Association of Canadian Faculties of Dentistry Educational Framework for the Development of Competency in Dental Programs.

The Association of Canadian Faculties of Dentistry (ACFD) recently developed a proposal that reflects its evolving understanding of competency-based dental education. The ACFD proposal was developed into an Educational Framework for the Development of Competency in Dental Programs and has been adopted by all ten Canadian dental schools as the basis for their ongoing curriculum development and assessment. This framework identifies five global competencies that provide a big picture of the complex skills, knowledge, and behaviors that dental graduates must demonstrate. Detail for clarification and illustration is provided by more comprehensive "components" of each area that elaborate on the global statement and by a new dimension that assists with assessment: "indicators" of the specific knowledge, skills, and behaviors that can be measured as steps towards developing competence. In the information supporting understanding and assessment of the five key areas are both the existing national competency statements to facilitate the use of the framework by other stakeholders and a parallel set of knowledge, skills, and abilities statements developed by the National Dental Examining Board of Canada (NDEB) as the starting point for updating its examination blueprints. This article outlines the development, structure, and contents of the ACFD Educational Framework in the hope that it can serve as the foundation for a new Canadian national competencies document serving all national stakeholders.

Relationship Between Disease Characteristics and Oral Radiologic Findings in Systemic Sclerosis: Results From a Canadian Oral Health Study.

OBJECTIVE: Systemic sclerosis (SSc; scleroderma) is associated with a wide periodontal ligament (PDL) and mandibular erosions. We investigated the clinical correlates of SSc with these radiologic abnormalities. METHODS: Subjects from the Canadian Scleroderma Research Group cohort underwent detailed radiologic examinations. Associations between radiologic abnormalities and clinical manifestations of SSc were examined with univariate and multivariate analyses. RESULTS: The study included 159 subjects; 90.6% were women, the mean ± SD age was 56 ± 10 years, diffuse disease was present in 28.3%, and mean ± SD disease duration was 13.7 ± 8.4 years. Widening of the PDL involving at least 1 tooth was present in 38% of subjects, and 14.5% had at least 1 site in the mandible with an erosion. In analyses adjusting for age, disease duration, sex, smoking, and education, we found significant associations between the number of teeth with widening of the PDL and disease severity assessed by the physician global assessment (PGA) (relative risk [RR] 1.19, 95% confidence interval [95% CI] 1.02-1.39, P = 0.028). Analyses replacing the PGA with the skin score, disease subset, or anti-topoisomerase I antibodies confirmed the relationship with indices of disease severity. There was no relationship between either the number of teeth with periodontal disease or the number of missing teeth, and the number of teeth with wide PDL. A smaller interdental distance (RR 0.89, 95% CI 0.82-0.97, P = 0.006), but not disease severity, facial skin score, or ischemia was associated with a larger number of erosions. CONCLUSION: In SSc, a wide PDL may reflect generalized overproduction of collagen, and mandibular erosions are related to local factors in the oral cavity.

The Canadian Systemic Sclerosis Oral Health Study IV: oral radiographic manifestations in systemic sclerosis compared with the general population.

OBJECTIVE: The aim of this study was to compare oral radiologic abnormalities associated with systemic sclerosis (SSc) against abnormalities in the general population. STUDY DESIGN: Patients with SSc and healthy controls were enrolled in a multi-site cross-sectional study. Included in the radiology examination were a panoramic radiograph, four bitewings, and an anterior mandibular periapical radiograph. Radiographs were evaluated by two oral and maxillofacial radiologists tested for interobserver and intraobserver reliability. Chi-squared tests, Fisher exact tests, and Mann Whitney U tests were used to summarize the radiologic manifestations of patients and controls. RESULTS: We assessed 163 SSc patients and 231 controls. Widening of the periodontal ligament space (PLS) (P < .001), with higher percentage of teeth with PLS widening (P < .001), was significantly more frequent in patients with SSc than in controls. The most significant differences between the two groups were found in the molars and premolars (P < .001). Moreover, 26% of the patients with SSc had a periapical PLS greater than 0.19 mm compared with 13% of the controls (P = .003). Patients with SSc had significantly more erosions compared with controls (14.5% vs. 3.6%; P < .001), mostly in the condyles (P = .022), coronoid processes (P = .005) and other locations (P = .012). CONCLUSION: Patients with SSc had more teeth with PLS widening and erosions of the mandible compared with controls.

Does mandibular edentulous bone height affect prosthetic treatment success?

OBJECTIVES: The aim of this study is to determine whether mandibular bone height affects patients' ratings of satisfaction and function with mandibular 2-implant overdentures (IODs) and conventional dentures (CDs). METHODS: 214 edentulous elders were randomly allocated into 2 groups and treated with maxillary CDs and either mandibular CDs or IODs. Classifications of mandibular bone height were carried out on panoramic radiographs using 4 published methods. At baseline and 6 months after delivery, all participants rated their satisfaction with their prostheses using the McGill Denture Satisfaction Instrument. Independent t-tests and a linear multivariable regression model were used for statistical analyses. RESULTS: Mandibular bone height has no effect on patients' ratings of general satisfaction, nor on ratings of ability to chew, stability, comfort, aesthetics and ability to speak at 6 months (p>0.05, linear regression). There were significant between treatment differences in ratings of general satisfaction, comfort, stability and ability to chew from all mandibular bone height categories, with higher ratings assigned to IODs (p<0.01, t-tests). Linear regression analyses confirmed that, for general satisfaction, as well as ability to chew, stability, comfort, aesthetics and ability to speak, treatment with IODs contributes to higher satisfaction ratings (p<0.001), while mandibular bone height does not. CONCLUSIONS: The evidence demonstrates that mandibular bone height has no effect on patients' satisfaction with the function, chewing ability and comfort of their prostheses. Furthermore, no matter how much mandibular bone, these results suggest that edentulous elders will benefit more from mandibular IODs than from CDs.

Assessing the effectiveness of a new curriculum: Part I.

Although it is important to assess the effectiveness of programs, courses, and teaching methods to ensure that goals are being achieved, it is very difficult to evaluate the impact of fundamental changes in a whole curriculum. This paper reviews measures that have been used in the past in dentistry and medicine for evaluating academic programs: curriculum guidelines; competency documents; discussion and focus groups; competency examinations; board examinations; oral comprehensive examinations; student, alumni, and patient satisfaction surveys; evaluation by instructors; and clinical productivity. We conclude that, since no standard method exists, several tools should be used to obtain a multidimensional assessment.
