A qualitative meta-synthesis of carers' perceptions of factors influencing preschool children's oral hygiene practices-A social practices perspective.

OBJECTIVES: This study comprises a synthesis of published qualitative studies from developed countries on the perspectives of carers regarding the oral hygiene toothbrushing practices of preschool children, through the lens of social practice theory. METHODS: A search of the following electronic databases was conducted for all available years: MEDLINE, EMBASE and Global Health using the Ovid platform; Dentistry & Oral Sciences Source (DOSS), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus. Included qualitative studies reported primary caregivers' perceptions of oral hygiene practices (focusing on toothbrushing) in preschool children (0-5 years old) in developed countries. A thematic synthesis of the qualitative findings was undertaken for the results of each study. RESULTS: Eleven articles were included in this meta-synthesis. The focus of this paper was toothbrushing practices. A conceptual map of toothbrushing as a social practice was developed. Key findings included practice elements (meanings, competences, and materials), spatial and temporal aspects, and barriers and facilitators to performance. CONCLUSIONS: The application of a social practice lens to published qualitative research on the oral hygiene of preschool children provided insights into the meanings and competences related to toothbrushing, as perceived by primary caregivers. However, it also revealed limited information on material, spatial and temporal aspects of toothbrushing practices, indicating the importance of considering social practice theory as a framework in future research to address this gap. Furthermore, exploring toothbrushing in connection with related social practices has the potential to increase understanding of factors influencing oral health in preschool children.

Supporting the oral health of people with intellectual disability: A survey of disability staffs' knowledge, perceptions, disability service barriers, and training.

BACKGROUND: People with intellectual disabilities experience poorer oral health outcomes, which can negatively impact their quality of life. Disability support staff who support peoplewith an intellectual disability have the potential to assist with oral hygiene. However, there is limited understanding of the current practices of disability support staff around oral health, particularly in Australia. OBJECTIVE: To describe disability support staff knowledge about oral health, explore their practice perceptions when supporting people with intellectual disabilities around oral health and their experiences of oral health training. METHODS: A national cross-sectional survey was undertaken with 156 disability support staff across Australia. Recruitment was via publicly available websites of disability services and social media. RESULTS: Disability staff were generally knowledgeable about appropriate oral hygiene practices and risks to oral health. They were less knowledgeable about the links between poor oral health and chronic diseases (<40%) and the importance of oral care for individuals who are fed enterally. Most participants (>80%) felt oral health was an important part of their care and were interested in further oral health training. Staff in semi-assisted living felt they had more time for oral health tasks compared to home-based living and residential facilities (p = 0.007). Lack of oral health training programs was the main barrier cited (44%), with only a quarter receiving any training in this area. CONCLUSIONS: Disability support staff are receptive to promoting oral health. More training around oral health and intellectual disability is needed for this workforce to support them in undertaking this role.

Modeled health economic and equity impact on dental caries and health outcomes from a 20% sugar sweetened beverages tax in Australia.

Dental caries is the most prevalent oral disease across the life course. This study modeled the population health and economic impact of a 20% sugar sweetened beverages tax (SSB) for preventing dental caries compared to no intervention (societal and healthcare perspective). A cost-effectiveness analysis according to quintiles of area-level socioeconomic disadvantage was performed for the 2020 Australian population (0-100 years old) using a closed cohort Markov model. A qualitative assessment of implementation considerations (e.g., acceptability, equity, sustainability) was undertaken. Health outcomes were modeled as decayed teeth prevented and disability-adjusted life years (DALYs) averted. The 10-year and lifetime scenarios were modeled with probabilistic sensitivity analysis (Monte Carlo simulation, 2000 cycles). The 10-year scenario from a societal perspective yielded cost-savings of AUD$63.5M, healthcare cost-savings of AUD$42.2M, 510,977 decayed teeth averted and 98.1 DALYs averted. The lifetime scenario resulted in societal cost savings of AUD$176.6M, healthcare cost-savings of AUD$122.5M, 1,309,211 decayed teeth averted and 254.9 DALYs averted. Modeling indicated 71.5% and 74.5% cost-effectiveness for the 10-year and lifetime scenarios, respectively. A three-fold health benefit for the least advantaged was found compared to the most advantaged. A 20% SSB tax in Australia is cost-effective and promotes health equity.

