Dental antimicrobial stewardship: a qualitative study of perspectives among Canadian dentistry sector leaders and experts in antimicrobial stewardship.

Objectives: Dentistry is a significant contributor to the burden of antimicrobial overprescribing and hence to the global problem of antimicrobial resistance. However, antimicrobial stewardship in Canadian dentistry is nascent, with an acknowledged need for research and coordinated stewardship efforts. This study aimed to gain insights into the perspectives of Canadian dentistry sector leaders and experts on the main drivers of dental antibiotic overprescribing and potential stewardship strategies. Methods: Exploratory qualitative design. Data collection: four one-time, 1 h focus group discussions with 22 experts and stakeholders in antimicrobial stewardship in Canada, recruited through a mix of purposive and snowball sampling. Data analysis: inductive thematic analysis. Results: The analysis yielded five themes: outdated patterns; antimicrobials as a Band-Aid; fear and risk aversion; behavioural change; and why reinvent the wheel? Overprescription in dentistry stems primarily from a perpetuation of outdated prescribing patterns, ubiquitous use of antibiotics as a temporary solution, and an overly cautious antibiotic use by risk-averse providers. Stewardship strategies should be grounded on behavioural change (motivation, robust data and enactment of new behaviours) and may be modelled after tested medical interventions. Conclusions: This study presents a roadmap for behavioural change in dental antibiotic prescribing, and points to the fact that the success of a stewardship actionable plan for Canadian dentistry may depend more on concerted efforts for change than on the creation of novel strategies. Hence, contextualizing and testing medical stewardship programmes in Canadian dentistry may be effective in combatting antibiotic overprescription, thereby contributing to global efforts to reduce antimicrobial resistance.

Socio-demographic predictors of not having private dental insurance coverage: machine-learning algorithms may help identify the disadvantaged.

BACKGROUND: For accessing dental care in Canada, approximately 62% of the population has employment-based insurance, 6% have some publicly funded coverage, and 32% have to pay out-of pocket. Those with no insurance or public coverage find dental care more unaffordable compared to those with private insurance. To support the development of more comprehensive publicly funded dental care programs, it is important to understand the socio-demographic attributes of all those, who find dental care unaffordable. METHODS: This study is a secondary analysis of the data collected from Ontarians during the latest available cycle of the Canadian Community Health Survey (2017-18), a cross-sectional survey that collects information on health status, health care utilization, and health determinants for the Canadian population. First, bivariate analysis was conducted to determine the characteristics of Ontarians who lack dental insurance. Afterwards, we employed machine learning (ML) to analyze data and identify risk indicators for not having private dental insurance. Specifically, we trained several supervised ML models and utilized Shapley additive explanations (SHAP) to determine the relative feature importance for not having private dental insurance from the best ML model [the gradient boosting (GBM)]. RESULTS: Approximately one-third of Ontarians do not have private insurance coverage for dental care. Individuals with an income below $20,000, those unemployed or working part-time, seniors aged above 70, and those unable to afford to have their own housing are more at risk of not having private dental insurance, leading to financial barriers in accessing dental care. CONCLUSION: In the future, government-funded programs can incorporate these identified risk indicators when determining eligible populations for publicly funded dental programs. Understanding these attributes is critical for developing targeted and effective interventions, ensuring equitable access to dental care for Canadians.

Is private insurance enough to address barriers to accessing dental care? Findings from a Canadian population-based study.

BACKGROUND: In Canada, as in many other countries, private dental insurance addresses financial barriers to a great extent thereby facilitating access to dental care. That said, insurance does not guarantee affordability, as there are issues with the quality and level of coverage of insurance plans. As such, individuals facing barriers to dental care experience poorer oral health. Therefore, it is important to examine more keenly the socio-demographic attributes of people with private insurance to particularly identify those, who despite having insurance, face challenges in accessing dental care and experience poorer oral health. METHODS: This study is a secondary data analysis of the most recent available cycle (2017-18) of the Canadian Community Health Survey (CCHS), a national cross-sectional survey. Univariate analysis was conducted to determine the characteristics of Ontarians with private insurance (n = 17,678 representing 6919,814 Ontarians)-bivariate analysis to explore their financial barriers to dental care, and how they perceive their oral health. Additionally, logistic regressions were conducted to identify relationships between covariates and outcome variables. RESULTS: Analysis shows that the majority of those with private insurance do not experience cost barriers to dental care and perceive their oral health as good to excellent. However, specific populations, including those aged 20-39 years, and those earning less than $40,000, despite having private dental insurance, face significantly more cost barriers to access to care compared to their counterparts. Additionally, those with the lowest income (earning less than $20,000 annually) perceived their oral health as "fair to poor" more than those earning more. Adjusted estimates revealed that respondents aged 20-39 were six times more likely to report cost barriers to dental care and ten times more likely to visit the dentist only for emergencies than those aged 12-19. Additionally, those aged 40-59 were two times more likely to report poorer oral health status compared to those aged 12-19. CONCLUSION: Given the upcoming implementation of the Canadian Dental Care Plan, the results of this study can support in identifying vulnerable populations who currently are ineligible for the Plan but can be benefitted from the coverage.

