An innovative educational approach in using instructional videos to teach dental local anaesthetic skills

How to design effective educational videos for teaching evidence-based medicine to undergraduate learners - systematic review with complementing qualitative research to develop a practicable guide

BACKGROUND

eLearning can be an effective tool to achieve learning objectives. It facilitates asynchronous distance learning, increasing flexibility for learners and instructors. In this context, the high educational value of videos provides an invaluable primary component for longitudinal digital curricula, especially for maintaining knowledge on otherwise rarely taught subjects. Although literature concerning eLearning evaluation exists, research comprehensively describing how to design effective educational videos is lacking. In particular, studies on the requirements and design goals of educational videos need to be complemented by qualitative research using grounded theory methodology.

METHODS

Due to the paucity of randomized controlled trials in this area, there is an urgent need to generate recommendations based on a broader fundament than a literature search alone. Thus, the authors have employed grounded theory as a guiding framework, augmented by Mayring's qualitative content analysis and commonly used standards. An adaptive approach was conducted based on a literature search and qualitative semi-structured interviews. Drawing on these results, the authors elaborated a guide for creating effective educational videos.

RESULTS

The authors identified 40 effective or presumedly effective factors fostering the success of video-based eLearning in teaching evidence-based medicine, providing a ready-to-use checklist. The information collected via the interviews supported and enriched much of the advice found in the literature.

DISCUSSION

To the authors' knowledge, this type of comprehensive guide for video-based eLearning needs has not previously been published. The interviews considerably contributed to the results. Due to the grounded theory-based approach, in particular, consensus was achieved without the presence of a formal expert panel. Although the guide was created with a focus on teaching evidence-based medicine, due to the general study selection process and research approach, the recommendations are applicable to a wide range of subjects in medical education where the teaching aim is to impart conceptual knowledge.

Effectiveness of a flipped classroom for undergraduate in implant dentistry hands-on course

PURPOSE

The purpose of this study was to compare the learning in the implant dentistry hands-on course to that of the flipped classroom (FC) and the traditional lecture cohorts (control).

MATERIALS AND METHODS

In this study,80 students were enrolled for the first time in an implant dentistry program. Subsequently, they were divided into two groups. The first, the FC group, which had free access to a video with a PowerPoint presentation on the Chaoxing-WHU-MOOC platform about the implant placement on first molar sites before class. The second, the control group, which attended a didactic lecture describing implant practice on the first molar site via a bidirectional multimedia interactive teaching demonstration and then operated on a simulation model. Cone beam computed tomography (CBCT) and the deviation gauge were utilized to analyze the accuracy of the implant placement in the students' models. An online satisfaction questionnaire was distributed to both groups one week after the class.

RESULTS

The linear deviation of the CBCT examination did not show any statistical difference between the two groups concerning cervical, apex, and angular. A significant buccal deviation was observed in the control group compared with the FC group (mean: 0.7436 mm vs. 0.2875 mm, p = 0.0035), according to the restoration-level deviation gauge. A total of 74.36% of students in the FC group placed implant within 0.5 mm buccal-to-lingual deviations, but only 41.03% of students in the control group reached within 0.5 mm buccal-to-lingual deviation ranges. Additionally, 91.67% of the students in the FC group and 97.5% of the students in the control group were satisfied with the practical implant class.

CONCLUSION

FC was more effective than a didactic lecture for implant dentistry practical skill acquisition.

Dental students' perceptions and educational impact of preclinical interactive videos compared and in combination with live demonstrations

OBJECTIVE

To study the utility of simulation videos with embedded quiz items compared and in combination with live hands-on demonstrations of dental procedures.

METHODS

Thirty-three videos with embedded items were developed to help students understand the procedures they had to practice in the simulation laboratory. Videos were uploaded to the university LMS platform for students to watch and complete the embedded items as many times as they liked. All 76 students from 2021 and 73 from 2022 Integrated Dentistry III courses were invited to participate in the study. Practical (OSCE) and theoretical (MCQ) exam grades of the 2021 academic year, when interactive videos replaced live demonstrations, were collected and compared to those of the previous years (2017-2020) when only live demonstrations were performed, as were those from the 2022 academic year, when videos were complemented with hands-on live demonstrations. At the end of each year, a perception questionnaire was voluntarily completed by the students.

