Learning on the country: Motivating dental students to attend a rural placement.

PURPOSE/OBJECTIVES: This research aimed to identify factors that affect dental students' attitudes toward participation in rural clinical outplacements (RCOP) in Australia, and to suggest strategies that will increase students' desire to attend RCOP in the future. METHODS: Dental students from the nine dental schools in Australia were invited to an online survey on their willingness to participate in an RCOP and the factors that influence this willingness. These factors were grouped into themes of education, personal and health, social, financial, and information-related. RESULTS: The study had an estimated response rate of 10% with 202 responses. More than two-thirds (68%) of students were willing to participate in an RCOP. Students who grew up in a rural area were significantly more likely to be willing to attend an RCOP, compared to those from urban settings. Attitudes toward the anticipated educational experience of RCOP were positive, while factors related to finances and pre-existing information were of concern to students. Educational, personal/health-related, and social factors had significant impacts on participants' willingness to attend RCOP. CONCLUSION: Overall, despite students holding negative opinions on certain social and financial factors, their positive attitudes toward other factors outweighed these. Universities should aim to further promote the educational benefits of RCOP to improve students' attitudes prior to attending RCOP. In-depth qualitative analysis is required to explore students' concerns regarding RCOP and longitudinal research is warranted to monitor students' attitudes toward RCOP and rural work over time.

Socio-economic status and access to fluoridated water in Queensland: an ecological data linkage study.

OBJECTIVES: To investigate the relationship between access to fluoridated drinking water and area-level socio-economic status in Queensland. STUDY DESIGN: Ecological, geospatial data linkage study. SETTING: Queensland, by statistical area level 2 (SA2), 2021. MAIN OUTCOME MEASURES: Proportion of SA2s and of residents with access to fluoridated drinking water (natural or supplemented); relationship at SA2 level between access to fluoridated water and socio-economic status (Index of Relative Socio-economic Advantage and Disadvantage, IRSAD; Index of Economic Resources, IER). RESULTS: In 2021, an estimated 4 050 168 people (79.4% of the population) and 397 SA2 regions (72.7%) in Queensland had access to fluoridated water. Access was concentrated in the southeastern corner of the state. After adjusting for SA2 population, log area, and population density, the likelihood of access to fluoridated drinking water almost doubled for each 100-rank increase in IRSAD (adjusted odds ratio [aOR], 1.93; 95% confidence interval [CI], 1.59-2.36) or IER (aOR, 1.77; 95% CI, 1.50-2.11). CONCLUSIONS: The 2012 decision to devolve responsibility for water fluoridation decisions and funding from the Queensland government to local councils means that residents in lower socio-economic areas are less likely to have access to fluoridated water than those in more advantaged areas, exacerbating their already greater risk of dental disease. Queensland water fluoridation policy should be revised so that all residents can benefit from this evidence-based public health intervention for reducing the prevalence of dental caries.

'You can't be what you can't see': equity, diversity and inclusivity of editorial teams of dental journals.

Introduction Equity, diversity and inclusivity in research is critical to ensure all of society contributes.Aim This study analysed the gender and location (workplace) of editorial teams across 124 dental journals.Methods All chief editors of the 91 dental journals listed on the journal citation report for 2021 were contacted to provide details of the numbers of chief editors, other editors and the editorial board members, plus a summary of their demographic information including gender, age (group) and location. If chief editors did not respond, publicly available information was collated for the analysis. The same publicly available information of 45 PubMed indexed journals not on the citation report and three emerging online journals was also retrieved.Results Of the 159 chief editors across the 124 journals, 131 (82%) were men and 30% were based in the USA. Of the 1,265 other editors, two-thirds were from the USA, UK, Brazil and Japan. Of the 3,044 editorial board members, half were from the same four countries.Conclusions 'You can't be what you can't see': women and people from many parts of the world cannot see themselves as chief editors, other editors or editorial board members of dental journals.

Biocultural Drivers of Salivary Microbiota in Australian Aboriginal and Torres Strait Islander Children.