Aerosol-generating procedures and associated control/mitigation measures: Position paper from the Canadian Dental Hygienists Association and the American Dental Hygienists' Association.

Background: Since the outbreak of COVID-19, how to reduce the risk of spreading viruses and other microorganisms while performing aerosolgenerating procedures (AGPs) has become a challenging question within the dental and dental hygiene communities. The purpose of this position paper is to summarize the evidence of the effectiveness of various mitigation methods used to reduce the risk of infection transmission during AGPs in dentistry. Methods: The authors searched 6 databases-MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Library, and Google Scholar-for relevant scientific evidence published between January 2012 and December 2022 to answer 6 research questions about the risk of transmission, methods, devices, and personal protective equipment (PPE) used to reduce contact with microbial pathogens and limit the spread of aerosols. Results: A total of 78 studies fulfilled the eligibility criteria. The literature on the risk of infection transmission including SARS-CoV-2 between dental hygienists and their patients is limited. Although several mouthrinses are effective in reducing bacterial contaminations in aerosols, their effectiveness against SARS-CoV-2 is also limited. The combined use of eyewear, masks, and face shields is effective in preventing contamination of the facial and nasal region while performing AGPs. High-volume evacuation with or without an intraoral suction, low-volume evacuation, saliva ejector, and rubber dam (when appropriate) have shown effectiveness in reducing aerosol transmission beyond the generation site. Finally, the appropriate combination of ventilation and filtration in dental operatories is effective in limiting the spread of aerosols. Discussion and Conclusion: Aerosols produced during clinical procedures can pose a risk of infection transmission between dental hygienists and their patients. The implementation of practices supported by available evidence will ensure greater patient and provider safety in oral health settings. More studies in oral health clinical environments would shape future practices and protocols, ultimately to ensure the delivery of safe clinical care.

Contexte: Depuis l'éclosion de la COVID-19, la façon de réduire le risque de propagation de virus et d'autres microorganismes tout en effectuant des interventions générant des aérosols (IGA) est devenue un enjeu complexe au sein des communautés de la médecine dentaire et de l'hygiène dentaire. L'objectif de cet exposé de position est de résumer les données probantes de l'efficacité des diverses méthodes d'atténuation utilisées pour réduire le risque de transmission des infections pendant les IGA en médecine dentaire. Méthodes: Les auteurs ont effectué des recherches dans MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Library et Google Scholar pour trouver des preuves scientifiques pertinentes publiées entre janvier 2012 et décembre 2022 afin de répondre à 6 questions de recherche sur le risque de transmission, les méthodes, les dispositifs et l'équipement de protection individuelle (EPI) utilisés pour réduire le contact avec les agents pathogènes microbiens et limiter la propagation des aérosols. Résultats: Au total, 78 études ont satisfait aux critères d'admissibilité. La documentation est limitée en ce qui concerne le risque de transmission des infections, y compris le SRAS-CoV-2, entre les hygiénistes dentaires et leurs patients. Bien que plusieurs rince-bouches soient efficaces pour réduire la contamination bactérienne dans les aérosols, leur efficacité contre le SRAS-CoV-2 est limitée. L'utilisation combinée de lunettes, de masques et d'écrans faciaux est efficace pour prévenir la contamination de la région faciale et nasale lors de l'exécution d'IGA. L'évacuation à volume élevé avec ou sans aspiration intraorale, l'évacuation à faible volume, l'aspirateur de salive et la digue dentaire en caoutchouc (le cas échéant) ont démontré une efficacité à réduire la transmission des aérosols au-delà du site de production. Enfin, la combinaison appropriée de ventilation et de filtration dans les salles de traitement dentaire permet de limiter efficacement la propagation des aérosols. Discussion et conclusion: Les aérosols produits lors des interventions cliniques peuvent présenter un risque de transmission des infections entre les hygiénistes dentaires et leurs patients. La mise en oeuvre de pratiques appuyées par les données probantes disponibles assurera une plus grande sécurité des patients et des prestataires dans les milieux de santé buccodentaire. Un plus grand nombre d'études dans les environnements cliniques de santé buccodentaire permettrait de façonner les pratiques et les protocoles futurs dans le but d'assurer la prestation sécuritaire des soins cliniques.

