The use of video-clips as a teaching aide

Exploring pedagogical approaches in crown preparation: a randomized controlled trial comparing the efficacy of instructional videos and live demonstrations

BACKGROUND

This study aimed to compare the efficacy of instructional videos and live demonstrations in crown preparation training for preclinical dental students.

METHODS

A randomized controlled trial was conducted over 12 months with 96 final-year Bachelor of Dental Surgery (BDS) students. Participants were randomly allocated into three groups: Group A (instructional video), Group B (live demonstrations), and Group C (hybrid approach). Each group underwent training in porcelain-fused-to-metal tooth preparation through their respective methods. Performance was assessed using a standardized scoring chart, while satisfaction and perceptions were evaluated using a 5-point Likert scale. Data were analyzed using Chi-square and paired t-tests, with statistical significance set at p < 0.05.

RESULTS

The group comparisons revealed significant differences in perceptions between Group A and Group B regarding stress levels during crown preparation (p = 0.013) and the adequacy of preclinical training (p = 0.034), with Group B showing higher satisfaction. However, no significant differences were found between Groups A and C or between Groups B and C (p > 0.05). Exercise scores across all groups showed no significant variation (p > 0.05), indicating comparable performance. Knowledge assessment revealed that while a majority of students correctly identified key concepts such as finish line depth, bur choices, and cusp reduction, 10-16% of students held misconceptions in areas like margin design and reduction ranges.

CONCLUSION

This study demonstrates that instructional videos, live demonstrations, and a hybrid approach are all effective methods for teaching crown preparation skills to preclinical dental students. The slight advantage of the hybrid approach suggests that combining different teaching methods may provide the most comprehensive learning experience. Future studies should explore the long-term impact of these methods on clinical performance.

TRIAL REGISTRATION

The study was registered at clinicaltrials.gov, identifier NCT06426095.

Face-to-face versus 360° VR video: a comparative study of two teaching methods in nursing education

BACKGROUND

The practical sessions during skills laboratory simulation or clinical simulation are cores of nursing education. For this, different modalities have been devised to facilitate psychomotor skills learning. One of the commonly used educational material or instructional method to supplement skills learning across various disciplines is video-based teaching method. The opportunities of traditional two-dimensional video might be limitless and maximized with 360º virtual reality (VR) video, which offers immersive experience. This study incorporates 360º VR video into skills laboratory training as an alternative approach to face-to-face procedure demonstration.

METHODS

An open-label, parallel (1:1), randomized controlled trial study was conducted among third-year undergraduate nursing students at Hiroshima University, Japan. The nursing students were block-randomized into 360º VR video and face-to-face demonstration group. After a 3-hour theoretical class of patient management on ventilator and closed-suction principles of mechanically ventilated patients in an Intensive Care Unit focused class, the 360º VR group watched the 360º VR video of closed tracheal suction (including oral) using the head-mounted display of Meta Quest 2 individually, while the face-to-face group attended the instructor's demonstration. A week after the skills laboratory, the students' psychomotor skills, knowledge, satisfaction, confidence were evaluated; the 360º VR video group's perception was explored; Wilcoxon rank-sum test was used to compare the two groups.

RESULTS

A total of 57 students were analyzed; 27 students in the 360º VR video group and 30 students in face-to-face group. There were no statistically significant differences between both groups in skills, knowledge, and confidence. However, the face-to-face group had higher satisfaction level than the 360º VR group; this difference was statistically significant. In the 360º VR video group, 62% agreed that VR makes learning more interesting; more than half of students (62.5%) experienced VR sickness symptoms, and "feeling of drunk" is the highest. The students appreciated the ready to use, immersiveness, and realism; however, symptoms and discomfort, burdensomeness, and production limitations were improvements recommended.

CONCLUSION

Although face-to-face demonstration is the established method of teaching psychomotor skills to nursing students, the use of 360º VR video could achieve similar learning effect as an alternative approach.

Undergraduates' comparative assessment, utilizing a structured rubric, of hands-on versus video-supported presentation in class II cavity preparation

BACKGROUND

Dental education is considered as a complex, challenging and often stressful educational procedure. Acquisition of psychomotor skills by undergraduate students is an important step in many health professions to become a successful professional. During under graduation, class II cavity preparation exercise is of utmost important in dentistry.

OBJECTIVE

To compare class II cavities prepared by students after hands-on live demonstration and pre-recorded video demonstration using well-organised evaluation rubrics.

METHOD

Preclinical dental students (n= 50) were divided into two groups. The students in group I (n= 25) attended a hands-on live demonstration performed by one faculty while students in group II (n= 25) watched a 15-minute pre-recorded procedural video on the projector. Both groups were appealed to prepare class II cavity for amalgam involving disto-occlusal surface of mandibular second molar articulated on jaw model (TRU LON study model, Jayna industries, Ghaziabad U.P., India). Following completion of the preparations, all teeth were collected, and labelled grades of prepared cavities were given according to prespecified rubrics. The data of scores were presented as means and standard deviation. Statistical analysis of data was executed using SPSS software. A paired t-test was used to compare scores between groups.