Is value-based healthcare a strategy to achieve universal health coverage that includes oral health? An Australian case study.

The 2021 Resolution on Oral Health by the 74th World Health Assembly supports an important health policy direction: inclusion of oral health in universal health coverage. Many healthcare systems worldwide have not yet addressed oral diseases effectively. The adoption of value-based healthcare (VBHC) reorients health services towards outcomes. Evidence indicates that VBHC initiatives are improving health outcomes, client experiences of healthcare, and reducing costs to healthcare systems. No comprehensive VBHC approach has been applied to the oral health context. Dental Health Services Victoria (DHSV), an Australian state government entity, commenced a VBHC agenda in 2016 and is continuing its efforts in oral healthcare reform. This paper explores a VBHC case study showing promise for achieving universal health coverage that includes oral health. DHSV applied the VBHC due to its flexibility in scope, consideration of a health workforce with a mix of skills, and alternative funding models other than fee-for-service.

Primary caregivers' perceptions of factors influencing preschool children's oral health: social practices perspective-a protocol for qualitative metasynthesis.

INTRODUCTION: The role of primary caregivers in setting the foundation for a child's oral health throughout life is well recognised. Due to the dominant behaviour-based approach, research to date has mainly focused on exploring individual primary caregivers' oral health knowledge and behaviours. A social science approach involving social practice theories moves beyond individual attitudes, behaviour and choices to offer a better understanding of the ways in which collective activity relates to health. This qualitative metasynthesis will involve an interpretive synthesis of data found in published qualitative literature from developed countries. The aim of the metasynthesis is to identify social practices in families from published qualitative research with caregivers on preschool children's oral health. METHODS AND ANALYSIS: This is a protocol for qualitative metasynthesis. The following databases will be used: MEDLINE, EMBASE, Global Health and Dentistry & Oral Sciences Source (DOSS) using the web-based database search platform Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus. The research team has determined search strategies by using relevant key terms. Qualitative studies published in English language on family factors related to preschool children (aged 0-5 years) from developed countries (2022 United Nations classification) will be included. Qualitative data analysis will involve thematic analysis of the reported factors influencing oral health of preschool children, from the perspective of social practice theory. Researchers will use NVivo software for organising and managing the data. ETHICS AND DISSEMINATION: No ethics approval is required, as this study does not involve human subjects. Findings will be disseminated through professional networks, conference presentations and submission to a peer-reviewed journal.

Patterns and predictors of public dental service utilisation among refugees in Victoria, Australia: a latent profile and multilevel analysis.

BACKGROUND: The purpose of the study was to explore, analyse, and describe the patterns of public dental service utilisation among the refugee populations in Victoria, Australia, and determine their predictors at the individual and contextual levels. METHODS: Data on the refugees who attended Victorian public dental services between July 2016 to June 2020 was gathered from the Dental Health Program dataset. Latent profile analysis was used to identify discrete groups among the refugee clientele with similar mean utilisation patterns across six indicator variables describing the attributes of dental services received and the site of care provision, over the study period. Multilevel multinomial logistic regression analysis was performed to examine the individual and contextual level correlates of the identified utilisation patterns. RESULTS: Six distinct profiles of public dental service utilisation were identified among the study population (n = 25,542). The largest group comprised refugees predominantly using restorative services under general course of care (38.10%), followed by extraction services under emergency course of care (23.50%). Only a small proportion were estimated as having a higher mean utilisation of preventive services under general course of care (9.10%). Multilevel analysis revealed that the following variables had a significant association with refugee utilisation pattern: at the individual-level - demographic and ethnic attributes including age, gender, region of birth, preferred language for communication, use of language interpreter services, and type of eligibility card; at the contextual-level - characteristics of refugees' neighbourhood of residence including urbanicity, socioeconomic disadvantage, delivery of Refugee Health Program at the community health centres, and spatial accessibility to public dental services via driving and public transit modes of travel. CONCLUSIONS: The study represents a significant step towards the development of an evidence-based knowledge around public dental service utilisation among Victorian refugees. Overall, the study findings reiterate the critical need for targeted strategies to promote the importance of routine dental visits, oral disease prevention, and timely intervention among refugee groups.

