Self-reported oral health at baseline of the Canadian Longitudinal Study on Aging.

OBJECTIVES: To compare the prevalence of poor self-reported oral health (SROH) and dental service-use in a representative sample of Canadian residents, and to identify associations between SROH and psychosocial determinants of health at baseline of the Canadian Longitudinal Study on Aging. METHODS: Data from baseline interviews from 2010 to 2015 involving 93% of 51 388 adults (n = 47 761) were weighted to compare the prevalence of oral health characteristics adjusted for age, sex, socioeconomics, general health and residence. SROH was assessed as 'excellent', 'very good', 'good', 'fair' or 'poor', and dichotomized as 'fair/poor' and 'good/very good/excellent'. Multivariable logistic regression was used to assess the association of fair/poor oral health with psychosocial determinants of health. RESULTS: Most participants reported 'good/very good/excellent' oral health (92.5%), natural teeth (92.0%) and dental service-use in the previous year (79.6%), yet over 10% had discomfort when eating. Reports of 'fair/poor' oral health were significantly more frequent among participants who had dental concerns, had low socioeconomic status, smoked tobacco or reported poor general health. Dental service-use and tooth loss differed by province. The odds of poor/fair SROH were high (odds ratio ≥1.5) among participants who avoided foods, did not use dental services frequently, had low incomes, smoked tobacco, were depressed, felt unhealthy or had multiple chronic conditions, but by neither sex or age. There were no interprovincial differences. CONCLUSIONS: Most Canadian residents feel in good oral health and use dental services. Oral health inequality is evident between different socioeconomic groups and between healthy and unhealthy people. SROH is strongly associated with socioeconomic and general health status but not with place of residence. However, there were substantial differences in reports of tooth loss and dental service-use across provinces.

Developmental regulation of lifelong dental experiences and beliefs in Guangzhou and Hong Kong.

AIMS: The aim of this study was to explain through the life-course and life-span perspectives of developmental regulation theory the controls on dental experiences and beliefs throughout the lives of older people in Guangzhou and Hong Kong. BACKGROUND: Dental diseases and disabilities among older people are serious public health concerns in China. METHODS: A facilitator conducted eight focus groups, three in Hong Kong and five in Guangzhou, involving a total of 51 participants. She encouraged discussions about lifetime events to explain dental experiences and beliefs. Transcripts were coded and analysed using a constant comparative approach to identify themes that explained the regulators of dental experiences throughout the participants' lives. RESULTS: Participants explained the influence of culture and history through critical events, and how external and internal factors regulated their current oral health status and beliefs. They emphasised the role of Traditional Chinese Medicine and family, and the stress of social upheaval compounded by a scarcity of dental services. They revealed also how current choice of dental services and health promotional programs, helped by personal food choice, self-reliance, and scepticism, helped them to adjust and cope with dental diseases and disabilities and the commercialisation of dental services. CONCLUSIONS: Dental experiences and beliefs of older people living in Guangzhou and Hong Kong were regulated strongly during personal development by culture and history during critical events, and by various controlling factors, such as health promotion and choice of services supplemented by food choice, nutritional balance, self-reliance, scepticism and social adjustments.

The perceptions of first nation participants in a community oral health initiative.

The Children's Oral Health Initiative (COHI) is a federally funded community-based preventive dental program for children and their caregivers living in geographically isolated Canadian Aboriginal communities. The goal of the program is to improve access to preventive dental services for children of 0-7 years of age. It utilises community health workers in collaboration with dental therapists to promote and deliver the program. Almost half of the province of Manitoba's (n=27) First Nations communities have implemented COHI since 2005. The objective of this investigation was to explore the opinions of COHI from the perspective of community members whose children had participated in the program. Purposeful selection identified caregivers of enrolled children for a semi-structured interview. The targeted caregivers had children who met at least one of the following criteria: (1) 0-2 years old; (2) 5-7 years old; (3) had two or more children either currently or formerly enrolled in COHI. Six open-ended questions guided the interview process. Content analysis was used to code transcripts and identify themes. One hundred and forty-one interviews were completed in 13 communities. Participants defined good oral health as the absence of dental cavities, which reflects a Western biomedical model of disease. The local, community-based nature of COHI was viewed as essential to its success in increasing access to preventive dental services and improving children and caregivers' oral health knowledge and behaviours. In conclusion, a local, community-based oral health prevention programme is perceived as having a beneficial effect on children and caregivers' oral health knowledge and behaviours. However, oral health preventive messages need to be further integrated into traditional Aboriginal holistic models of wellness.

