Methods: In March 2009, an e-mail with a link to a 41-item survey was sent to all orthodontic residents in Canada and the United States (n = 944). Results: Of 944 residents contacted, 339 viewed and 208 completed the survey (22.03%). Using a seven-point Likert scale, residents recognized the importance of treating patients with CLP/CFA/SN. When asked if they plan to treat patients with CLP/CFA/SN, 54.48% responded yes, 13.46% no, and 36.06% were unsure. A total of 38.05% said they would charge the same fee as a typical multiarch case, while 58.05% would charge more, and 60% of fourth-year residents would charge twice the fee. Of the respondents, 43.00% were aware of the established fellowship programs in CLP/CFA/SN. Canadian residents (67.9%) were more enthusiastic about completing a fellowship than Americans were. Of the respondents, 29.33% would complete a 1year fellowship, while 70.67% would not. A total of 78.4% of male respondents and 77.4% of American residents indicated they would not pursue a fellowship. Conclusions: Residents supported the importance of treating patients with CLP/CFA/SN, and more than 54% indicated they plan to treat these patients. Residents who indicated that they would not treat these patients sited limited experience and inadequate expertise as the reasons. Less than 30% indicated a willingness to pursue a fellowship program.

An anonymous online questionnaire was sent to all Canadian orthodontic residents in November 2006. Data were assembled and categorized by different variables, and chi-square comparative analyses were performed. Forty-four out of fifty-four residents responded, giving a participation rate of 81.48 percent. Overall, 86.36 percent of responding residents were satisfied with their program. Respondents said they felt they received the appropriate amount of formal didactic teaching sessions and dedicated and protected academic time. All residents indicated their programs offered training in numerous treatment philosophies: 93.18 percent said they have sufficient clinically based training, and 72.73 percent indicated that their research-based training was sufficient. All responding residents indicated they will complete more than thirty patients from start to finish, and 25 percent estimated completion of more than seventy patients by graduation. Residents said they will complete on average five orthognathic surgery, twenty-four extraction, thirty-one non-extraction, eight adult, and thirteen patients in the mixed dentition. Only 50 percent said their programs contained care for disabled or underserved patients. Most (86.36 percent) said they feel they will be adequately prepared to provide unsupervised orthodontic care after graduation. These orthodontic residents indicated they collaborate most with the disciplines of oral surgery, periodontics, and prosthodontics. However, only 52.27 percent indicated they have a formal interdisciplinary program for treating patients. We conclude from the study that Canadian orthodontic residents are satisfied with the didactic, clinical, and research aspects of their programs. They receive comprehensive instruction with the opportunity to complete a significant number of patients, employing a variety of treatment approaches.

Tissue chambers made of sialistic rubber tubing were surgically implanted in the subcutaneous tissue and samples of tissue chamber fluid (TCF) and inflammatory cells were collected by aspiration with a syringe. To evaluate the model for local cytokine production, two cytokine inducers, polyribinosinic-polyribocytidylic acid (poly I:C) and fixed Aujeszky's disease virus infected PK15 cells (ADV-PK15), were injected into the tissue chambers and samples of TCF were collected 0, 4, 8, 12, 24 and 48 h post injection. Poly I:C injections induced local production of interferon-a (IFN-CX) as well as tumor necrosis factor (TNF) in the TCF but kinetic differences in the production of the cytokines were noted. Poly 1:C also induced an increase in cell numbers in the TCF, mainiy due to increased neutrophil numbers. Injections of ADV-PK15 induced local IFN-a production in the TCF as long as the pigs were serologically negative to ADV. Immunofluorescence and in situ hybridization techniques could be applied for characterization of TCF cells. Moreover, cells recovered from the tissue chambers were viable and could be used in functional in vitro tests. Taken together, this tissue chamber model could prove very useful in in

Methods: All program chairs and directors of the 65 US orthodontic residency programs were contacted by e-mail and telephone and asked for permission to e-mail their residents and invite them to take part in an anonymous 57-item questionnaire online. A total of 335 e-mails from 37 programs were obtained, and the survey was sent in May 2007. Basic statistics including chi-square comparative analyses were performed by sex, age, and year of program. Results: A total of 63.04% of orthodontic residents plan to use self-ligating brackets; 84.06% plan to use Invisalign (Align Technology, Santa Clara, Calif); 92.03% plan to use temporary anchorage devices, and 72.26% plan on placing them themselves; 28.26% plan to use cone-beam computerized tomography; 92.75% plan to use a digital imaging program; 45.65% plan to use indirect bonding; and 10.87% plan to use lingual orthodontics. A total of 70.07% plan to use 2-phase treatment, and 61.59% said they will use functional appliances. A total of 81.16% plan to become certified by the American Board of Orthodontics, but only 18.12% thought certification should be mandatory for licensure; 36.50% indicated that a master of science degree should be required in their program, and 77.94% believe that a 24-to 30-month program adequately prepares them for future orthodontic practice. Conclusions: Newer orthodontic technologies such as self-ligating brackets, temporary anchorage devices, and Invisalign as well as functional appliances are expected to grow in popularity in the United States because of projected future use by orthodontic residents. Two-phase orthodontic treatment with functional appliance mechanics will continue to be used. Most orthodontic residents will become certified by the American Board of Orthodontics but do not believe it should be necessary for licensure. Orthodontic residents in the United States believe that a 2-year program adequately prepares them for private practice.