RESULTS

The study shows that the video-supported demonstration of a cavity preparation was better than the live hands-on demonstration. A higher mean response for the procedural video group was found compared to the live demonstration group (p= 0.000133).

CONCLUSION

Pre-recorded video-supported demonstration along with guidance by a tutor may be a viable alternative to hands-on live demonstration in cavity preparation procedures during undergraduate dental training. Moreover, rubric methods can be implemented in the teaching of various preclinical exercises for conservative dentistry and endodontics.

[ZApprO versus ZÄPrO: results of a first comparative study]

BACKGROUND

More than 60 years after the enactment of the first Licensing Regulations for Dentists (ZÄPrO), a new Licensing Regulations for Dentists, the ZApprO, was implemented in 2020. The aims of this study were to evaluate and compare the "Course in Technical Propaedeutics" (TPK) with the course "Dental Propaedeutics with a Focus on Dental Technology" (ZPDT), which are based on different legal foundations.

METHODS

The following parameters were compared after completion of the courses: (1) theoretical and practical knowledge, (2) regular department-internal learner evaluation, and (3) special evaluation of learning conditions by the learners and (4) by the instructors. The theoretical and practical exams and the questionnaires were analyzed in terms of their test-statistical characteristics (difficulty, discrimination index, internal consistency). Group comparisons between TPK and ZPDT were conducted using t‑tests for independent groups.

RESULTS

Significant differences were only detected in the students' evaluation of their learning conditions, with theoretical and practical knowledge transfer being rated lower in the TPK than in the ZPDT.

DISCUSSION

The comparable results of the knowledge assessments and the regular learner evaluation, triangulated with the comprehensive learner and instructor evaluation, allowed a broad assessment of both courses. The significant differences identified provide opportunities for optimization of the newly implemented ZPDT course.

Effect of an endodontic e-learning application on students' performance during their first root canal treatment on real patients: a pilot study

BACKGROUND

E-learning has found its way into dental teaching in general and endodontic teaching in particular. The present study aimed to implement a newly developed multimedia learning application and assess its effect on students' first root canal treatment on real patients. With the COVID-19 outbreak, the application's performance was investigated during the pandemic.

METHODS

A total of 138 students in the initial clinical endodontic course participated in this study. The control group (n = 49) followed the traditional curriculum, including practice on artificial teeth and face-to-face teaching events. In addition to the traditional curriculum, test group 1 (n = 54) had access to an endodontic e-learning application containing videos demonstrating artificial teeth and patient cases. With the COVID-19 outbreak, test group 2 (n = 35) had no face-to-face teaching; however, endodontic patient treatments were included. The quality of students' first root canal treatment on real patients was compared using performance and radiographic assessment items. Statistical analysis was done using Kruskal-Wallis and chi-squared tests. Test groups received a questionnaire to assess the learning application. Test group 2 also completed a COVID-19-specific survey to measure students' perceptions of how the pandemic affected their endodontic education.

RESULTS

The results of endodontic treatments were significantly better for test group 1 (P < 0.001) and 2 (P < 0.001) than for the control group. Likewise, there were significantly fewer treatment errors in test group 1 (P < 0.001) and 2 (P < 0.001). No significant differences were found between test groups 1 and 2. Students of the test groups positively evaluated the e-learning application. Students of test group 2 expressed their fear of negative impacts on their course performance.

CONCLUSION

The e-learning application was well-received and seemed to improve endodontic education. The results imply that the quality of education may be maintained by implementing e-learning to compensate for face-to-face teaching. As no difference was found between online and face-to-face teaching, students' and lecturers' concerns that endodontic education is suffering because of the pandemic may be eased.

Using 360-degree video for teaching emergency medicine during and beyond the COVID-19 pandemic

OBJECTIVE

During the COVID-19 pandemic, emergency medicine (EM) teachers had to employ innovative methods to ensure the continuity of the education process. The purpose of this study was to explore the adequacy of the 360-degree video (video 360) technology in EM education in the context of: (a) students' attitudes towards the video 360; (b) students' academic performance in their required examination at the end of the EM course compared to the assessment results of students from the previous academic year.

METHODS

A mixed-method research project enrolled the fourth-year medical students who attended the required EM course during the first semester of the academic year 2020-2021 when all activities with undergraduate students went online and teaching scenarios recorded in the video 360 format were employed. Data collection was two-fold: (a) anonymous questionnaires, complemented with basic YouTube analytics; (b) multiple-choice questionnaires (MCQ) and oral examination, contrasting the results with those in 2019-2020. Data analysis used descriptive statistics and non-parametric methods.

RESULTS

Seventy-nine students (53 females and 26 males) participated in the project and all completed the EM course. Students' interest in and their acceptance of the video 360 technology were high (total scoring in the upper 20% of the respective scales), with consistently good performance in two parallel, independent, interview-based oral/practical evaluations (Spearman correlation coefficient R = 0.665, p < .001). The majority scored over 90% in the summative MCQ, with higher values compared to their colleagues' during the previous academic year (with on-site teaching): scoring percentages with mean ± standard deviation of 92.52 ± 4.57 and 76.67 ± 18.77, respectively.

