Introduction: Australia is the sixth largest country (in area) in the world with a total area of over 7.5 million km² (3 million miles²). To date much of the research and policy activity in the dental workforce has been based on simple statistical analysis including practitioner-to-population ratios; however, risks are associated with the application of these types of ratios. This study examined practice-to-population (PtP) ratios as a measure of accessibility., Methods: Two states of Australia with a total population of about 8 million people were chosen for the study data frame-set., Results: General dental practice (n=3841) locations were mapped against population for each state and each suburb (n=3545) within each state. Practice-to-population ratios for each suburb differed by almost 40,000% (ranging from 1:52 to 1:20,100) with the greatest density of practices in the core of the capital cities - coincident with high wealth areas., Conclusion: The study found that PtP ratios in the context of workforce mal-distribution and geographic impediments to access is an important measure.

Australia is the sixth biggest (by area) country in the world, having a total area of about 7.5 million km(2) (3 million square miles). This study located every dental practice in the country (private and public) and mapped these practices against population. The total population of Australia (21.5 million) is distributed across 8,529 suburbs. On average about one-third of the population from each State lives in suburbs without practices and 46% live in suburbs with one to five dentists. Of those living within the study frameset, 86.6% live within 5 km of a private practice and 84.4% live within 10 km of a government practice. Australia's dental practices are distributed in a very uneven fashion across its vast area. Three-quarters of suburbs have no dental practice and over one-third of the population live in these suburbs. This research clearly identified that in a vast and uneven socio-geographically distributed country, service planning, if left to market forces, will end with a practice distribution that is fixed by economic drivers of scale and not that of disease burden. A more population health-driven approach to future design and construction of government safety net services is needed to address these disparities., (© 2013 FDI World Dental Federation.)

This study developed a Monte Carlo simulation approach to examining the prevalence and incidence of dental decay using Australian children as a test environment. Monte Carlo simulation has been used for a half a century in particle physics (and elsewhere); put simply, it is the probability for various population-level outcomes seeded randomly to drive the production of individual level data. A total of five runs of the simulation model for all 275,000 12-year-olds in Australia were completed based on 2005-2006 data. Measured on average decayed/missing/filled teeth (DMFT) and DMFT of highest 10% of sample (Sic10) the runs did not differ from each other by more than 2% and the outcome was within 5% of the reported sampled population data. The simulations rested on the population probabilities that are known to be strongly linked to dental decay, namely, socio-economic status and Indigenous heritage. Testing the simulated population found DMFT of all cases where DMFT<>0 was 2.3 (n = 128,609) and DMFT for Indigenous cases only was 1.9 (n = 13,749). In the simulation population the Sic25 was 3.3 (n = 68,750). Monte Carlo simulations were created in particle physics as a computational mathematical approach to unknown individual-level effects by resting a simulation on known population-level probabilities. In this study a Monte Carlo simulation approach to childhood dental decay was built, tested and validated., (© 2013 FDI World Dental Federation.)

This study aims to provide a comparative analysis of the Chronic Dental Disease Scheme (CDSS) and the Allied Health Profession (AHP) program as they related to the greater Enhanced Primary Care Scheme introduced by the Australian Government to manage patients with chronic and complex diseases. A retrospective analysis of data pertaining to Medicare items related to dentistry and the allied health professions were extracted from the Medicare Benefits Schedule database online, and formed the basis of this study. The highest proportion of services was provided in the state of New South Wales. There appears to be synergy in the utilisation of services with jurisdictions either overutilising or underutilising services. Costs to the Enhanced Primary Care Scheme under the CDSS model (fee for service) were up to 40 times more expensive compared with the AHP model (fee per visit). Costs and treatment associated with the CDSS experienced an increase of 13350% during the period 2007-08, coincident with an increase in subsidization. Reconstructive dentistry accounted for the majority of the increase. Gender disparities in dentistry were less distinct when compared with AHPs and were postulated to be due to males presenting with conditions that were more progressive requiring more invasive treatment. A comparative analysis indicates significant differences in costs, nature of treatment and the manner of remuneration between dentistry and the AHPs. A fee for service schedule as evidenced by the CDSS is dependent on the degree of financial incentive as indicated by patterns in utilisation over time. The amount of treatment considered necessary may be influenced by the level of subsidy with treatment that may not reflect disease management. The AHP model, which is based around a fee for visit schedule, is not without its deficiencies but has not experienced significant rises in cost compared with the CDSS.

