Orthodontics rewired: A new approach to predoctoral competency training

OBJECTIVE

To describe changes in a competency-based orthodontics course in response to the COVID-19 pandemic, and compare outcomes before and after these adaptations.

METHODS

Exempted by NYU IRB (#FY2021-4795, #FY2021-5748). At NYU College of Dentistry, assessments and surveys for D3 course groups were compared: 2018 (N = 89, in-person) and 2022 (N = 109, hybrid; remote synchronous with cold-calling). Assessments were identical and proctored. Pass rates, mean scores, and score distributions were compared using t-tests and Z-scores. Internal consistency of surveys was evaluated with Cronbach's alpha. Six paired Likert items were categorized into Positive, Neutral, and Negative and compared using Fisher's exact test and phi coefficients. Four items were added to the 2022 survey to assess students' responses to "cold-calling" and were evaluated using descriptive statistical methods.

RESULTS

No significant differences in pass rates or mean assessment scores were found between 2018 (79.8%, 1.45 ± 1.11) and 2022 (80.7%, 1.50 ± 0.97) groups. Surveys demonstrated high internal consistency (Cronbach's alpha: 0.95 and 0.81). Response rates were 79% and 80% for both groups with a median score of 4 (Agree) or higher, indicating positive confidence and motivation. Fisher's exact test and phi coefficients did not find significant differences across surveys (p ≤ 0.05). The four additional Likert items in the 2022 group survey suggested that cold-calling increased preparedness and anxiety. The median score for cold-call items = 4 (Agree).

CONCLUSIONS

The null hypothesis was upheld. Assessment and survey outcomes for 2018 and 2022 were similar. Students displayed increased confidence and motivation. "Cold-calling" was associated with increased preparedness, engagement, and anxiety.

Satisfaction of orthodontic Post-CCST training: A survey of trainee perceptions

INTRODUCTION

This survey was undertaken as a second part to 'Barriers to Post-CCST training in orthodontics: A survey of trainee perceptions'. Recruitment of Post-CCST trainees in certain areas of the country has attracted concerns as it has become increasingly difficult. This survey was undertaken to assess trainee satisfaction with Post-CCST training and to look at possible ways to improve trainee satisfaction and make Post-CCST training more desirable.

METHODS

The Training Grades Group (TGG) committee of the British Orthodontic Society (BOS) produced an online survey that was sent to all TGG members and newly qualified consultants in May 2021. All Post-CCSTs who entered training between February 2017 and October 2020, were asked to complete the survey.

RESULTS

There were 37 respondents, which gave a response rate of 62%. While 61% of respondents were satisfied with their Post-CCST training, 17% were 'neither satisfied or dissatisfied' and 6% were either 'dissatisfied' or 'very dissatisfied'. Of the 37 respondents, 25 (67%) would apply for Post-CCST training again, 6 (16%) would not and 6 (16%) did not answer this question. When asked for possible suggestions for improvements to Post-CCST training to encourage greater satisfaction, the responses could be grouped into the following themes: Part-time training; Teaching; Time commitment; Salary; and Experience.

CONCLUSION

In general, respondents were satisfied with Post-CCST training. There was a significant range of positive and negative responses to various aspects of training including multidisciplinary team clinic preparation, support, supervision and management experience. Suggestions for improvements echo the barriers to Post-CCST training survey.

Orthodontic clinicians' attitudes and knowledge of dentogingival aesthetics: A cross-sectional survey of BOS members

OBJECTIVE

To assess orthodontic clinicians' knowledge and attitudes towards dentogingival aesthetics and to explore characteristics that predict the knowledge of dentogingival aesthetics.

DESIGN

Cross-sectional questionnaire.

SETTING

On-line survey of members of the British Orthdontic Society.

MATERIALS AND METHODS

An 11-item online questionnaire was sent to orthodontic practitioners for completion. The questionnaire covered respondent demographics and questions relating to both knowledge and attitudes towards dentogingival aesthetics (six parameters). Descriptive statistics were calculated for study characteristics and summary values for the survey items. Responses to the eight knowledge-based questions were converted to a binary outcome (correct and incorrect answer). The maximum score that could be achieved was eight. Multivariable modelling was used in order to examine associations between the study characteristics and the aggregate score.

RESULTS

A total of 252 responses were obtained resulting in a response rate of 17%. Within this cohort, the respondents were primarily women (52.8%) and aged 30-40 years (35.7%). The mean score for the eight knowledge-based questions was 3.8 ± 1.8 (range = 0-8). Knowledge of the ideal gingival margin position of the anterior teeth was high (92.4%). Knowledge of the other five dentogingival aesthetic parameters was variable. In the multivariable analysis, lower knowledge scores were predicated by respondents who did not have a special interest in dental aesthetics (-0.54; 95% confidence interval [CI] = -1.01 to -0.07; P = 0.02), who could not recall attending courses, lectures or seminars on dental aesthetics in the past five years (-0.80; 95% CI = -1.43 to -0.17; P = 0.01) and with increasing age (-0.43; 95% CI = -0.62 to -0.23; P < 0.001).