Australian Aboriginal and Torres Strait Islander children experience unacceptably high rates of dental caries compared to their non-Indigenous Australian counterparts. Dental caries significantly impacts the quality of life of children and their families, particularly in remote communities. While many socioeconomic and lifestyle factors impact caries risk, the central role of the oral microbiota in mediating dental caries has not been extensively investigated in these communities. Here, we examine factors that shape diversity and composition of the salivary microbiota in Aboriginal and Torres Strait Islander children and adolescents living in the remote Northern Peninsula Area (NPA) of Far North Queensland. We employed 16S ribosomal RNA amplicon sequencing to profile bacteria present in saliva collected from 205 individuals aged 4-17 years from the NPA. Higher average microbial diversity was generally linked to increased age and salivary pH, less frequent toothbrushing, and proxies for lower socioeconomic status (SES). Differences in microbial composition were significantly related to age, salivary pH, SES proxies, and active dental caries. Notably, a feature classified as Streptococcus sobrinus increased in abundance in children who reported less frequent tooth brushing. A specific Veillonella feature was associated with caries presence, while features classified as Actinobacillus/Haemophilus and Leptotrichia were associated with absence of caries; a Lactobacillus gasseri feature increased in abundance in severe caries. Finally, we statistically assessed the interplay between dental caries and caries risk factors in shaping the oral microbiota. These data provide a detailed understanding of biological, behavioral, and socioeconomic factors that shape the oral microbiota and may underpin caries development in this group. This information can be used in the future to improve tailored caries prevention and management options for Australian Aboriginal and Torres Strait Islander children and communities.

Planning the oral health workforce: Time for innovation.

The levels and types of oral health problems occurring in populations change over time, while advances in technology change the way oral health problems are addressed and the ways care is delivered. These rapid changes have major implications for the size and mix of the oral health workforce, yet the methods used to plan the oral health workforce have remained rigid and isolated from planning of oral healthcare services and healthcare expenditures. In this paper, we argue that the innovation culture that has driven major developments in content and delivery of oral health care must also be applied to planning the oral health workforce if we are to develop 'fit for purpose' healthcare systems that meet the needs of populations in the 21st century. An innovative framework for workforce planning is presented focussed on responding to changes in population needs, service developments for meeting those needs and optimal models of care delivery.

Response of Salivary Microbiota to Caries Preventive Treatment in Aboriginal and Torres Strait Islander Children.

A once-annual caries preventive (Intervention) treatment was offered to Aboriginal and Torres Strait Islander schoolchildren-a population with disproportionately poorer oral health than non-Indigenous Australian children-in the Northern Peninsula Area (NPA) of Far North Queensland (FNQ), which significantly improved their oral health. Here, we examine the salivary microbiota of these children (mean age = 10 ± 2.96 years; n = 103), reconstructing the bacterial community composition with high-throughput sequencing of the V4 region of bacterial 16S rRNA gene. Microbial communities of children who received the Intervention had lower taxonomic diversity than those who did not receive treatment (Shannon, p < 0.05). Moreover, the Intervention resulted in further decreased microbial diversity in children with active carious lesions existing at the time of saliva collection. Microbial species associated with caries were detected; Lactobacillus salivarius, Lactobacillus reuteri, Lactobacillus gasseri, Prevotella multisaccharivorax, Parascardovia denticolens, and Mitsuokella HMT 131 were significantly increased (p < 0.05) in children with severe caries, especially in children who did not receive the Intervention. These insights into microbial associations and community differences prompt future considerations to the mechanisms behind caries-preventive therapy induced change;  important for understanding  the long-term implications of like treatment to improve oral health disparities within Australia.

Demonstration of high value care to improve oral health of a remote Indigenous community in Australia.

BACKGROUND: The oral health of Indigenous children in remote communities is much worse than other population groups in Australia. Providing and maintaining an oral health service is challenging due to the remoteness of communities, the associated high cost, and the low retention of clinical staff. An annual preventive intervention delivered by fly-in clinicians may be a more cost-effective way to manage this problem. In this analysis we estimate the cost-effectiveness of an annual professional intervention for the prevention of dental caries in children of a remote Indigenous community in Far North Queensland. METHODS: A cost-effectiveness analysis was conducted based on an annual preventive intervention protocol. This included treating all dental decay in those with disease, applying fissure sealants, a disinfectant swab, fluoride varnish and providing oral hygiene instructions and dietary advice to all participating school children. This study included an intervention group and a natural comparison group and both groups were followed-up for 2 years after the initial preventive intervention. A Markov model was built to assess the cost-effectiveness of the intervention compared with the usual care. Costs of treatment from the Queensland Department of Health were used and effectiveness was measured as quality-adjusted life years (QALYs) with the CHU-9D. One-way and probabilistic sensitivity analyses were conducted to identify key drivers and quantify uncertainty. RESULTS: The preventive intervention was found to be highly cost-effective. The incremental cost per QALY gained was AU$3747. Probability of new caries and seeking treatment were identified as the main drivers of the model. In probabilistic sensitivity analysis intervention was cost effective in 100% of simulations. CONCLUSION: An annual preventive intervention for remote Indigenous communities in Australia is a highly cost-effective strategy to prevent dental caries and improve the quality of life of children.