Population-level research is an essential area of health with the potential to affect quality of life and the broader economy. There are excellent epidemiological studies that have improved health services, but traditional research requires a considerable investment. Although electronic technology has changed the practice of many industries with improved efficiency, its application to health is relatively new. Termed 'e-health', this emerging area has been defined by the World Health Organization as the use of information technology to support many aspects of health such as in administration and scientific information. However, not all professionals are convinced of its use. This paper presents a novel application of this emerging area to describe the benefit in data collation and research to support one of the most pressing issues in public health: oral health and policy. Using the Chronic Disease Dental Scheme as an example, a critical discussion of its benefit to population-level research is presented. The Chronic Disease Dental Scheme method of electronic administration has been shown to enhance research and to complement existing progress in health data linkage. e-Health is an invaluable tool for population-level dental research.

Objective: This study examines the cost effectiveness of a model of remote area oral health service., Design: Retrospective financial analysis., Setting: Rural and remote primary health services., Participants: Clinical activity data and associated cost data relating to the provision of a networked visiting oral health service by the Centre for Rural and Remote Oral Health formed the basis of the study data frameset. The cost-effectiveness of the Centre's model of service provision at five rural and remote sites in Western Australia during the calendar years 2006, 2008 and 2010 was examined in the study., Main Outcome Measured: Calculations of the service provision costs and value of care provided were made using data records and the Fee Schedule of Dental Services for Dentists. The ratio of service provision costs to the value of care provided was determined for each site and was benchmarked against the equivalent ratios applicable to large scale government sector models of service provision., Results and Conclusion: The use of networked models have been effective in other disciplines but this study is the first to show a networked hub and spoke approach of five spokes to one hub is cost efficient in remote oral health care. By excluding special cost-saving initiatives introduced by the Centre, the study examines easily translatable direct service provision costs against direct clinical care outcomes in some of Australia's most challenging locations. This study finds that networked hub and spoke models of care can be financially efficient arrangements in remote oral health care., (© 2012 The Authors.

Introduction: The aim of the study was to project hospitalisation rates for the surgical removal of impacted teeth across Australia, based on Western Australian statistics., Methods: Population data were obtained from the Australian Bureau of Statistics and were divided across Australia by statistical local area and related to a validated socioeconomic index. Every episode of discharge from all hospitals in Western Australia for the financial years 1999/2000 to 2008/2009 indicating an impacted/embedded tooth removal as the principle oral condition, as classified by the International Classification of Disease (ICD-10AM), was included in the study. Hospitalisation data were obtained from the Western Australian Hospital Morbidity Data System. Variables of age, place of residence and health insurance status were utilised for projecting the Western Australian rates across Australia., Results: The results of the study showed a definite rural-urban divide and the estimated age-adjusted rates were almost three times greater in the higher socioeconomic areas when compared to their poorer counterparts. The costs of the procedure were estimated to be approximately $60 million per annum across Australia., Conclusion: The findings of this study can be used to inform health policy to guide proper allocation of resources and target services for the benefit of the community especially those residing in rural and remote areas in a vast country like Australia.

Over the past twenty-five years, there has been a substantial increase in work-based demands, thought to be due to an intensifying, competitive work environment. However, more recently, the question of work-life balance is increasingly attracting attention. The purpose of this study was to discover the attitudes of the next generation of dentists in Australia to parenting responsibility and work-life balance perceptions. Questionnaires on work-life balance were distributed to all fourth-year students at three dental schools in Australia. A total of 137 (76 percent) surveys were completed and returned. Most respondents indicated that they would take time off to focus on childcare, and just over half thought childcare should be shared by both parents. Thirty-seven percent felt that a child would have a considerable effect on their careers. Differences were seen in responses when compared by gender. The application of sensitivity analysis to workforce calculations based around changing societal work-life expectations can have substantial effects on predicting workforce data a decade into the future. It is not just the demographic change to a more feminized workforce in Australia that can have substantial effect, but also the change in social expectations of males in regards to parenting.

