Exploring strengths and weaknesses in health services research culture and capacity.

Objective Fostering a research culture and enhancing research capacity within the workforce is essential for any health service aiming to provide evidence-based care. This study aims to explore the research culture and capacity in a community health service setting and provide a comparison to previous published research in other health service settings. Methods Participants were invited to complete a survey consisting of demographics and the Research Capacity and Culture (RCC) tool. Median and interquartile ranges were calculated for each RCC item and compared to three Australian and one international comparison. Results A total of 73 staff members from Metro North Community and Oral Health service participated. The team-level scores for the RCC were overall the lowest. Comparison to previously published research using the RCC indicated marginally higher scores for individual-level items in our study across all domains. Individual-level items were very weak to weakly correlated with the team and organisation-level RCC items. Strong to very strong correlations were found between a majority of the team and organisation-level items. Conclusions Team-level scores were substantially lower when compared to individual and organisational levels. The item 'team leaders that support research' was positively correlated with various organisation-level items, indicating that if the respondent perceived the team leader as a low supporter of research the respondent perceived several organisation items also poorly. As an important stakeholder in enabling research in a health service, organisations should investigate the challenges experienced by team leaders in facilitating research and the support or training they may need.

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.

Geographic patterns of dental service use in the Child Dental Benefits Schedule: 6 years of claims in the Longitudinal Study of Australian Children.

ISSUE ADDRESSED: This article explores the geographic patterns of claims within the Australian Government's Child Dental Benefits Schedule (CDBS). BACKGROUND: The CDBS is a means-tested schedule implemented in 2014 to improve access to dental services for children. Under the schedule, eligible children receive funding to subsidise dental services. METHODS: This study used data from the Longitudinal Study of Australian Children and linked data from the Medicare universal healthcare system, to examine dental service use amongst a subset of children aged 10 and 14 years. Dental service items were classified using Two-step Cluster Analysis, and appointments were analysed using multinomial logistic regression. Geographic characteristics were included as predictor variables. RESULTS: The study found that the majority of dental appointments were non-operative (70.7%, n = 5808), with diagnostic, radiographic, and preventive items being the most common. There were slightly higher proportions of operative appointments (fillings and extractions) compared with non-operative appointments in remote and very remote areas, low socio-economic areas, and Queensland and Northern Territory. Cluster analysis identified eight groups of non-operative appointments and four groups of operative appointments. New South Wales had a higher proportion of 'prophylactic IV' appointments than any other State and Territory, which included debridement and topical fluoride services. CONCLUSION: Cluster analysis identified distinct groups of non-operative and operative appointments, each with unique characteristics. The distribution of appointments varied by State/Territory and region. SO WHAT: Further research and interventions are needed to ensure equitable access to services and a shift to preventive care for disadvantaged populations of Australian children. Exploring alternative funding models that support clinically relevant claims, rather than maximising financial benefits such as time-based renumeration models should be explored.

Effectiveness of sensory adaptive dental environments to reduce psychophysiology responses of dental anxiety and support positive behaviours in children and young adults with intellectual and developmental disabilities: a systematic review and meta-analyses.

BACKGROUND: People with Intellectual and developmental disabilities (IDDs) experience oral health inequality due to myriad of risk factors and complex needs. Sensory processing difficulties, maladaptive behaviours and dental anxiety contribute to difficulties in receiving preventive and routine dental treatments. This study aimed to systematically review the evidence on the effectiveness of sensory adaptive dental environments (SADE) for children and young adults (up to the ages 24 years) with IDD to address cooperation and dental anxiety. METHODS: This review was reported according to The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. MEDLINE (Ovid), The Cochrane Library, Embase, Google Scholar, Web of Science and OT Seeker were searched using appropriate terms to identify Randomised Control Trails (RCTs) that matched inclusion criteria. Screening was conducted by two reviewers after de-duplication based on titles and abstracts followed by full text retrieval. Quality of the included studies was assessed using Cochrane Risk of Bias (ROB)-2 for crossover trials and data extracted by two reviewers. The details of the interventions and effectiveness were compared and discussed narratively, and comparable outcomes were included to meta-analyses using R software. RESULTS: A total of 622 articles were identified and five articles met eligibility for inclusion. Three studies used multi-sensory adaptations and one used single sensory adaptation of music. Narrative synthesis showed some evidence of SADE reducing magnitude and duration, although, questionable for reducing the number of maladaptive behaviours. Two studies demonstrated conflicting evidence of the effect of SADE on cooperation. Three studies demonstrated significant positive impact of SADE on psychophysiological outcomes. Despite an overall tendency to favour SADE, no statistically significant difference of maladaptive behaviours was found between SADE and regular dental environment (RDE) (Standardised mean change (SMC) = 0.51; 95% Confidence Interval (CI) -0.20 to 1.22; p = 0.161). SADE was superior to RDE (SMC -0.66; 95% CI -1.01 to -0.30; p = < 0.001) in reducing psychophysiological responses of dental anxiety. CONCLUSION: Current evidence suggests that adapting visual, tactile, and auditory aspects of the dental environment in a single or multi-sensory approach demonstrates small positive effects on psychophysiological responses and maladaptive behaviours of dental anxiety for people with IDD. TRIAL REGISTRATION: The title of this review was registered with PROSPERO (CRD42022322083).