Community dental clinics in British Columbia, Canada: examining the potential as health equity interventions.

Community dental clinics (CDCs) have emerged to provide oral healthcare for those with low incomes. In British Columbia, the establishment of community clinics has been quite rapid in recent years. However, the expansion has occurred with very little assessment of their impact or effectiveness. While oral health inequities are well recognised, there is limited documentation on healthcare interventions to reduce oral health inequities. This study examines CDCs as health equity interventions from the perspectives of individuals establishing and operating the clinics. The study included interviews with 17 participants--4 dentists, 6 dental hygienists and 7 clinic managers--from 10 clinics operating in British Columbia, Canada in 2008-2009. A thematic analysis of the interview transcripts, explored through a health equity framework, found many ways in which the CDCs exemplify health equity interventions. Although their design and mandates are varied, they potentially enable access to dental treatment, but without necessarily ensuring sustainable outcomes. Moreover, the scalability of CDCs is questionable because frequently they are limited to emergency care and are less responsive to the gradients of needs for populations facing multiple barriers to care. Many of them operate on a charitable base with input from volunteer dentists; however, this foundation probably eases the pressure on dentists and dental hygienists rather than offering a safety net to underserved populations.

Inequity in oral health care for elderly Canadians: part 2. Causes and ethical considerations.

The Canadian Health Measures Survey, conducted between March 2007 and February 2009, revealed unmet dental needs among older adults in Canada. This article, the second of a 3-part series, explains that the inequity in oral care faced by elderly Canadians is due largely to the current fee-for-service dental service system. However, the inequity has arisen because of financial, behavioural and physical barriers, and both the community at large and the dental profession have a social responsibility to reduce this unfairness and provide equitable access to oral care for older people.

Perspectives on community dental clinics and oral health inequities in British Columbia.

BACKGROUND: This study investigates the expansion of community dental clinics to address oral health inequities in the province of British Columbia (BC) from the perspectives of dental professionals and allied service-providers. METHODS: Sixty-three people participated in individual and group interviews with dentists (n=4), dental hygienists (n=30), dental clinic staff (n=17), and other health care and social service providers (n=12). RESULTS: We identified two service-models: a volunteer-charitable (VC) model typically operating part-time mostly to relieve pain and a not-for-profit (NFP) model open full-time usually within a community health centre with paid staff providing basic dental services. CONCLUSIONS: Community dental clinics are increasing in number to fill a gap in the oral health care of disadvantaged people in BC. Staff in these clinics raised questions indirectly about distributive justice and health care inequity by suggesting that the unmet dental need of vulnerable people requires political attention and that restricted dentistry for underserved communities is socially unacceptable.

The economics of dentistry: a neglected concern.

BACKGROUND: Demand for economic evaluations in health care is growing with expectations that they will help to develop regional and national policies on health and social programmes. We present here the scope, quality and content of systematic reviews and meta-analyses relating to the economics of dentistry published over the last 15 years. OBJECTIVES: To review the quality and outcome of systematic reviews and meta-analyses relating to the economics of dental treatments, preventions and services. METHODS: A systematic search was conducted in 14 electronic databases for systematic reviews and meta-analyses published between January 1997 and July 2011 on the economics of oral disorders and oral health care. Review papers were extracted by two independent investigators to identify the characteristics, results and quality of the reviews and to highlight gaps in knowledge about the economics of dentistry. RESULTS: From 3150 unique references, we found 73 systematic reviews or meta-analyses of dental economics as primary or secondary outcomes. The focus of 12 of them was on the cost or cost-effectiveness of dental prevention, 54 on treatment, five on prevention and treatment and two on delivery of dental services. However, only 12 of the systematic reviews drew conclusions from economic data, and four of them constructed an economic model from synthesized data. Overall, the quality was good in the 12 systematic reviews but poor in the original studies. CONCLUSIONS: There is very little helpful data published on the economics of dentistry.