Hospitalizations from Birth to 28 Years in a Population Cohort of Individuals Born with Five Rare Craniofacial Anomalies in Western Australia.

OBJECTIVE: To describe trends, age-specific patterns, and factors influencing hospitalizations for 5 rare craniofacial anomalies (CFAs). METHODS: Data on livebirths (1983-2010; n = 721 019) including rare CFA (craniofacial microsomia, mandibulofacial dysostosis, Pierre Robin sequence, Van der Woude syndrome, and frontonasal dysplasia), episodes of death, and demographic and perinatal factors were identified from the Western Australian Register of Developmental Anomalies, Death Registrations and Midwives Notification System. Information on incident craniofacial and noncraniofacial related admissions, length of hospital stay, and intensive care and emergency-related admissions were identified using principal diagnosis and procedural codes were extracted from the Hospital Morbidity Data Collection and linked to other data sources. Associations of hospitalizations by age groups as well as demographic and perinatal factors were expressed as incidence rate ratio (IRR). RESULTS: The incident hospitalizations were 3 times as high for rare CFA (IRR 3.22-3.72) throughout childhood into adolescence than those without. Children with rare CFA had 3-4 times as many potentially preventable hospitalizations until 18 years of age than those without. Specifically, respiratory infections (IRR 2.13-2.35), ear infections (IRR 7.92-26.28), and oral health-related conditions contributed for most noncraniofacial admissions until the adolescence period. A greater incidence of noncraniofacial related hospitalizations was observed among Indigenous children, births with intrauterine growth restrictions, and families with high socioeconomic disadvantage. CONCLUSIONS: Throughout childhood, individuals with rare CFA had greater hospital service use, specifically for potentially preventable conditions, than those without. These population-level findings can inform new preventive strategies and early disease management targeted toward reducing preventable hospitalizations.

Patterns, trends, and factors influencing hospitalizations for craniosynostosis in Western Australia. A population-based study.

Understanding hospital service use among children with a diagnosis of craniosynostosis (CS) is important to improve services and outcomes. This study aimed to describe population-level trends, patterns, and factors influencing hospitalizations for craniosynostosis in Western Australia. Data on live births (1990-2010; n = 554,624) including craniosynostosis, episodes of death, demographic, and perinatal factors were identified from the midwives, birth defects, hospitalizations, and death datasets. Information on craniosynostosis and non-craniosynostosis-related admissions, cumulative length of hospital stay (cLoS), intensive care unit, and emergency department-related admissions were extracted from the hospitalization dataset and linked to other data sources. These associations were examined using negative binomial regression presented as annual percent change and associations of hospitalizations by age groups, demographic, and perinatal factors were expressed as incidence rate ratio (IRR). We found an increasing trend in incident hospitalizations but a marginal decline in cLoS for craniosynostosis over the observed study period. Perinatal conditions, feeding difficulties, nervous system anomalies, respiratory, and other infections contributed to majority of infant non-CS-related admissions.Respiratory infections accounted for about twice the number of admissions for individuals with CS (IRRs 1.94-2.34) across all observed age groups. Higher incidence of non-CS hospitalizations was observed among females, with associated anomalies, to families with highest socioeconomic disadvantage and living in remote areas of the state.   Conclusion: Marginal reduction in the cLoS for CS-related admissions observed over the 21-year period are potentially indicative of improved peri-operative care. However, higher incidence of respiratory infection-related admissions for syndromic synostosis is concerning and requires investigation.

Factors associated with access to dental care among refugees: A systematic review of quantitative studies.

OBJECTIVES: To identify, appraise and synthesize the published evidence from quantitative studies on the individual and contextual-level factors determining access to dental care among refugees worldwide. METHODS: A systematic literature search was conducted until the last week of February 2022 in four electronic databases - MEDLINE, Embase, Web of Science (all databases) and APA PsycINFO - without any restrictions. Quantitative studies published in English language and meeting the a priori eligibility criteria were reviewed and data extracted. Quality assessment was conducted using the National Institutes of Health tool. The identified factors were stratified according to the framework of the Behavioural Model of Health Services Use, and the evidence related to each of these factors was summarized in tables. Narrative synthesis of the findings was conducted. RESULTS: The search retrieved 6776 unique records, of which 69 were deemed eligible for full-text screening and nine studies were included in the final data analysis and synthesis. The studies were rated to be of 'fair' quality at best. Self-reported previous dental visits was the most commonly used measure of access. Associations between individual-level factors and dental care access were most frequently examined (predisposing [n = 6], need [n = 2] and enabling [n = 1]), while the contextual-level factors were rarely examined (predisposing and enabling [n = 1, each]). CONCLUSIONS: Individual-level predisposing factors, such as English language proficiency, education, health and dental literacy and acculturation and integration, were shown to be significantly associated with refugees' access. There is limited evidence to determine the effect of individual enabling and need and contextual factors.