RESULTS

Assessment grades were significantly higher in the 2021 academic year when interactive videos were incorporated versus the 2017-2020 period when only live demonstrations were performed. However, the combination of interactive videos with live demonstrations performed during 2022 showed the highest exam grades. Seventy-nine percent of students answered the questionnaire, highly valued the utility of the interactive videos and liked the embedded items. Overall, they stated that they learned from the videos.

CONCLUSIONS

Interactive videos of preclinical procedures with embedded items combined with live demonstrations can significantly enhance students' learning and are valued by students.

Online short videos promoting public breast cancer literacy: a pretest-posttest control group trial on efficiency, attitude, and influencing factors

Background

Short videos on social media are playing an increasingly important role in cancer health education today. It is important to explore how the actual communication effect of health videos and the knowledge absorption of users are influenced by different factors of the video creation process.

Objective

The objective of our study is to access the factors influencing breast cancer health education through short videos on efficiency and quality.

Methods

Three pairs of videos about breast health were created and participants completed questionnaires before and after watching the videos. A paired t-test was used to analyze within-group change scores. RM-ANOVA was used to assess the relationship between the pretest, posttest, and three variables.

Results

Watching short videos can significantly increase viewers' knowledge of related health topics (p < 0.05). The viewers' concentration level while watching was significantly higher for the video with background music (BGM) than for the video without BGM (p = 0.006). The viewers' willingness to share was significantly higher for the video with a progress bar than for the video without a progress bar (p = 0.02). Using an interpreter wearing a doctor's uniform instead of casual wear and setting a progress bar can significantly improve the efficiency of knowledge absorption (p < 0.05).

Conclusion

A uniformed interpreter, BGM and a progress bar are factors influencing the efficiency of short health videos. They can be applied in video making to explore better ways of promoting cancer health education in the new mobile Internet environment.

Edpuzzle versus Moodle: Learning Tools in Pediatric Dentistry Practice: A Study Pilot

The aim of the present study was to compare the results of two educational platforms for the development of Flipped Learning (FL) in the preclinical practices of paediatric dentistry: Edpuzzle and Moodle 3.4. Methods: Fifty students filled out a questionnaire on knowledge of pulp treatments in primary dentition (Pre-Q). They were divided into two groups: one watched a video on the pulpotomy technique before preclinical practice using Moodle 3.4 (group A) and the other used Edpuzzle (group B). On the day of practice, the students resolved any doubts with the teacher. Next, they performed a pulpotomy on an artificial tooth and answered the questionnaire again (Post-Q) together with a satisfaction survey. Results: In both groups, an increase in the number of correct answers was found in the Post-Q compared to the Pre-Q (p < 0.001), but with no significant differences between groups. The pulpotomy practice ratings were higher in group B, which used Edpuzzle (p < 0.001). In the satisfaction survey, we only found significant differences (p = 0.003) in access to the video, since 100% of the students in group A found it easy to view it through Moodle, unlike in group B. Conclusions: Our results suggest that the use of educational platforms specially designed for FL, such as Edpuzzle, can improve the qualifications of students in paediatric dentistry practices.

Insight on the influence of technology-enhanced learning in orthodontics' education: A systematic review

OBJECTIVES

Technology-enhanced learning (TEL) provides a pliable and current way to present orthodontic curriculum material to students. This review aimed to assess the effectiveness of TEL compared with traditional learning methods in the field of orthodontics.

MATERIALS AND METHODS

The search comprised randomised controlled trials (RCTs) related to orthodontics' interactive learning from the following databases: PubMed, Scopus, CENTRAL, Psyclnfo, ERIC, Web of Science, Dissertations and Theses Global. Two authors performed the screening, data extraction and assessed risk of bias using the Cochrane tool (Rob 2) blindly and in duplicate. Kirkpatrick's 4-level evaluation model was used to evaluate educational outcomes.

