BACKGROUND In Canada, although the incidence of smoking-related oral cavity cancers has decreased, oropharyngeal cancers associated with human papilloma virus (HPV) are on the rise. During their routine interactions with patients, dentists have the opportunity to intervene. This study was conducted to assess dentists' capacity to prevent and detect oral cancers and to identify the barriers and facilitators that affect this capacity. METHODS A 25-item, self-administered questionnaire was emailed to Ontario dentists through their regulatory body. It aimed to assess their perceptions about various aspects of oral cancer prevention and detection, including their knowledge, attitudes and practices. A binary logistic regression model was constructed for each modifiable risk factor (smoking, alcohol use, HPV) to identify the predictors of dentists' readiness to discuss with patients the connection between risk factors and oral cancers. RESULTS Of the 9975 dentists contacted, 932 completed the survey. Most respondent enhanced by improving their training in detecting oral cancers and their readiness to assess and address the risk factors.OBJECTIVES To examine patient demographics, distance traveled and dental-related treatment provided according to type of dental insurance at a large, not-for-profit community dental clinic (CDC) in Vancouver, Canada. METHODS Using electronic dental records, we assessed the use of private and government-sponsored (public) dental insurance at the CDC in 2014 and 2015 at the appointment and procedure levels. https://www.selleckchem.com/products/salinosporamide-a-npi-0052-marizomib.html Study variables included patient demographics, distance traveled, type of treatment provided, type of dental insurance and cost of treatment. RESULTS Examination of records from 9524 appointments involving 16 639 procedures revealed that 44% (4190 appointments) were made by patients with private insurance and 31.4% (2995) by those with public insurance. Patients with private dental insurance were 1.27 times more likely (p less then 0.001) to have restorative treatment than those with public-sponsored dental insurance. Procedures involving tooth extraction were 14.2 times more likely (p less then 0.001) to be performed in patients with public insurance than those with private insurance. CONCLUSIONS Access does not equal equity; although the CDC enables access by various populations, its ability to provide equitable treatment is compromised by external factors. CDCs may have a vital role in oral health equity; however, dental treatment continues to be dictated by financial reimbursement.INTRODUCTION People living in long-term care (LTC) facilities face many oral health challenges, often complicated by their medical conditions, use of medications and limited access to oral health care. OBJECTIVE To determine Manitoba dentists' perspectives on the oral health of LTC residents and to identify the types of barriers and factors that prevent and enable them to provide care to these residents. METHODS Manitoba general dentists were surveyed about their history of providing care and their views on the provision of care to LTC residents. Descriptive statistics, bivariate analysis and logistic regression analysis were carried out. RESULTS Surveys were emailed to 575 dentists, with a response rate of 52.5%. Most respondents were male (62.8%), graduates of the University of Manitoba (85.0%), working in private practice (89.8%) and located in Winnipeg (72.4%). Overall, only 26.2% currently treat LTC residents. A predominant number of respondents identified having a busy private practice (60.0%), lack of an invitation to provide dental care (53.0%) and lack of proper dental equipment (42.6%) as barriers preventing them from seeing LTC residents. Receiving an invitation to provide treatment, professional obligation and past or current family or patients residing in LTC were the most common reasons why dentists began treating LTC residents. CONCLUSION Most responding dentists believe that daily mouth care for LTC residents is not a priority for staff, and only a minority of dentists currently provide care to this population.OBJECTIVE The objective of this study was to assess the shear bond strength (SBS) of orthodontic brackets bonded to uncut enamel with universal self-etch 1-step adhesive systems. METHODS Extracted uncut premolars (n = 160) were randomly divided into 4 groups for treatment with Scotchbond Universal Adhesive (SU), All-Bond Universal (BU), Clearfil Universal Bond (CU) or the control, Adper Scotchbond Multi-Purpose Adhesive. Following bonding of brackets on tooth surfaces, teeth were stored in distilled water for 24 h and 6 months, and brackets were tested for SBS. The adhesive remnant index (ARI) and quantitative percentage of remaining resin (%RR) were recorded. Scanning electron microscopy was used to analyze debonded surfaces qualitatively. SBS and %RR data were analyzed by 2-way ANOVA followed by the Tukey test (α = 0.05). RESULTS At neither time did these universal adhesives achieve satisfactory SBS for orthodontic treatment. The control group had the highest SBS, ARI score and mean %RR (and these differences were significant), while the BU group had the lowest SBS. SBS mean values and ARI scores decreased over time for SU and BU, but remained stable for CU. There was no difference in %RR among the universal adhesives tested. CONCLUSION None of the universal adhesives used in self-etch mode achieved SBS values (at 24 h and 6 months) that were satisfactory for orthodontic treatment.BACKGROUND The spatial arrangement of primary health care (PHC) services is influenced by many factors and varies across provider types. In Canada, unlike physician services, certain PHC services (i.e., dentistry, physiotherapy) are not fully funded under the health care system. As a result, one might expect the arrangement of these services to differ by neighbourhood, even in dense metropolitan areas. OBJECTIVE This study examines the intra-urban variability of geographic access to dental (DS) and physiotherapy (PT) services in relation to family physician (FP) services in an urban area and identifies underserviced neighbourhoods. METHODS Practice location information was gathered from publicly available and routinely updated provincial sources (physician, physiotherapy and dentistry regulatory colleges). A neighbourhood accessibility score for all 3 PHC services was calculated using a GIS-based, 3-step floating catchment area method. A set of parameters, such as catchment type (road network buffer), size (3 km radius) and census centroids (dissemination areas), was used.