Objective: To explore the effectiveness of oral hygiene care on plaque and gingival status of residents with dementia., Background: Oral hygiene and oral hygiene care has been reported to be poor among the institutionalised elderly with dementia. The severity of oral diseases has been shown to increase with the severity of physical and cognitive impairment related with dementia. Little research has been carried out on plaque and gingival status of elderly with dementia and the impact of disability related with dementia on oral health in residential aged care facilities (RACF)., Materials and Methods: A cross-sectional study of 205 elderly residing in RACF in Perth., Results: Forty-one percent of the residents in RACF had dementia. Sixty percent of the residents with dementia and 75% of the residents with an Activities of Daily Living Oral Health score of D were assisted with oral care. Mean plaques scores and extent of gingival inflammation were higher for residents in the DD and D subgroups and resident with dementia. Residents assisted with brushing had higher mean plaque score and more moderate gingival inflammation., Conclusion: Oral hygiene care status in residents with dementia was poor despite the fact that oral care assistance was being provided., (© 2011 The Gerodontology Society and John Wiley & Sons A/S.)

Objectives: New Zealand is a country with a relatively small population (4 million people) distributed unevenly over a relatively large land area. Adult oral health services in New Zealand are almost all delivered through a market-driven, private practice model and are funded directly by patient payments. Little attention has been given to the distribution of these services. This study reports the findings of a high-acuity examination of the distribution of private dental practices in New Zealand, using modern geographic information system (GIS) tools., Methods: A total of 1,045 private dental practices in New Zealand were geocoded. These dental practices overlaid 1,909 area units., Results: The highest practice: adult population ratios found in this study reflected the areas with the highest population densities of Maori and Pacific Islander people., Conclusions: Oral health has a substantial impact on health-related quality of life and the utilisation of dental care services can contribute to its improvement. As such, it is expected that access to care should be focused on the population groups with the highest degree of need. However, in a market-driven, mostly private practice model, such as that in New Zealand, available care is concentrated largely in areas of high socioeconomic status and in populations with lower levels of oral disease., (© 2012 FDI World Dental Federation.)

Background: A sustained program of research is an integral part of human-kind's efforts to improve oral health. In addition, dental research is a vital part of the development of a strong and prosperous dental education system and has been one of the three pillars of the higher education sector (Research, Education and Service) for a very long time., Aim: This study aims to examine the last 30 years of peer review published dental literature in both, Australia and India, and to define the trends in publication over that time., Materials and Methods: This study used the Pubmed database using a set of core dental words for the years 1980 to 2009. Detailed analysis of the year-by-year rates of publication was done using Microsoft Excel., Results: India is on a near exponential upward growth while Australia through the latter half of the last decade has been more stable in output. State-wise breakdown in both countries shows that the proportions are more consistent for Australia, but for India, a major number of publications can be traced to three states., Conclusion: It is expected that dental research in Australia will grow in the coming decade as the new dental schools embed their educational programs and mature to develop strong research profiles. However, India is becoming a significant force in the published peer review dental research literature, and is growing at a very rapid rate.

Over the last decade, there has been a significant increase in attention to the overall accountability of higher education in Australia, and this is expected to continue. Increased accountability has led to the need for more explicitly documented curricula. The curricula from ten health-related disciplines developed over the last five years in Australia were the basis of this study. Curriculum information modeling is an approach that allows for the dynamic nature of curricula since elements and their linkages can be moved about and reconnected into meaningful patterns. In addition, the models give disciplines and institutions the ability to effectively monitor curricula and draw comparisons in a more unified manner. Curriculum information models are an efficient innovation in the design and management of curricula in higher education and particularly in the health care disciplines. They rest on the principles of reusable elements and linkages independent of content that were first used in the design, construction, and maintenance of buildings. The translation of this approach to the higher education sector provides a higher level of interoperability of resources and a clearer pathway for content design within a curriculum.

The use of Qualitative Research (QR) methods are now getting common in various aspects of health and healthcare research and they can be used to interpret, explore, or obtain a deeper understanding of certain aspects of human beliefs, attitudes, or behavior through personal experiences and perspectives. The potential scope of QR in the field of dental public health is immense, but unfortunately, it has remained underutilized. However, there are a number of studies which have used this type of research to probe into some unanswered questions in the field of public health dentistry ranging from workforce issues to attitudes of patients. In recent health research, evidence gathered through QR methods provide understanding to the social, cultural, and economic factors affecting the health status and healthcare of an individual and the population as a whole. This study will provide an overview of what QR is and discuss its contributions to dental public health research.