CONCLUSION

Knowledge of ideal dentogingival parameters is generally suboptimal among orthodontists in the UK. The reported lack of knowledge of the ideal dentogingival parameters may also influence respondents' attitudes towards the importance of dentogingival aesthetics. Further teaching or courses related to dentogingival aesthetics is desired by orthodontic clinicians.

Making competency-based predoctoral orthodontics fun: Introducing Dealodontics

OBJECTIVES

Dealodontics is a card game developed at New York University College of Dentistry for dental students to reinforce and apply basic orthodontic concepts. Dealodontics incorporates clinical photographs and questions to assess students' skills in diagnosis and patient management. The game was designed to be an enjoyable, interactive, and collaborative learning experience, supplementing competency-based instruction. The purpose of this project was to present this novel educational method and to evaluate dental students' engagement and game-playing experience.

METHODS

The survey was modeled after the "Game Experience Questionnaire" and followed the same methodology collapsing 16 survey questions into eight categories. The 5-point Likert scale was collapsed into a 3-point graduated scale (negative, neutral, and positive). Results were tabulated and scored using methods developed by IJsselsteijn et.al. Comparisons were made between two years: 2019 (N = 385) and 2021 (N = 245). Additionally, students were asked an open-ended question, to list three words to describe the game-playing experience.

RESULTS

Response rates declined from 72% in 2019 to 50.2% in 2021. Response trends were similar: Positive gameplay experiences (competence, positive affect, immersion, challenge, and learning) and lack of negative experiences (tension/annoyance, negative affect). In the category of flow, 2021 responses were more positive (42.68%) when compared to the responses in 2019 (38.3%). Open-ended responses were similar with "fun" being the most commonly occurring word.

CONCLUSIONS

Dealodontics is an effective and engaging tool for learning which can be used to supplement traditional methods.

Current status of undergraduate orthodontic education in Canada

PURPOSE

This study evaluated teaching hours and mode of instruction of undergraduate orthodontic education dental students in Canada receive, changes implemented by each educational dental institution (EDI) in response to the COVID-19 pandemic, and plans for mode of orthodontic education delivery post-COVID-19.

METHODS

An electronic survey was administered to the program directors of undergraduate orthodontics at each EDI to reveal details regarding the (i) time and details of didactic, preclinical, and clinical experience provided to students and (ii) perceptions of undergraduate program directors about the adequacy of the current curricula.

RESULTS

All 10 Canadian EDIs participated in the survey during the year 2021. Most EDIs deliver their orthodontic curricula beginning in the second year of the program (7, 70.0%), continuing through third (7, 70.0%) and fourth (6, 60.0%) years. The number of hours of didactic, preclinical, and clinical instruction varied by as much as 50 h per academic year across different EDIs. In response to the COVID-19 pandemic, almost all EDIs (9, 90.0%) maintained the same amount of didactic lecture time yet most switched to synchronous (5, 50.0%) or asynchronous (3, 30.0%) online delivery format. Most EDIs (8, 80.0%) indicated the quality of education was maintained during the pandemic.

CONCLUSIONS

There exists significant variation in undergraduate orthodontic time allotment among Canadian EDIs. During the COVID-19 pandemic, most Canadian EDIs maintained a consistent amount of teaching hours while transitioning to some form of online course delivery. Most program directors indicated they believed students received the same quality of education after the change in mode of course delivery. The future of undergraduate orthodontic education will likely continue the accelerated trend toward online education.

History of Orthodontics in Brazil - Postgraduate Education

Orthodontics in Brazil underwent significant transformations in the 1950s when several dentists returned to the country after completing advanced education courses in the specialty abroad. The first two orthodontic associations, in Rio de Janeiro and São Paulo, were constituted in 1955 and 1959. The specialty's first event with characteristics of a professional meeting occurred in São Paulo in 1957, and Postgraduate Orthodontic education became available. This paper aims to describe the central insights of the constitution and evolving of the education of Orthodontics in Brazil.

Dental students' interest in orthodontic careers: do orthodontic-related experiences and faculty and practitioner role models matter?

OBJECTIVES

To assess the percentage of dental students interested in orthodontics and likely to apply to orthodontic residency programs, the role of orthodontic-related experiences, and of orthodontic faculty and practitioner role models for student career decision-making.

MATERIALS AND METHODS

This study had a cross-sectional design. A total of 335 students from seven U.S. dental schools responded to an anonymous web-based survey.

