Orthod Craniofac Res 2023; 26 Suppl 1:210-220. [PMID: 37184946 PMCID: PMC10646151 DOI: 10.1111/ocr.12669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 04/10/2023] [Accepted: 04/19/2023] [Indexed: 05/16/2023]
Abstract
PURPOSE/OBJECTIVES Multimedia presentations and online platforms are used in dental education. Though studies indicate the benefits of video-based lectures (VBLs), data regarding user reception and optimal video features in dental education are limited, particularly on Web 2.0 platforms like YouTube. Given increasing technology integration and remote learning, dental educators need evidence to guide implementation of YouTube videos as a freely available resource. The purpose of this study is to determine video metrics, viewership and format efficacy for dental education videos. METHODS First, a cross-sectional survey was conducted of viewers (N = 683) of the Mental Dental educational videos on YouTube. Analytics were evaluated for 677 200 viewers to assess audience demographics, retention and optimal video length. Second, a randomized crossover study was conducted of dental students (N = 101) who watched VBLs in either slideshow or pencast formats and were tested on content learning to compare format efficacy. RESULTS Most viewers of Mental Dental videos were dental students (44.2%) and professionals (37.8%) who would likely recommend the platform to a friend or colleague (Net Promoter Score = 82.1). Audience retention declined steadily at 1.34% per minute, independent of video length. Quiz performance did not differ between slideshow and pencast videos, with students having a slight preference for slideshows (P = 0.049). CONCLUSIONS Dental students and professionals use VBLs and are likely to recommend them to friends and colleagues. There is no optimal video length to maximize audience retention and lecture format (slideshow vs. pencast) does not significantly impact content learning. Results can guide implementation of VBLs in dental curricula.

Crowe HL, Woolley SM. Dental students' experience of conscious sedation: A qualitative review of student reflections. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2022; 26:197-205. [PMID: 33838059 DOI: 10.1111/eje.12688] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 01/06/2021] [Accepted: 04/02/2021] [Indexed: 06/12/2023]
Abstract
INTRODUCTION The UK General Dental Council (GDC) requires dental graduates to competently identify, manage and refer patients with dental pain and anxiety. This study aimed to explore sedation training experience quantitatively and qualitatively through individual reflective logs. MATERIALS & METHODS A single-centred mixed-methods evaluation of teaching, within a UK university conscious sedation department. Fourth-year dental students undertook lectures and supervised clinical sessions following the undergraduate curriculum. Patient attendance patterns, individual experience and group experience were analysed descriptively. Reflective log sheets were analysed by Thematic Framework Analysis. RESULTS Seventy-two students participated. Of 153 booked patients, 79 (51.6%) attended of which 74 (48.4%) were treated by undergraduates. The mean performed inhalation sedation and intravenous sedation cases per student were 1 and 0.8, respectively. Three students (4%) assisted only. Group experience varied. Three themes arose from reflections: consolidation of theory and learning; confidence through experience; and responding to challenges. DISCUSSION Whilst experience quotas were not met, GDC requirements for increasing students' knowledge and confidence within CS were met. Practical experience enhanced learning. "Hands-on" experience was most valuable for self-reported confidence but learning by proxy also aided development. Students recognised challenges, but not the implications for themselves or their career. Strategies to reduce barriers to experience require research. CONCLUSION Whilst variable, all students were provided learning opportunities. Physical experience gave the greatest confidence. Opportunities afforded by the undergraduate curriculum allowed students to learn and develop through consolidation of theory, response to challenges and ultimately the gaining of confidence.

JMIR MEDICAL EDUCATION 2021; 7:e25506. [PMID: 33941512 PMCID: PMC8128048 DOI: 10.2196/25506] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 12/28/2020] [Accepted: 05/03/2021] [Indexed: 05/27/2023]
Abstract
BACKGROUND During the acute COVID-19 pandemic, physical access to the University Medical Center Göttingen was restricted for students. For the first time at our dental school, theoretical knowledge was imparted to students via asynchronous online screencasts and discussed via synchronous video meetings only. OBJECTIVE We aimed to assess the acceptance and effectiveness of distance education as a new teaching format for theoretical knowledge within the preclinical course in Operative Dentistry (sixth semester of the undergraduate dental curriculum in Germany). METHODS The phantom course comprised distance education (first phase, 11 weeks) and subsequent on-site practical demonstrations and training (second phase, 10 weeks). All theoretical knowledge was taught via online screencasts during distance education (except for the first week, 3 screencasts were uploaded per week resulting in a total of 30 screencasts). Until the end of the term, all students (N=33) were able to view the screencasts for an unlimited number of times. Theoretical knowledge was assessed in a summative examination after practical on-site teaching. Acceptance and effectiveness of the new curriculum and distance education were also measured based on an evaluation survey and students' self-perceived learning outcome, which was compared to the outcome from the two pre-COVID-19 terms. RESULTS Each screencast was viewed by a mean of 24 (SD 3.3) students and accessed a mean of 5.6 (SD 1.2) times per user (ie, by students who accessed the respective screencast at least once). During distance education, the number of accesses showed a linear trend over time. During the practical training phase, screencast views declined and increased again prior to the examination. Screencasts covering topics in Cariology, Restorative Dentistry, and Preventive Dentistry were viewed by more students than screencasts covering topics in Endodontology or Periodontology (both P=.047). Examination items in Periodontology showed inferior results compared to the other topics (P<.001). Within the different topics, students' self-perceived learning outcome did not differ from that during the pre-COVID-19 terms. Although most students agreed that the presented screencasts contributed to their learning outcome, pre-COVID-19 term students more strongly felt that lectures significantly contributed to their learning outcome (P=.03). CONCLUSIONS Screencasts showed high acceptance and effectiveness among the students but were not used as a learning tool by all students. However, students who viewed the screencasts accessed each screencast more frequently than they could have attended a conventional lecture. Screencast views were mostly due to intrinsic motivation.