Epidemiology of Hospital Admissions for Craniosynostosis in Australia: A Population-Based Study.

To describe trends, age, and sex-specific patterns of population hospital admissions with a diagnosis of craniosynostosis (CS) in Australia.Population data for hospital separations (in-patient) from public and private hospitals (July 1996-June 2018) were obtained from the publicly available Australian Institute of Health and Welfare (AIHW) National Hospital Morbidity Database.The outcome variables were hospital separation rates (HSR) (number of hospital separations divided by the estimated resident population [ERP] per year) and average length of stay (aLOS) (patient days divided by the number of hospital separations) with a diagnosis of CS. Trends in HSR and aLOS adjusted for age, sex, and type of CS were investigated by negative binomial regression presented as annual percent change (APC).In 8057 admissions identified, we observed no significant change in the annual trend for HSR for the 22-year period. However, a marginal annual decrease of 1.6% (95% CI: -0.7, -2.4) in the aLOS was identified for the same time period. HSR were higher for males, infants, and single suture synostosis. aLOS was 3.8 days (95% CI: 3.8, 3.9) per visit, longer for syndromic conditions.There was a minor reduction in the average length of hospital stay for CS over the 22-year period potentially indicative of improved care. Population-level information on hospitalisations for rare craniofacial conditions can inform research, clinical, and surgical practice.

Economic Evaluations of Preventive Interventions for Dental Caries and Periodontitis: A Systematic Review.

OBJECTIVES: To critically examine the methods used for full economic evaluations of preventive interventions for dental caries and periodontitis. METHODS: Published literature post-2000 was searched to April 2021. Based on a developed intervention classification framework for dental caries and periodontitis, only universal, selective or indicated interventions were included in this review. The Drummond 10-point checklist was used for quality appraisal. RESULTS: Of 3,007 unique records screened for relevance, 73 studies were reviewed. Most model-based studies (61/73) used cost-effectiveness analysis (49%) or cost-benefit analysis (28%). Trial-based studies (16/73) commonly used cost-effectiveness analysis (59%). Four studies used both economic evaluation methods. Sixty-four papers (88%) were on dental caries, eight papers (11%) focused on periodontitis, and one paper (1%) included both oral diseases; 72% of model-based and 82% of trial-based studies were of good quality. The most frequently investigated dental caries preventive interventions were water fluoridation (universal intervention; cost-saving or cost-effective), fissure sealant and fluoride varnish (selective and indicated interventions; cost-effectiveness outcomes were inconsistent). Supportive periodontal therapy with oral health education (indicated intervention; cost-effective) was the most frequently evaluated preventive intervention for periodontitis. Thirty percent of studies with a time horizon > 1 year did not apply an appropriate discount rate and 26% did not comprehensively discuss other important considerations beyond the technical analysis. CONCLUSIONS: Generic health outcome measures should be incorporated for economic evaluations on preventive interventions for dental caries and periodontitis, and an increased focus to prevent periodontitis using economic evaluation methods is needed to inform resource allocation and policy decision-making.

Disparities in spatial accessibility to public dental services relative to estimated need for oral health care among refugee populations in Victoria.

