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.

'It's like being in a tunnel': Understanding the patient journey from tooth loss to life with removable dentures.

INTRODUCTION: The aim of this study was to conceptualise the key stages of the patient journey in the provision of a new denture and examine the factors leading to successful patient-related outcomes. METHODS: Two partially dentate patient samples were included: (i) Denture wearers - patients who had a denture fitted within the previous five years and (ii) New dentures - patients receiving treatment for a new or replacement denture. The methods involved direct targeted participant observations of the denture fitting process, debriefing interviews and a follow-up focus group exploring the patient journey. Data were analysed through the use of phenomenology and grounded theory. RESULTS: Interviews were completed with twenty participants of the denture-wearing sample (11 males and nine females, age range 22 to 86 years). Thirteen participants were included in the treatment journey sample in two primary care settings (six males and seven females, age range 55 to 101 years). Tooth loss and recovery was described as being in an 'emotional tunnel' resulting from 'bodyphonic processes' associated with tooth loss. 'Bodyphonia' subsequently became the context for 'taking control' and 'managing disclosure' when living with a removable denture. Different courses through this process can be readily observed, moderated by different variables (i.e., previous experience, working knowledge, a good fit, the treatment alliance, negotiated compromises and bounded responsibility). CONCLUSIONS: An'integrating framework' that seeks to describe the patient journey from the experience of tooth loss to recovery with a denture is proposed. This framework could be used to aid development of a clinical pathway to guide treatment options. CLINICAL SIGNIFICANCE: This paper conceptualises the patient journey. It stresses the importance of understanding the stages patients go through and highlights that for the dental team, the try-in stage is perhaps the best stage to give information about the denture and plans for continued care.

Ethnographic perspectives of mothers and professionals on including children with disabilities in oral health in the Kingdom of Saudi Arabia.

BACKGROUND: Children with disabilities generally face poorer oral health outcomes compared with their non-disabled peers due to a range of factors including inadequate oral hygiene, infrequent dental visits and systemic barriers in accessing care. AIM: This ethnographic study explored the perspectives of caregivers and professionals to identify the ways that children with disabilities are included in oral health. DESIGN: A purposive sample of 10 caregivers, all mothers with disabled children aged 9-15 years, five healthcare providers and five educators in Saudi Arabia, participated. Data collection used participant observation and semi-structured in-depth interviews. Data were analysed using reflexive thematic analysis. RESULTS: The findings suggest that mothers lacked a supportive environment to develop their skills and knowledge about oral health care, preventing them from including their children in oral health. Inaccessible services added to the exclusion of both mothers and children. Some dental professionals exhibited poor communication skills and discriminatory attitudes towards the children and problematising mothers. Educators tended to discuss disabled children in terms of inability, displaying a deficit approach to impairment. CONCLUSIONS: The evidence suggests the exclusion of mothers from oral health. This has an impact on how they enable their children. Recommendations include adopting a social model of disability in dental education and policies in Saudi Arabia to address inequalities. Provision of support, education and focusing on societal barriers moves towards inclusion rather than conceptualising disability as an individual problem.

Dental caries and school readiness in 5-year-olds: A birth cohort data linkage study.

