All-cause and cause-specific mortality in US adults with periodontal diseases: A prospective cohort study.

AIM: This prospective cohort study investigated the association between periodontal diseases (PDs) and all-cause and cause-specific mortality. MATERIALS AND METHODS: We utilized adult participants recruited from six National Health and Nutrition Examination Survey cycles (1999-2014) and linked mortality data from the National Death Index up to December 2019. Baseline clinical periodontal examinations were performed by trained and calibrated examiners. All-cause and cause-specific mortality was modelled through multivariable Cox proportional hazards and Fine-Gray models to account for competing risks. All models were adjusted for demographic and lifestyle variables, clinical measurements and comorbidities. RESULTS: Overall, 15,030 participants were included, with a median length of follow-up of 9 years. Risk of all-cause mortality was 22% greater in people with PD than the control group (adjusted hazard ratio [HR]: 1.22, 95% confidence interval [CI]: 1.12-1.31). Risks of mortality by cardiovascular diseases (CVD), respiratory disease and diabetes were highest in participants with severe PD (CVD-sub-distribution HR [SHR]: 1.38, 95% CI: 1.16-1.64; respiratory-SHR: 1.62, 95% CI: 1.07-2.45; diabetes-SHR: 1.68, 95% CI: 1.12-2.53). CONCLUSIONS: Severe PD is associated with all-cause and cause-specific mortality among US adults after multivariable adjustment.

Are there more women in the dentist workforce? Using an intersectionality lens to explore the feminization of the dentist workforce in the UK and US.

In this paper, we seek to understand feminization of the dentist workforce moving beyond previous research that has looked at gender in isolation. We contend that little consideration has been given to how gender interacts with other important social identities such as race/ethnicity to influence the opportunities and barriers that female dentists encounter during their dental career. We argue that the scholarly debate about the feminization of the dentistry has not acknowledged the intersectionality of women's lives. Intersectionality describes how multiple social identities (such as race/ethnicity, gender, and class) overlap and interact to inform outcomes, creating disadvantages and/or privileges. Our thesis is that the increasing feminization of the dentist workforce is complicated and paradoxical, creating both opportunities for women and gender imbalances and blockages within the profession. To support our thesis, we critically reviewed the literature on feminization and analysed UK and US workforce data. While the female dentist workforce in both the UK and the US has increased significantly over the past decade, the growth in the number of female dentists was not equal across all racial/ethnic groups. The largest increase in the number of female dentists was among White and Asian women. Viewing the feminization of the dentist workforce through an intersectionality lens exposes the multiple and complex experiences of women, as well as the power dynamics in dentistry. Feminization in dentistry demonstrates the importance of presence, privilege, and power. Based on our assessment of the dentist workforce, dentistry may be less inclusive, despite being perceived as more diverse. Further research should explore how power and privilege may operate in dentistry. Dentistry should embrace intersectionality to provide an inclusive evaluation of equity in the workforce.

A survey of dental services in England providing targeted care for people experiencing social exclusion: mapping and dimensions of access.

Introduction Poor oral health and barriers to accessing dental services are common among people experiencing social exclusion. This population experience a disproportionate and inequitable burden of oral disease. A small number of dental services have published models of care that target this population, but no national surveys have been conducted.Aims This study aims to identify what types of services are providing dental and oral healthcare for people experiencing social exclusion in England and the models of delivery adopted by these services.Methods A snowballing sampling strategy was used to identify services that provide targeted for adults experiencing social exclusion. The study used a survey to collect data about the location, service models and barriers and enablers of these services.Results In total, 74 responses from different services met the inclusion criteria for the study. Seventy one were included in the mapping exercise and 53 provided free-text comments that contributed to an understanding of barriers and enablers of services.Discussion Most services operated to meet the needs of the mainstream population and described inflexibilities in their service design models as barriers to providing care for socially excluded groups.Conclusion Limitations of current models of service delivery create frustrations for providers and people experiencing social exclusion. Creative commissioning and organisational flexibility are key to facilitating adaptable services.

A student-led qualitative study to explore dental undergraduates' understanding, experiences, and responses to racism in a dental school.