RESULTS

A total of 3131 records were identified of which 11 RCT were included. On level 1 (Reaction), students had a positive attitude towards TEL. On level 2 (Learning), included studies did not report any significant knowledge improvement when TEL was compared with traditional learning strategies. One study assessed level 3 (Behaviour), where students felt that flipped classroom learning created feelings of greater confidence. On level 4 (Results), most studies suggested that TEL tools are as equally effective in imparting information as traditional tools and recommended that both methods should be considered in teaching students.

CONCLUSION

Technology-enhanced learning techniques might have the potential to enhance educational outcomes in orthodontic education and students seem to enjoy the implementation of technology in the learning process. These educational tools should be used as an adjunct to the traditional didactic classroom, and not as a replacement, due to the challenges encountered with their application.

A homemade simulation model improves the impact of e-learning for the practical administration of dental anaesthesia

INTRODUCTION

A simulation model improves the learning of dental anaesthesia in dental students. This study explored first, the making at home of a dental anaesthesia simulation model by dental students, and second, the impact of that simulation model on the learning of dental students following an online course. We compared the level of knowledge, the level of perception of confidence to perform the basic injection technique (BIT) of dental anaesthesia, and the level of attitude towards e-learning of the BIT between a group of dental students who had an online course with a home-made dental anaesthesia simulation model (HMDASM) and a group of dental students who did not use that model.

MATERIALS AND METHODS

A group of participants (n = 28) used the HMDASM to learn the BIT with an e-learning course. Another group of participants (n = 28) followed the same e-learning course, but that group used a lemon to practise the BIT. The two groups answered questionnaires that explored the level of theoretical knowledge on the BIT, the level of perception of confidence to perform the BIT, and the level of attitude towards e-learning of the BIT. Questionnaire scores from each group were compared by a Student's t-test (p ≤ .05).

RESULTS

The group that used the HMDASM had a level of knowledge similar to that of the other group (p > .05). The group that used the HMDASM had a level of perception of confidence to perform the BIT and a level of attitude towards online learning of the BIT higher than those of the group that did not use the simulation model (p < .05).

CONCLUSION

The use of a HMDASM had a positive effect on dental students following an online course to learn the BIT.

Dental Student’s Satisfaction with the Video-assisted Educational Approach in Teaching Oral and Maxillofacial Surgery Principles

BACKGROUND: Educating dental students in practical skills are a difficult task that has become increasingly demanding since the outbreak of COVID-19. Today, the use of digital media plays an essential role in teaching practical skills. AIM: This study investigated the effect of educational videos on oral and maxillofacial surgery basics on dental student’s satisfaction. METHODS: Six subjects were chosen from the principles of oral and maxillofacial surgery, and according to the necessary standards, educational videos were made based on the needs assessment of students. Fellow attending evaluated and approved each video. Students were shown videos in six 2-h sessions. Students were given a researcher-created questionnaire with proven validity and reliability. Students filled out questionnaires to evaluate the impact of educational videos as well as the structure of educational videos. RESULTS: Two hundred and three students participated in this study in their 4th−6th years. In this study, 203 students in their 4th to the 6th year participated. Most students were satisfied with the structure of educational videos (73.9%); in general, 84.7% of students expressed their satisfaction with this method. Half of the students preferred video training over face-to-face training in oral and maxillofacial surgery (50.4%). Many students suggested that these videos be included in the curriculum (80.7%). CONCLUSION: Students’ overall satisfaction with the structure and impact of educational videos indicates that educational videos made and evaluated by dental professors can help teach practical topics as a part of the curriculum.

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.

Learning of paediatric dentistry with the flipped classroom model

INTRODUCTION

The flipped classroom (FC) is a pedagogical model that can be very useful in obtaining a dentistry degree. The main objective of this study was to compare learning between student groups introducing FC in the area of paediatric dentistry at the Complutense University of Madrid in 2019.

MATERIALS AND METHODS

In this study, 76 students enrolled for the first time in the Pediatric Dentistry programme and completed a questionnaire (pre-Q) regarding specific theoretical knowledge about pulpotomies. Subsequently, they were divided into two groups: group A, which had free access before the class to an explanatory video about the indications and techniques of pulpotomy and group B, which viewed the same video only one time in class. After that, all students completed the same questionnaire (post-Q) again and a survey on the degree of satisfaction about the teaching method.