Impact of COVID-19 on hospital visits for non-traumatic dental conditions in Ontario, Canada.

BACKGROUND AND RATIONALE: As general health care is publicly funded in Canada and oral health care is not, many people seek care from hospitals for their dental problems. This study assessed if the unprecedented times of Coronavirus disease (COVID-19) affected the hospital visits for dental emergencies, making disadvantaged populations further vulnerable for attendance of their dental problems. METHODS: Data from IntelliHealth Ontario for emergency department (ED) visits, day surgery visits, and hospitalizations associated with non-traumatic dental conditions (NTDCs) were retrieved for years 2016 to 2020 to assess trends before COVID-19 and changes, if any, for the year 2020. Trends by month, for the years 2019 and 2020, to make straight comparisons and understand the effects of lockdown in Ontario, was also analyzed. RESULTS: In the year 2020, there was a reduction of 40% in day surgeries, 21% in ED visits and 8% in hospitalizations compared to 2019. Stratified by month, largest reductions were observed in April 2020: 96% in day surgeries; 50% in ED visits; and 38% reductions in hospitalizations when compared to the same month of 2019. In May 2020, day surgeries and ED visits though remained reduced, hospitalization rates increased by 31%. CONCLUSION: Hospital EDs are inefficient avenues for handling dental emergencies. Nevertheless, they do remain a care setting that is sought by many for dental problems, and if the need for hospitalization and day surgery is there, this care setting is an important avenue for dentally related medical care. Perhaps unsurprisingly, COVID-19 has lessened the opportunity and capacity for such care. PRACTICAL IMPLICATIONS: Administrators and policy makers can utilize this information to strategize on augmenting community infrastructure for building more effective, and cost-efficient avenues of care for timely management of dental problems.

Detecting dental caries on oral photographs using artificial intelligence: A systematic review.

OBJECTIVES: This systematic review aimed at evaluating the performance of artificial intelligence (AI) models in detecting dental caries on oral photographs. METHODS: Methodological characteristics and performance metrics of clinical studies reporting on deep learning and other machine learning algorithms were assessed. The risk of bias was evaluated using the quality assessment of diagnostic accuracy studies 2 (QUADAS-2) tool. A systematic search was conducted in EMBASE, Medline, and Scopus. RESULTS: Out of 3410 identified records, 19 studies were included with six and seven studies having low risk of biases and applicability concerns for all the domains, respectively. Metrics varied widely and were assessed on multiple levels. F1-scores for classification and detection tasks were 68.3%-94.3% and 42.8%-95.4%, respectively. Irrespective of the task, F1-scores were 68.3%-95.4% for professional cameras, 78.8%-87.6%, for intraoral cameras, and 42.8%-80% for smartphone cameras. Limited studies allowed assessing AI performance for lesions of different severity. CONCLUSION: Automatic detection of dental caries using AI may provide objective verification of clinicians' diagnoses and facilitate patient-clinician communication and teledentistry. Future studies should consider more robust study designs, employ comparable and standardized metrics, and focus on the severity of caries lesions.

Trends in self-reported cost barriers to dental care in Ontario.