OBJECTIVE: To describe the association between dental caries and school readiness in 5-year-old children taking part in the Born in Bradford (BiB) birth cohort, UK. METHODS: The Early Years Foundation Stage Profile (EYFSP) assesses the school readiness of young children and is strongly predictive of future academic attainment. Children are recorded as 'emerging' (below expected), 'expected', or 'exceeding' in five key learning areas. The Oral Health Survey of 5-year-olds (OHS5) is undertaken biennially in England, assessing caries experience at a dentine threshold (d3mft). EYFSP and OHS5 were available for a proportion of children participating in BiB. Odds ratios and confidence intervals for caries experience were established, and odds ratios adjusted for significant sociodemographic variables. RESULTS: EYFSP and OHS5 data were available for 2.5% (n = 346) BiB participants. Nearly half (45.2%) had caries. A measure of socio-economic status, receiving free school meals, was the only demographic variable strongly related to caries experience (OR: 2.8, 95% CI: 1.6-4.9). After adjustment, children 'emerging' in EYFSP learning areas had 1.6- to 2.2-fold (95% CI: 1.0-3.8) higher odds of experiencing caries. Children 'exceeding' EYFSP learning areas had 2.3- to 4-fold (95% CI: 0.1-0.9) lower odds of caries experience. CONCLUSION: This is the first study to explore the association between caries experience and school readiness using a holistic assessment tool. The association was found across different learning areas and was comparable to and independent of socio-economic status. The findings indicate oral health-related absenteeism is not a causative factor. EYFSP shows potential to enhance the targeting of preventive interventions at a child, class or school level.

Setting the context for a complex dental intervention of role substitution in care homes: Initial process evaluation findings.

OBJECTIVES: SENIOR (uSing rolE-substitutioN In care homes to improve oRal health) is a randomised controlled trial designed to determine whether role substitution could improve oral health for this population. A parallel process evaluation was undertaken to understand context. This paper reports on the first phase of the process evaluation. BACKGROUND: The oral health and quality-of-life of older adults residing in care homes is poorer than those in the community. Oral health care provision is often unavailable and a concern and challenge for managers. The use of Dental Therapists and Dental Nurses rather than dentists could potentially meet these needs. MATERIALS AND METHODS: Semi-structured interviews were conducted with 21 key stakeholders who either worked or had experience of dependent care settings. Questions were theoretically informed by the: Promoting Action on Research Implementation in Health Services (PAHRIS) framework. The focus was on contextual factors that could influence adoption in practice and the pathway-to-impact. Interviews were fully transcribed and analysed thematically. RESULTS: Three themes (receptive context, culture, and leadership) and 11 codes were generated. Data show the complexity of the setting and contextual factors that may work as barriers and facilitators to intervention delivery. Managers are aware of the issues regarding oral health and seek to provide best care, but face many challenges including staff turnover, time pressures, competing needs, access to services, and financial constraints. Dental professionals recognise the need for improvement and view role substitution as a viable alternative to current practice. CONCLUSION: Although role substitution could potentially meet the needs of this population, an in-depth understanding of contextual factors appeared important in understanding intervention delivery and implementation.

Using Standardised International Oral Health-Related Datasets in 6 Countries.

INTRODUCTION: Oral diseases affect a significant proportion of the world's population, yet international comparisons involving oral health outcomes have often been limited due to differences in the way country-level primary data are collected. In response to this, the World Dental Federation (FDI) Oral Health Observatory project was launched with the goal of collecting and producing standardised international data on oral health across countries. The aim of this descriptive cross-sectional study was to examine associations between self-reported general health and a range of factors (sociodemographics, oral health-related behaviours, oral impacts, clinical variables) using these standardised international datasets. METHODS: Dentists within FDI member National Dental Associations who chose to take part in the project were selected using a multistage sampling method. The number of dentists in each cluster was set according to the proportion of the national population living in the area, and 50 patients per dentist were systematically approached to take part. Patients and dentists completed 2 separate questionnaires on a mobile app. Ordinal logistic regression (conducted in December 2022) was used to analyse the linked patient and dentist data from 6 countries: China (n = 2242); Colombia (n = 1029); India (n = 999); Italy (n = 711); Japan (n = 1271); and Lebanon (n = 798). Self-reported general health was the dependent variable, with age, sex, education, self-reported oral health-related behaviours, self-reported oral impacts, and clinical variables acting as the independent variables. RESULTS: The results demonstrated a different pattern of associations in the different countries. Better self-reported general health was associated with degree-level education in all 6 countries and with reporting no oral impact and no sensitive teeth in 4 countries. Several country-specific patterns were also found, including the importance of tooth brushing in Colombia, periodontal health in Italy, and differing associations with sugary drinks consumption in India and Japan. CONCLUSIONS: These descriptive findings provide a basis for further research and, importantly, for advocacy in identifying patient oral health care needs according to both person-reported and clinical aspects. This can facilitate optimisation of service provision and potentially influence policy and investments.