Background: The Chronic Dental Disease Scheme (CDSS) is the first public dental policy in Australia to attract Medicare benefits for dental services., Aims: This study examines the utilisation of a new federal method of funding dental care in Australia and provides an insight into the implications of government dental programs. The program titled; Chronic Dental Disease Scheme, provided government-subsidised dental care for people suffering from a chronic medical condition., Method: A retrospective analysis of activity data using the relevant item numbers were extracted from the open source Medicare Benefits Schedule database (MBS) for years 2007-2009., Results: During the study period, a total of approximately five million dental services were provided. There was a disproportionate use of services between jurisdictions. The highest proportion (66%) of services was provided in the state of New South Wales (NSW) with Victoria second (22%). The adjusted value of care provided as a proportion of comprehensive examinations ranged from $1937 in the northern territory (NT) to $2900 in NSW. The value of care per dentist ranged from nearly $80 000 down to less than $1000 and the value of care per adult of the population ranged between $53 and $1 across Australia. The highest was always in NSW and the lowest always being the NT. Fixed prosthodontics (reconstruction) accounted for the significant costs associated with the program., Conclusion: The scheme has been utilised above its budget estimate with prosthodontics accounting for the majority of expenses. Treatment plans differed between jurisdictions. The increase in utilisation of the scheme was coincident with periods of increased in subsidy and remuneration and has been postulated to be a main driver for its utilisation rather than the improvement in chronic health.

Background: The aim of the study was to undertake a six-year analysis from 1999/00 to 2004/05, of the demographic characteristics of hospitalisations for the surgical removal of impacted teeth in Western Australia under general anaesthesia., Method: Data for the current analysis was obtained from the Western Australian Hospital Morbidity Data System (HMDS). Gender, age, indigenous status, place of residence, type of hospital admitted, insurance status, and Diagnostic Related Group (DRG) cost estimates for the procedure were analysed., Results: A total of 37.6% of all oral health-related hospitalisations in Western Australia over the six years were for the removal of impacted teeth. Admitted patients were predominantly females (58.8%) and very few Indigenous people were hospitalised (0.2%). The average age of patients was 21.4 years (sd=9.9). Metropolitan patients were hospitalised 1.5 times more than rural patients for this condition. The majority of patients were hospitalised at a private metropolitan hospital and were insured. The total cost of hospitalisation for this condition contributes to 27% of all the oral health condition-related hospitalisation costs., Conclusion: This study suggests that the hospital-based removal of impacted teeth in Western Australia is associated with factors such as indigenous status, age, gender and private hospital access along with insurance status raising interesting questions over the equity of provision of this service.

Introduction: Dental decay (caries) is a common condition affecting preschool children in Western Australia (WA). Severe dental decay can have significant consequences as indicated by previous data reporting decay as the fifth most common cause of hospitalisation among preschool children in WA., Methods: This study examined the prevalence and severity of decay in preschool children in rural and remote WA and considered some of the factors associated with these rates., Results: The study reports on the dental health of 253 children aged between 2 and 4 years within five rural and remote communities in WA. Over 40% of these young children already had one or more decayed teeth with 19% having severe early childhood caries (s-ECC) and 15% having already suffered toothache. The disease burden was far higher among Indigenous children, who comprised one-third of the study group, in comparison with the non-Indigenous children in the study. Among the Indigenous children, decay was far more widespread (69% had decay compared with 25% of non-Indigenous children), and was more severely experienced (34% had s-ECC) and 28% having suffered toothache (vs respective rates of 10% and 7% for the non-Indigenous children). Only half of the Indigenous children brushed their teeth on a daily basis and one-third had never brushed at all (vs rates for non-Indigenous children of 85% and 2%, respectively)., Conclusion: Action to improve the prevalence and severity of decay among this group of Indigenous children is linked with promoting core messages for good oral health. A systemic approach to addressing the needs of remote dwelling people, and in particular remote area Indigenous children, must include a sustained, evidence based, primary health focus that is inclusive of oral health.

Introduction: Western Australia (WA), Australia's largest state, consists of approximately one-third of the country's landmass and has a population of approximately 2 million people. However, over 85% of this population live in a handful of urban centres with the majority (1.6 million) living in the state capital, Perth. Healthcare provision in this complex environment is difficult and a clear understanding of the distribution of the population and health service suppliers is critical to understanding and addressing the problem. The vast majority (80% or more) of oral health care in WA is provided by private practitioners on a fee-for-service basis. Although previous studies have examined the macro-level distribution of dentists, this study utilized a high acuity examination to examine the distribution of private dental practices in WA, especially in rural and remote areas., Methods: Dental practice locations were collected from open access sources and geo-coded. Population data were obtained from the Australian Bureau of Statistics and divided by census districts. The Index of Relative Socio-Economic Disadvantage (IRSD) was aggregated to census district level. Population and socio-economic data were then geo-coded using ArcGIS v9 (ESRI; Redlands, CA, USA). With Perth primary post office used as a central datum point, a sequence of maps at differing magnification was overlayed with a grid of latitude and longitude lines, or graticules., Results: Of the 602 dental practices mapped, 75% were within 32 km of the Perth General Post Office, and 95% were within 256 km. In metropolitan Perth, fewer dental practices were located in areas that have residents of lower socioeconomic status and the density of distribution of these practices was greatest in the inner city region., Conclusion: This study highlights the complex nature of providing care to irregularly distributed populations in economic environments that are driven by factors not purely related to disease burden.