OBJECTIVES: This qualitative study explored dental student participants' understanding of racism, their experiences, and responses to racism in dental school, and the impacts of their experiences. METHODS: An interpretative phenomenological analysis design recruited students from the undergraduate dental degree and the BSc in Oral Health Science course at a UK dental school in December 2020. Two students and a qualitative researcher facilitated the online focus groups. A topic guide including scenario questions guided the discussions that lasted an average of 2 h. The recorded interviews were transcribed and analyzed using thematic analysis. RESULTS: Twenty-five participants took part in five focus groups. Several themes emerged related to participants' experiences and reactions. They described a spectrum of racist encounters ranging from more subtle forms, such as stereotyping and microaggression to racial mocking. They were concerned about professionalism, not knowing how and when to respond to patients' racist behavior. They described gender discrimination and intersectional biases but felt compelled to put patients' interests first. They were unsure about how to respond to stereotyping or racism from staff because of perceived imbalances in the staff-patient-student triad relationship. They expressed fears of gaslighting and despondency. They also felt that the COVID-19 pandemic and anonymity from virtual learning environments enabled racist behavior. CONCLUSION: This study revealed a complex triad relationship between participants, staff and patients, and experience of intersectionality and three levels of racism: interpersonal, structural, and institutional. It highlighted the need for further research to develop actions including structural policies and equality and diversity training.

Socioeconomic inequalities in the utilization of dental services among adults in Saudi Arabia.

BACKGROUND: This study used the Anderson Behavioral Model to assess the socioeconomic inequalities in dental services utilization among adults in Saudi Arabia, along with other predictors of utilization, to inform future planning of dental care services. METHODS: This cross-sectional study was a secondary analysis using national data from the 2019 Kingdom of Saudi Arabia World Health Survey (KSAWHS). The survey consisted of two interviewer-administered questionnaires: one household and one individual interview. The questions covered predisposing factors (age, gender, marital status, nationality, education, employment), enabling factors (income, household wealth, area-based socioeconomic class, health insurance, eligibility for free governmental health care, transportation and region of residence) and self-reported need for dental treatment. The main outcome was dental utilization in the past year; predisposing, enabling and need factors were independent variables. Hierarchical logistic regression analyses identified significant predictors of dental utilization, applying survey weights to adjust for the complex survey design. Adjusted odds ratios with 95% confidence intervals and p values were reported in the final model. RESULTS: The final dataset included 8535 adults (response rate = 95.4%). Twenty percent of adults had visited the dentist at least once in the past year (95% CI 18-21%). There were socioeconomic inequalities in dental utilization. High household income (OR 1.43, p = 0.043), second and middle household wealth status (OR 1.51, p = 0.003 and OR 1.57, p = 0.006) and access to free governmental health care (OR 2.05, p = 0.004) were significant predictors in the final regression model along with perceived need for dental treatment (OR 52.09, p < 0.001). CONCLUSION: Socioeconomic inequalities in the utilization of dental services exist in Saudi Arabia. The need for treatment was the strongest predictor suggesting predominantly symptomatic attendance. Increasing awareness about the importance of preventive dental visits rather than symptomatic attendance could be an important policy implication to improve oral health and optimize dental care expenditure. Further research should explore the drivers for adults to seek preventive care in the absence of any recognized dental problems.

Critically engaging vulnerability: Rethinking oral health with vulnerabilized populations.

This paper is the third in a series of narrative reviews challenging core concepts in oral health research and practice. Our series started with a framework for Inclusion Oral Health. Our second review explored one component of this framework, looking at how intersectionality adds important complexity to oral public health. This current manuscript drills into a second component of Inclusion Oral Health, exploring how labels can lead to 'othering' thereby misrepresenting populations and (re)producing harms. Specifically, we address a common oral public health label: vulnerable populations. This term is commonly used descriptively: an adjective (vulnerable) is used to modify a noun (population). What this descriptor conceals is the 'how,' 'why,' and 'therefore' that leads to and from vulnerability: How and why is a population made vulnerable; to what are they vulnerable; what makes them 'at risk,' and to what are they 'at risk'? In concealing these questions, we argue our conventional approach unwittingly does harm. Vulnerability is a term that implies a population has inherent characteristics that make them vulnerable; further, it casts populations as discrete, homogenous entities, thereby misrepresenting the complexities that people live. In so doing, this label can eclipse the strengths, agency and power of individuals and populations to care for themselves and each other. Regarding oral public health, the convention of vulnerability averts our research gaze away from social processes that produce vulnerability to instead focus on the downstream product, the vulnerable population. This paper theorizes vulnerability for oral public health, critically engaging its production and reproduction. Drawing from critical public health literature and disability studies, we advance a critique of vulnerability to make explicit hidden assumptions and their harmful outcomes. We propose solutions for research and practice, including co-engagement and co-production with peoples who have been vulnerabilized. In so doing, this paper moves forward the potential for oral public health to advance research and practice that engages complexity in our work with vulnerabilized populations.