Using a theoretically informed process evaluation alongside a trial to improve oral health for care home residents.

BACKGROUND: Poor oral health is common among older adults residing in care homes impacting their diet, quality of life, self-esteem, general health and well-being. The care home setting is complex and many factors may affect the successful implementation of oral care interventions. Exploring these factors and their embedded context is key to understanding how and why interventions may or may not be successfully implemented within their intended setting. OBJECTIVES: This methodology paper describes the approach to a theoretically informed process evaluation alongside a pragmatic randomised controlled trial, so as to understand contextual factors, how the intervention was implemented and important elements that may influence the pathways to impact. MATERIALS AND METHODS: SENIOR is a pragmatic randomised controlled trial designed to improve the oral health of care home residents in the United Kingdom. The trial uses a complex intervention to promote and provide oral care for residents, including education and training for staff. RESULTS: An embedded, theoretically informed process evaluation, drawing on the PAHRIS framework and utilising a qualitative approach, will help to understand the important contextual factors within the care home that influence both the trial processes and the implementation of the intervention. CONCLUSION: Utilising an implementation framework as the basis for a theoretically informed process evaluation provides an approach that specifically focuses on the contextual factors that may influence and shape the pathways to impact a given complex intervention a priori, while also providing an understanding of how and why an intervention may be effective. This contrasts with the more common post hoc approach that only focuses on implementation after the empirical results have emerged.

The relationship of children's dental clinical status with school performance and school attendance in the Kingdom of Bahrain: A life-course approach.

OBJECTIVES: To examine the association between dental clinical status and school performance and school attendance in the Kingdom of Bahrain (KoB) using a life-course framework. METHODS: This time-ordered cross-sectional study included 466 school children in Grade 2 (aged 7-8 years) and their parents in the KoB. Data were collected through parents' self-administered questionnaires, children's face-to-face interviews and dental clinical examinations. Data on children's school performance and school attendance were gathered from parents and school records. Structural equation modelling (SEM) examined the direct and indirect pathways between variables. RESULTS: Children born in families with high socio-economic status (SES) were less likely to have dental caries and more likely to have better school performance at 7-8 years of age. Dentine caries was directly linked with poor school performance. Treated teeth directly predicted high school performance. The presence of dentine caries mediated the relationship of SES with school performance. CONCLUSIONS: Birth and current socio-economic factors were significant predictors of dental clinical conditions and school performance. Dental caries and fewer treated teeth directly predicted poor school performance.

A bibliometric analysis of Community Dentistry and Oral Epidemiology: Fifty years of publications.

OBJECTIVES: In celebration of the journal's 50th anniversary, the aim of the study was to review the whole collection of Community Dentistry and Oral Epidemiology (CDOE) publications from 1973 to 2022 and provide a complete overview of the main publication characteristics. METHODS: The study used bibliometric techniques such as performance and science mapping analysis of 3428 articles extracted from the Scopus database. The data were analysed using the 'Bibliometrix' package in R. The journal's scientific production was examined, along with the yearly citation count, the distribution of publications based on authors, the corresponding author's country and affiliation and citation count, citing source and keywords. Bibliometric network maps were constructed to determine the conceptual, intellectual and social collaborative structure over the past 50 years. The trending research topics and themes were identified. RESULTS: The total number of articles and average citations has increased over the years. D Locker, AJ Spencer, A Sheiham and WM Thomson were the most frequently published authors, and PE Petersen, GD Slade and AI Ismail published papers with the highest citations. The most published countries were the United States, United Kingdom, Brazil and Canada, frequently engaging in collaborative efforts. The most common keywords used were 'dental caries', 'oral epidemiology' and 'oral health'. The trending topics were healthcare and health disparities, social determinants of health, systematic review and health inequalities. Epidemiology, oral health and disparities were highly researched areas. CONCLUSION: This bibliometric study reviews CDOE's significant contribution to dental public health by identifying key research trends, themes, influential authors and collaborations. The findings provide insights into the need to increase publications from developing countries, improve gender diversity in authorship and broaden the scope of research themes.