Objective: The aim of the study was to test the hypothesis that all Australians based on clinical need have equal access to health services for the removal of impacted teeth as hospital in-patients., Methods: Data for the current analysis were obtained from the Western Australian Hospital Morbidity Data System (HMDS) for the six financial years 1999/00 to 2004/05. All cases of in-hospital treatment for impacted teeth were analysed and then correlated with socioeconomic status, geographic location of the patients, place of primary residence, and age., Results: In-patient extraction rates are significantly higher in the 10- to 19-year-old and the 20- to 29-year-old age groups when compared to the other age groups. A young adult from a higher socioeconomic group is 4 times more likely to have an impacted tooth removed in a hospital than his or her counterpart from a lower socioeconomic group, which is significant. Similarly, people living in highly accessible metropolitan areas have a 3 times greater chance of being hospitalised for this procedure than those from the remote and rural areas., Conclusion: There are significant differences among different groups based on socioeconomic status and access to health services for in-hospital removal of impacted teeth, thus rejecting the hypothesis. This raises doubts over the nature of the procedure, considering that most patients are young, non-Indigenous, and live in metropolitan areas. This implies that some of the procedures seem to be elective and there is a need for introduction of guidelines in Australia for removal of impacted teeth, which could reduce expenditures significantly. However, further research is required in this area.

Objectives: The increase in demand for dental care over the next 10 years is expected to outstrip the supply of dental visits in Australia, resulting in an ongoing shortage of dental practitioners. As trends in medicine have shown, the greatest effect will be felt in rural and remote regions, where an undersupply of dentists already exists. It is clearly evident that it is important to provide strategies that will increase the recruitment and retention of practitioners in rural and remote areas. Previous research suggested an increased likelihood for health graduates to choose rural practice if they have a rural background, or were exposed to rural practice during their education. Short-stay (three to four weeks) placements for final-year dental students has been part of dental education in Western Australia for near on a decade., Methods: This paper reflects on the experiences gained from managing this placement program., Conclusions: Short-stay placements are a quality learning initiative but need a high level of planning and a clear vision to be effective., Implications: The key factors in ensuring sustainable, student centred learning is driven through a small core group of staff who have strong direct links with rural and remote communities, students and support providers. The integration of service, education and research goals have played a critical role in sustaining placements. The philosophy underpinning the rural placements needs to be clearly articulated and applied effectively in each step of their implementation and a highly focused customer-service driven implementation is required to make short-stay rural and remote placements effective.

Background/aim: While Australians are one of the healthiest populations in the world, inequalities in access to health care and health outcomes exist for Indigenous Australians and Australians living in rural or urban areas of the country. Hence, the purpose of this study was to develop an innovative methodological approach for predicting the incidence rates of jaw fractures and estimating the demand for oral health services within Australia., Materials and Methods: Population data were obtained from the Australian Bureau of Statistics and was divided across Australia by statistical local area and related to a validated remoteness index. Every episode of discharge from all hospitals in Western Australia for the financial years 1999/2000 to 2004/2005 indicating a jaw fracture as the principle oral condition, as classified by the International Classification of Disease (ICD-10AM), was the inclusion criterion for the study. Hospitalization data were obtained from the Western Australian Hospital Morbidity Data System., Results: The model estimated almost 10 times higher jaw fracture rates for Indigenous populations than their non-Indigenous counterparts. Moreover, incidence of jaw fractures was higher among Indigenous people living in rural and remote areas compared with their urban and semi-urban counterparts. In contrast, in the non-Indigenous population, higher rates of jaw fractures were estimated for urban and semi-urban inhabitants compared with their rural and remote counterparts., Conclusions: This geographic modelling technique could be improved by methodological refinements and further research. It will be useful in developing strategies for health management and reducing the burden of jaw fractures and the cost of treatment within Australia. This model will also have direct implications for strategic planning for prevention and management policies in Australia aimed at reducing the inequalities gap both in terms of geography as well as Aboriginality.