Factors associated with suicidal ideation and suicide attempts by Australian dental practitioners.

INTRODUCTION: To investigate factors associated with suicidal ideation and suicide attempts amongst Australian dental practitioners. METHODS: A self-reported online survey of 1474 registered dental practitioners in Australia was conducted from October to December 2021. Participants reported thoughts of suicide in the preceding 12 months, prior to the preceding 12 months and prior suicide attempts. RESULTS: Overall, 17.6% reported thoughts of suicide in the preceding 12 months, 31.4% prior to the preceding 12 months, and 5.6% reported ever having made a suicide attempt. In multivariate models, the odds of suicidal ideation in the preceding 12 months were higher in dental practitioners who were male (OR = 2.01), had a current diagnosis of depression (OR = 1.62), were experiencing moderate (OR = 2.76) or severe psychological distress (OR = 3.58), had self-reported illicit substance use (OR = 2.06) or had previous self-reported suicide attempts (OR = 3.02). Younger dental practitioners had more than twice the odds of recent suicidal ideation than those aged 61+ years, with higher resilience having decreasing odds of suicidal ideation. LIMITATIONS: This study did not address help seeking behaviours directly related to suicidal ideation, so it is not clear how many participants were actively seeking mental health support. The response rate was low and results may be subject to responder biases, with practitioners experiencing depression, stress and burnout being more willing to participate. CONCLUSION: These finding highlight a high prevalence of suicidal ideation amongst Australian dental practitioners. It is important to continue to monitor their mental health and develop tailored programs to provide essential interventions and supports.

Parental recall bias in observational studies: Child dental service use.

BACKGROUND: Parents are frequently used to recall events of exposure and disease as a proxy for their children in observational health research. AIM: To assess the validity of parental recall of children's utilisation of dental services. DESIGN: Parents in the Longitudinal Study of Australian Children (LSAC) were asked to recall their children's overall dental service use in the previous year and whether the study child had received fillings or extractions due to decay in the previous 2 years. True positives were identified through parents who correctly recalled child dental service utilisation with actual dental treatment received in a linked dataset. RESULTS: Of the 10 090 participants from the LSAC, 1290 study children had linked dental treatment data eligible for inclusion in this study. The absolute true-positive rate for parental recall of dental service use in the previous year was 82% (n = 1263). Overall true-positive percentages were lower for recall of fillings (40%) and extractions (7%) in the previous 2 years. Increasing number of recall days was associated with the rate of true-positive recall adjusted for other factors in all three models. CONCLUSION: Accuracy of parental recall for tooth fillings and extractions was low. The use of parental recall for specific dental treatment over a time span of 2 years in further research is not recommended.

Health professionals delivering oral health interventions in early childhood: A scoping review of Australian and New Zealand literature.

ISSUE ADDRESSED: Dental caries is highly prevalent in very young Australian and New Zealand children. Health professionals other than registered dental professionals can help prevent early childhood caries, promoting oral health to assist families establish preventative oral health habits at a child's early age. This review identifies oral health promotion (OHP) delivered by nondental health professionals in Australia and New Zealand involving very young children. METHODS: Databases (MEDLINE, CINAHL, Embase, Emcare, Web of Science, Scopus, ProQuest, Google Scholar, TROVE) and digital libraries were searched between 2001 and 2021 for eligible studies and grey literature. Studies with a focus on preventative oral health strategies in a primary health care context were included. RESULTS: The review identified 76 studies. Seven met the inclusion criteria, and were conducted in Australia across metropolitan, rural, and remote settings. Studies that successfully engaged nondental health professionals to promote oral health to families reported a positive change in oral health practices among very young children. Delivering OHP during a child's early life stage positively influenced their oral health outcomes. CONCLUSIONS: Integration of dental and primary health care increased access to oral health care and advanced positive oral health outcomes for children. With adequate training, resources, and support mechanisms, nondental health professionals can deliver oral health strategies that facilitate behaviour change in parents to improve children's oral health. So What? Health promotion generates enabling conditions that support and empower families to improve and maintain their oral health. Nondental health professionals can play a crucial role promoting oral health for very young children and improving equitable access to preventative oral health care.