CONCLUSION

Our project showed that the video 360 scenarios were effective in teaching EM. In the long term, employing this accessible and inexpensive educational approach would add value to on-site training by enriching the exposure to a specific ED environment.KEY MESSAGESMedical students valued the 360-degree video scenarios as contributing substantially to their EM knowledge and preparedness.Examination results confirmed the 360-degree video scenarios as viable in EM teaching.The 360-degree video technology would be a sustainable solution for hybrid medical teaching in the long term.

Effect of a Procedural Video on the Practical Fixed Prosthodontic Performance and Stress among Preclinical Dental Students

Objective The purpose of this article was to analyze the effect of an instructional video on practical tutorial and to ascertain whether an instructional video improves students’ performance on practical performance and reduces the stress associated with learning.

Materials and Methods A randomized controlled trial was conducted on a group of 78 first-year students. A pretest was conducted by administering questionnaires to evaluate the interest in the use of videos as well as the level of stress. Students were randomly assigned into two groups: control and test. Students assigned to the control group received conventional teaching, while the experimental group received both conventional teaching and watched a video. Thereafter, a satisfaction questionnaire was distributed to each of the groups, and they were awarded a grade.

Results A total of 98.7% of students wished to learn fixed prosthodontics through instructional videos, as they believed that the videos could reduce their worry and stress levels. At the end of the first tutorial, the total grade was significantly lower for the test group ( p = 0.003). However, the subjective value of stress was significantly lower in the test group ( p = 0.0007) as well as the subjective value of tutorial difficulty ( p = 0.0004). Students felt that they better understood the objectives of the tutorial “thanks to the video” ( p = 0.0001).

Conclusion This study did not reveal any improvement in terms of performance when an instructional video was used for tutorials in comparison with the conventional teaching method. However, the results show a reduction in the level of stress.

Education Technology in Orthodontics and Paediatric Dentistry during the COVID-19 Pandemic: A Systematic Review

Over the last decade, medical education changed from traditional teaching methods to telematic and networking scholar and e-learning approach. The objective of the present systematic review was to evaluate the effectiveness and teachers/student's acceptability of e-learning applied to the field of orthodontics and paediatric dentistry. A database search of the literature was conducted on PubMed and Embase databases from January 2005 to May 2021. A total of 172 articles were identified by the electronic search, while a total of 32 papers were selected for qualitative analysis. Overall, 19 articles investigated the effectiveness of e-learning, and no difference of acceptability was reported between e-learning and traditional methods for a wide part of the articles selected. A total of 25 papers provided a satisfaction questionnaire for learners and all were positive in their attitude towards e-learning. The results showed that e-learning is an effective method of instruction, complementing the traditional teaching methods, and learners had a positive attitude and perception. The evidence of the present study reported a high level of acceptability and knowledge level of e-learning techniques, compared to frontal lecture methods, in the fields of orthodontics and paediatric dentistry.

Remote Teaching in a Preclinical Phantom Course in Operative Dentistry During the COVID-19 Pandemic: Observational Case Study

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.

Use of 360° virtual reality video in medical obstetrical education: a quasi-experimental design

BACKGROUND

Video-based teaching has been part of medical education for some time but 360° videos using a virtual reality (VR) device are a new medium that offer extended possibilities. We investigated whether adding a 360° VR video to the internship curriculum leads to an improvement of long-term recall of specific knowledge on a gentle Caesarean Sections (gCS) and on general obstetric knowledge.

METHODS

Two weeks prior to their Obstetrics and Gynaecology (O&G) internship, medical students were divided in teaching groups, that did or did not have access to a VR-video of a gCS. Six weeks after their O&G internship, potentially having observed one or multiple real-life CSs, knowledge on the gCS was assessed with an open questionnaire, and knowledge on general obstetrics with a multiple-choice questionnaire. Furthermore we assessed experienced anxiety during in-person attendance of CSs, and we asked whether the interns would have wanted to attend more CSs in-person. The 360° VR video group was questioned about their experience directly after they watched the video. We used linear regression analyses to determine significant effects on outcomes.

RESULTS

A total of 89 medical students participated, 41 in the 360° VR video group and 48 in the conventional study group. Watching the 360° VR video did not result in a difference in either specific or general knowledge retention between the intervention group and the conventional study group. This was both true for the grade received for the internship, the open-ended questions as well as the multiple-choice questions and this did not change after adjustment for confounding factors. Still, 83.4% of the 360° VR video-group reported that more videos should be used in training to prepare for surgical procedures. In the 360° VR video-group 56.7% reported side effects like nausea or dizziness. After adjustment for the number of attended CSs during the practical internship, students in the 360° VR video-group stated less often (p = 0.04) that they would have liked to attend more CSs in-person as compared to the conventional study group.

CONCLUSION

Even though the use of 360° VR video did not increase knowledge, it did offer a potential alternative for attending a CS in-person and a new way to prepare the students for their first operating room experiences.

