Potential of information technology in dental education

Integrating Generative AI in Dental Education: A Scoping Review of Current Practices and Recommendations

BACKGROUND

Generative AI (GenAI) tools like ChatGPT are increasingly relevant in dental education, offering potential enhancements in personalised learning and clinical reasoning. However, specific guidance from dental institutions remains unexplored.

AIM

To identify, analyse and summarise existing guidelines from universities and organisations on using GenAI in dental education, focusing on recommendations for academic staff.

METHODS

A scoping review (10.17605/OSF.IO/3XMP7) searched for GenAI guidance on university websites, search engines (Google Search, Scholar, Perplexity and PubMed) and through contacting relevant academics (January 2022 to June 2024). Two reviewers independently screened and extracted data, including implementation details, AI tools and permitted/prohibited uses. Thematic analysis revealed common applications, benefits, challenges and recommendations.

RESULTS

Thirty-one unique documents were included from 21 universities in 15 countries and three international organisations. Thematic analysis identified common applications, benefits, challenges and recommendations for integrating GenAI, including facilitating teaching and learning, personalised learning, efficient content creation and encouraging critical thinking. However, challenges such as academic integrity, ethical use, bias and privacy issues were also identified. No dental education-specific guidelines were found.

CONCLUSION

This review identified and summarised existing GenAI guidelines from universities and organisations relevant to dental education. The guidelines emphasise ethical use, transparency, academic integrity, secure environments and AI misuse detection tools. However, the absence of dental specific guidance presents an opportunity to fill this gap, providing recommendations for academic staff to integrate GenAI effectively while promoting critical thinking and responsible AI use.

Artificial intelligence chatbots and large language models in dental education: Worldwide survey of educators

INTRODUCTION

Interest is growing in the potential of artificial intelligence (AI) chatbots and large language models like OpenAI's ChatGPT and Google's Gemini, particularly in dental education. To explore dental educators' perceptions of AI chatbots and large language models, specifically their potential benefits and challenges for dental education.

MATERIALS AND METHODS

A global cross-sectional survey was conducted in May-June 2023 using a 31-item online-questionnaire to assess dental educators' perceptions of AI chatbots like ChatGPT and their influence on dental education. Dental educators, representing diverse backgrounds, were asked about their use of AI, its perceived impact, barriers to using chatbots, and the future role of AI in this field.

RESULTS

428 dental educators (survey views = 1516; response rate = 28%) with a median [25/75th percentiles] age of 45 [37, 56] and 16 [8, 25] years of experience participated, with the majority from the Americas (54%), followed by Europe (26%) and Asia (10%). Thirty-one percent of respondents already use AI tools, with 64% recognising their potential in dental education. Perception of AI's potential impact on dental education varied by region, with Africa (4[4-5]), Asia (4[4-5]), and the Americas (4[3-5]) perceiving more potential than Europe (3[3-4]). Educators stated that AI chatbots could enhance knowledge acquisition (74.3%), research (68.5%), and clinical decision-making (63.6%) but expressed concern about AI's potential to reduce human interaction (53.9%). Dental educators' chief concerns centred around the absence of clear guidelines and training for using AI chatbots.

CONCLUSION

A positive yet cautious view towards AI chatbot integration in dental curricula is prevalent, underscoring the need for clear implementation guidelines.

Identifying Needs and Preparing for Curriculum Changes in Indian Dental Education

The aims of dental professional courses are to prepare dental healthcare providers to manage common dental diseases, perform surgeries, and offer prevention. They should also be equipped to understand the needs of the society they are serving and willing to amend their skills. As they are expected to be a part of a team providing health care, they should have the requisite leadership and managerial skills for leading the team to serve its objectives in the best possible way. Thus, with changing times, there is a need to bring reforms in dental curricula. Traditional classroom teaching is now shifting to a competency-based education system across the globe. The Dental Council of India (DCI), as a dental health regulator in the country, implements reforms periodically in an attempt to further strengthen the training process and bring quality improvement in dental education. A process of redesigning the curriculum started a couple of years ago. The technical team supporting this work brainstormed the need for such reforms and studied the existing pattern of undergraduate curricula in other developed countries. It was found that many countries are following outcome-based teaching-learning methods. There are several institutions and professional associations proposing recommendations on curricular reforms, and India also suggests following the same. The new education policy (NEP) of the Government of India (GoI) is also in sync with the changes proposed to the DCI. Though such changes are challenging and require time to strategize and implement, it is essential to have reforms in curriculum, especially related to methods of teaching-learning and assessment, and for this, the dental faculty needs to be trained.

WhatsApp as a Tool in Blended Learning in Dental Education

Background and Objective

Dental education is unique, with clinical/practical learning much different from other professionals. In dentistry, students are exposed much earlier in their curriculum to patients, performing procedures under direct/indirect supervision. Hence, the present review attempted to assess the standing position of dentistry in blended learning worldwide.

Materials and Methods

E-learning modality was at its primitive stage as food for thought among educational task force committees, with only a handful of developed and developing countries equipped with it. During this pandemic, "WhatsApp" became a savior, as it was a widely used educational device among dental teachers and students. Furthermore, it was easily applicable in places where there was difficulty in obtaining regular internet bandwidth, especially in remote/rural areas. It is noteworthy that blended learning/e-learning, when complemented with the conventional teaching method, upskill critical thinking and problem-solving capabilities. Blended learning or virtual reality education should be made feasible without disparity, worldwide. Mind training, both students and staff in hybrid e-learning, is the need of the hour not only to keep pace with digitalized dentistry but to prepare the students to face real-world situations.

Conclusion

The sustainability of dental education should be rethought by dental schools with "Complimented Digital learning" wherever feasible, not only to cope with current trends but also to face unforeseen future challenges.

Knowledge, Attitude, and Perception of Undergraduate Dental Students on Information and Communication Technology and Computer-assisted Learning

Introduction

The use of information and communication technology (ICT) in education and clinical purposes is growing immensely. The usage skill, attitude of dental students, and difficulties faced by students are important concerns to be addressed.

Objective

The study was designed to investigate the knowledge, attitude, and skills of ICT of undergraduate dental students via assessing the ease of computer and internet use among students, the level of computer skills and training of the students, and usage pattern of computer activities.

Materials and methods

A cross-sectional survey was conducted among students of three dental colleges in Haryana using a self-designed questionnaire having sections related to demographics, devices, softwares and search engine usage, ICT skills, ICT attitude, and educational and social use.

Results

The response rate was 81.96%. A total of 99.1% of the individuals responded affirmatively to the usage of mobile phones, 48.4 and 13.1% for laptops and tablets, respectively. The average duration of use of smartphones per day was 4.2121 ± 2.834 hours. Google was opted as the most popular search engine used and PubMed the least popular. Only 12.9% of participants showed a negative attitude toward the use of ICT in studies. More social use than academic use was observed. Attitude scores showed a significant correlation with the educational use of ICT (r = 0.89, p = 0.003).