BACKGROUND: The affordability of dental care continues to receive attention in Canada. Since most dental care is privately financed, the use of dental care is largely influenced by insurance coverage and the ability to pay-out-of pocket. OBJECTIVES: i) to explore trends in self-reported cost barriers to dental care in Ontario; ii) to assess trends in the socio-demographic characteristics of Ontarians reporting cost barriers to dental care; and iii) to identify the trend in what attributes predicts reporting cost barriers to dental care in Ontario. METHODS: A secondary data analysis of five cycles (2003, 2005, 2009-10, 2013-14 and 2017-18) of the Canadian Community Health Survey (CCHS) was undertaken. The CCHS is a cross-sectional survey that collects information related to health status, health care utilization, and health determinants for the Canadian population. Univariate and bivariate analyses were conducted to determine the characteristics of Ontarians who reported cost barriers to dental care. Poisson regression was used to calculate unadjusted and adjusted prevalence ratios to determine the predictors of reporting a cost barrier to dental care. RESULTS: In 2014, 34% of Ontarians avoided visiting a dental professional in the past three years due to cost, up from 22% in 2003. Having no insurance was the strongest predictor for reporting cost barriers to dental care, followed by being 20-39 years of age and having a lower income. CONCLUSION: Self-reported cost barriers to dental care have generally increased in Ontario but more so for those with no insurance, low income, and aged 20-39 years.

Towards equitable dental care in Canada: Lessons from the inception of Medicare.

Dental care in Canada is primarily financed through private insurance plans and out-of-pocket payments. While Canada is internationally recognized for Medicare, a publicly-funded health insurance system that covers hospital and physician-provided services at the point of care, it remains one of the least equitable Organization for Economic Co-operation and Development countries in terms of affordable access to dental care. Approximately one third of Canadians do not have access to dental insurance, including half of low-income individuals, and individuals with the greatest dental care needs are often unable to reliably access dental services. Select populations-such as children, Indigenous peoples, seniors, and persons living with disabilities-receive some level of publicly-funded dental services, amounting to approximately 6% of total dental spending nationwide. Despite the evolution of Medicare, dental care has been largely excluded from federal health legislation following World War II. However, in March 2022, the Liberal Party of Canada partnered with the federal New Democratic Party to advance common legislative goals, including a long-term nationwide dental program for low- and middle-income families. As an interim measure, Bill C-31 was signed into law on 17 November 2022, and created the Canada Dental Benefit, which provides a fixed transfer payment to individuals with an annual household income under $90,000. This commentary reviews the origins of Canadian Medicare, discusses the factors that led to the continued exclusion of dental care from federal health legislation, examines the newly-minted Canada Dental Benefit, and explores the potential for expanded public funding in Canadian dental care.

A perspective: Challenges and opportunities of a novel national dental benefit.

In Canada, the federal government launched the interim Canada Dental Benefit (CDB) on December 1, 2022, to support access to dental care for children <12 years. The interim benefit shows government's assurance to develop a long-term national dental care program. The benefit will be a cash transfer through Canada's revenue services agency, ranging from $260 to $650 annually. This perspective examines the federal initiative and reflects on its strengths and challenges to learn lessons, which can support the long-term solution that is being currently planned. This article outlines a number of positive aspects as well as challenges from the perspectives of varied stakeholders; the feasibility of the application process; remaining potential gaps due to restricted eligibility criteria; possible effects of unrestricted oral health care services and reimbursement rates; valuing of patient autonomy; guidelines for the expansion of the program to other populations; and remaining barriers to oral health care access are analyzed. The CDB is cause for excitement for the Canadian population because it is an opportunity to reduce affordability barriers to accessing dental care. That said, it is important to discuss anticipated challenges and indirect consequences, particularly through the lens of equity, to support the new CDB and the proposed national dental care program in achieving the much-awaited goal of putting the mouth back into the body.

Dentistry's social contract and dental students' moral inclusiveness.

BACKGROUND: Under dentistry's social contract with the public, dental professionals have a social responsibility to address the oral health needs of the population at large. However, dental education places little emphasis on such moral commitments. By ascertaining dental students' stance regarding these notions, we may be able to inform changes in dental education. This paper thus explores dental students' comprehension of dentistry's social contract using the concepts of moral inclusion, moral community and empathy. METHODS: A cross-sectional online survey collected information from undergraduate dental students at the Faculty of Dentistry, University of Toronto (N = 430). Moral inclusion was assessed through the breadth of students' moral community by computing a "moral inclusion score" (MIS) from Likert scale responses to statements that asked students about their duty of care for different population groups, wherein a higher MIS indicated a broader moral community and in turn greater moral inclusiveness. Empathy was assessed using Likert scale responses to statements that gauged the extent to which students understood the effect of social determinants on people's health. Association of the MIS with environmental, institutional and student-related factors was also investigated using non-parametric tests and linear regression. RESULTS: The survey yielded a response rate of 51.4% (n = 221). Overall, students in this sample were morally inclusive and displayed empathy. Regression results showed that the MIS was most strongly associated with choosing a small town/rural area as a future practice location (ß = 4.76, 95% CI: 0.52, 9.01) and viewing patients as consumers (ß = -3.71, 95%CI: -7.13, -0.29). CONCLUSION: Students in this sample made morally inclusive choices, which implied that they had a basic understanding of the obligations under dentistry's social contract. Improving knowledge and experience with regards to addressing the social and economic determinants of oral health and access to oral health care may positively influence students' perceptions of their professional duties under the social contract.