Has the Child Dental Benefits Schedule improved access to dental care for Australian children?

The Child Dental Benefits Schedule (CDBS) is an ongoing scheme administered through the Australian Government providing eligible children funding for clinical dental treatment. This study aimed to investigate the access of dental services across children's early childhood and examine whether the CDBS has improved access to dental care. The longitudinal study of Australian children is an ongoing cross-sequential cohort study with a representative sample of Australian children recruited in 2004. Birth (0-1 year) and kindergarten (4-5 years) cohorts were recruited through Medicare enrolment information at baseline and were representative of the Australian child population. Population-weighted longitudinal mixed effects Poisson models with individual identifiers as a random effect were used to assess the effect of Medicare dental schedules on reported dental attendance. Prior to the implementation of the CDBS for both cohorts, the birth cohort reported the lowest attendance rate at age 4-5. The introduction of the CDBS increased the rate of dental attendance for the low household income group by 8% (95% CI: 1%, 15%) after adjusting for confounders. The model provides evidence that dental attendance increased with age and the Indigenous population have 31% (95% CI: 4%, 55%) lower attendance rate after adjustment. The increase in reported access to dental services and favourable visiting patterns in low-income households during the operation of the CDBS provides some evidence that the schedule's primary aims to improve access to care in the child population are being met. Access to healthcare is multifaceted and the underutilisation of the schedule in the population warrants review of the schedule performance using other patient-centred indicators.

The use of consent forms in a "call from class" model of dental care for Australian Indigenous children.

ISSUES ADDRESSED: Dental caries is one of the most prevalent non-communicable diseases in children. Indigenous children reported a disproportionately higher prevalence of dental disease compared to their age-matched counterparts. To improve access to dental care a community-controlled service provides culturally appropriate dental services on the site of an Indigenous primary and secondary school. The dental clinic utilises a "call from class" model of care. Consent forms seeking permission to undertake a dental examination without a parent/guardian present during school hours are sent home. When the forms are returned, the student is located in class and a dental examination is undertaken. METHODS: A retrospective audit of dental records from 2019 and 2020 were undertaken. The number of consent forms sent and returned were recorded. RESULTS: In 2019, 87% (n = 220) of the school population were sent consent forms. Of the forms issued, 70% (n = 154) were returned. Almost all students required further treatment (90%, n = 137) and were sent a treatment consent form. Of the total student population, 67% (n = 171) were not seen or had outstanding treatment from unreturned forms. Proportions of incomplete treatment and unseen students were similar in 2020 (64%, n = 173). In this model, barriers are lessened by providing a free dental service on the school site. CONCLUSIONS: Consent is an ethical and legal necessity to undertake dental examination and treatment. Using physical forms were effective for gaining consent for most children. However, less than half of the school population's dental treatment was completed. Future studies should be conducted to explore the acceptability of using consent forms by parents/guardians and different models to gain consent for children from complex social circumstances.

Empathetic, persistent and female: A snapshot of oral health therapy students in Australia and New Zealand.

INTRODUCTION: Dental therapists, hygienists and oral health therapists constitute up to a third of the dental workforce in Australia and New Zealand. Personality is often explored in health professions to provide insights into traits that are conducive to workforce retention and to assist in planning and training. This study aimed to investigate the current demographic and personality characteristics of oral health students in Australia and New Zealand. MATERIALS AND METHODS: Students in years one to three of all eight undergraduate Bachelor of Oral Health programs in Australia and New Zealand were invited to complete an online survey. The survey measured activities prior to entering into oral health, career intentions and included a personality questionnaire, the Temperament and Character Inventory (TCI). RESULTS: Three quarters of participants (n = 336; 30% response rate; females = 90%) were single, from an urban area and 20-29 years of age. Oral health students overall portrayed high trait levels of Persistence and Cooperativeness. Cluster analysis of TCI traits identified three groups. Groups of students with high Persistence and Cooperativeness tended to be older, were working in non-dental and dental careers prior to their degree and were interested in working in regional areas after graduation. CONCLUSIONS: Students with high levels of persistence and cooperativeness were interested in working in regional areas after graduation, highlighting the importance of industriousness and persistence in overcoming barriers to practicing in regional areas. Further research is warranted to investigate barriers and enablers in recruitment and retention of males in a primarily female dominated profession.