OBJECTIVES: To examine the spatial accessibility to public dental services (PDS) relative to the estimated oral health needs of refugee populations within the state of Victoria, Australia. METHODS: The study employed enhanced two-step floating catchment area method to measure spatial accessibility to PDS by driving and public transit modes at statistical area level 2 (SA2). Principal component analysis of select census-derived socioeconomic variables specific to the refugee population was conducted to derive an area-based indicator of refugee oral health needs, also at SA2 level. Individual indices were then developed for each of these components using standardized z-scores. Finally, an integrated need-accessibility index was developed to identify low-accessibility areas associated with high needs. RESULTS: The results show clear contrast in spatial accessibility to PDS for the refugee populations between metropolitan and rural areas as well as between driving and public transit modes. There are critical limitations in accessibility for refugees living in the rural areas and those dependent on public transit mode for travel. Also, there is evident disparity between the estimated oral health needs of refugees in metropolitan and rural areas. Overall, approximately 29% of all SA2s with refugee population are in the 'High' needs category, which comprise 19.8% of the total Victorian refugee population. Integrating accessibility and oral health needs measures revealed that about 30% and 18% of refugee population are identified as under-serviced, when considering driving and public transit modes respectively. CONCLUSION: The findings provide implications for researchers and policy makers to address the inequalities in access to PDS among the refugee population in Victoria. The methodology outlined in this study provides a complementary approach in planning oral health service provision in the absence of population level data at a small-area scale on access to dental services or need for oral health care.

Undergraduate dental students' perception of paediatric dental teaching in an urban and rural Australian dental school.

BACKGROUND: Confidence in performing paediatric dental treatment is important as it ensures better oral health outcomes in the patient's adulthood. AIM: To investigate the confidence and attitudes of final year dentistry students, attending an urban and rural dental programme, towards their paediatric dentistry training. DESIGN: A questionnaire was distributed to final year dentistry students at the urban-based university, The University of Queensland, and at the rural-based university, La Trobe University. The questionnaire collected information using 5-point Likert scale and short-answer questions, which explored the theoretical, observational, preclinical and clinical aspects of students' paediatric dentistry training. Jamovi and GraphPad Prism were used for data analysis and the creation of graphs. RESULTS: The questionnaire was completed by 32 rural students and 47 urban students, with a response rate of 79%. Rural students were found to be less confident with the theory on restorative procedures than urban students. Observations of a dentist performing treatment on child were completed by a significantly larger proportion of urban students (70.2%) than rural students (46.9%). Students from both universities reported to have developed the least confidence in the preclinical training of pulp therapies and expressed the need for additional preclinical sessions for more training. At both universities, students indicated they were the least confident in the clinical practice of pulp therapies and management of traumatic dental injuries. Urban students were found to be more confident than their rural counterparts in the clinical practice of examination, treatment planning and preventative procedures, as well as in restorative procedures. CONCLUSIONS: Both urban and rural students were found to have the least confidence in preclinical and clinical skills related to pulp therapies. Restorative dentistry was an area in which urban students were significantly more confident than rural students in both the theoretical and the clinical aspects.

How does the dental benefits act encourage Australian families to seek and utilise oral health services?

BACKGROUND: This study aimed to analyse the content of the Dental Benefits Act 2008 as a foundation for the Child Dental Benefits Schedule (CDBS) to determine how the Act encourages Australian families to seek and utilise oral health services. METHODS: This was a qualitative narrative document analysis conducted in 2022. Data was collected by searching formal websites for retrieving documents that reported the Australian Dental Benefits Act. The eligibility of the retrieved documents was assessed based on authenticity, credibility, representativeness, and meaningfulness of the data. A seven-steps procedure was applied for framework analysis. RESULTS: The content of the Dental Benefits Act 2008 provides directions on the three categories of operational, collective, and constitutional rules. Operational rules at the level of oral health providers and the population, as the service end users, can be demonstrated as rules in use in a mutual interaction with the collective and constitutional rules. The consequence of governing the rules at the community level can easily define how the oral health services are provided and utilised. The response is sent to the government level for better regulation of oral health service delivery and utilisation. Then, with interaction and advocacy with the diverse range of stakeholders and interdisciplinary partnerships, with community groups, non-government sectors and councils, the rules can be transformed, adopted, monitored, and enforced. Another mechanism of response has occurred at the providers' and users' level and to the operational rules to community groups and stakeholders via advertising and promoting the utilisation and provision of oral health services. CONCLUSION: This study integrates the perspective of politicians with those of policy makers to reconsider the role and significance of the rules based on the triple collaborations among oral health users and oral service providers, the community, and the stakeholders as well as the government. A comprehensive attention is still needed in future revisions of the Dental Benefits Act 2008 according to the contextual factors, socioeconomic and geographical attributes of the population for better implementation of de facto rules and more effective outcomes of the interventions. It is recommended that further research be undertaken utilising a mix-method approach for a holistic view prior to further revisions of the Act or proposal of probable upcoming schemes.