Teledentistry use during the COVID-19 pandemic: perceptions and practices of Ontario dentists.

BACKGROUND: Teledentistry has demonstrated to expedite oral health consultations, diagnosis, and treatment planning while mitigating COVID-19 transmission risk in dental offices. However, the use of teledentistry by clinicians remains suboptimal. Therefore, this study aimed to determine the perceptions and practices of teledentistry among dentists during the COVID-19 pandemic in Ontario, Canada, and identify associated factors. METHODS: A cross-sectional study using an online 39 item survey was conducted among Ontario dentists in December 2021. The questionnaire inquired about socio-demographic attributes, as well as perceptions of teledentistry use during the pandemic, and its future application. Descriptive statistics including frequency distribution of categorical variables and univariate analysis of continuous variables were conducted. Chi-square test was used determine the associations between professionals' attributes such as age, gender, years of practice, and location of practice, and respondents use of teledentistry. SPSS Version 28.0 was used for statistical analysis. RESULTS: Overall, 456 dentists completed the survey. The majority were general dentists (91%), worked in private practices (94%), were between 55 and 64 years old (33%), and had over 16 years of professional experience (72%). Approximately 49.3% reported using teledentistry; 13% started before the pandemic, and 36% during the pandemic. The most common reason for non-utilization was a lack of interest (54%). Respondents identified patient triage, consultation, and patient education as the three most important uses of teledentistry. Female dentists (p < 0.05), dentist working in private practice (p < 0.05), and those who worked in a single dental office (p < 0.05) adopted teledentistry more during the pandemic. Respondents who accessed more resources were more likely to report greater utilization of teledentistry, while those who reported being unconformable with teledentistry (p < 0.05) reported less utilization. Additionally, participants who reported feeling comfortable discussing teledentistry with others (p < 0.05), were more inclined to use it in the future. CONCLUSIONS: Participants expressed mixed perceptions toward teledentistry with more than half indicating it is reliable for patient triaging and patient follow-ups. Despite the increased utilization during the COVID-19 pandemic, participants' lack of interest in teledentistry emerged as a barrier to its use. More education and knowledge dissemination about teledentistry's areas of application and technical aspects of use can increase interest in this tool, which may lead to a greater uptake by dental professionals.

The Impact of Dental Care Programs on Individuals and Their Families: A Scoping Review.

BACKGROUND: Despite significant global improvements in oral health, inequities persist. Targeted dental care programs are perceived as a viable approach to both improving oral health and to address inequities. However, the impacts of dental care programs on individual and family oral health outcomes remain unclear. OBJECTIVES: The purpose of this scoping review is to map the evidence on impacts of existing dental programs, specifically on individual and family level outcomes. METHODS: We systematically searched four scientific databases, MEDLINE, EMBASE, CINAHL, and Sociological Abstracts for studies published in the English language between December 1999 and November 2021. Search terms were kept broad to capture a range of programs. Four reviewers (AG, VD, AE, and KKP) independently screened the abstracts and reviewed full-text articles and extracted the data. Cohen's kappa inter-rater reliability score was 0.875, indicating excellent agreement between the reviewers. Data were summarized according to the PRISMA statement. RESULTS: The search yielded 65,887 studies, of which 76 were included in the data synthesis. All but one study assessed various individual-level outcomes (n = 75) and only five investigated family outcomes. The most common program interventions are diagnostic and preventive (n = 35, 46%) care, targeted children (n = 42, 55%), and delivered in school-based settings (n = 28, 37%). The majority of studies (n = 43, 57%) reported a significant improvement in one or more of their reported outcomes; the most assessed outcome was change in dental decay (n = 35). CONCLUSIONS: Dental care programs demonstrated effectiveness in addressing individual oral health outcomes. However, evidence to show the impact on family-related outcomes remains limited and requires attention in future research.