Oral health: Epidemiology and concordance in Australian children and parents.

INTRODUCTION: Studying parent-child pair health provides the opportunity to identify risk factors and opportunities for oral health prevention and intervention focusing on the family context. The aim of this study was to describe the oral health of children aged 11-12 years and their parents in a national sample of parent-child dyads in Australia. METHODS: The Child Health CheckPoint is a study of 11 to 12-year-old children and one parent nested within the Longitudinal Study of Australian Children, a nationally representative cohort study. In 2015-16, the study collected two-dimensional photographic intra-oral images and was scored using visual assessments of the teeth, oral hygiene and malocclusion. RESULTS: Of the 1874 CheckPoint families, 1396 biological parent-child pairs had at least one oral health measure recorded. Over two-thirds of children had moderate to severe gingival inflammation (69.7%, 95%CI 64.7-74.9). Parents had a lower proportion of poor oral hygiene (2.1%, 95% CI 1.4-3.0) than children (13.0%, 95% CI 11.3-14.9). High concordance was seen in the Modified Gingival Index correlation coefficient 0.49 (95%CI 0.44-0.53). CONCLUSION: The high concordance in gingival health between child-parent pairs supports the familial and behavioural links established in previous studies. Children had poorer oral hygiene but fewer visible dental caries lesions than their parents. As dental caries is a chronic and cumulative disease, preventive interventions targeting children's oral hygiene are needed.

Understanding the well-being of dentistry students.

INTRODUCTION: The transactional model of stress is a framework describing the process for coping with stressful events as a relationship between the individual person and environment. This study aimed to investigate the associations between personality, learning environment and experiences of mental health for a cohort of Australian dentistry students. MATERIALS AND METHODS: Students were invited in 2017 to complete an online questionnaire including the Depression, Anxiety and Stress Scale (DASS-21), The Dundee Ready Education Environment Measure (DREEM) and Cloninger's Temperament and Character Inventory (TCIR-140). Students were followed-up one year later, and generalised estimating equations were used. RESULTS: A total of 219 (response 73.5%) students participated in the study. Two personality profiles of dentistry students were identified. Group 1 were significantly higher in the traits persistence, self-directedness, cooperativeness and reward dependence, whereas Group 2 were significantly higher in harm avoidance. Students with Group 2 personality had a 3.12 (CI:1.72-5.65) increased odds of depression compared to Group 1 students. Compared to students with positive perceptions of the learning environment, students with negative perceptions had increased odds of stress (3.48, CI: 1.85-6.53), depression (2.71, CI: 1.57- 4.65) and anxiety (2.59, CI: 1.56-4.28). CONCLUSION: Students with personalities high in levels of self-directedness, cooperativeness and persistence and low in harm avoidance, as found in Group 1, demonstrate high levels of general well-being. Positive perceptions of the dentistry learning environment were found to be an important influence on students stress. This study highlighted a number of factors important to student well-being and provides direction for further investigation of interventions aimed at enhancing student well-being.

SMS reminders to improve outpatient attendance for public dental services: A retrospective study.

Patients who miss scheduled appointments reduce clinical productivity and delay access to care for other patients. Reminders have improved attendance for healthcare appointments previously, but it is not known if short message service (SMS) implementation reduces incidence of patients unable to attend (UTA) or who fail to attend (FTA) appointments in the public dental service. This paper studied the effectiveness of SMS reminders in increasing appointment attendance at outpatient public dental services in Queensland. Data were sourced from the adult service and the children and adolescent oral health service (CAOHS) at West Moreton Hospital and Health Service, a public dental service in Queensland. A total of 63,238 appointments pre-implementation of SMS reminders and 55,028 appointments post-implementation over a period of 2 years were analysed for rates of attendance, UTA and FTA. Characteristics of UTA and FTA appointments were analysed to identify factors that hindered improvement after implementation of reminders. For the CAOHS, the attendance rate decreased 4% (95% CI: 2%, 6%) following SMS implementation. The UTA rate also increased by 20% (95% CI: 15%, 25%). Following SMS implementation in the adult service, the attendance rate increased from 73.5 (95% CI: 72.6, 74.4) to 77.7 (95% CI: 76.6-78.8) per 100 appointments. The FTA rate post-implementation was 1.08 (95% CI: 1.00, 1.16) times that from pre-intervention, and the UTA rate decreased from 21.7 (95% CI: 21.2, 22.2) to 17.1 (95% CI: 16.6, 17.7) per 100 appointments. The SMS reminders had a mixed effect on the attendance, UTA and FTA rates for the CAOHS and adult services. Reminders reduced the rates of UTA for the CAOHS service and increased the rate of attendance for the adult service. There was an increase in the FTA rate for both services.