Education/Training Interventions to Improve Oral Health of Adults with Intellectual Disability.

People with intellectual disability have poorer oral health outcomes and experience greater difficulties accessing dental services than the rest of the community. Interdisciplinary educational programs for those involved in oral health decision making for people with intellectual disability aim to improve their oral health. This scoping review explored education/training interventions related to the oral health of adults with intellectual disability. Interventions targeted dental health and non-dental health professionals, adults with intellectual disability, and their paid and unpaid supporters. Six electronic databases were searched using PRISMA guidelines and the Crowes critical appraisal tool. The search strategy, plus the application of the inclusion and exclusion criteria, presented in the body of the manuscript, led to the selection of 20 papers for inclusion into this review. The quality of undergraduate tuition relating to disability was reported to be poor, but students and dental health professionals expressed interest in expanding their knowledge in this area. Disability-support workers and primary carers of people with intellectual disability reported improved knowledge and attitude, but the oral health status of the people they supported was not impacted. No research was found that explored the perspectives of non-dental health professionals. Oral health training/education contributes to systemic barriers in general health, wellbeing, and social inclusion of people with intellectual disability. Revision of disability-related programs in general dentistry courses and longitudinal impact research is needed.

Developing and pilot testing an oral health screening tool for diabetes care providers.

BACKGROUND: People with poorly managed diabetes are at greater risk of periodontal disease. Periodontal disease that is not effectively managed can affect glycaemic levels. Diabetes care providers, including general practitioners and diabetes educators, are encouraged to promote oral health of their clients. However, valid and reliable oral health screening tools that assess the risk of poor oral health, that are easy to administer among non-dental professionals, currently do not exist. Existing screening tools are difficult to incorporate into routine diabetes consultations due to their length. Thus, this study aimed to develop and pilot a short oral health screening tool that would identify risk of existing oral diseases and encourage appropriate referrals to the dental service. METHODS: A three-item screening tool was developed after a comprehensive review of the literature and consensus from an expert panel. The tool was then piloted as part of a larger cross-sectional survey of 260 adults with diabetes who were accessing public diabetes clinics at two locations in Sydney, Australia. As part of the survey, participants completed the three-item screening tool and a 14-item validated tool, the Oral Health Impact Profile (OHIP-14), which has been used previously in the preliminary validation of screening tools. Sensitivity and specificity analyses were then undertaken comparing the results of the two tools. RESULTS: A statistically significant correlation was found between the shorter screening tool and the OHIP-14 (rho = 0.453, p < 0.001), indicating adequate validity. The three-item tool had high sensitivity (90.5%, 95% CI 84.9%, 94.7%), with a specificity of 46.3% (95% CI 37.7%, 55.2%). The negative predictive value was 81.4% (95% CI 71.3, 89.3). No single item performed as well regarding sensitivity and negative predictive value when compared to the three items collectively. CONCLUSIONS: The three-item screening tool developed was found to be valid and sensitive in identifying risk of poor oral health, requiring oral health referrals, among people with diabetes in this pilot. This is a simple, accessible tool that diabetes care providers could incorporate into their routine consultations. Further validation against comprehensive dental assessments is needed to reassess the tool's specificity and sensitivity in diverse settings.

Breastmilk influences development and composition of the oral microbiome.

Background: Human microbiomes assemble in an ordered, reproducible manner yet there is limited information about early colonisation and development of bacterial communities that constitute the oral microbiome. Aim: The aim of this study was to determine the effect of exposure to breastmilk on assembly of the infant oral microbiome during the first 20 months of life. Methods: The oral microbiomes of 39 infants, 13 who were never breastfed and 26 who were breastfed for more than 10 months, from the longitudinal VicGeneration birth cohort study, were determined at four ages. In total, 519 bacterial taxa were identified and quantified in saliva by sequencing the V4 region of the bacterial 16S rRNA genes. Results: There were significant differences in the development of the oral microbiomes of never breastfed and breastfed infants. Bacterial diversity was significantly higher in never breastfed infants at 2 months, due largely to an increased abundance of Veillonella and species from the Bacteroidetes phylum compared with breastfed infants. Conclusion: These differences likely reflect breastmilk playing a prebiotic role in selection of early-colonising, health-associated oral bacteria, such as the Streptococcus mitis group. The microbiomes of both groups became more heterogenous following the introduction of solid foods.