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.

Oral health promotion through health-promoting schools in developing countries: A scoping review.

OBJECTIVES: To explore and assess what is known about oral health promotion through health-promoting primary schools in developing countries. METHODS: A scoping review was conducted using the Arksey & O'Malley framework. Web of Science, PubMed, Scopus and Cochrane Library were searched, followed by the reference lists of the resulting studies. The UN classification of developing countries was used to define the countries included and the search was between 1986 and 2021. Quality assessment was carried out using Joanna Briggs Institute's quality appraisal tools. RESULTS: The search resulted in 33 studies of which almost half were randomized controlled trials. The oral health promotion strategies were oral health education (n = 16) delivered by teachers, parents or peers, or multicomponent involving both toothbrushing (n = 15) and dietary components (n = 2). Most of the included studies were conducted in Asia (n = 25/33). CONCLUSIONS: Findings suggested that comprehensive, multicomponent theory-based oral health promotion showed improvements in oral health outcomes of schoolchildren, particularly if delivered using a whole-school approach. However, further research on feasibility and implementation of oral health promotion through health-promoting primary schools in developing countries should be considered.

Standardised Practice-Based Oral Health Data Collection: A Pilot Study in Different Countries.

BACKGROUND: The Oral Health Observatory (OHO), launched in 2014 by FDI World Dental Federation, aims to provide a coordinated approach to international oral health data collection. A feasibility project involving 12 countries tested the implementation of the methodology and data collection tools and assessed data quality from 6 countries. METHODS: National dental associations (NDAs) recruited dentists following a standardised sampling method. Dentists and patients completed paired questionnaires (N = 7907) about patients' demographics, dental attendance, oral health-related behaviours, oral impacts, and clinical measures using a mobile app. In addition, participating dentists (n = 93) completed an evaluation survey, and NDAs completed a survey and participated in workshops to assess implementation feasibility. RESULTS: Feasibility data are presented from the 12 participating countries. In addition, the 6 countries most advanced with data collection as of July 2020 (China, Colombia, India, Italy, Japan, and Lebanon) were included in the assessment of data quality and qualitative evaluation of implementation feasibility. All NDAs in these 6 countries reported interest in collecting standardised, international data for policy and communication activities and to understand service use and needs. Eighty-two percent of dentists (n = 76) reported a patient response rate of between 80% and 100%. More than 70% (n = 71) of dentists were either satisfied or very satisfied with the patient recruitment and data collection methods. There were variations in patient oral health and behaviours across countries, such as self-reporting twice-daily brushing which ranged from 45% in India to 83% in Colombia. CONCLUSIONS: OHO provides a feasible model for collecting international standardised data in dental practices. Reducing time implications, ensuring mobile app reliability, and allowing practitioners to access patient-reported outcomes to inform practice may enhance implementation.

Evolution and development of methodologies in social and behavioural science research in relation to oral health.