Hands-on live demonstration vs. video-supported demonstration of an aesthetic composite restoration in undergraduate dental teaching

PURPOSE/OBJECTIVES

Live hands-on demonstration of dental procedures is a central format in undergraduate dental teaching. It captures the immediacy of the clinical situation and allows for direct communication between instructor and students, but it also requires an experienced instructor who is able to handle both the performed treatment and its visualization alongside the actual teaching. The aim of the present work is to compare the hands-on demonstration of a class IV composite restoration to a teaching format where the instructor guided the students through a prerecorded procedural video of the same treatment.

METHODS

The effect of both interventions on the students' self-perceived learning outcomes was analyzed by questionnaires (response rate 100%) in a randomized controlled double-blind (participants, outcome assessor) parallel group design (September 10 to October 3, 2019). In-class discussions were explored qualitatively by thematic analysis.

RESULTS

Both teaching formats increased the students' self-reported motivation, self-efficacy, and patient-centeredness in a similar way, with no significant differences between interventions. During in-class discussions, both the instructor and the students were more active in the video group. In contrast to the hands-on group, discussions in the video group also involved patient-related topics, such as aesthetics and general health. The video-supported teaching format considerably reduced the amount of time spent on optimizing the visualization of the performed treatment.

CONCLUSION

Video-supported instructor-guided demonstrations may represent a promising teaching format as an alternative to live hands-on demonstrations of dental procedures in undergraduate dental education.

The impact of an electronic guide on students' self-directed learning in simulation clinic

INTRODUCTION

Simulation training on high-fidelity simulated models have been used to provide a safe and effective training platform for dental students to develop the skills necessary to treat patients. To surpass challenges of traditional pedagogies in simulation training and reinforce self-directed learning, a bespoke computer application, PerioPal, was designed to complement training of dental students in periodontal instrumentation.

MATERIALS AND METHODS

This study evaluated the impact of PerioPal on a cohort of 92 second-year dental students at an Australian University. During the first semester in 2019, they received traditional simulation periodontal instrumentation training (control semester). In the following semester, PerioPal was implemented as a technological teaching adjunct (intervention semester). Student perceptions of their learning experiences were gathered through a qualitative and quantitative questionnaire. Impact on student performance was evaluated through comparing periodontal instrumental assessment results in control and interventionsemesters.

RESULTS

With introduction of PerioPal, students perceived that the simulation clinic learning environment, better contributed to the speed at which they learnt new instrumentation as well as being able to self-pace their work. They commented that instructional videos and independent learning were most beneficial. Interestingly, students suggested that PerioPal aided their preparation for theoretical assessments more than their practical assessments. After introduction of PerioPal a minor improvement of average practical assessment marks was observed but could not be statistically confirmed as significant.

CONCLUSION

Although the computer-supported learning did not lead to improvement of the students' practical performance a positive effect on the student self-paced learning experience and engagement in simulated environment were observed.

Live lectures and videos do not differ in relation to learning outcomes of dental ergonomics

OBJECTIVES

This study aimed to compare the knowledge attained by third-year dental students in physical ergonomics altering live lectures and videos in teaching. The second aim was to investigate implementation of the theoretical knowledge on ergonomics into practice.

MATERIAL AND METHODS

Forty-five students divided into two groups attended a live lecture (45 min) or viewed videos (45 min). After the first teaching session, the groups changed parts. All students answered a questionnaire with 13 true or false-questions on ergonomics at baseline and immediately after both teaching sessions. Friedman's test and Wilcoxon signed rank test were used to compare questionnaire scores of the student groups. Additionally, we photographed 17 randomly selected students 3 months after baseline during a simulation workshop on endodontics. We analyzed the photographs for ergonomic postures using a specific 12-point checklist.

RESULTS

At baseline, no difference in the knowledge between the two groups was discovered, when both scored 72%. After the first teaching session, significant improvement in both groups (p < .05) was found; and there was no statistically significant difference in the scores between the groups (88% in the lecture-first and 82% in the video-first group). After the second teaching session, the scores were similar in both groups. Overall all improvement in both groups was significant (p < .001). The photograph analysis showed half of the postures being in accord with the ergonomic guidelines.

CONCLUSIONS

Both live lectures and videos showed similar outcomes in teaching ergonomics. Implementation of the knowledge on ergonomics is insufficient. Videos provide an easy-to-organize alternative to live lectures in teaching dental ergonomics. New means are needed to have dental students implement their knowledge on ergonomics into practice.

Medical professionalism videos on YouTube: Content exploration and appraisal of user engagement

Background

Social media has become the fastest growing platform for sharing and retrieving information and knowledge, and YouTube is one of the most popular and growing sources of health and educational information video-sharing website. But, videos on this open platform are not peer-assessed, therefore, the accessible data should be adequately assessed. Till date, no exploration and analysis for assessing the credibility and usefulness of Medical professionalism videos available on YouTube are conducted.

Objective

To analyze the video sources, contents and quality of YouTube videos about the topic of medical professionalism.