RESULTS

35% were much/very much interested in becoming orthodontists and 26% were likely to apply for this specialty training. A total of 80.1% had orthodontic treatment, 58.7% knew an orthodontist in their community, 44% had shadowed an orthodontist, and 10.8% had worked in an orthodontic practice before dental school. Respondents evaluated orthodontic practitioners more positively than orthodontic faculty. They considered practitioners as more compassionate providers than faculty members (5-point scale with 5 = agree strongly: mean = 4.25 vs 3.83; P < .001), making more of a difference in their patients' lives (4.44 vs 4.05; P < .001), and as better role models (4.21 vs 3.94; P < .001) who encouraged students more to pursue orthodontics (4.03 vs 3.65; P < .001). Their interest in becoming an orthodontist and in applying for an orthodontic residency program correlated with educational experiences (r = 0.35; P < .001 / r = 0.34; P < .001) and positive impressions of orthodontic faculty (r = 0.23; P < .001 / r = 0.22; P < .001) and practicing orthodontists (r = 0.29; P < .001 / r = 0.27; P < .001).

CONCLUSIONS

Better understanding of factors motivating dental students to pursue orthodontics is crucial. Orthodontic practitioners and faculty play an important role in this context.

3-Dimensional simulations and student learning in orthodontic education

INTRODUCTION

The electronic dental model (e-model) is an example of a digital 3-dimensional technology to support inquiry-based learning in undergraduate dental education. As student perceptions of and engagement with e-models vary, it is uncertain whether these perceptions have implications for their learning processes and outcomes.

MATERIALS AND METHODS

Third-year dental students (N = 40) completed a questionnaire to identify their perceptions of and preferences for model modalities. They were divided into three groups based on their preference: Preferring plaster models (Group 1); Preferring e-models (Group 2); No preference (Group 3). Students from three groups (N = 9) attended a hands-on digital occlusion evaluation workshop, and then completed a case-based diagnostic evaluation test using digital occlusion evaluation software. Camtasia Studio™ recorded real-time and on-screen data of the number of mouse-clicks and time spent.

RESULTS

Students reported positive feedbacks on the use of e-models, and 72.5% of the students preferred combination use of e-models and plaster models. After attending the hands-on digital dental occlusion evaluation workshop, Group 2 scored higher on the diagnostic evaluation test (p < .05) and registered more mouse-clicks than Group 1 when evaluating the arch symmetry (p < .05). Group 2 registered fewer mouse-clicks than Group 3 during tooth size measurement (p < .05). There was no significant difference regarding the time used to answer the knowledge questions amongst the three groups.

CONCLUSION

Undergraduate dental students indicated a generally high acceptance of e-models for their learning in orthodontics, and more prefer a blended approach. Students preferring e-models presented higher performance outcomes, which supports cognitive load theory regarding prior exposure to simulation-based environments.

History of Orthodontics in Brazil - First Brazilian Specialist

At the beginning of the 20^th century science was beginning to transform the world, including Brazil. All aspects of dentistry were considered essential to the welfare of the people and that may also have included orthodontics. It is possible then to assume that the manufacturing of some orthodontic appliances was already being taught in the educational courses. However, the lack of didactic orthodontic texts in Portuguese was a problem, when considering literature as one of the pillars that would support advancements in the science and practice of orthodontics. This difficulty, however, was solved in 1910, when the third edition of the Odontological Manual by Coelho e Souza was published including a chapter on orthodontics. Some years later Carlos Lustosa became interested in this subject after reading the paper by Angle that presented the ribbon arch appliance. He went to Pasadena (CA) and convinced Angle to accept him as a student. In 1923 he completed the course at the Angle School of Orthodontia, becoming the first Brazilian specialist in orthodontics. He treated patients with the ribbon arch until his death in 1937. However, did his search for knowledge outside the country influence the course of Brazilian orthodontics?

Surviving orthodontic graduate debt: Making correct career choices to manage debt re-payment, reduction or forgiveness

Monetary pitfalls and traps await unwary residents upon graduation. The path to a financially satisfying personal and professional life is obtainable despite high student loan debt and limited income. Career and personal finance issues, student loan options, tax avoidance, bank lending policies, and practice purchases are reviewed. Career options of public service, salaried employee, per diem employee, and private practice ownership are compared in personal financial outcomes, taxation, and retirement consequences.

Students' perspectives on the use of digital versus conventional dental impression techniques in orthodontics

BACKGROUND

Despite the increasing use of digital impressions in orthodontics, this technique does not usually form part of the learning objectives in dental training. The aim of this study was to determine how students assess the user-friendliness of intraoral scanners compared to a conventional impression technique after a theoretical and practical teaching module.