A student and staff collaborative audit exploring the food and drinks available from a dental teaching hospital outlet.

Introduction NHS England's Commissioning for Quality and Innovation (CQUIN) standard 1b sets targets for food and drinks high in fat, sugar or salt (HFSS) that should be sold in hospitals.Aims To assess the products that were available in a dental hospital food outlet and to explore the cost and placement of HFSS products.Design and setting A prospective audit of the food outlet in a dental hospital in London, UK carried out by staff and students in May 2018 benchmarked against CQUIN 1b.Materials and methods Staff and students collected data on food and drinks that were available over a two-week period.Results Only cold and hot drinks met the CQUIN target that 80% of drinks should contain less than five grams of sugar/100 ml. A third of packaged biscuits and 50% of cakes and pastries contained more than 250 kcal per portion. HFSS products were visible in front of customers at the checkout till. Packaged fruits were more expensive than packaged biscuits.Discussion and conclusion This audit showed inconsistencies between the food and drinks available for staff, students and patients at a dental hospital and the healthy eating messages that staff and students relay to support patients' oral health.

What is intersectionality and why is it important in oral health research?

This paper is the second of two reviews that seek to stimulate debate on new and neglected avenues in oral health research. The first commissioned narrative review, "Inclusion oral health: Advancing a theoretical framework for policy, research and practice", published in February 2020, explored social exclusion, othering and intersectionality. In it, we argued that people who experience social exclusion face a "triple threat": they are separated from mainstream society, stigmatized by the dental profession, and severed from wider health and social care systems because of the disconnection between oral health and general health. We proposed a definition of inclusion oral health and a theoretical framework to advance the policy, research and practice agenda. This second review delves further into the concept of intersectionality, arguing that individuals who are socially excluded experience multiple forms of discrimination, stigma and disadvantage that reflect intersecting social identities. We first provide a theoretical and historical overview of intersectionality, rooted in Black feminist ideologies in the United States. Our working definition of intersectionality, requiring the simultaneous appreciation of multiple social identities, an examination of power and inequality, and a recognition of changing social contexts, then sets the scene for examining existing applications of intersectionality in oral health research. A critique of the sparse application of intersectionality in oral health research highlights missed opportunities and shortcomings related to paradigmatic and epistemological differences, a lack of robust theoretically engaged quantitative and mixed methods research, and a failure to sufficiently consider power from an intersectionality perspective. The final section proposes a framework to guide future oral health research that embraces an intersectionality agenda consisting of descriptive research to deepen our understanding of intersectionality, and transformative research to tackle social injustice and inequities through participatory research and co-production.

Community pharmacy staff oral health training, training needs and professional self-efficacy related to managing children's dental problems.

OBJECTIVES: Few studies have explored the oral health training needs and professional self-efficacy (PSE) in both pharmacy support staff and pharmacists related to managing children's dental problems. This study assessed community pharmacy staff perceptions of their (i) training experiences and interests; (ii) PSE; and (iii) whether this was influenced by the pharmacy being part of a minor ailment scheme (MAS), where staff could directly offer advice and issue prescription medications without patients seeing a doctor. METHODS: All of the 1851 community pharmacies across London, UK, were invited to participate in an online questionnaire. Staff rated their prior training, perceived need for further training and confidence in giving parents advice related to three dental problems in children (dental pain, mouth ulcers and dental trauma). Information was collected about staff roles and whether the pharmacy was a MAS. KEY FINDINGS: From 752 community pharmacies, 846 community pharmacy staff participated. Positive experiences of training were variable but interest in further training for all three dental problems was high. Pharmacy support staff had significantly lower PSE scores than pharmacy professionals (P = 0.009). A significant interaction showed that pharmacy staff who had poorly rated prior training on advising parents about managing their child's dental pain and who did not work in a MAS had lower PSE scores than staff who had highly rated training and who worked in a MAS (P = 0.02). CONCLUSIONS: Minor ailment scheme pharmacies may be an optimal environment for frontline pharmacy support staff to develop higher PSE when combined with good quality oral health training.