Conclusion

Most of the participants were well acquainted with the usage and had a positive attitude toward ICT for educational purposes. Sensitization and training in scientific literature search and basics of ICT and their practical utilization in dental education, research, and practice should be included in the curriculum.

When e-learning takes centre stage amid COVID-19: Dental educators' perspectives and their future impacts

INTRODUCTION

The COVID-19 pandemic has necessitated an unprecedented shift from face-to-face teaching to e-learning. Previous surveys revealed the negative impact of COVID-19 on dental education and the physical and psychological well-being of dental students. This qualitative study aimed to investigate the perspectives of dental educators towards e-learning during the pandemic and the impact of this experience on their future adoption of e-learning.

MATERIALS AND METHODS

Semi-structured interviews with dental educators from the National University of Singapore were conducted over Zoom. Audio recordings were transcribed verbatim and subjected to thematic analysis. Data saturation was reached. Consolidated criteria for reporting qualitative research (COREQ) was followed.

RESULTS

Fifteen out of 22 (68%) eligible dental educators were interviewed. Educators had minimal prior e-learning experience. They encountered difficulties in engaging students, assessing students' understanding and adapting their teaching. A practical challenge was to ensure the well-rounded training of competent dentists with adequate patient-interaction skills through e-learning. Self-motivation of the audience, class size, type of teaching and complexity of the material were perceived as factors influencing the suitability of the e-learning format. Educators reported an increased confidence after this emergency e-learning experience. Some considered sustaining or expanding e-learning in their future teaching practice and highlighted the need for continued investment and institutional support, training on the pedagogy of e-learning modalities and curriculum redesign to accommodate blended learning approaches.

CONCLUSIONS

Although the shift to e-learning during the COVID-19 pandemic presented a myriad of challenges, dental educators gained experience and confidence which may accelerate the pace of future e-learning adoption and innovation.

Objective:

To develop and make available, at no cost to the user, Information and Communications Technology (ICT) tools for Dentistry, providing dental information and advice geared toward patients undergoing orthodontic treatment with fixed appliances.

Material and Methods:

A Dentistry-based content that contemplated information and advice concerning orthodontic treatment with fixed appliances was elaborated. The materials, which included instructions on oral hygiene and treatment strategies when faced with possible complications, were evaluated and validated by specialists, whose assessments reached a 85% approval. From the validated content, products using four distinct ICT tools were formulated.

Results:

The following technological products were developed: a program for community radios, three blog posts, four educational and informative videos, and a smartphone application - using texts, as well as images and videos. These ICT tools, geared toward patients wearing fixed orthodontic appliances, were made available by internet at no cost to the user, and the number of accesses is already expressive.

Conclusion:

These technological-scientific tools, developed and provided freely to the population, can aid patients during their treatment with fixed orthodontic appliances, contributing to the dissemination of reliable information, and clarifying doubts that may arise during orthodontic therapy. These free ICT tools serve to facilitate access to scientific knowledge, thereby favoring social inclusion, bearing in mind that this educational and informative material was offered in a simple and accessible manner to the general population.

The effectiveness of a 3D virtual tooth identification test as an assessment tool for a dental anatomy course

INTRODUCTION

There has been a recent demand in dental education for distance learning and the use of virtual assessment tools that can leverage technology to potentially replace physical testing facilities. However, virtual tools that evaluate student learning should be validated prior to adoption. The aim of this study was to investigate the effectiveness, efficiency and user satisfaction of a 3D tooth identification test for a dental anatomy course that can be given remotely.

MATERIALS AND METHODS

First-year dental students (n = 41) enrolled in a dental anatomy course took both traditional in-person practical and virtual 3D tooth identification tests consisting of 25 test items. The test scores, average test durations, faculty time commitment and user perception were collected and analysed. Pearson product-moment correlation coefficients (p < .05) were determined for the criterion measures including real tooth identification test scores, comprehensive written examination and overall grade for the course.

RESULTS

The average number of correct answers for the real and 3D virtual tooth identification examination was 21.3 ± 2.65 and 20.7 ± 2.56, respectively. The average test duration for the real and 3D virtual tooth identification test was 25:00 and 21:16 min, respectively. There was a positive correlation (p < .05) of the 3D virtual tooth identification test with the real tooth identification test (0.368), comprehensive written examination (0.334) and the overall course grade (0.646). The total faculty time commitment for the real and 3D virtual tooth identification test was 96 and 65 min, respectively. The students cited difficulty in manipulating the 3D models.

CONCLUSION

This study presents evidence that the 3D virtual tooth identification test can be used to assess dental students' understanding of dental anatomy effectively and efficiently.

Transferring the sandwich principle to instructional videos: is it worth the effort?

BACKGROUND

The sandwich principle is an educational concept that regularly alternates between collective and individual learning phases within one learning unit. Applying sandwich principle to lectures has proven to be more effective for learning outcomes than classical lectures. Supposedly, this teaching format also leads to a beneficial knowledge transfer when applied to other teaching formats. Therefore, the aim of this study was to investigate the effect of the sandwich principle on instructional videos and how its use was evaluated by students.

METHODS

Participants (n = 51) were randomly allocated into two groups. Both groups were given a test to assess the baseline level of knowledge. Afterwards, the control group watched the normal instructional video on cleft lips and palates, while the sandwich group watched the same video modified according to the sandwich principle. The participants then had to answer 30 single-choice questions to assess their knowledge gain and evaluate the instructional video. Long-term retention of the knowledge was tested again 6 months later using the same test questions. The unpaired t-test and ANOVA were used to compare the results.

RESULTS

Comparison of the pre-test and post-test results of both groups showed significantly increased test scores (p < 0.0001). Regarding long-term retention, the mean test scores were still significantly higher in both groups than before watching the video (p < 0.0001). For all test results, there was no significant difference between the groups (p > 0.05). The evaluation showed that the students highly appreciated the modified video and found the interruptions for repetition of previously learned knowledge useful.

CONCLUSION

The hypothesis that the modification of instructional videos according to the sandwich principle would lead to an improved learning outcome could not be proved subjectively or objectively. Nevertheless, the teaching format was highly appreciated by the students and may have increased their motivation to learn with instructional videos.

Perceptions of dental students towards online education during the COVID-19 pandemic

Purpose

This study evaluated the usage habits, attitudes, and perceptions of undergraduate dental students toward distance (online) learning and identified variables related to those attitudes.