The aim of this introductory paper is to provide an overview of key methodological developments in social and behavioural research in oral health. In the first section, we provide a brief historical perspective on research in the field. In the second section, we outline key methodological issues and introduce the seven papers in the theme. Conceptual models can contextualize research findings and address the 'why' and 'how' instead of 'what' and 'how many'. Many models exist, albeit they need to be evaluated (and adapted) for use in oral health research and in specific settings. The increasing availability of big data can facilitate this with data linkage. Through data linkage, it is possible to explore and understand in a broader capacity the array of factors that influence oral health outcomes and how oral health can influences other factors. With advances in statistical approaches, it is feasible to consider casual inferences and to quantify these effects. There is a need for not only individual efforts to embrace causal inference research but also systematic and structural changes in the field to yield substantial results. The value of qualitative research in co-producing knowledge with and from human participants in addressing 'the how' and 'the why' factors is also key. There have been calls to employ more sophisticated qualitative methods together with mixed methods approaches as ways of helping to address the complex or Wicked Problems in population oral health. In the final section, we outline possible future methodological directions in social and behavioural oral health research including participatory approaches and the development of core outcome sets. Our overriding goal in the paper is to facilitate a critical debate in relation to methodological issues which can be used to improve understanding and generate knowledge in population oral health and that this, in turn, will help inform oral health policy and practices.

Methods to madness: The utility of complex systems science in a mad, mad world.

Existing methods in social [oral] epidemiology primarily utilize statistical models that assume static characteristics of individuals and environments. While useful, an over reliance on these methods in the social and behavioural sciences can unnecessarily limit perspective and progress as even the most advanced statistical methods cannot capture complex behaviour over time given that systems evolve, environments respond, and behaviours and beliefs crystalize or deteriorate based on a variety of social, environmental and access variables. The recent consensus statement on Future Directions for the Behavioral and Social Sciences in Oral Health acknowledges that dental, oral and craniofacial health emerge from the complex interplay of multiple factors at multiple levels over time and highlights the need for the incorporation of new and underutilized methodologies. Complex Systems Science offers a suite of tools and methodologies that are responsive to the generative mechanisms and processes that underlie population distributions of oral health and disease. Specifically, they assume intricate, dynamic interactions between individuals and groups, they facilitate the study and synthesis of interconnections between people (e.g. patients, healthcare providers and policy makers), how these change over time, any differences across settings, and provide an opportunity to guide future longitudinal data collection and intervention science more effectively. This paper aims to provide an introduction to foundational principles of complex systems, complex systems thinking, and methods found in complex systems science, including social network analysis, system dynamics models and agent-based models, and offers perspectives on the challenges faced and opportunities afforded in the incorporation of these methods into the population oral health sciences.

From micro to macro: Structural determinants and oral health.

The structural determinants of health include social, economic and political mechanisms which generate social stratification and the socioeconomic positions of individuals within society. Despite their importance, these 'causes of the causes' are still relatively under-studied within oral health research. Yet it is important to assess the effects of these 'upstream' determinants, given that most individuals cannot influence or change them. It is also important to move beyond focusing primarily on downstream determinants and approaches at the individual or household level. This review will offer a brief overview of what is currently known about structural determinants and upstream interventions in relation to oral health. The review starts by briefly summarizing oral health focused studies of structural determinants, including welfare regimes, governance and macroeconomic, social and public policies. Current knowledge on upstream interventions associated with oral health such as community water fluoridation, sugar sweetened beverage taxes and dental payment structures will also be covered. The article will then assess gaps in the research base, including current limitations and barriers-as well as opportunities-in analysing the effects of structural determinants and upstream interventions. The review finishes by suggesting next steps for better understanding and addressing these determinants and interventions-including considerations around theory, data and approaches from other fields such as systems science-with the hope that these can help make contributions to future policy decision making processes.

The CALM trial protocol: a randomised controlled trial of a guided self-help cognitive behavioural therapy intervention to reduce dental anxiety in children.