Relationships between children's sugar consumption at home and their food choices and consumption at school lunch.

OBJECTIVE: To investigate the relationships between children's food and drink choices at school lunch for children who consume high and low sugar intakes at home. DESIGN: Children's food and drink consumption at home was assessed using diet diaries over three consecutive days. Children were classified as 'high' or 'low' sugar consumers at home using the WHO recommendation that free sugars should be less than 10 % of their daily total energy intake. A purposive sample of children was then selected and observed during school lunch, recording food selections, food left on plates and content of packed lunches. SETTING: Six primary schools in Newham and Kent, England. PARTICIPANTS: Parents and children aged 6-7 years. RESULTS: Seventy-one parents completed diet diaries. From the seventy-one, thirty-nine children were observed during school lunch. Twenty children were high sugar consumers, nineteen children were low sugar consumers; thirty-one children had a school meal. Eleven of the fifteen children (73 %) who had school meals and who were high sugar consumers selected a high-sugar dessert rather than fruit. Only five of the sixteen (31 %) children who had school meals and were low sugar consumers at home chose a high-sugar dessert. Most of the children who had packed lunches had sweet items, despite school policies. CONCLUSIONS: Children who consumed high sugar intake at home tended to select foods high in sugar for school meals or had packed lunches containing high-sugar foods. The implications for public health programmes include healthy eating workshops and implementing school food policies.

Inclusion oral health: Advancing a theoretical framework for policy, research and practice.

In response to headlines about the oral health of persons experiencing social exclusion resonating in high-income countries, and research demonstrating the need for urgent action, a symposium entitled 'International Perspectives on Socially Inclusive Dentistry: A Call to Action' was organized for the IADR International Meeting of 2018. The aim of the symposium was to initiate an international dialogue on barriers to care, multidisciplinary action and examples of best practice for service delivery for people experiencing social exclusion; in other words, to develop the idea of inclusion oral health. Through our international exchange, what emerged was an awareness of a lack of professional consensus: What exactly is inclusion oral health? A theoretical framework to push forward the policy, research and practice agenda was clearly needed. This paper advances such a framework. Over the decades, dentistry has forged an approach to service delivery mainly through a business, demand-led model. While oral health continues to improve globally, an important consequence of this approach is that it compounds the social exclusion that many people are already experiencing because of a constellation of economic, political, cultural and individual factors. Thus, many people are simply not getting the dental care they need. In contrast, drawing on the theoretical literature on social exclusion, intersectionality and othering, we suggest that dentistry could act as an agent for social inclusion as a more responsive, all-encompassing form of oral health care and delivery. This paper advances a theoretical framework for inclusion oral health, and an action plan to show how inclusion oral health may become one solution in an armamentarium to tackle the global phenomena of oral health inequities.

Children's toothache is becoming everybody's business: where do parents go when their children have oral pain in London, England? A cross-sectional analysis.

OBJECTIVES: To assess the number of parents who visited community pharmacies in London seeking pain medications for their children's pain and specifically for oral pain, to identify which health services parents contacted before their pharmacy visit and to estimate the cost to the National Health Service (NHS) when children with oral pain who visit pharmacies also see health professionals outside dentistry. DESIGN: A cross-sectional study. SETTING: 1862 pharmacies in London in November 2016-January 2017. PARTICIPANTS: Parents, carers and adolescents purchasing over-the-counter pain medications or collecting pain prescriptions for children (0-19 years). BRIEF INTERVENTION: A survey administered by pharmacy staff to participants and a guidance pack. MAIN OUTCOME MEASURES: The number of parents who visited pharmacies seeking pain medications for their children's pain and oral pain and the number of parents who contacted health professionals outside dentistry before their pharmacy visit. Estimated costs of visits by children with oral pain to health professionals outside dentistry. RESULTS: One in two (951) pharmacies participated collecting information from 6915 parents seeking pain medications for their children. The majority (65%) of parents sought pain medications to relieve their children's oral pain. Only 30% of children with oral pain had seen a dentist before the pharmacy visit, while 28% of children had seen between one and four different health professionals. The cost to the NHS of children contacting health professionals outside dentistry was £36 573, extrapolated to an annual cost of £373 288. Replicating these findings across all pharmacies in England could mean that the NHS spends an estimated £2.3 million annually when children with oral pain inappropriately use multiple health services. CONCLUSION: Most parents who visited pharmacies for children's pain medications in London sought pain medications for children's oral pain. Children's inappropriate contact with multiple health services when they have oral pain adds significant costs to the NHS.