Methods

A systematic search was accomplished on YouTube videos during the period between March 1, 2020 and March 27, 2020. The phrases as significant words used throughout YouTube web search were ‘Professionalism in Medical Education’, Professionalism in medicine’, ‘Professionalism of medical students’, ‘Professionalism in healthcare’. ‘Teaching professionalism’, ‘Attributes of professionalism’. The basic information collected for each video included author’s/publisher’s name, total number of watchers, likes, dislikes and positive and undesirable remarks. The videos were categorized into educationally useful and useless established on the content, correctness of the knowledge and the advices. Different variables were measured and correlated for the data analysis.

YouTube website was searched the using keywords ‘Professionalism in Medical Education’, Professionalism in medicine’, ‘Professionalism of medical students’, ‘Professionalism in healthcare’. ‘Teaching professionalism’, and ‘Attributes of professionalism’.

Results

After 2 rounds of screening by the subject experts and critical analysis of all the 137 YouTube videos, only 41 (29.92%) were identified as pertinent to the subject matter, i.e., educational type. After on expert viewing these 41 videos established upon our pre-set inclusion/exclusion criteria, only 17 (41.46%) videos were found to be academically valuable in nature.

Conclusion

Medical professionalism multimedia videos uploaded by the healthcare specialists or organizations on YouTube provided reliable information for medical students, healthcare workers and other professional. We conclude that YouTube is a leading and free online source of videos meant for students or other healthcare workers yet the viewers need to be aware of the source prior to using it for training learning.

Digital Undergraduate Education in Dentistry: A Systematic Review

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.

The Effect of Live-Video Demonstration on Dental Students' Orthodontic Bending Performance

The aims of this study were to evaluate the effects of a live-video teaching tool on the performance of dental students in bending an orthodontic vestibular arch and to assess the students' perceptions of the technology. All 135 fourth-year dental students in the 2018 academic year at Hacettepe Dental School, Ankara, Turkey, were invited to participate in the study; after exclusions, the remaining 116 were randomly divided into two demonstration cohorts. These students had no prior experience bending an orthodontic wire. Cohort 1 (control, N=58) was shown a conventional live demonstration of the orthodontic bending of a vestibular arch, and Cohort 2 (experimental, N=58) was shown a live-video demonstration of the same procedure. Both cohorts saw the demonstration before beginning the exercise and were evaluated afterwards on their performance of the procedure. In addition, the students' perceptions of the demonstration techniques were collected with a questionnaire. The results did not show any significant differences in the students' bending scores between the control and experimental cohorts (p=0.767). The median values on the questionnaire indicated almost no statistically significant difference in responses between the cohorts. The only significant difference was that Cohort 1 had a higher percentage who answered "yes" they would like to rewatch the demonstration than did Cohort 2 (p=0.024). In this study, the live-video technique was found to be as effective as a conventional live demonstration for orthodontic practical education, suggesting that either technique could be used as an appropriate method for training in orthodontic wire bending.

Comparison of Live-Video and Video Demonstration Methods in Clinical Orthodontics Education

The aim of this study was to compare the effectiveness of live-video and video demonstration methods in training dental students in orthodontic emergency applications. A total of 105 fifth-year dental students at a dental school in Turkey participated in the study in 2018. A pretest was given to the students to evaluate their level of knowledge about band cementing and re-bonding of brackets. Subsequently, two clinical applications were demonstrated with either live-video or video demonstration. During the live-video demonstration, the lecturer gave information about the steps of the procedure while performing the clinical application on the patient using a camera attached to the loupes. The students were able to see the process on the screens. During the video demonstration, previously recorded videos of those clinical applications were shown, and information was given to students in a classroom. On the next day, posttests were given to the students. The posttest also asked students to give their opinions about both methods. The results showed that the mean posttest scores on the video demonstration were significantly higher than on the live-video demonstration. However, no significant difference between the demonstration methods was found with regard to increase of scores from pre- to posttest. Most students preferred use of the two demonstrations together for education in the clinical orthodontics lecture. This study found that the two demonstration methods had comparable effects on increasing students' level of knowledge. However, from the students' perspective, the two should be used together to achieve the highest effect.

Enhancing Dental Carving Skills of Preclinical Dental Hygiene Students Using Online Dental Anatomy Resources

Background:

A key role of dental carving is enhancing manual proficiency and dexterity of dental hygiene students. Yet, utilizing Supplementary Online Dental Anatomy Resources (SODAR) as a supportive teaching approach has demonstrated the ability to improve carving skills.

Objective:

This study aims to examine the effectiveness of SODAR training in improving the quality of dental carving skills and knowledge among preclinical Saudi male students in Saudi Arabia.

Methods:

A basic double-blinded randomized controlled trial of 30 preclinical Saudi dental male students was conducted between January and April 2019. Participants were classified into an experimental group that received SODAR training (n= 15) and a control group comprising students who did not receive SODAR training (n= 15). Thet-test and Fisher’s exact test were performed to assess differences in theoretical knowledge between the two groups. While Cohen’s d test,t-test, and Pearson correlation were conducted to evaluate differences in students’ dental carvings.