Materials and methods

The study included 1,605 undergraduate dental students who participated voluntarily. The data collection tool consisted of a distance learning attitude scale, a questionnaire on personal information, and open-ended questions. The perceptions of dental students to distance education according to the year and type of dental school they attended were evaluated.

Results

Most students expressed that distance learning in dental courses was not as effective as traditional face-to-face education (59.1%, n=949). While students studying at state universities had a more negative view of distance education, the satisfaction scores of the first-year students were found to be significantly lower than the other students (p<0.05).

Conclusion

Dental students were generally unhappy with the interruption of traditional education caused by COVID-19 and having to continue their education online. However, under the circumstances, they saw it as an advantage allowing them to continue their education and avoid a complete suspension.

Researching COVID-19 tracing app acceptance: incorporating theory from the technological acceptance model

BACKGROUND

The expansion of the coronavirus pandemic and the extraordinary confinement measures imposed by governments have caused an unprecedented intense and rapid contraction of the global economy. In order to revive the economy, people must be able to move safely, which means that governments must be able to quickly detect positive cases and track their potential contacts. Different alternatives have been suggested for carrying out this tracking process, one of which uses a mobile APP which has already been shown to be an effective method in some countries.

OBJECTIVE

Use an extended Technology Acceptance Model (TAM) model to investigate whether citizens would be willing to accept and adopt a mobile application that indicates if they have been in contact with people infected with COVID-19. Research Methodology: A survey method was used and the information from 482 of these questionnaires was analyzed using Partial Least Squares-Structural Equation Modelling.

RESULTS

The results show that the Intention to Use this app would be determined by the Perceived Utility of the app and that any user apprehension about possible loss of privacy would not be a significant handicap. When having to choose between health and privacy, users choose health.

CONCLUSIONS

This study shows that the extended TAM model which was used has a high explanatory power. Users believe that the APP is useful (especially users who studied in higher education), that it is easy to use, and that it is not a cause of concern for privacy. The highest acceptance of the app is found in over 35 years old's, which is the group that is most aware of the possibility of being affected by COVID-19. The information is unbelievably valuable for developers and governments as users would be willing to use the APP.

Preparing dental students for independent practice: a scoping review of methods and trends in undergraduate clinical skills teaching in the UK and Ireland

Introduction The governing bodies for dentistry in the UK and Ireland require dentists, at graduation, to possess the knowledge, skills and attributes which enable them to practise safely, without supervision. The means by which dental schools achieve this may differ and may undergo modification in response to changes in the expectations of governing bodies and challenges within the teaching environment. It is therefore important to identify which of these approaches works well and to disseminate good practice described in the literature.Objectives To use a scoping review to identify from the published literature the methods used to teach clinical dental skills, including innovations, motivations for changes, and factors affecting the delivery and quality of teaching.Method Scoping review methodology was used to select and analyse 57 articles published between 2008 and 2018.Results Innovations in didactic teaching were facilitated by advances in IT and development of virtual learning environments, which promoted independent, self-directed learning. Pre-clinical practical teaching took place in clinical techniques laboratories utilising mannequin heads, with a minority of dental schools using virtual reality simulators in addition. Clinical experience was gained mainly in multi-disciplinary clinics and offsite outreach teaching centres. Insufficient numbers of suitable patients, increasing student numbers and a fall in teaching staff contributed to a reported reduction in clinical experience of certain treatments.Conclusions Contemporary clinical dental skills teaching produces new graduates who possess excellent theoretical knowledge, are prepared and confident in basic clinical skills, but are lacking in experience of complex treatments which may result in a reduced preparedness for independent practice.

Quantitative and qualitative analyses of orthodontic-related videos on YouTube

OBJECTIVES

To investigate content of orthodontic-related videos on YouTube to improve the understanding of orthodontic patients' perceptions and treatment experiences.

MATERIALS AND METHODS

A systematic search was conducted on YouTube on March 20, 2018, and updated on August 4, 2019, to identify all relevant videos using search terms "orthodontic," "orthodontics," "braces," and "orthodontic braces." The data set was captured from YouTube Data API (Application Programming Interface) and stored in an Excel database using a query function written in Python. All videos captured were viewed and categorized by three independent dental investigators using thematic analysis. The top 100 videos (by view count) related to patients' treatment experience were further analyzed using discourse analysis.

RESULTS

A total of 600 orthodontic videos were screened, and 546 were included in the study. Six main themes were identified: (1) individual review of orthodontic treatment (45.8%, n = 250), (2) entertainment (19.8%, n = 108), (3) education (18.3%, n = 100), (4) advertisements (6.6%, n = 36), (5) time lapse of orthodontic treatment (5.3%, n = 29), and (6) do-it-yourself orthodontics (4.2%, n = 23). Of the top 100 videos related to patient's individual review of treatment, patients' main focuses were on pain (24%), problems with chewing and swallowing (12%), and adhesive removal (10%).

CONCLUSIONS

Orthodontic-related YouTube videos are diverse in nature. The most common video category was video providing an individual review of orthodontic treatment experience. Other popular video categories included entertainment, education, and advertisements. A range of do-it-yourself YouTube videos were also identified. YouTube may provide an opportunity for orthodontic professionals to disseminate health information.

Assessing the effectiveness of an online dental pharmacology course

OBJECTIVES

Undergraduate dentistry students in their final year often lack the knowledge and confidence required to prescribe oral health medications. Online courses could help to solve this problem through augmenting traditional teaching methods. This study assessed the effectiveness of a non-curricular, online, clinical case-based dental pharmacology course designed to improve medication management in senior dentistry students.

MATERIALS AND METHODS

This study developed and implemented an online dental pharmacotherapy course for 287 dentistry students in Mexico. Pre- and post-course tests evaluated knowledge acquisition, and a 5-point Likert scale questionnaire was administered to 238 participants to evaluate the course's content and educational strategies.

RESULTS

Mean knowledge scores significantly increased from pre- (5.5 ± 1.6) to post-test (9.1 ± 1.3, P < 0.001). Participants reported a high satisfaction level (70.2%) with the course content and materials, educational techniques, and instructors.

CONCLUSION

These findings support the use of online, clinically based dental pharmacotherapy courses, in conjunction with traditional teaching methods, as a viable strategy for effectively educating dentistry students.

Blended learning of radiology improves medical students' performance, satisfaction, and engagement

Purpose

To evaluate the impact of blended learning using a combination of educational resources (flipped classroom and short videos) on medical students’ (MSs) for radiology learning.

Material and methods

A cohort of 353 MSs from 2015 to 2018 was prospectively evaluated. MSs were assigned to four groups (high, high-intermediate, low-intermediate, and low achievers) based on their results to a 20-MCQs performance evaluation referred to as the pretest. MSs had then free access to a self-paced course totalizing 61 videos based on abdominal imaging over a period of 3 months. Performance was evaluated using the change between posttest (the same 20 MCQs as pretest) and pretest results. Satisfaction was measured using a satisfaction survey with directed and spontaneous feedbacks. Engagement was graded according to audience retention and attendance on a web content management system.