How do foster carers manage the oral health of children in foster care? A qualitative study.

OBJECTIVES: This qualitative study explored how the foster family environment influenced children's oral health. It also aimed to better understand foster carers' oral health knowledge, attitudes and experiences of managing foster children's oral health behaviours and oral health care. METHODS: An interpretative phenomenological analysis (IPA) study design was used to recruit a purposive sample of foster carers in Tower Hamlets, United Kingdom, from a range of backgrounds (maximum variation sampling). Participants were aged 21 years and older and provided full-time foster care for children for a minimum of 1 year. The foster carers took part in focus groups that were audio-recorded and transcribed verbatim. Data analysis followed a five-step IPA process, which included reading the transcripts, note taking, identifying emerging themes, connecting related themes and writing up the final themes. Iterative data gathering and analysis continued to reach thematic saturation. RESULTS: Three focus groups were conducted, involving a total of 12 foster carers. Eight of the 12 participants had fostered children for more than 10 years and they were currently fostering 22 children aged five to 18 years old. Four themes emerged from within the context of the supportive and nurturing foster family environment that described how foster carers' responded to and managed the oral health of their foster children. Foster carers had adopted an oral health caregiving role, "in loco parentis" responding to the poor oral health of their vulnerable foster children. They were hypervigilant about establishing and monitoring children's oral health routines and taking their children to see a dentist; these were seen as an integral part of being good foster carers. They were knowledgeable about the causes of children's oral ill health, gained from their own dental experiences and from looking after their own children. Foster carers had experienced tensions while adopting this oral health caregiving role with dentists who had refused to see younger children. Foster carers had also experienced tensions with teenage foster children who questioned their parental authority and legitimate right to set rules about smoking and healthy eating. CONCLUSIONS: This is the first study to explore foster carers' oral health perspectives and the foster family environment within the oral health context. It highlights the unrecognized and important role that foster carers have in improving the oral health of vulnerable children. Further research is needed to explore the relationship between foster carers and dentists and to support the development of health and social care interventions to improve foster children's oral health.

A new primary dental care service compared with standard care for child and family to reduce the re-occurrence of childhood dental caries (Dental RECUR): study protocol for a randomised controlled trial.

BACKGROUND: In England and Scotland, dental extraction is the single highest cause of planned admission to the hospital for children under 11 years. Traditional dental services have had limited success in reducing this disease burden. Interventions based on motivational interviewing have been shown to impact positively dental health behaviours and could facilitate the prevention of re-occurrence of dental caries in this high-risk population. The objective of the study is to evaluate whether a new, dental nurse-led service, delivered using a brief negotiated interview based on motivational interviewing, is a more cost-effective service than treatment as usual, in reducing the re-occurrence of dental decay in young children with previous dental extractions. METHODS/DESIGN: This 2-year, two-arm, multicentre, randomised controlled trial will include 224 child participants, initially aged 5 to 7 years, who are scheduled to have one or more primary teeth extracted for dental caries under general anaesthesia (GA), relative analgesia (RA: inhalation sedation) or local anaesthesia (LA). The trial will be conducted in University Dental Hospitals, Secondary Care Centres or other providers of dental extraction services across the United Kingdom. The intervention will include a brief negotiated interview (based on the principles of motivational interviewing) delivered between enrollment and 6 weeks post-extraction, followed by directed prevention in primary dental care. Participants will be followed up for 2 years. The main outcome measure will be the dental caries experienced by 2 years post-enrollment at the level of dentine involvement on any tooth in either dentition, which had been caries-free at the baseline assessment. DISCUSSION: The participants are a hard-to-reach group in which secondary prevention is a challenge. Lack of engagement with dental care makes the children and their families scheduled for extraction particularly difficult to recruit to an RCT. Variations in service delivery between sites have also added to the challenges in implementing the Dental RECUR protocol during the recruitment phase. TRIAL REGISTRATION: ISRCTN24958829 (date of registration: 27 September 2013), Current protocol version: 5.0.