Epidemiology of facial fractures: incidence, prevalence and years lived with disability estimates from the Global Burden of Disease 2017 study.

BACKGROUND: The Global Burden of Disease Study (GBD) has historically produced estimates of causes of injury such as falls but not the resulting types of injuries that occur. The objective of this study was to estimate the global incidence, prevalence and years lived with disability (YLDs) due to facial fractures and to estimate the leading injurious causes of facial fracture. METHODS: We obtained results from GBD 2017. First, the study estimated the incidence from each injury cause (eg, falls), and then the proportion of each cause that would result in facial fracture being the most disabling injury. Incidence, prevalence and YLDs of facial fractures are then calculated across causes. RESULTS: Globally, in 2017, there were 7 538 663 (95% uncertainty interval 6 116 489 to 9 493 113) new cases, 1 819 732 (1 609 419 to 2 091 618) prevalent cases, and 117 402 (73 266 to 169 689) YLDs due to facial fractures. In terms of age-standardised incidence, prevalence and YLDs, the global rates were 98 (80 to 123) per 100 000, 23 (20 to 27) per 100 000, and 2 (1 to 2) per 100 000, respectively. Facial fractures were most concentrated in Central Europe. Falls were the predominant cause in most regions. CONCLUSIONS: Facial fractures are predominantly caused by falls and occur worldwide. Healthcare systems and public health agencies should investigate methods of all injury prevention. It is important for healthcare systems in every part of the world to ensure access to treatment resources.

The impact of a sugar-sweetened beverages tax on oral health and costs of dental care in Australia.

Background: Despite a clear causal link between frequent consumption of sugar-sweetened beverages (SSBs) and dental disease, little is known about the implications of a tax on SSBs in the context of oral health. The aim of our study was to estimate the impacts of a SSB tax on the Australian population in the context of oral health outcomes, dental care utilisation and associated costs. Methods: We designed a cohort model that accounted for the consequences of the tax through the mechanisms of consumer response to price increase, the effect on oral health due to change in sugar intake, and the implications for dental care use. Results: Our results indicate that in the adult population an ad valorem tax of 20% would lead to a reduction in decayed, missing and filled teeth (DMFT) by 3.9 million units over 10 years, resulting in cost savings of A$666 million. Scenario analyses show that the outcomes are sensitive to the choice of the time horizon, tax rate, price elasticity of demand for SSBs, and the definition of target population. Conclusion: We found that the total and per-person consequences of SSB tax were considerable, both in terms of dental caries (tooth decay) averted and dental care avoided. These results have to be compounded with the implications of SSB tax for other aspects of health and health care, especially in the context of chronic diseases. On the other hand, the improved outcomes have to be weighted against a welfare loss associated with introducing a tax.

Children's oral health in Australia: The past decade's research agenda.

OBJECTIVES: Research into dental diseases in children is no longer primarily focussed on biological and dietary factors, with social determinants an important influence. The aim of this study was to systematically review the focus of research on influences on children's oral health in Australia. METHODS: Relevant databases were searched for English language publications between 2008 and 2017. Included studies were original research articles with a focus on influences of oral health for Australian children. A thematic synthesis approach was adopted, and included studies were coded using the Fisher-Owens et al (2007) framework which included child-, family- and community level influences. RESULTS: A total of 252 studies were included in this review. The focus of the included studies was most frequently on child level influences (n = 200, 79.4%), followed by community level (n = 175, 69.4%) and family (n = 86, 38.1%)-level influences. Overall, the highest proportion of included studies were on the child level influences of physical attributes (n = 86, 34.1%) and child maturing (n = 83, 32.9%). The influences with the least number of studies were social environment (n = 2, 0.8%), social support (n = 3, 1.2%) and physical safety on both a family and community levels (n = 3, 1.2% and n = 1, 0.4%, respectively). DISCUSSION: Monitoring child level influences of oral health has consistently occurred in national surveys and epidemiological studies. Family level influences are comparatively underinvestigated and should be a focus of future research in Australia. This study has helped to identify area gaps in the literature and can guide future studies.