Results

Performance change between pre and posttest was significantly different between the four categories (ANOVA, P = 10⁻⁹): low pretest achievers demonstrated the highest improvement (mean ± SD, + 11.3 ± 22.8 points) while high pretest achievers showed a decrease in their posttest score (mean ± SD, − 3.6 ± 19 points). Directed feedback collected from 73.3% of participants showed a 99% of overall satisfaction. Spontaneous feedback showed that the concept of “pleasure in learning” was the most cited advantage, followed by “flexibility.” Engagement increased over years and the number of views increased of 2.47-fold in 2 years.

Conclusion

Learning formats including new pedagogical concepts as blended learning, and current technologies allow improvement in medical student’s performance, satisfaction, and engagement.

Self-regulated learning strategies in world's first MOOC in implant dentistry

BACKGROUND

Massive Open Online Courses (MOOCs) have been often described as a major innovation Higher Education, but their application in the teaching of clinical disciplines is still very limited, while there is a lack of scientific evaluations in this domain. The aim of this study was to investigate learners' behaviours and correlate patterns of Self-Regulated Learning (SRL) with performance and achievement during a MOOC in Implant Dentistry.

METHODS

The clickstream data of learners from the first run of the MOOC Implant dentistry by The University of Hong Kong were modelled and quantified based on Zimmerman's SRL model. The data were quantitatively analysed by means of k-means clustering for evidence of five SRL behavioural indicators of student activity. The clusters identified were then correlated with student engagement and learning performance.

RESULTS

A total of 7608 individuals enrolled, 5014 engaged (active learners 65.90%), 1277 of them (25.47%) completed the course and 1232 purchased a certificate. Two major groups of learners emerged: Attentive (n = 1433) who were more likely to follow the prescribed pathway in the MOOC and Auditors (n = 3581) who accessed content selectively. There was significantly higher engagement, achievement and completion rates among Attentive than Auditors. Both groups included subcategories (Browser, Digger, Test-driven, Sampler, Persistent) which might reflect different SRL strategies.

CONCLUSION

A MOOC in a clinical discipline can achieve high enrolment and completion rates as compared to current benchmarks. There appears to be a wide diversity of learning behaviours among learners, with two however dominant patterns. Learners with a linear learning pathway achieved significantly higher grades and completion rates than those who accessed content irregularly and selectively. Such differences however might be influenced by the demographic and professional background of the learner, as well as their motivation to attending the MOOC. Certain learning behaviours, in particular how learners access content in relation to assessments might be closer related to SRL.

Mobile learning in dentistry: usage habits, attitudes and perceptions of undergraduate students

Introduction

The aim of this study was to evaluate usage habits, attitudes and perceptions towards mobile learning (m-learning), as well as to identify variables related to those attitudes amongst undergraduate dental students.

Materials and Methods

The study consists of 81 dental undergraduate students who who volunteered to participate. The data collection tool consists of an m-learning attitude scale, a questionnaire, and open-ended questions. To compare the total scores and factors of m-learning attitude scale for demographic information and mobile technology usage habits of the students; the Mann-Whitney U test was used for two independent groups such as gender, presence of electronic devices, and places of Internet usage. The Kruskal-Wallis test was also used to compare the total scores and factors of m-learning attitude scale for more than two independent groups including internet usage purposes and opinions. Spearman's correlation coefficient was performed, and linear regression analysis was used to predict the change in total score according to the purposes of Internet usage.

Results

The majority of students thought that the use of mobile devices in dentistry courses was useful and their attitudes towards m-learning were high. The students generally use the Internet for online shopping, connecting to social networks, and communication. They tend to use mobile technologies for personal use, followed by educational purposes. There were significant differences found in the m-learning attitudes for gender, having a portable power supply and use of mobile devices in dentistry courses. Communication was found significant in predicting the change in total score for the m-learning attitude scale according to the purpose of Internet usage.

Conclusion

Dental students have generally positive attitudes towards m-learning. Students raise awareness towards the promise of m-learning in order to apply their individual technology use and learning behaviours. Designing learning materials and applications for mobile devices may increase students' performances.

Assessing students' confidence in interpreting dental radiographs following a blended learning module

OBJECTIVE

This study assessed senior dental hygiene (DH) students' self-reported confidence in interpreting dental radiographs following the introduction of a blended learning (BL) module for radiology interpretation. The assessment of students was conducted five months prior to graduation.

METHODS

A BL oral radiology module was designed. In order to capture the context, descriptions and differences of students' experience and confidence, a qualitative research approach was selected. Data were captured using a semi-structured interview process and analysed using phenomenographic methods.

RESULTS

Sixteen students were interviewed. Blinded transcripts were analysed, and the main themes relating to confidence were extracted and arranged into categories. The categories were coded as to how confident (low, medium or high) each of the students felt specific to varying contexts and complexities of radiographic interpretation.

CONCLUSION

Predominately, the BL model had a positive impact on DH students' confidence in the interpretation of radiographic findings. However, when asked about their level of overall confidence in interpreting dental radiographs, students still did not describe themselves as confident for all potential findings on radiographs at this point in their education. The students highlighted the importance of having patient history details and clinical assessment findings included in the interpretation exercises and expressed a desire to collaborate with other professionals when interpreting radiographs.

Impact of scientific and technological advances

Advancements in research and technology are transforming our world. The dental profession is changing too, in the light of scientific discoveries that are advancing biological technology-from new biomaterials to unravelling the genetic make-up of the human being. As health professionals, we embrace a model of continuous quality improvement and lifelong learning. Our pedagogical approach to incorporating the plethora of scientific-technological advancements calls for us to shift our paradigm from emphasis on skill acquisition to knowledge application. The 2017 ADEE/ADEA workshop provided a forum to explore and discuss strategies to ensure faculty, students and, ultimately, patients are best positioned to exploit the opportunities that arise from integrating new technological advances and research outcomes. Participants discussed methods of incorporating the impact of new technologies and research findings into the education of our dental students. This report serves as a signpost of the way forward and how to promote incorporation of research and technology advances and lifelong learning into the dental education curriculum.

Evidence-based dentistry for planning restorative treatments: barriers and potential solutions

INTRODUCTION

Evidence-based dentistry (EBD) can help provide the best treatment option for every patient, however, its implementation in restorative dentistry is very limited.

OBJECTIVE

This study aimed at assessing the barriers preventing the implementation of EBD among dental undergraduate and graduate students in Montreal, and explore possible solutions to overcome these barriers.