The influence of culture on the oral health-related beliefs and behaviours of elderly chinese immigrants: a meta-synthesis of the literature.

Neglect of the mouth can lead to impairment, disability, and discomfort; as a result, it can have a negative impact on quality of life in old age. Some minority groups in North America shoulder a disproportionate burden of dental impairment compared to people of European origins, possibly because of different cultural beliefs and a distrust of Western oral healthcare. This paper explores these factors in elderly Chinese immigrants through a meta-synthesis of selected literature that reveals a dynamic interplay of traditional Chinese beliefs about oral health, immigration, and structural factors mediating access to Western dentistry. It also identifies several conceptual issues and gaps in knowledge, offers avenues of research including the cross-cultural application of two recent models of oral health, and discusses various strategies for improving access to dental services for minority populations.

Inequity in oral health care for elderly Canadians: part 1. Oral health status.

Oral health is a contributory factor to general well-being and quality of life. The Canadian Health Measures Survey between March 2007 and February 2009, documented the oral problems that elderly people experience. This age group faces inequity in oral health care (especially in a fee-for-service system) and the aging of the Canadian population will exacerbate the problem of inequity. This article, the first of a 3-part series, discusses the impact of poor oral health on elderly people. The second article will consider inequity in terms of the financial, behavioural and physical barriers within the Canadian health care system, as well as ethical considerations related to this inequity, and the third will provide suggestions to overcome the barriers.

Community dental clinics: providers' perspectives.

OBJECTIVES: Not-for-profit community dental clinics attempt to address the inequities of oral health care for disadvantaged communities, but there is little information about how they operate. The objective of this article is to explain from the perspective of senior staff how five community dental clinics in British Columbia, Canada, provide services. METHODS: The mixed-methods case study included the five not-for-profit dental clinics with full-time staff who provided a wide range of dental services. We conducted open-ended interviews to saturation with eight senior administrative staff selected purposefully because of their comprehensive knowledge of the development and operation of the clinics and supplemented their information with a year's aggregated data on patients, treatments, and operating costs. RESULTS: The interview participants described the benefits of integrating dentistry with other health and social services usually within community health centres, although they doubted the sustainability of the clinics without reliable financial support from public funds. Aggregated data showed that 75% of the patients had either publically funded or no coverage for dental services, while the others had employer-sponsored dental insurance. Financial subsidies from regional health authorities allowed two of the clinics to treat only patients who are economically vulnerable and provide all services at reduced costs. Clinics without government subsidies used the fees paid by some patients to subsidize treatment for others who could not afford treatment. CONCLUSIONS: Not-for-profit dental clinics provide dental services beyond pain relief for underserved communities. Dental services are integrated with other health and community services and located in accessible locations. However, all of the participants expressed concerns about the sustainability of the clinics without reliable public revenues.

Discussions on oral health care among elderly Chinese immigrants in Melbourne and Vancouver.

