to the AIHW, in 2001/02 Queensland had the greatest expenditure ($111,000,000) and NT and ACT the least ($7,000,000). Per capita dental expenditure was greatest in NT ($35.23) and least in NSW ($11.76). Per concession card holder spend was also greatest in NT ($160.16) and least in NSW ($50.40).

34. Cost of Poor Oral Health Oral ill-health is not only costly in terms of personal discomfort; it is also expensive in economic terms. Dental decay is the most expensive diet-related disease in the country, costing more that Coronary Heart Disease, hypertension and diabetes,[i] and it may lead to hospitalisation: in 2002/03, 223 patients were hospitalised for dental conditions.[ii] [i] NSW Public Health Bulletin 1999 [ii] Steering Committee for the Review of Government Service Provision 2005, cited in ADA submission to HoR Standing Committee on Health and Ageing 2005 ‘Inquiry into Health Funding’

35. Access to oral health care Although supply of dentists in regional/remote areas is substantially lower than for major city areas, this does not automatically mean that people living in these areas access dental services less. Access to services may depend on car ownership, road conditions, and socio-economic issues. Although unmet demand and equity of access should be examined, lower rates of supply in rural and remote areas will indicate lower access. (See Teusner [i]).  [i] Teusner 2005 Australian Dental Journal 50:2

36. Waiting Times While waiting times in the public sector for emergency dental care are short throughout the country, waiting times for general dental care can be extensive (estimated to be between 10 and 54 months in 2000).[i] [i] AHMAC 2001

38. Dental Inflation Dental inflation is estimated at 20% - this is greater than the Consumer Price Index as well as greater than for other health services. (Mihailidis, S., Spencer, A.J. and Brennan, D.S. Perceived busyness and productivity of Australian private general dentists, Paper at IADR Conference, 25-28 September, Queenstown, New Zealand)

39. Demographics In the next ten years (10), 30% of the population will be over 60 years of age. A greater proportion of these people will have natural teeth. The destiny of our demography: from pyramid to … coffin? [Chairman Gary Banks, Productivity Commission, Policy Implications of an Ageing Australia: an illustrative guide (http://www.pc.gov.au/speeches/cs20050927/index.html) - presentation to the Financial Review Ageing Population Summit, held in Sydney on 27 September 2005]

40. Demographics These people will need, want and demand oral health care Function Quality of life Aesthetics Demand may not address inequality Role of technology Wanting youth Social marketing (Steele, J. 2005 Old is the New Young: A Changing world and research priorities, Paper at IADR Conference, 25-28 September, Queenstown, New Zealand)

42. Workforce to promote oral health Overall numbers of dentists per head of population appear to be increasing (to 46.9 per 100,000 population in 2000 from 43 in 1994). However, compared to other developed countries, Australia still lags behind in terms of dental workforce numbers.[i] It is difficult to project whether the rise will be sustained into the longer-term although there is no doubt that the number of dentists is low by historic levels. Numbers of dental graduates have fallen by one-third since the 1970s.[ii]  [i] Teusner, Spencer 2003. AIHW DSRU. [ii] National Advisory Committee on Oral Health 2004. Healthy Mouths Healthy Lives: Australia’s National Oral Health Plan 2004-2013

43. Workforce to promote oral health Significantly fewer dentists operate in rural compared to metropolitan areas (see Figure 6). Taking Australia as a whole, a comparison by the AIHW between rates of dentists practising in rural and metropolitan areas showed there are 55.7 dentists per 100,000 population in metropolitan areas and only 31.4 in rural areas in 2000. [i] In addition, rural dentists see more patients than their counterparts in the city.[ii]  [i] Teusner, Spencer 2003. AIHW DSRU. [ii] Barnard, White. Australian Dental Association News Bulletin 1999;266:13-21

45. Workforce to promote oral health Most dentists work in private practice. In 2000, 82.6 of dentists worked privately, with 16.2% in the public sector and 1.2% in other areas.[iii] [iii] Teusner, Spencer 2003. AIHW DSRU.

46. Workforce to promote oral health At the same time, the cost of studying dentistry is rising.[i] Currently, around 250 dentists qualify each year, but Spencer et al project that, in order to meet rising demand, an additional 120 dental graduates per year are needed across the country.[ii] Only 70 more Bachelor Degrees in Oral Health (for dentists, dental therapists and oral hygienists) have been funded by the Commonwealth Government from 2005.

56. Project One - Community Living Older People in South Australia Oral Health for older people and quality of life can be improved by integrating an oral health assessment within a general health assessment and providing timely dental care The whole process of design, implementation and evaluation is better done with oral health more fully integrated into the general health and aged care system.

58. Community Research Placement This course aims to provide the knowledge base, instil attitudes, and develop skills in research, practical health promotion and in preventative dentistry on a community level. It seeks to provide a balanced education in these branches of the health sciences whereby students appreciate the primacy of lifestyle and environment in determining population and community health, understand the many common risk factors for oral and general diseases and the importance of primary prevention in achieving both individual and population health

59. Community Research Placement Learning Outcomes At the end of Year 1, within the component included in Introduction to Clinical Oral Health Practice, students will be able to: Understand basic epidemiological principles Quantify the roles of common risk factors for oral and general diseases Know methods and indices for describing the common oral diseases, dental caries and the periodontal diseases, and describe variations in their severity and extent in different populations within Australia and the world Identify local and regional populations and communities with significant health needs which might be targeted for future community research placements

60. Community Research Placement Learning Outcomes At the end of Year 2, within the component Community Research Placement 1, students working in groups of 6-8 will have:

61. Community Research Placement Learning Outcomes At the end of Year 3, within the component Community Research Placement 2, students working in groups of 6-8 will have: Refined the oral health survey instrument from the previous year, based on the experience and data obtained Extended the oral health survey to improve the generalisability of the results and improve its power to address questions concerning causes of disease levels observed Devised a health promotion/health education programme for their community Performed basic preventative interventions such as fluoride applications and fissure sealants, under supervision, in a proportion of their population

62. Community Research Placement Learning Outcomes During Years 4 and 5, within the Community Research Placement 3 & 4 components of the Graduate Diploma in Dentistry, students working in groups of 6-8 will have revisited their communities from the previous years on at least two occasions and: Refined and extended their epidemiological surveys of oral health Extended the proportion of the population to which preventive oral health interventions have been applied Made a contribution, under supervision, to emergency dental interventions and pain relief in their community Carried out, under supervision, a range of dental treatments for patients in the community Written a detailed policy for promotion and maintenance of oral and general health for the future of their community Prepared information derived from their 4 or 5 years experience with their particular community for publication in the international refereed literature

63. Potential Communities Kindergartens, primary schools, secondary schools Tertiary teaching institutions Factories and other workplaces with a substantial on-site workforce Educational establishments for special needs, eg. Deaf, partially sighted, otherwise disadvantaged…. Hospitals, respite care, hostels and nursing homes

65. Conclusion Poor oral health is associated with significant costs in human and economic terms. Yet the main dental problems facing Australians are easily preventable. It is vital that the scale of the problem of dental and gum disease be recognised. The oral health workforce must be expanded and trained to promote oral health in order to reverse the trend in deteriorating oral health and ensure equality of care across the country.