METHODS

Thirty-one dental students in their seventh semester (4th year) received and conducted digital (3 M, St. Paul, NM) and conventional (alginate) impressions from: (i) the dentist's perspective, and (ii) the patient's perspective. Each student completed four questionnaires to evaluate: (i) the user-friendliness of intraoral scanning, and (ii) intraoral scanning compared to the conventional method.

RESULTS

Thirty (97%) students had not previously performed digital impressions. Twenty-four (77%) students were overall "very" or "rather" satisfied with the handling of the intraoral scanning method, and 18 (58%) preferred digital to alginate impressions from the dentist's perspective. From the "patient's" perspective, the students did not report any significant differences between the two methods. However, the impression tray in conventional impressions reduced "patient" comfort significantly more than the camera in digital impressions (Z = - 3.496, p < 0.001).

CONCLUSIONS

Dental students were able to practice both conventional alginate and modern digital impressions without prior knowledge of intraoral impression techniques after basic training and an introduction from dentists. Students reported a preference for the digital technique. Implementing digital intraoral impressions into undergraduate training is recommended to familiarise students with this rapidly developing digital technique at an early stage.

Predictors of orthodontic residency performance: An assessment of scholastic and demographic selection parameters

OBJECTIVE

To evaluate the association between resident selection criteria, including Graduate Record Examination (GRE) scores, and student performance in an orthodontic residency program.

MATERIALS AND METHODS

This retrospective study evaluated the academic records of 70 orthodontic residency graduates from the Indiana University School of Dentistry. The following demographic and scholastic data were extracted from the student academic records: applicant age, gender, ethnicity, race, country of origin, dental school graduation year, GRE score, and graduate orthodontic grade point average (GPA). In addition, student American Board of Orthodontics (ABO) written examination quintiles were obtained from the ABO. Scatterplots, analysis of variance, and correlation coefficients were used to analyze the data. Statistical significance was established at .05 for the study.

RESULTS

No associations were found with any component of the GRE, except with the quantitative GRE section, which displayed a weak association with ABO module 2 scores. Dental school GPA demonstrated weak correlations with all ABO modules and moderate correlations with overall and didactic orthodontic GPAs. When assessing demographic factors, significant differences (P < .05) were observed, with the following groups demonstrating higher performance on certain ABO modules: age (younger), race (whites), and country of origin (US citizens).

CONCLUSIONS

Findings suggest the GRE has no association with student performance in an orthodontic residency. However, dental school GPA and/or class rank appear to be the strongest scholastic predictors of residency performance.

Evidence-based dentistry can effectively be taught to dental care professional students - A mixed methods study

BACKGROUND

Little research exists in the teaching of evidence-based dentistry (EBD) to students in the fields of dental hygiene, dental nursing and orthodontic therapy. This study aims to analyse the effect of a 1-day EBD programme on knowledge and confidence whilst also gaining insight into students' experience of the intervention.

METHOD

A mixed methods study was utilised with explanatory sequential design. The population consisted of dental hygiene (DH), dental nursing (DN) and orthodontic therapy (OT) students (N = 44). The intervention consisted of a 1-day active learning EBD programme, delivered via group projects and lectures. In the initial quantitative phase, a standardised questionnaire pre- and post -intervention measured changes in confidence for all participants, whilst change in knowledge was measured for DH and OT students only. Following this, focus groups were scheduled for all members of each discipline 3 months post-intervention for DN and 2 months post-intervention for DH and OT students. Semi-structured focus group schedules were drawn up, and groups organised according to the outcomes of quantitative data analysis. Qualitative results were analysed using a deductive adaptation of Burnard's thematic content analysis.

RESULTS

Forty-two students took part (94.45%) in this study. Median knowledge scores increased from zero to two of five (P < .001), whilst median confidence score doubled from four to eight of eight (P < .001). Results of thematic content analysis were coincident with quantitative results; however, it also provided constructive feedback regarding design and content of the course.

CONCLUSIONS

A 1-day bespoke programme in EBD increased students' confidence and knowledge in EBD skills. However, the findings further suggest that two successive half-day training sessions instead of one full-day training, tied in with coursework that requires the application of the acquired skills, may increase the learning experience further.

Community Orthodontists and Craniofacial Care: Results of a Washington State Survey

Background

Little is known about community orthodontists’ previous training in, experience with, or receptivity to caring for children with craniofacial disorders.

Objectives

(1) To characterize the current level of participation by Washington state orthodontists in craniofacial care; and (2) to identify factors that promote or impede community orthodontists’ involvement in caring for children with craniofacial conditions.

Design

Mail survey.

Methods

A 26-item questionnaire was designed and mailed to all active orthodontists in Washington state (N = 230). Question topics included practice characteristics, training and experience with craniofacial conditions, concerns related to public and private insurance, and communication with craniofacial teams.