The extent and nature of dental anxiety in Australians experiencing homelessness.

High dental anxiety is a major barrier to accessing dental care and has been found to be experienced to a greater extent in the homeless population. No studies have investigated the extent and nature of dental anxiety in Australians experiencing homelessness and was the aim of this study. Participants were recruited from four not-for-profit organisations in inner Brisbane using convenience and snowball sampling. The Dental Anxiety Questionnaire (DAQ) and the Index of Dental Anxiety and Fear (IDAF-4C+ ) questionnaire and oral health screening were completed by people experiencing homelessness in Brisbane, Australia, and compared to population norms. Descriptive statistics were calculated, and non-overlapping confidence intervals considered significantly different. The majority of the participants (n = 66) were male, a current smoker, unemployed and living in government supported housing. Most of the participants rated their oral health as poor/fair (n = 46, 71.9%) and their oral function as good or higher (n = 34, 53.1%). Using the single-item DAQ, 28.2% (n = 19) of people experiencing homelessness had high dental anxiety, compared to 16% of the general Australian population. The mean summed IDAF-4C+ fear module score was 18.02 (CI 15.60-20.43), which was significantly higher than the Australian population (µ = 14.40, CI 13.93-14.86). The highest mean score in the IDAF-4C+ stimulus module was feeling embarrassed or ashamed as anxiety inducing (µ = 2.27, CI 1.89-2.64) and was significantly different from the general Australian population (µ = 1.40, CI 1.33-1.47). The poorer overall self-rated oral health by the homeless population may induce feelings of embarrassment or shame, highlighting the differing psychosocial aspect to dental anxiety experienced by this population. Managing dental anxiety is needed to improve accessing to dental care for this population. Multidisciplinary care from social workers, mental health workers and dental practitioners may be beneficial in managing fear.

Exploring dental students' knowledge of HIV and attitudes towards saliva screening for HIV.

INTRODUCTION: Early detection of human immunodeficiency virus (HIV) allows antiretroviral therapy to commence, improving patient outcomes. Screening for HIV with saliva can be undertaken by dental practitioners. Research has found the procedure to be better accepted by patients than traditional blood testing. However, lack of knowledge and time constraints were identified as barriers to implementation for dental practitioners. This study aimed to explore dental students' knowledge of HIV and their attitudes towards implementing saliva screening for HIV in a dental setting. METHODS: Convenience sampling was used to recruit four focus groups of six to nine dentistry students from the University of Queensland. Participants also completed a questionnaire prior to the focus group. RESULTS: Thirty-three students participated in the focus groups. Students recognised their knowledge of HIV was limited, and 46% (n = 15) reported having treated a HIV-positive patient in the last year. Three key themes emerged from discussions; knowledge and experience of HIV; barriers and enablers; and scope of practice. Students identified stigma, lack of training, cost and time restraints as barriers to implementing saliva screening for HIV. Opinions varied on if screening was within a dental practitioner's scope of practice. CONCLUSIONS: Whilst students were open to conducting saliva screening for HIV, they identified prominent barriers limiting its implementation within a dental setting. Education on saliva screening for HIV, patient counselling and referral pathways could be integrated into dentistry curriculums to reduce these barriers. Further investigation is needed into the cost-effectiveness of implementing screening for HIV in a dental setting.

Family-Level Predictors of Australian Children's Dental Caries and Injuries.