An assessment of endodontic treatment completion rate in a University-based student clinic and the factors associated with incomplete treatment.

Incomplete endodontic treatment is potentially a public health issue. The aim of this retrospective study was to evaluate the endodontic treatment completion rate at a University student clinic and to identify the factors associated with completion rates. The records of all patients who commenced an endodontic treatment (code 415) from January 2015 to December 2015 were extracted. A total of 783 records were available for analysis of which 86% received complete endodontic treatment. Maxillary first molars were significantly associated with incomplete endodontic treatment (IET). Patients requiring an additional visit (code 455) were 1.5 times more likely to have an IET. The endodontic treatment completion rate at the School of Dentistry at the University of Queensland is higher than those reported in other international university-based student clinics. Focus group surveys of students and supervisors are required to identify the reasons for higher IET with maxillary first molars and code 455.

Uptake and cost of influenza vaccines in a private health insured South African population.

BACKGROUND: Influenza vaccination is regarded as the most effective form of prevention and is particularly recommended for individuals at increased risk of developing severe influenza. Data on uptake (coverage) and costs in South Africa are limited. METHODS: This study examined influenza vaccination uptake amongst South African private health insurance scheme members. All claims received for services rendered in 2015 were collated at an individual level and the claims related to the provision of influenza vaccines were analysed. RESULTS: Of the almost 520 000 members, overall 5.0% (95% CI 4.9%; 5.1%) received the influenza vaccine in 2015. Priority risk groups such as pregnant women, older adults and those with a medical condition were significantly more likely to be vaccinated, as were members belonging to insurance schemes that offered a specific influenza vaccine benefit. The average cost of providing the vaccination was R350. CONCLUSIONS: Influenza vaccination coverage was low in this privately insured population. There were more members vaccinated in the priority risk groups. There is an urgent need to implement strategies to increase this coverage in privately insured South Africans.

The cost-effectiveness of oral health interventions: A systematic review of cost-utility analyses.

OBJECTIVES: To assess the usage of cost-utility analysis (CUA) in oral health interventions and to evaluate the methods used and the reporting quality of CUA in publications on oral health interventions. METHODS: A systematic review was performed on literature published between 2000 and 2016 where cost-utility analyses of oral health interventions were included. The reporting quality of these oral health CUAs was assessed against the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS: Of the 6637 publications identified initially, 23 met the inclusion criteria. Of these, 14 (61%) had been published in the last 6 years. Included studies were on oral cancer (n = 6), provision of dental prosthesis (n = 6), dental caries (n = 4), periodontal diseases (n = 3), antibiotic prophylaxis (n = 2), dento-facial anomalies (n = 1) and dental service provision (n = 1). Twenty-one studies were able to identify the most cost-effective intervention among the different options compared. Of the 23 studies identified, 15 (65%) used quality-adjusted life years (QALY) as the outcome measure, and 18 (78%) reported an incremental cost-effectiveness ratio. The economic perspective was clearly stated in 13 articles (57%). Twenty studies (87%) reported the discount rate, and 22 (96%) undertook sensitivity analysis. The reporting quality of studies, appraised by the CHEERS checklist, varied from 75% to 100% (median 92%). CONCLUSION: The use of CUAs in evaluation of oral health interventions has been increasing recently, especially from 2011 to 2016. The majority of CUA articles were of good reporting quality as assessed by the CHEERS checklist and were able to provide conclusions regarding the most cost-effective intervention among the different options compared: this will assist in healthcare decision-making and resource allocation. These positive outcomes of our study encourage wider use of CUAs within the dental and oral health professions.

Relationship between body mass index and dental caries in children, and the influence of socio-economic status.