Results:

Students with SODAR training performed better on practical carving sessions than those without intervention (P-value < 0.001). However, SODAR intervention had no significant effect on the theoretical knowledge evaluations in both the groups.

Conclusion:

SODAR training demonstrated its ability to support students learning in practical carving sessions; however, no effect on theoretical knowledge was observed. Future research should focus on factors that impact carving teaching strategies, including the quality and depth of online learning content, students’ perceptions of online learning, and experiences of teachers who run the online resources.

The availability of open-access videos offered by dental schools

BACKGROUND

The Internet has become an established learning tool in dental education where students can access online videos on a range of dental subjects. However, finding reliable peer-reviewed content is not straightforward.

AIM

To evaluate the video content offered by UK and Republic of Ireland (RoI) Dental Schools on their YouTube channels and public websites.

METHODS

Free videos offered on UK and RoI Dental schools websites and YouTube channels were watched and set according to its purpose, as educational or non-educational. The number of views, length, category and date of publication were analysed.

RESULTS

A total of 627 videos offered by dental courses were evaluated. Videos were available on 83% of the websites, but only 9% was educational content. Dental courses YouTube channels received more than 2.3 million views, but less than 5% of the material offered is educational. Instructional videos found on the websites (3.2 min) were shorter than those found on YouTube (8.5 min) (P = .03). The majority of the videos, provided by Universities, were not educational and focused on promoting the dental courses. Most websites have demonstrated a password-protected area where quality content may be offered.

CONCLUSION

Students wishing to watch instructional videos will find limited educational content provided by UK and RoI dental courses. Therefore, they are likely to access course-related material elsewhere on the Internet that may not be necessarily peer-reviewed.

A critical review of obstetric and gynecological physical examination videos available on YouTube: Content analysis and user engagement evaluation

BACKGROUND

Video-sharing website "YouTube" is a growing source of healthcare information. But, the videos uploaded on this open platform are not peer reviewed, therefore, the information available needs to be sufficiently evaluated. No studies have been conducted to evaluate the authenticity and utility of obstetrics and gynecology (Obs/Gyne) physical examination YouTube videos. This study was performed to analyze the sources, contents, and quality of videos about the Obs/Gyne clinical examination available on YouTube.

METHODS

A systematic search was performed on YouTube website using the following key words: "OBSTETRIC," "GYNECOLOGICAL," "SPECULUM OBSTETRIC," "OBSTETRIC CLINICAL," "BIMANUAL PELVIC," and "EXAMINATION" to analyze the sources, contents, and the quality of YouTube videos about the Obs/Gyne clinical examination during the period between November 2015 and March 2017. The videos were classified into educationally useful and useless based on the content, accuracy of the knowledge, and the demonstration.

RESULTS

Out of total 457 screened videos, 176 (38.51%) videos met the pre-set inclusion criteria. After review, out of 176 pertinent videos, 84 (47.7%) videos were found educationally useful, and out of these 84 useful videos, only 29 (34.5%) were highly educational in nature.

CONCLUSION

YouTube videos showed variable educational value. Only, a small number of videos were identified as useful and can be used by the medical students for self-directed learning and by the clinical teachers for educational purposes or other academic activities.

Pedagogical Evaluation of Digital Technology to Enhance Dental Student Learning

Objective A large number of digital tools supporting students have emerged over recent years which are encouraged in tutoring. A study conducted at the University of Montpellier (France) among 3rd, 4th, and 5th year dentistry students aimed primarily to identify the type of pedagogical support the students preferred according to their discipline. The secondary aim was to evaluate the student satisfaction after establishing a new pedagogical support.

Materials and Methods A total of 165 questionnaires were completed. The main questions concerned pedagogical use of information technology and multimedia tools, choice of dentistry disciplines most justifying their use, and pedagogical gaps in these disciplines. Next, a program of pedagogical videos was developed for the most corresponding discipline. A satisfaction survey was finally conducted.

Results Nearly 95.7% of students found online classes and E-learning via the virtual learning environment useful, with the most requested type being video. Demand was stronger in conservative dentistry and endodontics (27%), prosthetics (19%), and periodontology (18%). The most apprehended disciplines were endodontics in the 3rd year, endodontics and prosthetics in the 4th year, and prosthetics in the 5th year. Regarding satisfaction, 100% of students appreciated these videos and 99.4% considered they fulfilled expectations.

Conclusion All students requested videos, especially for clinical subjects such as endodontics. With digital technology, our world is experiencing a technological revolution resulting in many daily life changes. With students evolving in a digitally saturated society, our ways of learning and teaching need rethinking. Digital technology can help improve learning effectiveness and develop pedagogical practices more adapted to today's students.

Dental students' perceptions of an online learning

Objectives

To identify the readiness of students for online learning, to investigate their preference and perception, and to measure the quality of online tutorials.

Materials and methods

A 14-statement questionnaire was administered to fourth year undergraduate dental students in male campus at King Saud University who completed preclinical orthodontic course. The students responded to each statement by using Likert scale.