Do health provider-patient relationships matter? Exploring dentist-patient relationships and oral health-related quality of life in older people.

BACKGROUND: patient experience is now a key parameter in health care. Yet, very little is known about the possible impact of dentist-patient relationships on patient-centred outcomes including older peoples' oral health-related quality of life (OHRQoL). OBJECTIVE: this study assessed the relationship between OHRQoL and dentist-patient relationships related to perceived unmet dental needs; shared decision-making; time spent discussing oral health problems; respect and confidence and trust. PARTICIPANTS: older people aged 65 years and over living in East London, U.K. in 2011. METHODS: a cross-sectional study using stratified random sampling recruited a representative sample of older people (n = 772). PARTICIPANTS completed an oral examination and a structured questionnaire including the Oral Health Impact Profile-14 (OHIP-14) measuring OHRQoL and five dentist-patient relationship questions taken from the U.K. 2009 Adult Dental Health Survey. Multivariate Poisson regressions modelled the association between OHRQoL and dentist-patient factors adjusting for socio-demographic factors, clinical oral indicators, and dental attendance. RESULTS: having a perceived unmet need for dental treatment (PRR = 1.84; 95% CI: 1.32, 2.56) and expressing a lack of trust and confidence in one's dentist (PRR = 1.74; 95% CI: 1.01, 2.98) were significant predictors of poor OHRQoL among older people. CONCLUSIONS: these findings suggest that older people with unmet dental needs and those who expressed a lack of trust and confidence in their dentist were more likely to experience poor OHRQoL reinforcing the importance of the dental patient experience in healthy ageing and well-being.

Life course experiences and lay diagnosis explain low-income parents' child dental decisions: a qualitative study.

OBJECTIVE: This study aimed to better understand low-income parents' child dental care decisions through a life course approach that captured parents' experiences within the social context of poverty. METHODS: We conducted 43 qualitative life history interviews with 10 parents, who were long-term social assistance recipients living in Montreal, Canada. Thematic analysis involved interview debriefing, transcript coding, theme identification and data interpretation. RESULTS: Our interviews identified two emergent themes: lay diagnosis and parental oral health management. Parents described a process of 'lay diagnosis' that consisted of examining their children's teeth and interpreting their children's oral signs and symptoms based on their observations. These lay diagnoses were also shaped by their own dental crises, care experiences and oral health knowledge gained across a life course of poverty and dental disadvantage. Parents' management strategies included monitoring and managing their children's oral health themselves or by seeking professional recourse. Parents' management strategies were influenced both by their lay diagnoses and their perceived ability to manage their children's oral health. Parents felt responsible for their children's dental care, empowered to manage their oral health and sometimes forgo dental visits for their children because of their own self-management life history. CONCLUSION: This original approach revealed insights that help to understand why low-income parents may underutilize free dental services. Further research should consider how dental programs can nurture parental empowerment and capitalize on parents' perceived ability to diagnose and manage their children's oral health.

Exploring school oral health outcomes and neighbourhood factors in schools participating in Ontario's "Healthy Schools" recognition program.