Aims: This study aimed to assess the temporal and spatial changes in the demand for general anaesthesia, relative to disease incidence, in 0-19-year-olds., Methods: Hospitalisation data were obtained from the Western Australian Morbidity Data System for the financial years 1999/2000 to 2004/2005, and principal diagnosis was obtained from every patient discharged from a public or private hospital. Hospitalisation data was correlated with socioeconomic status and the geographical location of primary residence., Results: In the public hospital sector, there were greater rates of people residing in Statistical Local Areas (SLAs) with decreasing accessibility to healthcare services utilising the option of treatment of dental caries under general anaesthetic (GA) compared to people living within highly accessible areas. In the private sector, children who resided in SLAs with the greatest access to healthcare facilities had a greater rate of being hospitalised for the treatment of dental caries under GA., Conclusions: The results demonstrated distinct patterns of trends in demand for general anaesthetic care among different SES groups and geographical location of primary residence. There was an overall emerging trend of increasing demand placed on public sector both among dental care users among high and low SES. Moreover, the results demonstrated the potential application of geographic modelling as a service planning tool for estimating the future demand for GA care for dental caries in addition to the timely need for focused attention on preventive services for early identification, prevention and control of dental caries among children.

Objective: To report differences and trends in oral cancer incidence by gender, age, indigenous status and area of residence and on mortality in Western Australia., Methods: Data were provided by Western Australian Cancer Registry. Oral cancer definition included ICD-O-3 codes C00C08. Age-specific, direct age-standardized rates and mortality:incidence ratios were computed with 95% confidence intervals., Results: The incidence and death rates of oral cancer accounted for 2.3% and 1.3% of all cancers respectively. Over 25 years, the male:female incidence ratio was 2.4:1. Eighty-eight percent of new cases were over the age of 40, peaking in the sixth decade of life. The incidence rates were 14.6 and 6.2 per 100,000 per annum in men and women respectively. Over 17 years, standardized mortality rates were less than 1 per 100,000 per year, with double the deaths in men. Mortality:incidence ratios for oral cancer were between 0.4 and 0.6 with the exception of lip., Conclusions: Cancer registries are the only reliable source of data for epidemiologic surveillance of cancer incidence and mortality. Results from this study are comparable with studies on oral cancer in Australia and globally.

In line with findings throughout Australia, rural, remote and Indigenous Western Australians suffer from a higher burden of oral disease and have less access to dental practitioners and care than their urban and non-Indigenous counterparts. With workforce projections indicating an increase in the shortage of dental practitioners, especially in rural and remote areas, the Centre for Rural and Remote Oral Health (CRROH) in Western Australia set out to establish a sustainable programme to service such increasingly disadvantaged populations. Via the vertical integration of education, service and research CRROH pioneered a sustainable model to deliver much needed oral health services to some of Western Australia's most remote areas, while primarily focused on addressing the oral health needs of Indigenous Australians. One of the key lessons from the programme has been the development of a strong clinical governance framework and a support network to sustain services in remote locations. This study offers one way to provide and sustain dental care for those most in need, yet largely left out.

A combination of the increasing costs associated with providing a complex clinical program and an ever-reducing education-based income finds dental schools throughout Australia continuing to face serious financial risk. Even more important is the growing workforce crisis in academic staffing faced in almost all dental schools as the impact of the widening gap between private practice incomes and academic remuneration takes effect. This study developed a model of core variables and their relationship that was then transformed into a mathematical simulation tool that can be applied to test various scenarios and variable changes. The simulation model was tested against a theoretical dental education arrangement and found that this arrangement was a commercially viable pathway for new providers to enter the dental education market. This type of mathematical simulation approach is an important technique for analysis of the complex financial and operational management of modern dental schools.

Australians living in rural and remote areas have poorer access to dental care. This situation is attributed to workforce shortages, limited facilities and large distances to care centres. Against this backdrop, rural and remote Indigenous (Aboriginal) communities in Western Australia seem to be more disadvantaged because evidence suggests they have poorer oral health than non-Indigenous people. Hence, provision of dental care for Aboriginal populations in culturally appropriate settings in rural and remote Western Australia is an important public health issue. The aim of this research was to compare services between the Aboriginal Medical Services (AMS)-based clinics and a typical rural community clinic. A retrospective analysis of patient demographics and clinical treatment data was undertaken among patients who attended the dental clinics over a period of 6 years from 1999 to 2004. The majority of patients who received dental care at AMS dental clinics were Aboriginal (95.3%), compared with 8% at the non-AMS clinic. The rate of emergency at the non-AMS clinic was 33.5%, compared with 79.2% at the AMS clinics. The present study confirmed that more Indigenous patients were treated in AMS dental clinics and the mix of dental care provided was dominated by emergency care and oral surgery. This indicated a higher burden of oral disease and late utilisation of dental care services (more focus on tooth extraction) among rural and remote Indigenous people in Western Australia.