Results

Of eligible respondents, 68% completed the survey. Most orthodontists’ patient panels were made up of patients who either have private insurance or pay cash for services. On average, 2% of respondents’ patients were Medicaid beneficiaries. Only 20% of respondents had seen more than three patients with cleft lip and/or palate in the past 3 years. Although a minority of orthodontists receive referrals from (27%) or are affiliated with (11%) craniofacial teams, most orthodontists perceived craniofacial care positively and were interested to learn more about craniofacial care and to accept additional patients with these conditions.

Conclusions

Results of this survey can inform potential strategies to increase access to orthodontic care for children with craniofacial disorders. These would include developing an organized training, referral, and communication system between community orthodontists and state craniofacial teams and considering a case-management approach to facilitate this process.

Six-axis orthodontic force and moment sensing system for dentist technique training

The purpose of this study is to develop a sensing system device that measures three-axis orthodontic forces and three-axis orthodontic moments for dentist training. The developed sensing system is composed of six-axis force sensors, action sticks, sliders, and tooth models. The developed system also simulates various types of tooth row shape patterns in orthodontic operations, and measures a 14 × 6 axis orthodontic force and moment from tooth models simultaneously. The average force and moment error per loaded axis were 2.06 % and 2.00 %, respectively.

[How to manage with rigour but flexibility an orthodontic practice]

INTRODUCTION

An orthodontic office owner must understand the context and then combine logic, emotion, intuition and common sense. The productivity approach is no longer acceptable. It is necessary to combine rigour, flexibility and pragmatism.

DISCUSSION

The obsessive perfectionism is ineffective. In fact, there are four ways to demonstrate a flexible determination: persevere when appropriate, win the support of your entourage, back on some decisions, appeal to the collective will. Another needed feature is to have the flexibility to change its own habits and change the ones of others. Some practical examples based on the five available resources (time, money, people, training and equipment) illustrate the concepts discussed.

CONCLUSION

Both qualities are necessary for the orthodontic business manager today: strong leadership and flexibility. The best attitude lies in the combination of these two seemingly contradictory requirements.

The Effect of Awareness of American Board of Orthodontics Criteria on Treatment Outcomes in a Postgraduate Dental Clinic

The aims of this study were to evaluate the posttreatment outcomes in a postgraduate orthodontic clinic following a course on American Board of Orthodontics Cast and Radiograph Evaluation (ABO-CRE); to compare the outcomes of postgraduate students who took the course before and after finishing treatment of their cases; and to assess if the need for orthodontic treatment as determined by the Index of Orthodontic Treatment Need (IOTN) at the beginning of treatment affected students' final scores. A course on ABO-CRE was given to second- (group A), third- (group B), and fourth- (group C) year postgraduate students at Yeditepe University, Istanbul, Turkey, in 2012. Pre- and posttreatment plaster models of 253 cases (group A) were treated by students in 2011-12. An additional 251 (group B, 2012-13) and 341 (group C, 2013-14) cases were evaluated in the first and second years after the course, respectively. The models were graded retrospectively using the ABO-CRE and IOTN. The results showed that the total mean scores on the posttreatment plaster models were significantly higher in the pre-course group than the first- and second-year post-course group (p<0.05 and p<0.01, respectively). The borderline cases (grade 3) received a lower score on the ABO-CRE than the cases with need (grade 4) (p<0.01) and severe need (grade 5) (p<0.01) for orthodontic treatment. Increasing awareness by giving information about the ABO-CRE significantly improved the posttreatment success of these postgraduate students. After the course, treatment outcomes in the following year were better than two years later, suggesting it may be useful to teach the course annually to refresh students' knowledge.

Postgraduate Orthodontics Students' and Mentors' Perceptions of Portfolios and Discussion as Tools for Development of Reflection

The aim of this study was to analyze the effects of a portfolio learning strategy designed to develop students' reflection abilities in a postgraduate orthodontic program in the UK. Nine first-year postgraduate orthodontic students and seven mentors participated in the one-year program, which included a reflective portfolio, mentorship, and discussion. After the program, the students' and mentors' perceptions were collected using focus groups and individual interviews, respectively. The data were analyzed using thematic analysis. Four categories emerged. The first, reflection, was considered a skill to learn, and time was needed for students to fully understand its meaning and achieve its outcomes. The second theme, characteristics of reflection, was descriptive at the beginning and more critical at the end of the experience. The third theme, outcomes of reflection, involved students' improved problem-solving and action-planning abilities and increased self-awareness, motivation, confidence, and communication skills. In the fourth theme, stimulation of reflection, students did not agree with mentors regarding the importance of reflective writing, but they recognized the value of the portfolio's reflective log in facilitating the reflective process. There was greater agreement between students and mentors regarding discussions with mentors and among peers as tools to achieve higher levels of reflection. Overall, these students and mentors considered the strategy an effective tool for improving students' reflection.