BACKGROUND: This study explored how elderly Chinese immigrants value and relate to how acculturation influences oral health and subsequent service use. METHODS: Elders who had immigrated to Melbourne and Vancouver within the previous 15 years were recruited from local community centres and assigned to focus groups of 5-7 participants in Vancouver (4 groups) or Melbourne (5 groups). RESULTS: Following an iterative process of thematic analysis, the discussions revealed that immigrants care about the comfort and appearance of their teeth, and they value Western dentistry as a supplement to traditional remedies, but they have difficulty getting culturally sensitive information about oral health care. Accessing dentistry, they explained, is distressing because of language problems and financial costs that impose on their children. Consequently, many immigrants obtain dental treatment in China when they return for occasional visits. They felt that separation of dentistry from national health care programmes in Canada and Australia disregards natural links between oral health and general health. CONCLUSIONS: The similarity of concerns in both cities suggests that dissemination of information and availability of services are the important themes influencing oral health, and that, beliefs developed over a lifetime play an important role in interpreting oral health in the host country.

Access to dental care for low-income adults: perceptions of affordability, availability and acceptability.

The objective of this study was to explore access to dental care for low-income communities from the perspectives of low-income people, dentists and related health and social service-providers. The case study included 60 interviews involving, low-income adults (N = 41), dentists (N = 6) and health and social service-providers (N = 13). The analysis explores perceptions of need, evidence of unmet needs, and three dimensions of access--affordability, availability and acceptability. The study describes the sometimes poor fit between private dental practice and the public oral health needs of low-income individuals. Dentists and low-income patients alike explained how the current model of private dental practice and fee-for-service payments do not work well because of patients' concerns about the cost of dentistry, dentists' reluctance to treat this population, and the cultural incompatibility of most private practices to the needs of low-income communities. There is a poor fit between private practice dentistry, public dental benefits and the oral health needs of low-income communities, and other responses are needed to address the multiple dimensions of access to dentistry, including community dental clinics sensitive to the special needs of low-income people.

A scoping review and research synthesis on financing and regulating oral care in long-term care facilities.

BACKGROUND: Oral health care for frail elders is grossly inadequate almost everywhere, and our knowledge of regulating and financing oral care in this context is unclear. OBJECTIVE: This scoping study examined and summarised the published literature available and the gaps in knowledge about regulating and financing oral care in long-term care (LTC) facilities. METHODS: We limited the electronic search to reports on regulating and financing oral care, including reports, commentaries, reviews and policy statements on financing and regulating oral health-related services. RESULTS: The broad electronic search identified 1168 citations, which produced 42 references, including 26 pieces of grey literature for a total of 68 papers. Specific information was found on public and private funding of care and on difficulties regulating care because of professional segregation, difficulties assessing need for care, uncertainty on appropriateness of treatments and issues around scope of professional practice. A wide range of information along with 19 implications and 18 specific gaps in knowledge emerged relevant to financing and regulating oral healthcare services in LTC facilities. CONCLUSIONS: Effort has been given to enhancing oral care for frail elders, but there is little agreement on how the care should be regulated or financed within the LTC sector.

A randomized clinical trial comparing patient satisfaction and prosthetic outcomes with mandibular overdentures retained by one or two implants.

PURPOSE: This randomized clinical trial tested hypotheses that there are no differences in patient satisfaction, component costs, or treatment and maintenance times when mandibular overdentures are retained by one or two implants. MATERIALS AND METHODS: Subjects wearing conventional complete dentures were randomized to receive either one midline or two bilateral mandibular implants followed by a mandibular denture reline to incorporate implant retention. They indicated on a visual analog scale satisfaction with their dentures before implants and at 2 months and 1 year after implant retention. Satisfaction outcomes between the two groups were compared using the Wilcoxon/Mann-Whitney nonparametric rank test, while changes within each group were analyzed using signed-rank tests. Component costs and times for surgery, prosthodontic treatment, and maintenance were compared using nonparametric and t tests. RESULTS: Eighty-six subjects enrolled in this study and 85 completed the 1-year follow-up, at which median satisfaction was 93 (maximum 100) in the single-implant group and 94 in the two-implant group (P > .5). Within each group, median improvement in satisfaction was similarly dramatic (approximately 44) and significant (P < .001). Prosthodontic maintenance time was similar for both groups (P > .37), but the single-implant group had significantly lower component costs (P < .001) and lower times for surgery (P = .002), postsurgical denture maintenance (P = .021), and denture reline (P < .001). Five implants failed in four subjects, all in the two-implant group and all before denture reline. CONCLUSION: Lower component costs and treatment times, with comparable satisfaction and maintenance time over the first year, indicate that a mandibular overdenture retained by a single midline implant may be an alternative to the customary two-implant overdenture for maladaptive denture patients.