Background/aim: There is little epidemiological research regarding dental trauma in Australia. Previous research has largely focused on specific sub-populations with data not necessarily applicable to a general rural Australian population. Studies from other countries have presented variable data and the relevance of their findings to the Australian setting is questionable. The aim of this study was to investigate the prevalence, causes and presentation of dental trauma in a large rural centre in Australia., Materials and Methods: A retrospective analysis was performed of the dental records of 323 consecutive patients who had attended a private general dental practice in Bunbury, Western Australia following an injury to their teeth and/or mouths during the period from May 2000 to December 2005 (inclusive). Injuries were classified using the Andreasen system (1994). Data analysis was carried out using spss software and Chi-Square tests were performed with the level of significance set at 5%., Results: There were 528 teeth injured and eight patients had only soft tissue injuries. Males (68.1%) significantly outnumbered females (31.9%) and the ages ranged from 10 months to 78 years. The highest number of injuries occurred in children and adolescents, specifically the 0- to 4-year age group followed by the 5- to 9-year age and 10- to 14-year age groups. Trauma was most frequently the result of falls, accidents while playing and participating in sports activities., Conclusions: The maxillary central incisors were the most commonly injured teeth in both the primary and permanent dentitions. Uncomplicated crown fractures were the most common injury followed by luxations and subluxations. No significant differences in frequency were reported for the different days of the week, the different months or seasons of the year. Only one-third of the patients presented for dental treatment within 24 h of the injury while the remainder delayed seeking treatment for varying times up to 1 year.

Objective: The oral health of Indigenous Australians, whether urban or rural, is significantly poorer than their non-Indigenous counterparts, and it would be expected that the oral health of rural and remote Indigenous Australians would be particularly poor, although the extent of this extra disadvantage has not been thoroughly documented. The aim of this study was to assess the oral health status and oral health needs in a sample of adult residents of selected towns and remote communities in the Kimberley region of North-west Australia., Design: A cross-sectional survey (dental examinations and oral health questionnaires) was carried out., Setting: Rural and remote communities in the Kimberley region of Western Australia., Participants: Adults in four selected communities., Results: The mean Decayed, Missing and Filled Teeth (DMFT) score for all participants was 9.8 (SD 8.3). The mean DMFT increased with increasing age. Only 7.3% of people were caries-free. A total of 13% of participants had periodontal pockets of 6 mm or more, and only 3% had no periodontal disease. More than a third (37%) of all participants had advanced periodontal disease. Only 21% of participants did not need any dental treatment., Conclusions: The oral health of Aboriginal and Torres Strait Islander people are listed as one of the priority areas of Australia's National Oral Health Plan. Based on the above results, oral health is clearly an important priority in the Kimberley.

For dental education to continue to grow in Australia, there is a need to understand the effect of new innovations and to reflect on the way the profession as a whole has adapted to the highly innovative environment that is modern dental education. The Australian Dental Council's (ADC) accreditation activities for undergraduate dental programs is one constant over the last ten years that can be used to provide some insight into the reactions of schools to threats and opportunistic solutions brought about by change. In this study, accreditation reports were analyzed to provide trends in the themes of accreditation findings over the last ten years. The hypothesis was that the themes emanating from the findings of accreditation will reflect changes over time as schools have adapted to the changing higher education environment. A total of 820 recommendations were collated from twenty-one reports. From the recommendations collated, a series of themes were identified; predominant themes included staff, external relationships, funding, structure, documentation, curriculum, and communications. No clear trends in terms of recommendations were noted over the study period, and themes remained fairly consistent over the years. The outcome of the study did not support the hypothesis that changing trends in accreditation recommendations over the last ten years would reflect changes in the environment in which education providers are operating.