MATERIALS AND METHODS

A cross-sectional survey was conducted by means of a paper format self-administrated questionnaire distributed among dental students. The survey assessed the barriers and potential solutions for implementation of an evidence-based practice.

RESULTS

Sixty-one students completed the questionnaire. Forty-one percent of respondents found evidence-based literature to be the most reliable source of information for restorative treatment planning, however, only 16% used it. They considered that finding reliable information was difficult and they sometimes encountered conflicting information when consulting different sources. Dental students had positive attitudes towards the need for better access to evidence-based literature to assist learning and decision making in restorative treatment planning and to improve treatment outcomes. Even for dentists trained in EBD, online searching takes too much time, and even though it can provide information of better quality than personal intuition, it might not be enough to identify the best available evidence.

CONCLUSIONS

Even though dental students are aware of the importance of EBD in restorative dentistry they rarely apply the concept, mainly due to time constraints. For this reason, implementation of EBD would probably require faster access to evidence-based knowledge.

Application of the European-modified dental clinical learning environment inventory (DECLEI) in dental schools in Riyadh, Saudi Arabia

AIM

The aim of this study was to evaluate undergraduate dental students' self-perceptions of their clinical dental environment using a valid, concise and more practical version of the Dental Clinical Learning Environment Inventory (DECLEI) questionnaire.

MATERIALS AND METHODS

The 24-item DECLEI was self-administered to fourth- and fifth-year undergraduate dental students from public and private dental schools in Riyadh, Saudi Arabia, during the 2014-2015 academic year. Factor analysis revealed three underlying factors associated with the clinical learning environment. Independent sample t-tests were used to evaluate any associations amongst the items, the factors, the total DECLEI score and other demographic variables. For the scoring system, 6-point Likert scale responses were scored on a 100% scale ranging from excellent to poor.

RESULTS

The mean DECLEI total score was 64.1 (good) of 100. Amongst the factors, the highest mean score, 71.3 (good), was obtained for the patient interactions and professionalism, and the lowest mean score, 50.2 (moderate), was observed for all the negatively worded statements in the DECLEI. The instrument exhibited good discriminant validity as it was able to record significant differences between genders and between public and private institutions in the total DECLEI, the factors and most of the items scored.

CONCLUSIONS

The new DECLEI scale identified several areas of strength and some aspects that could be improved. Overall, the dental students rated the clinical undergraduate programme as more positive than negative.

The development of a learning management system for dental radiology education: A technical report

PURPOSE

This study was conducted to suggest the development of a learning management system for dental radiology education using the Modular Object-Oriented Dynamic Learning Environment (Moodle).

MATERIALS AND METHODS

Moodle is a well-known and verified open-source software-learning management system (OSS-LMS). The Moodle software was installed on a server computer and customized for dental radiology education. The system was implemented for teaching undergraduate students to diagnose dental caries in panoramic images. Questions were chosen that could assess students' diagnosis ability. Students were given several questions corre-sponding to each of 100 panoramic images.

RESULTS

The installation and customization of Moodle was feasible, cost-effective, and time-saving. By having students answer questions repeatedly, it was possible to train them to examine panoramic images sequentially and thoroughly.

CONCLUSION

Based on its educational efficiency and efficacy, the adaptation of an OSS-LMS in dental school may be highly recommended. The system could be extended to continuing education for dentists. Further studies on the objective evaluation of knowledge acquisition and retention are needed.

Pattern of online communication in teaching a blended oral surgery course

AIM

To explore the factors that might affect the patterns of interaction amongst dental students that can be found in asynchronous online discussion fora.

SUBJECTS AND METHODS

It is a qualitative study that involved the participation of 71 dental students (42 male and 29 female) who belong to one academic year. Students were participated in asynchronous online discussion fora as a part of a blended oral surgery course that involved both face-to-face lecture and an online learning environment using the Blackboard learning management system. Qualitative analysis of students' pattern of discussion was performed using Transcript Analysis Tool.

RESULTS

The total number of postings was 410. Sixty-seven of 71 students participated in the discussion by writing posts, whereas all of the students had accessed all of the postings. A positive correlation between imposing vertical questions and the number of non-referential and referential statements was observed. Regarding horizontal questions, a positive correlation was observed with the number of referential statements, whilst there was a negative correlation with the number of non-referential statements.

CONCLUSION

Asynchronous online discussion fora that are integrated as a part of a whole pedagogical practice may provide an opportunity for promoting learning, especially when consideration is given to the structure of problems, timely feedback by tutors and supportive strategies within the discussion threads.

Use of information and communication technology amongst New Zealand dental students

Although international studies have shown an increasing use of information and communication technology (ICT) amongst dental students, there are no published studies specific to New Zealand (NZ). The aim of this research was to identify device ownership and academic utilisation patterns amongst New Zealand dental students, including preferences and perceptions, and barriers to use. All currently enrolled dental students (322) were invited to complete a 15-item questionnaire. Data were statistically analysed in SPSS version 20.0. Qualitative data were analysed using a general inductive technique. The participation rate was 78.6% (N = 253 of 322). The majority of respondents personally owned laptop computers (98%) and smartphones (80.2%). A total of 10.8% of participants used a desktop computer everyday for academic purposes, whilst 78.7% used a laptop computer daily, and 54.7% a smartphone. New Zealand dental students demonstrated a high usage of ICT for their coursework with varied use of different online resources. The most frequently used online resources were search engines, social networking sites and lecture slides provided on Blackboard(®) . A high perceived value was placed on both audio podcasts and video podcasts despite the high value also placed on the traditional lectures. Although most participants (84.5%) felt that their ICT knowledge was adequate to meet academic requirements, a small number (1.6%) did not agree.

Learning histology - dental and medical students' study strategies

PURPOSE

Histology, the science of cells and tissues at the microscopic level, is an integral component of most dental and medical curricula and is often taught using both traditional and novel computer-based didactic approaches. The purpose of this study was to analyse the strategies used by dental and medical students when studying this very visual and challenging subject.

METHODS

Data were collected from 75 dental and 143 medical students, who had almost identical histology learning resources at their disposal.

RESULTS

When compared with their medical counterparts, dental students view histology as a more difficult subject and as less relevant for their future career. Whereas dental students, who are required to attend class unlike medical students, made more use of in-classroom learning opportunities, they did not take as much advantage of out-of-classroom resources. In addition, dental students reported a significantly higher tendency than medical students to work together, rather than to study alone.

DISCUSSION

Small differences in the dental versus the medical learning environment associate with several observed differences in learning strategies that are adopted by dental and medical students.

CONCLUSIONS

These differences should be considered when teaching the subject of histology to dental or to medical students.