BACKGROUND: Globally, around 13% of children experience dental anxiety (DA). This group of patients frequently miss dental appointments, have greater reliance on treatment under general anaesthesia (GA) and have poorer oral health-related quality of life (OHRQoL) than their non-dentally anxious peers. Recently, a low-intensity cognitive behavioural therapy (CBT)-based, self-help approach has been recommended for management of childhood anxiety disorders. A feasibility study conducted in secondary care found this guided self-help CBT resource reduced DA and a randomised controlled trial was recommended. The present study aims to establish the clinical and cost-effectiveness of a guided self-help CBT intervention to reduce DA in children attending primary dental care sites compared to usual care. METHODS: This 4-year randomised controlled trial will involve 600 children (aged 9-16 years) and their parent/carers in 30 UK primary dental care sites. At least two dental professionals will participate in each site. They will be assigned, using random allocation, to receive the CBT training and deliver the intervention or to deliver usual care. Children with DA attending these sites, in need of treatment, will be randomly allocated to be treated either by the intervention (CBT) or control (usual care) dental professional. Children will complete questionnaires relating to DA, OHRQoL and HRQoL before treatment, immediately after treatment completion and 12 months post-randomisation. Attendance, need for sedation/GA and costs of the two different approaches will be compared. The primary outcome, DA, will be measured using the Modified Child Dental Anxiety Scale. Scores will be compared between groups using a linear mixed model. DISCUSSION: Treating dentally anxious patients can be challenging and costly. Consequently, these children are frequently referred to specialist services for pharmacological interventions. Longer waiting times and greater travel distances may then compound existing healthcare inequalities. This research will investigate whether the intervention has the potential to reduce DA and improve oral health outcomes in children over their life-course, as well as upskilling primary dental healthcare professionals to better manage this patient group. TRIAL REGISTRATION: This clinical trial has been registered with an international registry and has been allocated an International Standard Randomised Controlled Trial Number (ISRCTN27579420).

Gender inequities in dental research publications: Findings from 20 years.

BACKGROUND: The first steps towards gender equity in science are measuring the magnitude of inequity and increasing awareness of the problem. OBJECTIVES: To describe trends in gender disparities in first and last authorship in the most cited dental publications and general dental literature over a 20-year period. METHODS: Articles and bibliometric data were retrieved from the Scopus database for the period 1996 to 2015. Two groups of 1000 articles each were retrieved: a random sample and another sample of top-cited articles for each year. The gender of the first and last author of each publication was manually identified. When this was not possible, we used an online software platform (https://genderize.io/). Descriptive analyses identified the proportion of women first and last authors in both samples, stratifying by dental discipline and geographic region. Trends were ascertained by frequency metrics across years. Gender disparity was observed in both first and last authorship, with a larger gap being observed in the top-cited sample. RESULTS: Women led 28.4% and 20.3% of articles in the random and top-cited samples, respectively. A similar pattern was observed for the last authorship group (22.1% and 16.1%, respectively). An increasing trend in the proportion of articles led by women over time was observed in both samples. This increase was larger in the top-cited sample (from 15.0% in 1996-2000 to 25.1% in 2015) than in the random sample (from 26.3% in 1996-2000 to 33.2% in 2011). CONCLUSIONS: Clear gender disparities in dental research publications in the last 20 years were identified in both general and top-cited manuscripts, across dental disciplines, across countries, across first and last authorship, and over time. It is paramount that actions are taken to attract, retain and promote women in science, as well as to monitor and ensure progress towards gender equity.

An international Delphi survey and consensus meeting to define the core outcome set for trigeminal neuralgia clinical trials.