Dental students' experiences of treating orthodontic emergencies - a qualitative assessment of student reflections

INTRODUCTION

Professional regulatory bodies in the UK and Europe state that dental graduates should be able to manage orthodontic emergency patients. Therefore, the aim of this study was to explore dental student experiences of treating orthodontic emergencies within a teaching institution.

MATERIALS AND METHOD

This study was designed as a single-centre evaluation of teaching based in a UK university orthodontic department. The participants were fourth-year dental students who treated orthodontic emergency patients under clinical supervision as part of the undergraduate curriculum. Student logbook entries for one academic year detailing the types of emergencies treated and structured, reflective commentaries for each procedure were analysed using thematic analysis methods. The total numbers and types of orthodontic emergencies treated by students were presented. Overall, self-reported student confidence in managing orthodontic emergencies was calculated. Themes, which represented student reflections, were identified.

RESULTS

Seventy-two students participated in the study. Overall, 69% of students stated they were confident in managing orthodontic emergencies. Students treated a range of emergencies, of which the most frequent was debonded brackets (38%). Reflections from student commentaries were housed under a primary theme of building procedural confidence. Three subthemes were identified: (i) theory-practice integration; (ii) expanding clinical experience; and (iii) importance of a supportive clinical learning environment.

CONCLUSION

The majority of dental students were confident in managing orthodontic emergencies. Theoretical knowledge supplemented by exposure to a range of clinical problems within a supported learning environment made students feel more confident.

Test-Enhanced Learning in Competence-Based Predoctoral Orthodontics: A Four-Year Study

Dental educators intend to promote integration of knowledge, skills, and values toward professional competence. Studies report that retrieval, in the form of testing, results in better learning with retention than traditional studying. The aim of this study was to evaluate test-enhanced experiences on demonstrations of competence in diagnosis and management of malocclusion and skeletal problems. The study participants were all third-year dental students (2011 N=88, 2012 N=74, 2013 N=91, 2014 N=85) at New York University College of Dentistry. The 2013 and 2014 groups received the test-enhanced method emphasizing formative assessments with written and dialogic delayed feedback, while the 2011 and 2012 groups received the traditional approach emphasizing lectures and classroom exercises. The students received six two-hour sessions, spaced one week apart. At the final session, a summative assessment consisting of the same four cases was administered. Students constructed a problem list, treatment objectives, and a treatment plan for each case, scored according to the same criteria. Grades were based on the number of cases without critical errors: A=0 critical errors on four cases, A-=0 critical errors on three cases, B+=0 critical errors on two cases, B=0 critical errors on one case, F=critical errors on four cases. Performance grades were categorized as high quality (B+, A-, A) and low quality (F, B). The results showed that the test-enhanced groups demonstrated statistically significant benefits at 95% confidence intervals compared to the traditional groups when comparing low- and high-quality grades. These performance trends support the continued use of the test-enhanced approach.

Does Reflective Learning with Feedback Improve Dental Students' Self-Perceived Competence in Clinical Preparedness?

The value of dental students' self-assessment is often debated. The aim of this study was to explore whether reflective learning with feedback enabled dental students to more accurately assess their self-perceived levels of preparedness on dental competencies. Over 16 weeks, all third- and fourth-year students at a dental school in the Republic of Korea took part in clinical rotations that incorporated reflective learning and feedback. Following this educational intervention, they were asked to assess their perceptions of their clinical competence. The results showed that the students reported feeling most confident about performing periodontal treatment (mean 7.1 on a ten-point scale) and least confident about providing orthodontic care (mean 5.6). The fourth-year students reported feeling more confident on all the competencies than the third-year students. Their self-perceived competence in periodontal treatment and oral medicine significantly predicted the instructors' clinical evaluations. This study offered insights into determining if structured reflective learning with effective feedback helps to increase dental students' self-perceived level of clinical preparedness.

Assessment of two e-learning methods teaching undergraduate students cephalometry in orthodontics

AIM

Cephalometry is important for orthodontic diagnosis and treatment planning and is part of the core curriculum for training dentists. Training involves identifying anatomical landmarks. The aim of this investigation was to assess whether e-learning improves learning efficiency; a programme specifically designed for this purpose was compared to commercially available software.

METHODS

Thirty undergraduate students underwent traditional training of cephalometry consisting of lectures and tutorials. Tracing skills were tested immediately afterwards (T0). The students were then randomly allocated to three groups: 10 students served as control (CF); they were asked to improve their skills using the material provided so far. Ten students were given a program specifically designed for this study that was based on a power point presentation (PPT). The last group was given a commercially available program that included teaching elements (SW). The groups were tested at the end the six week training (T1). The test consisted of tracing 30 points on two radiographs and a point score improvement was calculated. The students were interviewed after the second test.