Homepages of German dental schools - a target group-oriented evaluation

INTRODUCTION

The Internet represents the central communication medium in higher education. University applicants, students, teachers and scientists use the Internet when seeking information on medicine. The homepages of dental schools are not just sources of information, but also a means of presenting the school. No comparative studies have been undertaken concerning the content and extent of their Internet sites so far.

METHODS

Based on the literature and assessments of medical school websites, 136 criteria were defined within the setting of a Delphi procedure and drawn upon for a standardised evaluation of the websites of all 30 German dental schools. Structure and extent of the content of the websites were evaluated. Possible influencing factors, such as financial resources and number of applicants, were investigated.

RESULTS

The results yielded by the homepages varied considerably. The best Internet site received 84% of the possible points, the poorest 38%. On average, 62% of the criteria were fulfilled. Influencing factors, such as the amount of funding by the particular state government, could not be detected. Two-thirds of the dental schools addressed students, three-fourth teachers and scientists as target groups. More than 50% did not address applicants. Specific requirements regarding barrier-free accessibility of information were hardly met.

CONCLUSIONS

Individual faculties already have homepages of a high quality; for others, there is a need for improvement. General recommendations for university websites should be discussed at the European level to ensure a uniform standard of quality. The criteria presented here offer faculties the possibility to reflect upon their own Internet sites.

Attitudes towards e-learning amongst dental students at the universities in Croatia

AIM

To develop and test the psychometric characteristics of a questionnaire that measures attitudes towards e-learning, as well as to study attitudes about e-learning and to identify variables related to those attitudes amongst dental students.

SUBJECT AND METHODS

The study was conducted from November 2010 to December 2011 at all three Croatian dental schools. A questionnaire entitled 'Attitude Towards e-Learning' consisting of 12 questions about socio-demographic data and 22 statements about attitude towards e-learning was self-administered by 386 students. Factorial analysis and Cronbach's alpha were used to test the psychometric characteristics of the questionnaire. Multiple regression analysis was used to identify variables related to attitudes towards e-learning.

RESULTS

Factorial analysis confirmed two factors: positive attitude and negative attitude, which interpret 58% of the total variance and had good internal consistency of α = 0.852 and 0.668, respectively. The average score of positive attitude was 42 ± 6, indicating a highly positive attitude towards e-learning. The average score of negative attitude was 27 ± 6, indicating minor negative attitude. Higher age and study year, usage of the Internet in education, more frequent usage of Facebook and more attendance of e-courses demonstrated a significant influence on positive attitude towards e-learning (R(2)  = 0.304; P < 0.001). Lower year of study and less frequent attendance of e-courses had a significant influence on negative attitude (R(2)  = 0.268; P < 0.001).

CONCLUSIONS

Dental students have generally positive attitudes towards e-learning. Teachers should adopt strategies to change negative attitudes by introducing more e-learning courses in lower study years and should encourage students to use the Internet in their education and communication with teachers and colleagues.

Acceptance of e-learning devices by dental students

Background

E-Learning programs and their corresponding devices are increasingly employed to educate dental students during their clinical training.

Objective

Recent progress made in the development of e-learning software as well as in hardware (computers, tablet PCs, smartphones) caused us to more closely investigate into the habits of dental students in dealing with these learning techniques.

Methods

Dental students during their clinical training attended a survey compiled in cooperation with biostatisticians. The questionnaire probands were asked to complete based on previous surveys of similar subjects, allowing single as well as multiple answers. The data, which were obtained with respect to the learning devices students commonly employ, were compared with their internet learning activities.

Results

The e-learning devices utilized are of heterogeneous brands. Each student has access to at least one hardware type suitable for e-learning. All students held mobile devices, about 90 percent employed laptops, and about 60 percent possess smartphones. Unexceptional all participants of the survey acknowledged an unlimited internet access. In contrast, only 16 percent of students utilized tablet PCs. A detailed analysis of the survey outcome reveals that an increasing use of mobile devices (tablet PC, smartphone) facilitates internet learning activities while at the same time utilization of computers (desktop, laptop) declines.

Conclusions

Dental students overwhelmingly accept e-learning during their clinical training. Students report outstanding preconditions to conduct e-learning as both their access to hardware and to the internet is excellent. Less satisfying is the outcome of our survey regarding the utilization of e-learning programs. Depending of the hardware employed only one-third to barely one-half of students comprise learning programs.

Teledentistry: a systematic review of the literature

We conducted a systematic review of teledentistry applications. We searched the MEDLINE/PubMed, Embase and Cochrane Library databases for relevant articles published from 1992 to 2012. The reference lists of all retrieved articles were hand-searched. Studies were included after assessing the eligibility of the full-text article. A total of 878 studies were identified, of which 59 fulfilled the inclusion criteria of the review. The articles covered several dental specialties, mostly oral surgery, oral medicine and oral pathology. The most common type of teledentistry application was education (n = 21), followed by diagnosis (n = 16), consultation (n = 3) and treatment (n = 2). Teledentistry studies were reported in a total of 15 countries. The largest number of studies were conducted in the US (n = 22) and there were no studies from developing countries. Most of the reports referred to pilot projects and short-term outcomes, and most of the studies were descriptive. The review indicates that although teledentistry is an area of expansion, there are still some barriers to its increased use.

Guidelines for the organisation of continuing professional development activities for the European dentist

AIM

Free movement of dental professionals across the European Union calls for more uniform continuing education in dentistry to ensure up-to-date, high-quality patient care and patient safety. This article provides guidelines for the management and delivery of high-quality continuing professional development (CPD) by European dental schools and other CPD providers.

METHOD

The guidelines are based on an extensive literature inventory, a survey of existing practices (both available as separate publications), discussions during meetings of the Association for Dental Education in Europe in 2011 and 2012 and debate amongst the members of the DentCPD project team representing six dental schools.

RESULTS

On the basis of the literature review, survey and discussions, we recommend that (i) every dentist should be given the opportunity for CPD, (ii) providers should be quality-approved and impartial, (iii) educators should be approved, impartial, suitably trained, and with educational expertise, (iv) the mode of CPD delivery should suit the educational activity, with clear learning objectives or outcomes, (v) effort should be made to assess the learning, (vi) participant feedback should be collected and analysed to inform future developments and (vii) uniform use of the pan-European system of learning credit points (ECTS) should be implemented.

CONCLUSION

Implementation of these guidelines should make dental CPD more transparent to all relevant parties and facilitate the transferability of earned credits across the European Union. It will also enable better quality control within dentistry, resulting in enhanced dental care and ultimately the improvement in patient safety.

Recommendations for the development of e-modules for the continuing professional development of European dentists

AIMS

To provide evidence-based and peer-reviewed recommendations for the development of dental continuing professional development (CPD) learning e-modules.