Results

The results reveal a high agreement of students (27.8–31.5% agree and 38.9–50% strongly agree) on a possession of necessary computer skills and access to internet. 59.2% and 64.8% of the students replied that online flash lectures and procedural videos were helpful to their learning, respectively. With respect to students' learning preferences, few students preferred online flash lectures (31.5%) and procedural videos (17.1%). Most students (38.9% agree and 31.5% strongly agree) preferred a combination of traditional teaching methods and online learning.

Conclusion

Overall, student attitudes were positive regarding online learning. The students viewed online learning helpful as a supplement to their learning rather than a replacement for traditional teaching methods.

Bespoke video vignettes - an approach to enhancing reflective learning developed by dental undergraduates and their clinical teachers

This study explores the selective use of video as a medium to support reflective processes as related to dental undergraduate learning. With the objective of developing and enhancing high-quality adult dental care, the use of compiled video materials created in an undergraduate clinical setting was investigated. Video cameras were used to capture elements of reflection-in-action and reflection-on-action typically found during everyday clinical practice. 'Gold standard' or 'textbook outcomes' are rarely, if ever, fully achieved in dental practice. Real-life clinical experiences offer challenges and opportunities for both teachers and students to engage with reflective learning processes. The materials generated allowed for an experience of individual reflective learning and the creation of a data bank or archive with potential use for the benefit of a wider student cohort. Various aspects of the students' views and comments on the process of reflection were reported and explored by means of a semi-structured focus group moderated by a linked educational advisor.

Acceptability of instructional videos

BACKGROUND

Over the past few decades, instructional videos have been incorporated as important tools in the dental classroom setting. This study aimed to investigate the acceptability of video demonstrations in comparison with live broadcasting and with the traditional face-to-face demonstrations in preclinical fixed prosthodontic classes.

METHODS

A group of dental students who have been exposed to three different methods of delivering practical demonstrations - face-to-face demonstrations, live broadcasting and recorded instructional videos - were included in the study. Preferences regarding these three methods were investigated using a questionnaire comprising a number of closed- and open-ended questions. Descriptive statistics were used to analyse the survey data using spss software. Survey comments were summarised and coded into categories.

RESULTS

A total of 163 questionnaires were distributed, and 145 responses were returned (a response rate of 89%). Ninety-two students (63%) considered the recorded video demonstrations to be the most convenient. Moreover, ninety-seven students (67%) found live demonstrations to be the least convenient. The majority of students either agreed (67 students) or strongly agreed (60 students) that watching the video before the session made it easier for them to perform the procedure in the lab.

CONCLUSION

Recorded instructional videos were the preferred method of delivering practical demonstrations for students in the preclinical courses of fixed prosthodontics. Instructors must focus on using the technological aids to increase their positive interaction with students. Instructional videos have been incorporated as important tools in the dental classroom setting.

Is Video Podcast Supplementation as a Learning Aid Beneficial to Dental Students?

INTRODUCTION

Podcasting has recently emerged as an important information technology tool for health professionals. Podcasts can be viewed online or downloaded to a user computer or a handheld multimedia device like a portable MP3 player, smart phone and tablet device. The principal advantage of the podcast is that the presentation of information need not be linked with any particular time or location. Since students are familiar with newer technology tools and may be using it on a regular basis, video podcast could serve as a convenient tool for students to help remember both conceptual and factual information.

AIM

The purpose of this study was to assess the attitude of first year dental students towards video podcast supplementation and to assess the efficacy of video podcast as a teaching aid in comparison to text book reading.

MATERIALS AND METHODS

First year dental students were recruited for this study. A didactic lecture class was conducted for the students (n=100). The students were then randomly divided into two groups. Students present in group A (n=46) underwent a video podcast session followed by a multiple choice question test. This was followed by student feedback to assess the usefulness of video podcast. Students belonging to group B (n=54) had a study session for 20 minutes followed by the MCQ test. Students then underwent the video podcast session followed by feedback to assess the utility of video podcast. Mann-Whitney U test was applied to compare the difference in the median MCQ score between the two groups.

RESULTS

The findings revealed a significant gain in the median MCQ score in the intervention group (group A) when compared to control group (Group B). In the feedback form, 89% of students agreed that the video podcast might be useful as it would enable them to view slides and hear the lectures repeatedly.

CONCLUSION

Students who underwent the video podcast session performed significantly better in the MCQ test compared to students who underwent text book reading alone. This demonstrates an advantage of video podcasts over text book reading. Majority of students accepted the benefits of video podcast supplementation.

Perceptions of D.M.D. student readiness for basic science courses in the United States: can online review modules help?