Screening and enrolling subjects in a randomized clinical trial involving implant dentures.

PURPOSE: When planning and budgeting for a clinical trial, researchers have few references to help them estimate how many volunteers will need to be screened, how long the screening process may take, and how much it may cost to enroll sufficient qualified subjects. The purpose of this study was to analyze the time and costs involved in recruiting, screening, and enrolling subjects for a randomized clinical trial examining patient satisfaction with mandibular dentures retained by 1 or 2 implants. MATERIALS AND METHODS: Data collected included age and sex of volunteers, recruiting sources, length of time and costs of recruiting and screening volunteers, and reasons for inclusion or exclusion. Results were analyzed using Pearson chi-square tests. RESULTS: We estimated that we would need to screen 180 volunteers over a period of 4 years at an estimated total cost of CAN$47,664.00 to enroll 86 subjects. Instead, we had to screen 220 volunteers at a direct cost of $63,324.81. We excluded 28% of volunteers, while 32% declined participation and 40% agreed to participate in the study. Volunteers were most commonly excluded because of technical problems with their existing dentures, while they were most likely to decline participation because of perceived surgical risks with implants. Those who agreed to participate most commonly cited anticipation of a more secure mandibular denture as their reason for enrolling. CONCLUSION: We had to screen more volunteers at a higher cost than anticipated, with only 40% of those screened meeting inclusion criteria and agreeing to participate in the trial.

How dentists account for social responsibility: economic imperatives and professional obligations.

This study explores how dentists explain the concept of social responsibility and its relationship to issues affecting access to oral health care by vulnerable segments of the population. Analysis of open-ended interviews with thirty-four dentists, including dental educators, and administrators and officials of dental public health programs in Canada and the United States revealed that four main themes-economics, professionalism, individual choice, and politics-influenced the respondents' sense of social responsibility in dentistry. There was a belief that social responsibility in dentistry is dominated by economic imperatives that impact negatively on the policies and practices directing access to care. Yet, despite the highly critical stance on dentistry as a business, there was practical recognition of the economic realities of dental practice. Nevertheless, those who focused on social responsibility as a professional obligation highlighted the privileges of self-governance along with the accompanying duty to serve the welfare of everyone and not just those who are socioeconomically advantaged.

Elders assessment of an evolving model of oral health.

OBJECTIVES: To evaluate qualitatively a model of oral health through focus groups among elders. METHODS: The participants (30 women and 12 men; mean age: 75 years) attended one of six focus groups to discuss the relevance of the model to their oral health-related beliefs and experiences, and transcripts of the narratives were analysed systematically for the components, associations and recommendations emerging from the discussions. RESULTS: The groups confirmed the relevance of the original components of the model with minor modifications, but felt that for completeness it required four additional components: diet; economic priorities; personal expectations; and health values and beliefs. They recommended that the negative connotations of limited activity, impairment and restricted participation were modified with the positive terms activity and participation, and they suggested that ellipses rather than concentric circles more aptly illustrate the dynamic and overlapping importance of the various components in the model. CONCLUSION: The original model required additional components and graphic representation to accommodate all of the experiences and beliefs relating to the oral health of the elders who participated in this qualitative study.

Predictors of oral health quality of life in older adults.

There is limited information regarding oral health status and other predictors of oral health-related quality of life. An association between oral health status and perceived oral health-related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low-income elders (mean age 72.7 [SD = 4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four-year assessment had an average of 21.5 teeth (SD = 6.9), with 8.5 occluding pairs (SD = 4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign-born. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21% in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.