METHODS

The present recommendations are consensus recommendations of the DentCPD project team and were informed by a literature research, consultations from e-learning and IT expert, discussions amongst the participants attending a special interest group during the 2012 ADEE meeting, and feedback from the evaluation procedures of the exemplar e-module (as described in a companion paper within this Supplement). The main focus of these recommendations is on the courses and modules organised and offered by dental schools.

RESULTS AND DISCUSSION

E-modules for dental CPD, as well as for other health professionals' continuing education, have been implemented and evaluated for a number of years. Research shows that the development of e-modules is a team process, undertaken by academics, subject experts, pedagogists, IT and web designers, learning technologists and librarians. The e-module must have clear learning objectives (outcomes), addressing the learners' individual needs, and must be visually attractive, relevant, interactive, promoting critical thinking and providing feedback. The text, graphics and animations must support the objectives and enable the learning process by creating an attractive, easy to navigate and interactive electronic environment. Technology is usually a concern for learners and tutors; therefore, it must be kept simple and interoperable within different systems and software. The pedagogical and technological proficiency of educators is of paramount importance, yet remains a challenge in many instances.

CONCLUSIONS

The development of e-courses and modules for dental CPD is an endeavour undertaken by a group of professionals. It must be underpinned by sound pedagogical and e-learning principles and must incorporate elements for effective visual learning and visual design and a simple, consistent technology.

The development of an exemplar e-module for the continuing professional development of European dentists

AIM

To present the development of an exemplar e-module for dental continuing professional development (CPD) provided by dental schools and other dental educational providers.

MATERIALS AND METHODS

The exemplar e-module covered the topic of 'Sterilisation and cross-infection control in the dental practice' as this is one of the most recommended topics for dental CPD in Europe. It was developed by a group of topic experts, adult learning and distance learning experts and a technical developer. Major concerns were pedagogy, interoperability, usability and cost reduction. Open-source material was used to reduce the cost of development.

RESULTS

The e-module was pre-piloted in dental practitioners for usability and then evaluated by experts in the field and dental academics through an electronic questionnaire and an online presentation and discussion at the ADEE 2012 Special Interest Group on DentCPD-Lifelong learning. This facilitated refinement before final production. A Creative Commons License was implemented to ensure the developers' rights and facilitate wider distribution and access to CPD providers.

DISCUSSION AND CONCLUSIONS

The e-module was developed according to well-defined pedagogical and technical guidelines for developing e-learning material for adult learners. It was structured to promote self-study by directing learners through their study, promoting interaction with the material, offering explanation and providing feedback. Content validity was ensured by extensive review by experts. The next step would be to expand the evaluation to practising dentists in various countries after relevant translations, and adaptations to local policies have been made.

Connecting with different audiences: the anatomy of communication is essential

In the twenty-first century, communication has become truly global. Advances in technology have opened up a host of ways in which we are able to communicate to retrieve or pass on information and knowledge. In many cases we have moved from a place-based communication approach to one of increasing mobility. With this shift in approach, it is apparent that effective communication skills are perhaps even more important so that we can connect appropriately with diverse audiences. Despite this, relatively little attention has been paid to training our students in different modes of communication and therefore we may not be fully preparing our students to play their part in the global community. Given anatomy's place within many health-care curricula, an ideal avenue is available for anatomists to take the lead in providing communications skills training for students. There are a variety of approaches, some of which are outlined in this article, which can be used to create appropriate opportunities for developing different communication skills and these can be woven into existing practices to ensure courses do not become overburdened. A sustained approach to communication skills training will help equip our students to communicate easily with the many aspects of modern society.

Evaluation of a web-based application versus conventional instruction in the undergraduate curriculum of fixed prosthodontics

AIMS

The present study aims to investigate the implications of web-based delivery of identical learning content for time efficiency and students' performance, as compared to conventional textbook resources.

MATERIALS AND METHODS

Two cohorts of third year undergraduate dental students in 2003 (n = 35) and 2006 (n = 32) completed the study. Following a baseline pre-test, the students were divided into two groups and given 3 weeks for studying identical content using a web-based application (group A) or a conventional paper manuscript (group B). Post-test, end of semester examination and a final retention test were taken. Test scores and studying time was registered for both cohorts in 2003 and 2006.

RESULTS

Group A and B knowledge gain was highly significant between the average per cent scores from pre-test, post-test and end of semester examination in both cohorts in 2003 and 2006 (P < 0.005). Group A spent 1.6× (2003) to 2.6× (2006) less time studying than group B. The average total studying time recorded for group B was 5.1 h using 6.2 learning sessions in 2003 and 3.5 h using 4.4 sessions in 2006. With group A, significantly less time was measured for studying through web-based content using an average of 2.5 h over 4.4 learning sessions in 2003 and 1.5 h added over three sessions in 2006.

CONCLUSIONS

Web-based delivery of identical content results in less overall studying time as compared to textbook delivery. These results appear independent of the students' own preference of the learning medium.

Can easy-to-use software deliver effective e-learning in dental education? A randomised controlled study

INTRODUCTION

For the production of computer-based learning environments, a wide range of software solutions can be used which differ not only in their functionality but also vary in cost and ease to program. The aim of our study was to evaluate the overall efficiency and student's perception of two case-based e-learning programs that were produced with either an easy-to-use or a complex software.

MATERIALS AND METHODS

Eighty-five dental students were randomly assigned to one of two experimental groups. One group studied with a laborious, high-interactive e-learning program (complex-software group). The second group studied within a low-interactive learning environment (easy-software group) that was easy to be programmed. Both programs identically referred to a case report on localised aggressive periodontitis. Learning outcome was tested by a pre- and post-test. Furthermore, questionnaires on workload, motivation, perceived usefulness and perceived learning outcome were used.

RESULTS

Learners in the easy-software group showed better results in the post-test F(1, 82) = 4.173, P < 0.044).

DISCUSSION

Even easy-to-use software tools have the potential to be beneficial in dental education. Students were showing a high acceptance and ability in using both e-learning environments.

CONCLUSIONS

We conclude that e-learning programs for case-based learning do not have to be overly laborious to program to be useful. Based on our results, we want to encourage instructors to produce case-based e-learning tools with easy-to-use software.