Diabetes and Oral Health (DiabOH): The Perspectives of Primary Healthcare Providers in the Management of Diabetes and Periodontitis in China and Comparison with Those in Australia.

Diabetes and periodontal disease are highly prevalent conditions around the world with a bilateral causative relationship. Research suggests that interprofessional collaboration can improve care delivery and treatment outcomes. However, there continues to be little interprofessional management of these diseases. DiabOH research aims to develop an interprofessional diabetes and oral health care model for primary health care that would be globally applicable. Community medical practitioners (CMPs), community health nurses (CNs), and dentists in Shanghai were recruited to participate in online quantitative surveys. Response data of 76 CMPs, CNs, and dentists was analysed for descriptive statistics and compared with Australian data. Health professionals in China reported that, while screening for diabetes and periodontitis, increasing patient referral and improving interprofessional collaboration would be feasible, these were not within their scope of practice. Oral health screening was rarely conducted by CMPs or CNs, while dentists were not comfortable discussing diabetes with patients. Most participants believed that better collaboration would benefit patients. Chinese professionals concurred that interprofessional collaboration is vital for the improved management of diabetes and periodontitis. These views were similar in Melbourne, except that Shanghai health professionals held increased confidence in managing patients with diabetes and were more welcoming to increased oral health training.

Mentoring of oral health professionals is crucial to improving access to care for people with special needs.

INTRODUCTION: Individuals with special health care needs continue to experience difficulties with accessing regular dental care. This has largely been due to clinicians feeling they lack the training and experience to manage their needs. The aim of this study was to determine whether working closely with specialists in special need dentistry influenced the willingness of clinicians to treat patients with special needs. MATERIALS AND METHODS: Semi-structured interviews were conducted with specialists and clinicians involved in these mentoring initiatives. Qualitative thematic analysis was used to determine perspectives towards how this additional support influenced their willingness to treat individuals with special needs. RESULTS: The views of all participants towards these supports were positive with clinicians feeling it not only offered them opportunities to learn from the specialists, but also increased their willingness to treat individuals with special needs and the timeliness and quality of care they were able to provide. Likewise, despite some concerns about the inappropriate use of specialist support, the specialists felt these mentoring relationships offered many benefits including improving timely access to care and ensuring individuals were able to receive appropriate care. CONCLUSIONS: Mentoring provided by specialists in special needs dentistry improved the willingness of clinicians to provide care for individuals with special health care needs. Supports such as these are likely to be crucial to overcoming concerns of clinicians about their ability to manage the needs of these individuals and begin to address a significant barrier to access of care for individuals with special health care needs.

An overview of methodological approaches in systematic reviews.

AIM: The aim of this overview is to identify and collate evidence from existing published systematic review (SR) articles evaluating various methodological approaches used at each stage of an SR. METHODS: The search was conducted in five electronic databases from inception to November 2020 and updated in February 2022: MEDLINE, Embase, Web of Science Core Collection, Cochrane Database of Systematic Reviews, and APA PsycINFO. Title and abstract screening were performed in two stages by one reviewer, supported by a second reviewer. Full-text screening, data extraction, and quality appraisal were performed by two reviewers independently. The quality of the included SRs was assessed using the AMSTAR 2 checklist. RESULTS: The search retrieved 41,556 unique citations, of which 9 SRs were deemed eligible for inclusion in final synthesis. Included SRs evaluated 24 unique methodological approaches used for defining the review scope and eligibility, literature search, screening, data extraction, and quality appraisal in the SR process. Limited evidence supports the following (a) searching multiple resources (electronic databases, handsearching, and reference lists) to identify relevant literature; (b) excluding non-English, gray, and unpublished literature, and (c) use of text-mining approaches during title and abstract screening. CONCLUSION: The overview identified limited SR-level evidence on various methodological approaches currently employed during five of the seven fundamental steps in the SR process, as well as some methodological modifications currently used in expedited SRs. Overall, findings of this overview highlight the dearth of published SRs focused on SR methodologies and this warrants future work in this area.