OBJECTIVES: To determine the association of body mass index (BMI) with dental caries in Indian schoolchildren, and to analyse the influence of socio-economic status (SES). METHODS: The study population consisted of 11- to 14-year-old children from Medak District in Telangana State, India. The Indian Academy of Paediatrics 2015 growth charts were used to categorise children as underweight, overweight, normal or obese, based on their BMI. Data on the SES of the family were collected through questionnaires. Clinical examination for dental caries was performed by a single examiner. RESULTS: A total of 1,092 subjects returned questionnaires and were clinically examined (giving a response rate of 85%). There were no significant differences in caries prevalence and experience across the categories of BMI. However, caries prevalence and experience in overweight children were 24.8% and 0.69 ± 1.51, respectively, while the corresponding values in normal-weight children were 35% and 0.85 ± 1.50, respectively. Among children of high-SES families, overweight children had approximately 71% fewer caries than did those who were normal weight [incidence rate ratio (IRR) = 0.29; 95% CI: 0.11-0.78)]. CONCLUSIONS: BMI was not associated with dental caries prevalence and experience in this population. The association of BMI with dental caries varied across SES categories. In the high-SES category, overweight children experienced fewer caries than did normal-weight children.

Impact of dental National Partnership Agreements on public dental service waiting lists in Queensland.

OBJECTIVE: Analyse the Queensland Dental Public Service waiting list from 2013 to 2015 while various funding agreements between the federal and state and territory governments were in place. METHODS: Queensland Public Dental Service waiting list is open data and is updated monthly. This analysis reports on the changing number of people waiting for care and the percentage of people waiting beyond the reasonable period. RESULTS: While the number of people waiting decreased when funding was specifically allocated to "blitz the dental public waiting list", these have since increased back to pre-blitz period numbers. The percentage now waiting beyond the reasonable period has decreased from 57% to 28% over the study period. CONCLUSIONS: While the 'blitz' was successful in reducing waiting list numbers, this was not sustained. The deferred federal funding to states/territories for dental services may have worsened the situation. Implications for Public Health: While an injection of funds to reduce the waiting list is important and has had an impact, to adequately address oral health will require not just continuing funding, but also a shift away from the current curative 'downstream' approach towards a health-promotive 'upstream' approach. This will reduce not only the cost of treatment, but also waiting lists.

Inequalities in Tooth Decay in Australian Children by Neighbourhood Characteristics and Indigenous Status.

OBJECTIVE: Tooth decay is related to poverty, measured at individual and neighbourhood levels. It is however uncertain if living in an advantaged neighbourhood reduces tooth decay similarly in Australian Indigenous and non-Indigenous children. METHODS: This study describes tooth decay by neighbourhood characteristics and Indigenous status, and examines inequalities by Indigenous status. RESULTS: In deciduous dentition the percentage of children with tooth decay and untreated decay decreased on average 26% and 20% respectively in the non-Indigenous sample from poor to affluent neighbourhoods. In Indigenous children tooth decay and untreated decay decreased on average 6% and 8%, respectively, from poor to affluent neighbourhoods. CONCLUSION: While all children from affluent areas had less tooth decay, the gap between non-Indigenous and Indigenous children remained significant across neighbourhood characteristics. This suggests that both universal and targeted prevention programs should be considered for all Indigenous children irrespective of where they live.

An Investigation into Patient Non-Attendance and Use of a Short-Message Reminder System at a University Dental Clinic.

Non-attended appointments in health care facilities create inefficiencies and loss of clinical productivity: clinical teaching hours are reduced, impacting students' ability to meet the competencies necessary for professional registration. The aim of this study was to assess demographic and time-related factors for patient non-attendance at a dental school clinic in Australia. Appointment data were extracted from the patient management system for the years 2011 and 2012. Data included the status of appointment (attended, cancelled, or failed to attend [FTA]) and an array of demographic and time-related factors. Multinomial logistic regression was conducted to assess relationships between these factors and appointment status. Attendance rates were also compared by year following implementation of a short message service (SMS) reminder at the beginning of 2012. The results showed that, of 58,622 appointments booked with students during 2011 and 2012, 68% of patients attended, 23% cancelled, and 9% were FTA. The percentage of non-attended (cancelled or FTA) appointments differed by demographic and time-related factors. Females were 7% less likely to be FTA, those aged 16-24 years were five times more likely to be FTA, and early morning appointments were 18% less likely to be cancelled and FTA. With the SMS reminder system, the odds of a cancellation were 15% higher, but FTAs were 14% lower (both were statistically significant differences). This study found that failing to attend an appointment was significantly related to a number of factors. Clinical scheduling and reminder systems may need to take these factors into account to decrease the number of teaching hours lost due to patients' missing their appointments.