RESULTS

Both e-learning groups improved more than the traditional group. Improvement scores were four for CF; 8.6 for PPT and 2.8 for SW. For PPT all participants improved and the student feedback was the best compared to the other groups. For the other groups some candidates worsened.

CONCLUSIONS

Blended learning produced better learning outcomes compared to using a traditional teaching method alone. The easy to use Power Point based custom software produced better results than the commercially available software.

Live demonstration versus procedural video: a comparison of two methods for teaching an orthodontic laboratory procedure

BACKGROUND

To measure the effectiveness of procedural video compared to live demonstration in transferring skills for fabricating orthodontic Adam's Clasp.

MATERIALS AND METHODS

Forty-nine fourth-year undergraduate male dental students were randomly assigned to two groups. The students in group A (n = 26) attended a live demonstration performed by one faculty, while students in group B (n = 23) watched a procedural video. Both the procedural video and live demonstration described identical steps involved in fabricating the Adam's Clasp. Students in both groups were asked to fabricate an Adam's Clasp in addition to completing a questionnaire, to measure their perceptions and satisfaction with the two teaching methods and lab exercise. Blind assessment was performed by one faculty for both groups.

RESULTS

The mean students' scores in the fabrication of the Adam's clasp were 6.69 and 6.78 for the live demonstration (group A) and the procedural video (group B), respectively. No significant difference was detected between the two groups (P = 0.864). Statistically significant difference was found in the mean response between the two groups for statement 6 on the questionnaire, "The steps in the teaching method were presented in a clear fashion and were easy to understand". A higher mean response for group B was found compared to group A (P = 0.049). No significant differences were found between the two groups for the other statements (P > 0.05).

CONCLUSION

Procedural video is equally as effective as a live demonstration. Both methods should be considered in teaching undergraduate orthodontic courses in order to improve the learning experience and to match different learning preferences of students.

Coenraad F. A. Moorrees: Journey to the top of Mons Scolaris (Mount Scholar)

Coenraad F. A. Moorrees was a pioneer in orthodontic education and research. He was the first academic leader to merge clinical and research requirements in a 3-year residency. Beyond his lifelong association with the Harvard School of Dental Medicine and the Forsyth Dental Center (now the Forsyth Institute), his scholarly impact has reached worldwide through his multifaceted publications, but perhaps more potently through his postdoctoral fellows, 52% of whom achieved professorial ranks at academic institutions, and 15% became heads of orthodontic departments. His scholarly productivity cut across various components of facial growth and development, including the critical consideration of the soft tissue profile in evaluating the total face and the assessment of constitutional and psychobiologic panels in diagnosis and treatment of the individual patient. His investigations on dental development yielded cornerstone knowledge that was readily transferred to clinical applications. His contributions in various organizations included extended service for the prestigious National Institute for Dental Research, which oversees the most important research output in the United States. Numerous national and international recognitions were bestowed on him. He combined in his person the attributes of "renaissance educator" and "citizen of the world," reflecting a unique combination of science and humanity.

Introducing Scenario Based Learning interactive to postgraduates in UQ Orthodontic Program

INTRODUCTION

E-learning has gained momentum in health sciences and seems to have great potential in specialist dental education. Higher acceptability by learners is particularly associated with the surge of smart devices. Currently, there are limited number of e-learning modules available for dental education, particularly in Orthodontics.

MATERIAL AND METHODS

Scenario Based Learning interactive (SBLi(®)) software was used for the first time in Orthodontics Postgraduate training at the University of Queensland. Nine interactive modules were created embedded with clinical procedure videos, web-links, evidence-based literature, along with opportunity for self-assessment and evaluation. Qualitative data were collected before and after the administration of the SBLi(®) for Orthodontics. The purpose of this data was to investigate learning styles and the acceptance of e-modules as part of postgraduate training.

RESULTS

Advantages of the package included high acceptance rate, greater confidence in the application of clinical skills covered in the modules and reduced contact time particularly with limited academic staff. E-modules demonstrated high compatibility with the learning styles of the participants and were considered engaging.

CONCLUSIONS

It seems apparent that e-learning is most effective in a blended learning environment, supplemented with the traditional classroom approach, rather than as a sole mechanism for postgraduate training.