The School of Dentistry in Western Australia developed a pregraduation intern year in which final-year students, having completed their didactic education, undertook a focused clinical experiential program (CEP) over an extended year. This program was implemented for the first time in 2002. The aim of this study was to identify the strengths and weaknesses of the curriculum as perceived by graduates and to compare the perceptions of those graduates who did the CEP to those who did not. A survey with questions based on the graduate outcomes of the dental school was mailed to all graduates from 2000, 2001 (did not complete CEP), and 2004 (completed CEP). The response rate was 66 percent (n=57) and included twenty-nine respondents who graduated before implementation of the CEP and twenty-eight who completed the CEP. Most respondents (80 percent) were in the twenty to twenty-nine age group, and there were slightly more males (53 percent). Learning outcome items with the highest mean scores were practicing universal precautions (4.2), behaving ethically (4.2), and demonstrating a satisfactory level of core dental knowledge (4.2). Practical skills outcomes with the highest scores were amalgam restorations (4.3), anterior endodontics (4.3), and single crowns (3.9). When comparing the respondents who did CEP (51 percent) with those who did not (49 percent), there were few significant differences. The general findings from this survey were that most graduates, whether completing the CEP or not, perceived themselves to be prepared, competent, and confident to practice as dentists and were most confident in managing problems that they most frequently encountered during training.

Anticipating the looming crisis in access to dental services in rural and remote areas, the Western Australian Centre for Rural and Remote Oral Health developed an undergraduate rural placement program to provide dental students of The University of Western Australia opportunities for direct experience of rural and remote practice during the final year of the undergraduate curriculum. The Rural, Remote and Indigenous Placement program started in 2002 and, to the end of 2005, had placed 78 final year dental students in supervised clinical practice in rural, remote or Indigenous practice. In this study, the evolution of the program (2002-2005) is described and student evaluation of the program is reported. While involved in the rural placement program, students were assessed by experienced dental practitioners and provided program evaluation. This structured feedback allowed continuous improvement of the program. Data from each year's graduates was also analysed to examine the question of influence of placements on practice location during the first 6 months after graduation. Although it will be many years before the effects of outplacement programs can be specifically attained, the evidence to date indicates that the program may be a valuable tool among the plethora of strategies being investigated to augment Australia's rural oral health workforce.

Graduating dental practitioners requires the mastery of a number of skills and a significant body of basic information. Dental education is a complex combination of didactic and physical skill learning processes. It is necessary to develop appropriate tools to measure student clinical performance to allow the provision of interventional strategies at the right time targeted at the right individuals. In this study, an approach to early intervention surveillance strategies was developed that is cost-effective, transparent, and robust based on mathematical predictions of student clinical achievements. Using a cohort of students' clinical activity profile, a polynomial pair was developed that represents the predictive function of low and high achieving students. This polynomial pair can then be applied to students to predict their final achievement based on their current status. The polynomial methodology is adaptable to local variation such as access to clinical facilities. The early intervention surveillance strategy developed in this study provides a simple, cost-effective, predictive risk assessment system that relies on data sets already collected in most dental schools and can be completed without the need for significant human intervention. The mathematical approach allows the focusing of educational support towards students that require the assistance, thus augmenting the better use of resources.

Objective: In this study an analysis was undertaken to determine: (i) the major factors that influence oral health professionals to practise in rural areas and determine practice location; (ii) what assists the professional oral health workforce to remain in rural practice; and (iii) what the main reasons are for leaving rural practice., Design: A postal survey was undertaken among all registered oral health professionals in Western Australia., Setting: Rural and remote Western Australia., Participants: Registered dental therapists, dental hygienists and dentists in rural and remote Western Australia., Results: Results indicated that there are various factors that attract people to rural and remote areas, other than financial incentives. Incentives to remain in rural practice include the need for professional development. The most common reason for leaving rural practice was to access children's educational facilities., Conclusions: This study emphasises that many factors contribute to recruitment and retention of dental professionals in rural practice. A broad integrated retention strategy is needed to address oral health workforce shortage issues in rural and remote Western Australia.

Objective: To identify and describe interacting domains that are present during undergraduate psychiatric teaching and impress on educators the roles of these domains., Conclusions: Undergraduate psychiatric teaching is an essential part of general family physicians' training and practice. Undergraduate students' exposure to psychiatry might be inadequate. Curricular goals, teaching and evaluation of students need to be aligned. Research and information technology can play a bigger role in teaching. Validation of patients, students and teachers during the teaching process is important, but not always emphasized. Educators should be aware of society's unwritten expectations, judgements and opinions of mental illness sufferers. Identifying and facilitating the various interacting domains during psychiatric teaching may contribute to better education in psychiatry, better retention of knowledge for students and an improved recruitment of students to a psychiatric career.