The impact of dental care programs on healthcare system and societal outcomes: a scoping review.

BACKGROUND: Dental diseases have detrimental effects on healthcare systems and societies at large. Providing access to dental care can arguably improve health outcomes, reduce healthcare utilization costs, and improve several societal outcomes. OBJECTIVES: Our objective was to review the literature to assess the impacts of dental care programs on healthcare and societal outcomes. Specifically, to identify the nature of such programs, including the type of services delivered, who was targeted, where services were delivered, and how access to dental care was enabled. Also, what kind of societal and healthcare outcomes have been attempted to be addressed through these programs were identified. METHODS: We conducted a scoping review by searching four databases, MEDLINE, EMBASE, CINAHL, and Sociological Abstracts. Relevant articles published in English language from January 2000 to February 2022 were screened by four reviewers to determine eligibility for inclusion. RESULTS: The search resulted in 29,468 original articles, of which 25 were included in the data synthesis. We found minimal evidence that answers our proposed research question. The majority of identified programs have demonstrated effectiveness in reducing medical and dental healthcare utilization (especially for non-preventive services) and avert more invasive treatments, and to a lesser degree, resulting in cost-savings. Moreover, some promising but limited evidence about program impacts on societal outcomes such as reducing homelessness and improving employability was reported. CONCLUSION: Despite the well-known societal and economic consequences of dental problem, there is a paucity of studies that address the impacts of dental care programs from the societal and healthcare system perspectives. MESH TERMS: Delivery of Health Care, Dental Care, Outcome assessment, Patient acceptance of Health Care.

Does Vaping Increase the Risk of COVID-19 Transmission and Make Individuals Who Vape Susceptible to Infection and Prone to Severe Illness? A Review.

The predominant mode of transmission of SARS-CoV-2 virus and coronavirus disease 2019 (COVID-19) is aerosols, and e-cigarettes/vaping products are a source of aerosols. There is a public health concern that the use of these products may increase the risk of COVID-19 transmission, susceptibility to COVID-19 and severity of the disease. Based on a review of existing literature, we found emerging evidence that suggests that people who vape are at higher risk of COVID-19, and, because of compromised lung function, their susceptibility to the disease and the severity of outcomes is increased. Aerosols generated by vaping products could be involved in the transmission of the virus when people are close to others who have been diagnosed with COVID-19 and are vaping. These findings may be useful to health care professionals, including dental professionals, in providing evidence to support informing patients about vaping and how the use of vaping products impacts the risk of COVID-19 transmission, infection susceptibility and severity of illness.

How do dental students perceive the role of dental professionals?

OBJECTIVES: To explore dental students' perceptions of the role of dental professionals as healthcare providers and/or businesspersons. METHODS: A cross-sectional online survey collected information from undergraduate dental students at the Faculty of Dentistry, University of Toronto (N = 430). PPR was assessed through a visual analog scale (VAS) question, with the two ends labeled as "Healthcare Provider" (0) and "Business Person" (100), which asked respondents to point where they perceived dental professionals to be. Association of students' PPR with environmental, institutional and student-related factors was investigated using Chi-square and Spearman's correlation tests and logistic regression. Additionally, information on students' professional attitudes was gathered using: (i) the same VAS question, which asked students what they themselves aspired to be; and (ii) level of agreement with two sets of Likert-type questions highlighting healthcare provider and businessperson attitudes. RESULTS: The survey yielded a response rate of 51.4% (n = 221). The majority of respondents perceived dental professionals as healthcare providers and aspired to be healthcare providers themselves. Results of multivariable logistic regression suggested that perceiving dental professionals as businesspersons was significantly associated with perceiving future patients as consumers. Those who strongly agreed with healthcare provider statements had lesser odds of perceiving dental professionals as businesspersons. CONCLUSION: In this sample of students, perceptions of professionalism appear to be congruent with the normative role of dental professionals as healthcare providers. Dental education should prepare graduates who strongly identify with this role even in the presence of dental care market pressures.

Oral health inequality in Canada, the United States and United Kingdom.