Methods: Program chairs and directors of all 65 orthodontic residency programs in the United States were contacted by e-mail and telephone for permission to e-mail their residents and invite them to take part in on online survey. A total of 335 residents from 37 programs were invited to complete an anonymous 57-item questionnaire in May 2007. Data were categorized, and basic statistics including chi-square comparative analyses were performed. Results: A total of 136 (40.60%) residents completed the survey. A ''passion for orthodontics'' emerged as the most important factor (20.29%) influencing the decision to pursue orthodontics as a career, followed by ''intellectual stimulation or challenge'' (18.12%). Most residents decided to become an orthodontist before they were in dental school (44.93%). Most residents (89.05%) plan to engage in private practice, and only 2 intend to pursue primarily an academic career. The average resident debt was $165,226 at the end of their program. Conclusions: The decision to become an orthodontist is often made early in life, before dental school, and a passion for orthodontics is the motivational factor. Residents plan to enter private practice and not pursue a career in academia. The current shortage of academics and orthodontic researchers will not be resolved from the current pool of orthodontic residents. A possible solution to the academic crisis is to change the selection criteria in programs to accept orthodontic residents who develop a passion for orthodontics while in dental school or to recruit primary researchers and teachers to the specialty. Residents plan to practice in an urban setting. Rural and underserviced areas will probably continue to experience shortages of orthodontists in the future.

Two questionrwires with an academic focus were administered to 67 students. The theoretical model developed contained three perceived control variables, two measures to evaluate academic goals and career commitment, seven measures of academic integration, three measures of social integration, and one measure of academic outcome. Results indicated that students who assumed personal responsibility for their academic performance reported more academic growth and development, that studemts more actively involved in the learning process and more stimulated academically reported higher levels of academic growth, and that favorable interactions with peers positively affected academic growth. Results support the collective importance of ...

Understanding something about the experiences of new faculty should enable postsecondary institutions to be more effective in the recruitment process. The present study examined the adjustment of newly hired faculty at the point of entry into their institutions and subsequently for a three-year period. It was expected that perceived personal control, teaching experience, gender, type of institution, and time would be particularly critical to the adjustment of new faculty. Three surveys were administered one year apart to newly hired, tenure-track faculty who responded to questions about their adjustment experiences. The results indicated that perceived control is a critical factor affecting new hires' emotional well-being, stress levels, job satisfaction, etc., either by itself or ...

Personal interviews were conducted with residents at 533 Winnepeg addresses. Cross-tabulation analysis of interview results against a range of variables found that age, education, income, family member attending the university, and political affiliation were most significant in predicting attitudes toward the University. The results of the survey reflect opinions very similar to results in urban soundings of the Edmonton (Alberta, Canada) area and results of a similar national survey. These various studies have confirmed a high level of support for universities generally, and an appreciation of the role and importance of the institution to social, economic, cultural scientific, and technological development. This is the case generally regardless of whether it is of direct personal benefit to the survey respondent. Responses to some questions revealed a number of areas in which the university could be doing a better job of explaining what it is doing and why. Special concerns of individual groups provided some admonitions which could direct institutions to a renewed scrutiny of particular areas. An appendix lists survey questions. (JB)

However, the potential moderating effects of student and classroom characteristics have not yet been investigated systematically. In two studies, attributional retraining was provided to low-and high-risk students, followed by a videotaped lecture presented by either an ineffective or effective instructor. Attributional retraining enhanced achievement on a lecture-based achievement test only when combined with effective teaching, improving the achievement of students who had previously performed poorly (Experiment l), and of low-achieving externals (Experiment 2). The intervention provided no advantage for previously successful students and low-achieving internals. Moreover, attributional retraining induced a more internal attribution profile in students with an external locus, and increased expectations of future success in both externals and internals, but again only when students also received effective instruction. These results suggest that contextual factors related to the classroom, such as quality of instruction, and individual differences have to be considered when developing attributional retraining programs.

Using Adobe Photoshop 7, a digital image of a posed smile of a sexually ambiguous lower face was prepared so that hard and soft tissue could be manipulated to alter buccal corridor (BC), gingival display (GD), occlusal cant (OC), maxillary midline to face discrepancy (MMFD), and lateral central gingival discrepancy (LCGD). Adult Canadian laypersons (n = 103) completed an interactive computer-based survey of 29 randomized images to compare smile preferences for these variables. The custom survey was developed to display fluid, continuously appearing modifiable smile variables using MATLAB R2008 for presentation. These data were compared with previously published data for US laypersons. Statistical inference was determined using Wilcoxon rank sum tests. Canadian laypersons were more sensitive in detecting deviations from ideal and had a narrower range of acceptability thresholds for BC, GD, OC, MMFD, and LCGD. Ideal esthetic values were significantly different only for BC. It appears that cultural differences do exist related to smile characteristics. Clinically significant differences in the preference of the smile characteristics were found between Canadian and US laypersons. Canadian laypersons, on average, were more discriminating to deviations from ideal and had a narrower range of acceptability.