OBJECTIVES: This ecologic study compared school-level oral health outcomes in schools participating in Ontario's "Healthy Schools" program and nonparticipating schools in York Region, Ontario in 2007-2008 and examined the effect of neighbourhood socio-economic factors. METHOD: School-aggregated data were obtained for all 243 elementary schools. York Region Public Health Unit provided oral health data from school dental screenings. We obtained information about schools participating in the Ontario's "Healthy Schools" program from publicly accessible websites. Neighbourhood socio-economic data based on school postcodes were extracted from Statistics Canada (2006) census databases. School oral health outcomes included the percentage of children in each school requiring preventive care, non-urgent dental treatment, urgent dental treatment and children with > or = two decayed teeth. RESULTS: One hundred and six elementary schools (42%) participated in Ontario's "Healthy Schools" program in 2007-2008. Schools participating in the "Healthy Schools" program had a significantly lower percentage of children with > or = two decayed teeth (p < 0.001) and children requiring urgent dental treatment (p = 0.004) than non-participating schools. School participation/neighbourhood socio-economic factors interactions showed that a significantly lower percentage of children in low-income "Healthy Schools" had preventive and urgent dental treatment needs and > or = two decayed teeth than in low-income non-participating schools (p < 0.001). CONCLUSION: Schools participating in Ontario's "Healthy Schools" program had better school oral health outcomes than non-participating schools. School neighbourhood socio-economic factors affected school oral health outcomes, which could suggest that schools situated in poorer neighbourhoods may benefit more from health promotion activities than schools situated in more affluent neighbourhoods.

Does psychological well-being influence oral-health-related quality of life reports in children receiving orthodontic treatment?

INTRODUCTION: Although the associations between oral biologic variables such as malocclusion and oral-health-related quality of life (OHRQOL) have been explored, little research has been done to address the influence of psychological characteristics on perceived OHRQOL. The aim of this study was to assess OHRQOL outcomes in orthodontics while controlling for individual psychological characteristics. We postulated that children with better psychological well-being (PWB) would experience fewer negative OHRQOL impacts, regardless of their orthodontic treatment status. METHODS: One hundred eighteen children (74 treatment and 44 on the waiting list), aged 11 to 14 years, seeking treatment at the orthodontic clinics at the University of Toronto, participated in this study. The child perception questionnaire (CPQ11-14) and the PWB subscale of the child health questionnaire were administered at baseline and follow-up. Occlusal changes were assessed by using the dental aesthetic index. A waiting-list comparison group was used to account for age-related effects. RESULTS: Although the treatment subjects had significantly better OHRQOL scores at follow-up, the results were significantly modified by each subject's PWB status (P <0.01). Furthermore, multivariate analysis showed that PWB contributed significantly to the variance in CPQ11-14 scores (26%). In contrast, the amount of variance explained by the treatment status alone was relatively small (9%). CONCLUSIONS: The results of this study support the postulated mediator role of PWB when evaluating OHRQOL outcomes in children undergoing orthodontic treatment. Children with better PWB are, in general, more likely to report better OHRQOL regardless of their orthodontic treatment status. On the other hand, children with low PWB, who did not receive orthodontic treatment, experienced worse OHRQOL compared with those who received treatment. This suggests that children with low PWB can benefit from orthodontic treatment. Nonetheless, further work, with larger samples and longer follow-ups, is needed to confirm this finding and to improve our understanding of how other psychological factors relate to patients' OHRQOL.

Oral health disparities and food insecurity in working poor Canadians.

OBJECTIVES: This study explored oral health disparities associated with food insecurity in working poor Canadians. METHODS: We used a cross-sectional stratified study design and telephone survey methodology to obtain data from 1049 working poor persons aged between 18 and 64 years. The survey instrument contained sociodemographic items, self-reported oral health measures, access to dental care indicators (dental visiting behaviour and insurance coverage) and questions about competing financial demands. Food-insecure persons gave 'often' or 'sometimes' responses to any of the three food insecurity indicators used in the Canadian Community Health Survey (2003) assessing 'worry' about not having enough food, not eating enough food and not having the desired quality of food because of insufficient finances in the previous 12 months. RESULTS: Food-insecure working poor persons had poor oral health compared with food-secure working poor persons indicated by a higher percentage of denture wearers (P < 0.001) and a higher prevalence of toothache, pain and functional impacts related to chewing, speaking, sleeping and work difficulties (P < 0.001). Fewer food-insecure persons rated their oral health as good or very good (P < 0.001). Logistic regression analyses showed that oral health disparities between food-insecure and food-secure persons related to denture wearing, having a toothache, reporting poor/very poor self-rated oral health or experiencing an oral health impact persisted after adjusting for sociodemographic factors and access to dental care factors (P < 0.05). Food-insecure working poor persons reported relinquishing goods or services in order to pay for necessary dental care. CONCLUSIONS: This study identified oral health disparities within an already marginalized group not alleviated by access to professional dental care. Working poor persons regarded professional dental care as a competing financial demand.