BACKGROUND: Trigeminal neuralgia (TN) is an excruciating unilateral facial pain, which negatively affects patient's quality of life. Historically, it has been difficult to compare treatment efficacy due to the lack of standardized outcomes. In addition, patients' perspective has seldomly been acknowledged. The aim of this study was to reach consensus on what outcomes of treatment are important to different TN stakeholders (patients, clinicians and researchers), to identify the TN Core Outcome Set (TRINCOS). METHODS: A list of outcomes identified through a systematic review and focus group work was used to develop the survey questionnaire. A three-round Delphi was conducted. Participants were asked to score the outcomes on scale from 1 to 9 (1-3 not important;4-6 important but not critical;7-9 critical). Outcomes scored as critical by ≥70% and not important by <15% were retained, and those for which no consensus was reached were discussed at a consensus meeting. RESULTS: Of the 70 participants who completed the Delphi, 26 were patients, 38 were clinicians and six were researchers. Of the 40 outcomes presented, 17 were scored as critical and no consensus was met for 23 outcomes. Agreement was reached during a consensus meeting on 10 outcomes across six domains (pain, side effects, social impact, quality of life, global improvement, and satisfaction with treatment). CONCLUSION: Implementation of TRINCOS in future clinical trials will improve homogeneity of studies' results, reduce the redundancy in the outcome assessment and effectively allow comparison of different treatments to better inform researchers, clinicians and most importantly patients, about the efficacy of the different treatments. SIGNIFICANCE: Implementation of a 10-item core outcome set in trigeminal neuralgia will improve comparability between studies allowing patients to have faster access to better treatments.

"They Could Have Cut My Head Off and I Wouldn't Have Cared"-A Qualitative Study of Patient Experiences and the Impact of Trigeminal Neuralgia.

AIMS: To understand, from the patient perspective, the meaning of living with trigeminal neuralgia (TN) and what the patient-desired outcomes of treatment are. METHODS: A qualitative study involving focus group work with 14 participants with a diagnosis of TN was conducted. The discussions were recorded and transcribed verbatim and analyzed using framework analysis. RESULTS: Four themes and 14 subthemes were identified. Theme 1 reflects the uncertainty about TN etiology and prognosis; theme 2 includes descriptions of the mental, social, and physical impacts of TN that contrast with coping mechanisms developed over time; theme 3 reflects participants' views of what a successful treatment means and the specific outcomes they expect following treatment, as well as patient willingness to self-manage their conditions while supported; and theme 4 highlights the importance of appropriate and timely access to health care and the importance of peer support. CONCLUSION: This study confirms the need to move beyond the biologic models of disease to patient-centered care and research approaches.

uSing rolE-substitutioN In care homes to improve ORal health (SENIOR): a study protocol.

BACKGROUND: Dental service provision in the care home sector is poor, with little emphasis on prevention. Emerging evidence suggests that the use of Dental Care Professionals (dental therapists and dental nurses) as an alternative to dentists has the potential to improve preventive advice, the provision of care and access to services within care homes. However, robust empirical evidence from definitive trials on how to successfully implement and sustain these interventions within care homes is currently lacking. The aim of the study is to determine whether Dental Care Professionals could reduce plaque levels of dentate older adults (65 + years) residing in care homes. METHODS: This protocol describes a two-arm cluster-randomised controlled trial that will be undertaken in care homes across Wales, Northern Ireland and England. In the intervention arm, the dental therapists will visit the care homes every 6 months to assess and then treat eligible residents, where necessary. All treatment will be conducted within their Scope of Practice. Dental nurses will visit the care homes every month for the first 3 months and then three-monthly afterwards to promulgate advice to improve the day-to-day prevention offered to residents by carers. The control arm will be 'treatment as usual'. Eligible care homes (n = 40) will be randomised based on a 1:1 ratio (20 intervention and 20 control), with an average of seven residents recruited in each home resulting in an estimated sample of 280. Assessments will be undertaken at baseline, 6 months and 12 months and will include a dental examination and quality of life questionnaires. Care home staff will collect weekly information on the residents' oral health (e.g. episodes of pain and unscheduled care). The primary outcome will be a binary classification of the mean reduction in Silness-Löe Plaque Index at 6 months. A parallel process evaluation will be undertaken to explore the intervention's acceptability and how it could be embedded in standard practice (described in a separate paper), whilst a cost-effectiveness analysis will examine the potential long-term costs and benefits of the intervention. DISCUSSION: This trial will provide evidence on how to successfully implement and sustain a Dental Care Professional-led intervention within care homes to promote access and prevention. TRIAL REGISTRATION: ISRCTN16332897 . Registered on 3 December 2021.