Impact of the NBDE grading change on postgraduate admissions processes

The aim of this study was to assess the effect of discontinuing the reporting of National Board Dental Examination (NBDE) Part I numerical scores on postgraduate program directors' admissions selection processes. This cross-sectional survey-based study collected information about two admissions cycles (2012-13 and 2013-14) from directors of American Dental Education Association Postdoctoral Application Support Service (ADEA PASS(SM)) programs in all postdoctoral training disciplines; the response rate was 54.5%. According to the 2012-13 cycle results, these program directors rated an NBDE Part I score the third most important part of an application, behind grade point average (GPA) and class rank (ranked first and second, respectively). In the 2013-14 cycle, in the absence of an NBDE Part I score, almost all other parts of the application increased in importance for the responding directors, but the relative rank of factors remained almost unchanged. Significantly, 71% of the directors reported that it was now more difficult to select interview candidates, and 76% said they wanted some form of national, numerically scored exam. No significant change was noted between the two years in the number of applications or interviews offered per resident position, although the standard deviation of the number of interviews offered increased in both pediatric dentistry and postdoctoral general dentistry.

Implementation of new technologies in U.S. dental school curricula

With dentistry rapidly evolving as new technologies are developed, this study aimed to identify the penetration of emerging dental technologies into the curricula of U.S. dental schools and to explore whether certain school characteristics affected adoption of these technologies. A 19-question survey was sent to the academic deans of all 62 U.S. dental schools. In addition to questions about characteristics of the school, the survey asked respondents to indicate where in their curricula the technology was incorporated: preclinical didactic, preclinical laboratory, clinical didactic, and/or clinical patient experience. Of 62 eligible schools, 33 useable responses were received, for a 52% response rate. The results showed that the greatest overall penetration of dental technologies was in preclinical didactic courses and the lowest was in the preclinical laboratory. Specific technologies implemented in the largest percentage of responding schools were digital radiography and rotary endodontics. The technologies with the lowest penetration were CAD/CAM denture fabrication and hard tissue lasers. These results suggest that the incorporation of technology into dental schools is following that of private practice as the most widely adopted technologies were those with the greatest acceptance and use in private practice. Among the respondents, factors such as class size and age of the school had greater impact on incorporation of technology than funding source and geographic location.

Dentists' requirements for continuing professional development in Ireland. A pilot study conducted at University College Cork

AIMS

To determine the self-assessed continuing professional development (CPD) needs of dental practitioners and identify how each discipline can best be served by a dental CPD programme. To set findings in the context of the available literature and contribute to the development of CPD programmes.

METHOD

Topics were arranged into eight disciplines: practice management; paediatric dentistry; preventive dentistry; orthodontics; behaviour management; dentistry for people with a disability; oral medicine and surgery; and, restorative dentistry. A web-based questionnaire was constructed and administered using a MarkClass 2.21 online survey tool.

RESULTS

Fifty-six self-reported assessment responses were received, with three-quarters of participants having graduated within the past 10 years. Topics in oral medicine and surgery attracted consistently high levels of interest. A tendency to favour topics with a perceived direct clinical application was observed. Topics recommended by the Dental Council as core areas for CPD were given a high level of priority by respondents.

CONCLUSIONS

Traditional lectures remain a valued mode of CPD participation. Practical courses were valued across all dental topics offered. A varied approach to determining the requirements of dentists is essential to appropriately support the practitioner.

Teaching-learning: stereoscopic 3D versus Traditional methods in Mexico City

In the UNAM Faculty of Odontology, we use a stereoscopic 3D teaching method that has grown more common in the last year, which makes it important to know whether students can learn better with this strategy. The objective of the study is to know, if the 4th year students of the bachelor's degree in dentistry learn more effectively with the use of stereoscopic 3D than the traditional method in Orthodontics.

METHODS

first, we selected the course topics, to be used for both methods; the traditional method using projection of slides and for the stereoscopic third dimension, with the use of videos in digital stereo projection (seen through "passive" polarized 3D glasses). The main topic was supernumerary teeth, including and diverted from their guide eruption. Afterwards we performed an exam on students, containing 24 items, validated by expert judgment in Orthodontics teaching. The results of the data were compared between the two educational methods for determined effectiveness using the model before and after measurement with the statistical package SPSS 20 version. The results presented for the 9 groups of undergraduates in dentistry, were collected with a total of 218 students for 3D and traditional methods, we found in a traditional method a mean 4.91, SD 1.4752 in the pretest and X=6.96, SD 1.26622, St Error 0.12318 for the posttest. The 3D method had a mean 5.21, SD 1.996779 St Error 0.193036 for the pretest X= 7.82, SD =0.963963, St Error 0.09319 posttest; the analysis of Variance between groups F= 5.60 Prob > 0.0000 and Bartlett's test for equal variances 21.0640 Prob > chi² = 0.007. These results show that the student's learning in 3D means a significant improvement as compared to the traditional teaching method and having a strong association between the two methods.

CONCLUSION

The findings suggest that the stereoscopic 3D method lead to improved student learning compared to traditional teaching.