Understanding public health informatics competencies for mid-tier public health practitioners: a web-based survey

The literature suggests that there is a need for measuring public health informatics (PHI) competency to further understand whether current educational modules and modalities meet the needs of PHI practitioners and researchers to perform their jobs more effectively, particularly for mid-tier practitioners that constitute the majority of public health workers in the USA. The present study seeks to update current knowledge of the perceptions and experiences of PHI competencies proposed by the U.S. Council on Linkage in Public Health specifically for mid-tier PH practitioners and researchers. The results were collected and analyzed by using a Web-based survey (WBS) method administered among both practitioners and researchers. Researchers first compiled a draft list of candidate competency set by incorporating existing competency areas provided by: 1) the Council on Linkage; and by 2) those proposed by the USA's Centers for Disease Control CDC Public Health Informatics Work Group. Nine sets of competency statements with 120 competency items and demographic information of respondents were included in the WBS. The online survey instruments were pilot-tested accordingly to incorporate feedback from respondents of the pilot. Fifty-six subjects were recruited from PH experts who were: 1) members of the Health Informatics Information Technology (HIIT) group of American Public Health Association; and, 2) members from the Community of Science (COS) Website who were the first authors published in the PHI field from PubMed. The sample included diverse backgrounds of PHI workers. They expressed an increased need for training to improve their PHI competencies. Respondents agreed that four competency sets should be adequately represented, including Leadership and System Thinking Skills (82%), followed by Financial Planning and Management Skills (79%), Community Dimensions of Practice Skills (77%), and Policy Development/Program Planning Skills (63%). The findings parallel current literature indicating that there exists an expressed need for clarification of the public health practitioner's job-specific informatics competency. Findings of expressed needs for basic computer literacy training and community-based practice were consistent with those of the literature. Additional training and resources should be allocated to address the competency of leadership, management, community-based practice and policy advocacy skills for mid-tier public health practitioners to perform their jobs more effectively. Only when healthcare organizations properly identify PHI competency needs will public health practitioners likely improve their overall informatics skills while improving diversification for contribution across multiple settings.

Restructuring an undergraduate dental curriculum to global standards--a case study in an Indian dental school

Globalisation has affected all aspects of life and dentistry is no exception. In the context of today's dentist being a global citizen, undergraduate training in dentistry is set to ensure converging standards so that international recognition of dental qualifications can move forward. The decision of the Dental Council of India to expand the undergraduate dental program to five years provides an opportunity to be part of the endeavor of the Global Dental Congress to achieve converging standards which was initially for the European Union, and now spreading out globally. Economic emergence in Indian subcontinent has resulted in growing oral health care needs both in quality and quantity. To address this issue, the graduating dentist needs to be trained following a competency based curricular model. Access to Internet facilitated the goal of achieving converging standards of dental schools to be feasible because of the instant communication and capacity to share information about training strategies via technology across the globe. Upgrading the undergraduate training to global standards by dental schools in India could be a wise and strategic move both for attracting students to study in India, as well as retaining the graduates after their training. The following is a case study of an Indian dental school set to restructure the undergraduate curriculum to global standards using the 8 steps of Kotter's transformational change. Change in curriculum and the subsequent accreditation of the school in global platform not only attracts prospective students but also results in producing competent dentists. Dental education provided by the institution can result in quality assurance, benchmarking the assessment system to achieve international recognition. This paper highlights the need and importance of facilitation of international convergence with long term aspirations for mutual recognition of international degrees.

The use of video-clips as a teaching aide

INTRODUCTION

Video-clips of tooth preparations recorded with a digital head-mounted camera replaced live demonstrations midway in a preclinical operative dentistry course. DVDs of the video-clips were made available to the students for home use.

AIMS

The aim of this study was to determine whether the use of these video-clips had any impact on students' practical examination results and to analyse students' opinions of this new technology and the perceived impact on their learning.

METHODS

A questionnaire was administered to all students (n = 26) who completed the course, asking their opinions on the video-clips. The results of student practical examinations before the introduction of the camera were compared with those after the video-clips were available and also to the examination outcomes of the previous year's students (ANOVA, P < 0.05).

RESULTS

Twenty-one students completed the questionnaire. Sixteen students (76%) preferred the video-clips to the live demonstrations, and 12 students (57%) made and reviewed the DVDs at home. They expressed a preference for the videos to be made available online or as podcasts. Twelve students (57%) felt that one-to-one supervision was more effective developing their competence in tooth preparations when compared to their viewing of the video-clips. There were no statistically significant differences between the practical examination results.

CONCLUSION

In this group of students, video-clips were the preferred method of demonstration of tooth preparations in the preclinical environment. However, students perceived their learning to be facilitated more by one-to-one supervision. The students preferred to have the video-clips made available to them online instead of in the form of a DVD. The introduction of this educational aide did not make a difference in practical examination results.

Evaluation of a blended learning course for teaching oral radiology to undergraduate dental students

AIMS

The purpose of this study was to develop and implement a blended course (a combined face-to-face and online instruction) on undergraduate oral radiology and evaluate it by comparing its educational effectiveness (derived from students' performance and answers to questionnaires) to a conventional course's. Students' attitudes concerning the blended methodology were also registered.

METHODOLOGY

An original course was developed and implemented, and its electronic version was uploaded to an e-learning educational platform. The course was attended by two groups of final-year students, who were taught by either the conventional face-to-face methodology or the blended learning methodology. Students answered a series of questionnaires, before and after following the course, regarding their perceptions, attitudes and evaluation of the course. Additionally, they completed knowledge assessment tests and their grades (before and after the course) were compared. Educational effectiveness of the course was determined by analysing the results of the questionnaires and the tests.

RESULTS

Students in the blended group performed significantly better than their colleagues of the conventional group in the post-course knowledge test, and female students of the blended group performed better than male students. Students evaluated high the course content, organisation, educational material, and the blended group students additionally appreciated the course design and clarity of instructions. Students' attitudes towards elements of blended learning (effectiveness, motivation and active engagement) were very positive. Most of the blended group students, who attended the face-to-face meeting (approx. 91%), evaluated it as helpful for summarising the subject and clarifying difficult issues.

CONCLUSIONS

Blended learning is effective and well evaluated by dental students and can be implemented in undergraduate curriculum for teaching oral radiology.

Development and status of e-Learning program at Tokyo Dental College

This article reports the development and current status of an e-Learning system (hereafter, referred to as "ELS") at Tokyo Dental College. The ELS was developed to promote self-study. In order to achieve this, all new students were encouraged to use a notebook PC, and an intramural IT environment providing full, wireless LAN Web access was established. One key aspect of the ELS is the inclusion of a series of organically integrated lectures. This system represents a new departure in the development of fully technology-integrated dental education, providing a program which allows the student to select "unified themes" which incorporate those tackled in the standard curriculum as "systematic subjects". Integrated learning is further enhanced, as the system contains "topic spaces" which allow access to all related topics and information throughout the entire system in order to support cross-sectional learning by each student. The system was developed based on the following 2 criteria: 1) there must be relevance to the standard syllabus; and 2) the contents must be relevant to problem-based training. The results have indicated that the ELS is effective and helpful to the students, and there are plans to expand the contents of the system. Further refinements of the system should make it even easier to use for both students and teachers.