Purpose: Fisher-Owens et al. described the diverse family-level factors influencing children's oral health, but few studies have investigated these relationships using longitudinal data. This study investigated the association between family and child oral health using the Longitudinal Study of Australian Children (LSAC), a cross-sequential dual cohort study. Methods: A total of 10,090 children were recruited at baseline, and seven waves of data are available. Children's parents or guardians reported experiences of dental caries and injury. Data were used to model family-level predictors with generalized estimating equations. Results: In the final model, predictors of dental caries over time were younger mothers (odds ratio [OR] equals 1.37, 95 percent confidence interval [95% CI] equals 1.01 to 1.87) and lower parental education (OR equals 1.24, 95% CI equals 1.10 to 1.39). Other significant factors were poor parental health, parents smoking, English as the main language, and Indigenous parents. Parents with consistent parenting styles protected against caries. Predictors of dental injury included socioeconomic status and parental age. Conclusions: This study highlighted a number of significant family-level constructs that predict dental caries and injury. Understanding the influence of family provides evidence to warrant investigation into tailored interventions targeting young mothers, common health risk factors, and parenting styles.

Depression, anxiety and stress in a cohort of Australian dentistry students.

INTRODUCTION: Dentistry students face a challenging academic and clinical curriculum that can result in depression and anxiety. While studies usually report sources of stress for dentistry students, there is less information on levels of stress. This study used the Depression, Anxiety and Stress Scale (DASS-21), to report perceived levels of depression, anxiety and stress in a cohort of Australian undergraduate dentistry students. METHODS: Students enrolled in years 1-4 of the Bachelor of Dental Science (Honours) program at The University of Queensland were invited to complete the DASS-21 using an online questionnaire. Students completed the same questionnaire 1 year later. RESULTS: At baseline, the mean DASS-21 scores for this cohort (n = 179; females = 56%) were in the normal range for depression (4.69, SD 3.87) and stress (5.50, SD 3.65), and mild range for anxiety (4.25, SD 3.21). Overall, 24% (n = 42), 44% (n = 78) and 11% (n = 20) of students had moderate or above levels of depression, anxiety and stress, respectively. At 1-year follow-up, DASS-21 scores were not significantly different. CONCLUSIONS: Dental students have higher levels of depression, anxiety or stress than the general population, indicating they may be at risk for greater psychological distress. The information from this study should guide curriculum and learning environment design, as well as interventions to support students through this challenging degree.

Oral and aural problems in Australian Special Olympics athletes.

BACKGROUND: Associations between oral and aural problems among children have been explored, but not among adults with intellectual disability (ID), where often, oral and ear pain can be difficult to diagnose. METHODS: Data included Special Smiles and Healthy Hearing screenings from two Special Olympics (SO) events held in Australia (2013-2014). RESULTS: The SO athletes had poor oral health with a high prevalence (56.8%) of gingival signs and unmet dental needs (66.9%). Over one-third (33.9%) had partially/completely blocked ear canals, over one-fifth (20.7%) had possible middle ear problems, and almost one quarter (23.8%) had some hearing loss. No associations between oral and aural problems were found in the small sample (n = 130) of SO athletes. CONCLUSIONS: Although SO athletes have unmet needs for both oral and aural health, access to appropriate hygiene care is an important preventive factor that athletes, families, and carers should be made aware of. Regular oral and aural screenings are recommended to identify problems early, because ability to communicate pain and discomfort can be different for this population. A larger sample of SO athletes with tooth and sextant level data could clarify the association between oral and aural problems in people with ID.

Oral health in the Longitudinal Study of Australian Children: An age, period, and cohort analysis.

BACKGROUND: Oral health policy and funding must be informed by well-designed studies which monitor oral health and the factors which influence it. AIM: This study aimed to analyse the oral health of the Longitudinal Study of Australia Children (LSAC). DESIGN: The LSAC is a dual-cohort cross-sequential study run biennially since 2004. Carer-report measures for oral health were measured across six biennial waves and included frequency of tooth brushing, dental service use, and dental problems since the previous wave. RESULTS: A total of 10 090 Australian children participated at baseline (birth [B] n = 5017 and kindergarten [K] n = 4983). Most carers reported that children brushed daily and had regular access to dental care. Increasing age was a significant predictor of dental caries, whereas no differences were observed between time periods and cohorts. Dental caries was more frequently reported than dental injuries. Caries was highest at age eight for the B (n = 1234, 30.5%) and K (n = 1355, 31.5%) cohorts. CONCLUSIONS: By the age of six, caries prevalence had already begun to climb despite the majority of carers reporting good oral health behaviours for their children. Early intervention in the prevention of dental caries is essential, as children appear to attend dental services when caries is already occurring.
