Little attention has been given to the issue of the age of onset of dental anxiety, even though it may have a bearing on the origins of this type of fear. This study aimed to identify the age of onset of dental anxiety and to identify differences by age of onset with respect to potential etiological factors, such as negative dental experiences, family history of dental anxiety, and general psychological states. Data were collected by means of two mail surveys of a random sample of the adult population. Of 1420 subjects returning questionnaires, 16.4% were dentally anxious. Half, 50.9%, reported onset in childhood, 22.0% in adolescence, and 27.1% in adulthood. Logistic regression analyses indicated that negative dental experiences were predictive of dental fear regardless of age of onset. A family history of dental anxiety was predictive of child onset only. Adolescent-onset subjects were characterized by trait anxiety and adult-onset subjects by multiple severe fears and symptoms indicative of psychiatric problems. The three groups were similar in terms of their physiological, cognitive, and behavioral responses to dental treatment. However, adolescent- and adult-onset subjects were more hostile toward and less trusting of dentists. These results indicate that child-onset subjects were more likely to fall into the exogenous etiological category suggested by Weiner and Sheehan (1990), while adult-onset subjects were more likely to fall into the endogenous category.

BackgroundThe purpose of this study was to quantify time loss due to dental problems and treatment in the Canadian population, to identify factors associated with this time loss, and to provide information regarding the economic impacts of these issues.MethodsData from the 2007/09 Canadian Health Measures Survey were used. Descriptive analysis determined the proportion of those surveyed who reported time loss and the mean hours lost. Linear and logistic regressions were employed to determine what factors predicted hours lost and reporting time loss respectively. Productivity losses were estimated using the lost wages approach.ResultsOver 40 million hours per year were lost due to dental problems and treatment, with a mean of 3.5 hours being lost per person. Time loss was more likely among privately insured and higher income earners. The amount of time loss was greater for higher income earners, and those who reported experiencing oral pain. Experiencing oral pain was the strongest predictor of reporting time loss and the amount of time lost.ConclusionsThis study has shown that, potentially, over 40 million hours are lost annually due to dental problems and treatment in Canada, with subsequent potential productivity losses of over $1 billion dollars. These losses are comparable to those experienced for other illnesses (e.g., musculoskeletal sprains). Further investigation into the underlying reasons for time loss, and which aspects of daily living are impacted by this time loss, are necessary for a fuller understanding of the policy implications associated with the economic impacts of dental problems and treatment in Canadian society.
ObjectiveTo explore trends in access to dental care among middle-income Canadians.MethodsA secondary data analysis of six Canadian surveys that collected information on dental insurance coverage, cost-barriers to dental care, and out-of-pocket expenditures for dental care was conducted for select years from 1978 to 2009. Descriptive analyses were used to outline and compare trends among middle-income Canadians with other levels of income as well as national averages.ResultsBy 2009, middle-income Canadians had the lowest levels of dental insurance coverage (48.7%) compared to all other income groups. They reported the greatest increase in cost-barriers to dental care, from 12.6% in 1996 to 34.1% by 2009. Middle-income Canadians had the largest rise in out-of-pocket expenditures for dental care since 1978.ConclusionsThis study suggests that affordability issues in accessing dental care are no longer just a problem for the lowest income groups in Canada, but are now impacting middle-income earners as a consequence of their lack of, or decreased access to, comprehensive dental insurance.
Persons with disabilities (PWDs) have a disproportionate level of dental disease relative to the general population. Access to care is a cause along with dentists' willingness to treat PWDs. The aim of this study was to investigate the expectations and experiences of dental students in providing treatment to these patients in a hospital-based dental clinic for PWDs. Senior dental students at the Faculty of Dentistry, University of Toronto (n=92) were surveyed prior to (Phase I) and at the end of (Phase II) mandatory clinical rotations at the Mount Sinai Hospital's Dentistry Clinic for Persons with Special Needs. Response rates were 88% for Phase I and 58% for Phase II. Before the rotations, 70% of the respondents reported little or no experience with PWDs, and 46% said they did not feel comfortable providing basic dental treatment to PWDs. However, in Phase II, significantly more students reported being comfortable than in Phase I (p=0.001). Overall, the majority of respondents (Phase I 95%; Phase II 98%) indicated they would at least attempt to provide basic dental care to PWDs after graduation. The majority also identified the opportunity to provide care and interact with PWDs as the most enjoyable aspect of their experience at the clinic. They reported that the experience helped reduce their concerns about treating PWDs including being more realistic about the time required and ideal quality of the treatment they could provide. These results suggest that their experience in the clinic significantly increased students' comfort in treating PWDs. The respondents expressed a willingness to treat PWDs once graduated and generally identified their experience as being more positive than their expectations.