The objective of this study was to quantify the magnitude of absolute and relative oral health inequality in countries with similar socio-political environments, but differing oral health care systems such as Canada, the United States (US), and the United Kingdom (UK), in the first decade of the new millennium. Clinical oral health data were obtained from the Canadian Health Measures Survey 2007-2009, the National Health and Nutrition Examination Survey 2007-2008, and the Adult Dental Health Survey 2009, for Canada, the US and UK, respectively. The slope index of inequality (SII) and relative index of inequality (RII) were used to quantify absolute and relative inequality, respectively. There was significant oral health inequality in all three countries. Among dentate individuals, inequality in untreated decay was highest among Americans (SII:28.2; RII:4.7), followed by Canada (SII:21.0; RII:3.09) and lowest in the UK (SII:15.8; RII:1.75). Inequality for filled teeth was negligible in all three countries. For edentulism, inequality was highest in Canada (SII: 30.3; RII: 13.2), followed by the UK (SII: 10.2; RII: 11.5) and lowest in the US (SII: 10.3; and RII: 9.26). Lower oral health inequality in the UK speaks to the more equitable nature of its oral health care system, while a highly privatized dental care environment in Canada and the US may explain the higher inequality in these countries. However, despite an almost equal utilization of restorative dental care, there remained a higher concentration of unmet needs among the poor in all three countries.

Dental and medical care visits among persons with diabetes in Ontario, Canada, who self-report oral health status.

Periodontal disease is associated with diabetes mellitus and poor overall health. While the biological underpinnings of this relationship have been identified, less is known about the extent to which this relationship is affected by dental and medical care visits. Two studies lead by the primary author (KKP) explored the likelihood of diabetes complications among persons living with diabetes in Ontario, Canada, who were followed prospectively in administrative health data. The results from both studies confirmed that poor to fair self-reported oral health was associated with a greater risk for diabetes complications, and that poor dental and medical care visiting behaviours increased this risk. In general, the findings indicate that a greater number of dental and medical visits had a protective effect on the overall health of persons with diabetes. This discovery has important implications for all health care providers interested in managing oral and systemic health.

La maladie parodontale est associée au diabète sucré et à un mauvais état de santé général. Bien que les causes biologiques de ce lien ont bien été définies, la mesure par laquelle ce lien est influencé par des visites dentaires et médicales est peu connue. Deux études menées par l'auteur principal (KKP) ont exploré la probabilité de complications diabétiques chez les personnes atteintes de diabète en Ontario, au Canada, qui ont été suivies prospectivement dans les données administratives de santé. Les résultats des 2 études ont confirmé qu'un état de santé buccodentaire autodéclaré pauvre à moyen était associé à un risque plus élevé de complications diabétiques, et que de mauvais comportements en matière de visites de soins médicaux et dentaires augmentaient ce risque. Les résultats ont généralement révélé qu'un nombre plus élevé de visites dentaires et médicales ont un effet protecteur sur la santé globale des personnes atteintes de diabète. Cette découverte a d'importantes répercussions pour tous les fournisseurs de soins de santé qui s'intéressent à la gestion de la santé buccodentaire et systémique.

What influences attitudes toward professionalism in dental students?

OBJECTIVES: To explore dental students' attitudes toward professionalism and the environmental, institutional, and student-related factors that may be associated with these attitudes. METHODS: A cross-sectional online survey, conducted in 2020, analyzed data from a convenience sample of undergraduate dental students at the Faculty of Dentistry, University of Toronto. Attitudes toward professionalism were assessed using Likert scale statements related to the American Dental Education Association professionalism values of "Fairness," "Responsibility," "Respect," and "Service-mindedness." Codes ranging from 1 to 5 were assigned for the different levels of agreement and an "attitudes toward professionalism score" (ATPS) was computed by summing the codes for all the statements. Greater agreement with the statements or a higher ATPS indicated more positive attitudes toward professionalism. Association of the ATPS with environmental, institutional, and student-related factors was investigated using non-parametric tests and linear regression. RESULTS: The survey yielded a response rate of 51.4% (n = 221). The majority of respondents agreed with all professionalism statements. Results showed that the ATPS was significantly associated with and decreased for students who viewed their future patients as consumers (ß = -3.41, 95% confidence interval [CI]: -5.21, -1.60), experienced unprofessional faculty behavior (ß = -2.45, 95% CI: -4.88, -0.01), and chose to pursue dentistry for financial benefit (ß = -2.55, 95% CI: -4.63, -0.47). CONCLUSION: This sample of dental students generally had positive attitudes toward professionalism and numerous factors were associated with these attitudes. Enhancing the instruction and reinforcement of professional attitudes may be important to students' application of professionalism in decisions regarding clinical practice.