There can be a disconnect between the level of content covered in undergraduate coursework and the expectations of professional-level faculty of their incoming students. Some basic science faculty members may assume that students have a good knowledge base in the material and neglect to appropriately review, whilst others may spend too much class time reviewing basic material. It was hypothesised that the replacement of introductory didactic physiology lectures with interactive online modules could improve student preparedness prior to lectures. These modules would also allow faculty members to analyse incoming student abilities and save valuable face-to-face class time for alternative teaching strategies. Results indicated that the performance levels of incoming U.S. students were poor (57% average on a pre-test), and students often under-predicted their abilities (by 13% on average). Faculty expectations varied greatly between the different content areas and did not appear to correlate with the actual student performance. Three review modules were created which produced a statistically significant increase in post-test scores (46% increase, P < 0.0001, n = 114-115). The positive results of this study suggest a need to incorporate online review units in the basic science dental school courses and revise introductory material tailored to students' strengths and needs.

A comparison of two forms of teaching instruction: video vs. live lecture for education in clinical periodontology

INTRODUCTION

This crossover controlled study aimed to compare the knowledge and skill attained by third-year dental students in three clinical exercises in the discipline of periodontology through video and live lecture instruction.

METHODS

Students (n = 35) segregated into two group either viewed a video or attended a live lecture repeated over three clinical teaching sessions. Pre-test and post-test written assessments were completed and comparisons between video and live lecture done (analysis of variance, P < 0.05). Students were assessed on clinic by a simple checklist. A questionnaire was administered after all three sessions to determine preferences and opinions on video and live lecture.

RESULTS

For the combined three sessions, both video (n = 48) and live lecture (n = 47) groups attained similar mean pre-test scores. The mean post-test score was statistically significantly greater (P = 0.049) for the live lecture (74.9%, SD 14.9) compared to the video group (68.6%, SD 16.3). All students attained clinical proficiency via the simple checklist. In adding to their clinical skill, more students favoured video (97%) vs. live lecture (78.8%). Most students (97%) favoured a future combination of video and lecture.

DISCUSSION

While students were deemed clinically competent via a simple checklist, the live lecture group performed better than the video group via the in-depth post-test assessment. Students had a preference for video and would like it integrated in the lecture rather than act as a substitute for the lecture.

CONCLUSION

The use of video alone in clinical periodontology training may have limitations unless supplemented by appropriate learning activities.

Evaluation of the educational value of YouTube videos about physical examination of the cardiovascular and respiratory systems

BACKGROUND

A number of studies have evaluated the educational contents of videos on YouTube. However, little analysis has been done on videos about physical examination.

OBJECTIVE

This study aimed to analyze YouTube videos about physical examination of the cardiovascular and respiratory systems. It was hypothesized that the educational standards of videos on YouTube would vary significantly.

METHODS

During the period from November 2, 2011 to December 2, 2011, YouTube was searched by three assessors for videos covering the clinical examination of the cardiovascular and respiratory systems. For each video, the following information was collected: title, authors, duration, number of viewers, and total number of days on YouTube. Using criteria comprising content, technical authority, and pedagogy parameters, videos were rated independently by three assessors and grouped into educationally useful and non-useful videos.

RESULTS

A total of 1920 videos were screened. Only relevant videos covering the examination of adults in the English language were identified (n=56). Of these, 20 were found to be relevant to cardiovascular examinations and 36 to respiratory examinations. Further analysis revealed that 9 provided useful information on cardiovascular examinations and 7 on respiratory examinations: scoring mean 14.9 (SD 0.33) and mean 15.0 (SD 0.00), respectively. The other videos, 11 covering cardiovascular and 29 on respiratory examinations, were not useful educationally, scoring mean 11.1 (SD 1.08) and mean 11.2 (SD 1.29), respectively. The differences between these two categories were significant (P<.001 for both body systems). The concordance between the assessors on applying the criteria was 0.89, with a kappa score >.86.

CONCLUSIONS

A small number of videos about physical examination of the cardiovascular and respiratory systems were identified as educationally useful; these videos can be used by medical students for independent learning and by clinical teachers as learning resources. The scoring system utilized by this study is simple, easy to apply, and could be used by other researchers on similar topics.

Do educational methods affect students' ability to remove artificial carious dentine? A randomised controlled trial

This trial aimed to evaluate the influence of two educational methods on students' ability to remove artificial carious dentine. Traditional lecture and lecture plus a live demonstration of artificial carious tissue removal were compared in a blind two-parallel-group design. Twenty-six students were randomly divided into two groups, and their skills were evaluated according to the following criteria: time spent on the dentine excavation procedure (in min), students' perceived confidence in conducting the procedure (graded assessed on a scale from 0 to 10), and the outcome of artificial carious tissue removal, evaluated by measuring the residual dyed artificial carious dentine layer (in μm). Statistical analyses were carried out using a t-test to compare the students' confidence and time spent on the procedure, and a two-way ANOVA was used to compare residual artificial decayed dentine with educational methods and tooth region (incisal, medium, and cervical thirds) as factors. There were no differences between the methods regarding excavation time (P = 0.898) and students' confidence (P = 0.382). The residual artificial carious dentine results showed that the educational method (P < 0.001) and cavity region (P < 0.001) were statistically significant, as was their interaction (P = 0.040). The lecture plus live demonstration group presented the best results for artificial caries removal. Although there were no differences between the two groups for the cervical region, the best results for the lecture plus live demonstration group was in the other two-thirds of the tooth.