Abstract
PURPOSE Student engagement is typically measured by class attendance and questionnaires. Learning management systems (LMS) provide additional sources of objective data that can evaluate student performance. This study compared dental students' self-report of course video viewing with LMS data. METHODS Dental students in a 2018 flipped pediatric dentistry course were given a questionnaire after course completion that captured self-reported course video viewing. Student data and time spent on videos were extracted from the LMS and matched to the questionnaire. McNemar's test evaluated differences between self-reported and matching LMS data. RESULTS Of the 109 enrolled students, 99 (91%) completed the questionnaire. Most students self-reported that they watched more than half of the videos (71%), re-watched at least once (89%), and watched at times other than 8 a.m.-5 p.m. (80%). Of the 104 students with data from the LMS, 40% of students watched more than half of the videos, 49% re-watched at least one video, and 60% watched between 8 a.m.-5 p.m. LMS data showed 14 (13%) students did not watch any videos. Significant differences were found between self-reported video viewing and matched LMS video data in (1) percentage of videos watched, (2) number of times videos were re-watched, and (3) most frequent time for watching the videos (p < 0.001 for all). CONCLUSION Technology is a tool that helps instructors more accurately track students' study habits compared to observation or self-report. When evaluating time spent watching videos via an LMS, students tend to overestimate the amount of viewing time.

Abstract
INTRODUCTION Undergraduate dental curriculum consisting of digital tools is essential in today's era of modern dentistry. The aim of this study was to evaluate final-year undergraduate dental students' perception of using intraoral scanners and the feasibility of increasing exposure to intraoral scanners in their undergraduate programme. MATERIALS AND METHODS Forty students volunteered to complete one maxillary conventional and optical impression (TRIOS 3, 3Shape A/S). Questionnaires were used to assess their familiarity, perceived confidence levels, difficulties and user-friendliness of each technique using a visual analogue scale prior to and after experiencing each impression technique. RESULTS Students felt more familiar with conventional (C) than digital (D) impressions (P = .00). Their pre-confidence level was also higher with the conventional method (C: 80.9 ± 15.5; D: 39.6 ± 25.5); however, the post-confidence level significantly increased for the digital impression technique (P = .00). Participants perceived conventional technique to be easier (P = .02) and faster than optical impressions (P = .03). User-friendliness of the intraoral scanner scored moderate (67.7 ± 22.9). The difference in the mean total working time was not significant (P = .05). Forty per cent of participants indicated that they preferred using the digital impression technique. CONCLUSIONS Although final-year undergraduate students still perceived the conventional impression technique to be easier and faster than digital scanning, there was a significant increase in the level of confidence by this cohort after only one occasion of clinical optical impressions. Undergraduate dental students are ready to uptake new technology, and it should be strongly considered to incorporate more digital scanning during their training.

Abstract
The aim of this systematic review was to investigate current penetration and educational quality enhancements from digitalization in the dental curriculum. Using a modified PICO strategy, the literature was searched using PubMed supplemented with a manual search to identify English-language articles published between 1994 and 2020 that reported the use of digital techniques in dental education. A total of 211 articles were identified by electronic search, of which 55 articles were selected for inclusion and supplemented with 27 additional publications retrieved by manual search, resulting in 82 studies that were included in the review. Publications were categorized into five areas of digital dental education: Web-based knowledge transfer and e-learning, digital surface mapping, dental simulator motor skills (including intraoral optical scanning), digital radiography, and surveys related to the penetration and acceptance of digital education. This review demonstrates that digitalization offers great potential to revolutionize dental education to help prepare future dentists for their daily practice. More interactive and intuitive e-learning possibilities will arise to stimulate an enjoyable and meaningful educational experience with 24/7 facilities. Augmented and virtual reality technology will likely play a dominant role in the future of dental education.