RESULTS

The differences in score between the post-Q and pre-Q in group A had a mean (SD) value of 3.5 (2.4) and in group B, a mean (SD) of 2.5 (2.2), with a p value of .07. In questions 3, 5 and 8, learning was greater in the experimental group (p = .007, p = .02 and p = .001, respectively). For 74.4% of the students in group A, accessing the video previous to the class was a very useful tool.

CONCLUSIONS

These results suggest that implementing FC in paediatric dentistry classes help students to acquire more theoretical knowledge, which is necessary before practical teaching.

Enhancement of Skill Competencies in Operative Dentistry Using Procedure-Specific Educational Videos (E-Learning Tools) Post-COVID-19 Era-A Randomized Controlled Trial

E-learning has completely transformed how people teach and learn, particularly in the last three pandemic years. This study evaluated the effectiveness of additional procedure-specific video demonstrations through E-learning in improving the knowledge and practical preclinical skills acquisition of undergraduate dental students in comparison with live demonstration only. A randomized controlled trial was conducted for the second-year dental students in the College of Dentistry, Jouf University, to evaluate the impact of E-learning-assisted videos on preclinical skill competency levels in operative dentistry. After a brief introduction to this study, the second-year male and female students voluntarily participated in the survey through an official college email. Fifty participants were enrolled in the study after obtaining informed consent. The participants were randomly divided into two groups, twenty-five each. The control group (Group A) was taught using traditional methods, and the intervention group (Group B) used E-learning-assisted educational videos and traditional techniques. An objective structured practical examination (OSPE) was used to assess both groups. The faculty members prepared a structured, standardized form to evaluate students. After OSPE, statistical analysis was done to compare the grades of OSPE between Group A and Group B. Logistic regression analysis was done to express the effect of components of the OSPE on gender, cumulative gross point average (CGPA), Group A and Group B. The results showed a significant difference in the experimental groups after the intervention (p < 0.000). The simulator position parameter demonstrated that the participants had a significant competence level after the intervention by procedure-specific videos (p < 0.000) and an exponential value of 6.494. The participants taught by E-learning-assisted procedure-specific videos and traditional teaching strategies demonstrated an enhanced learning and skill competency level than participants who used only traditional teaching strategies.

Epidural Catheterization in Obstetrics: A Checklist-Based Video Assessment of Free Available Video Material

Epidural catheterization has become an indispensable part of modern pain therapy, for example, in obstetrics. Learning how to master this skill is an important competency. Videos are among the information sources with the highest information content for learning such skills. The present study aims to analyze videos regarding epidural catheter placement provided on the YouTube platform based on a validated checklist. An expert workshop selected crucial items for learning epidural catheterization in obstetrics. Items were identified and optimized in a five-step testing process. Using this checklist, videos from YouTube were evaluated by eleven health care professionals. Sixteen videos were identified and analyzed. Concerning the catheterization-specific part of the checklist, only two videos showed satisfactory quality. In the didactic part, eleven out of 21 items reached a mean score >50% of the points. Regarding interrater reliability, the catheterization-specific checklist was shown to be substantial (Fleiss’ kappa = 0.610), and the didactic part was shown to be fair (Fleiss’ kappa = 0.401). Overall, standard monitoring and appropriate aseptic technique were followed in only 42% and 49% for the procedure. There was a significant correlation between the runtime and the content quality (p < 0.001). No correlation could be found in terms of platform rating parameters. The video quality varied highly in terms of the requirements of this practical skill. The majority appear unsuitable for self-study due to serious errors and deficiencies regarding patient safety. However, there is no quality control on free platforms. Accordingly, it is difficult to identify suitable videos for educational purposes.

Digital anatomy table in teaching-learning process of the temporomandibular joint anatomy

INTRODUCTION

The use of teaching resources and digital objects has gradually been incorporated into dental schools. This study aimed to evaluate the digital anatomy table in teaching-learning process of the temporomandibular joint (TMJ) anatomy and the student's perception regarding this resource.

MATERIALS AND METHODS

A cross-sectional study was conducted on 41 undergraduate dental students. Knowledge assessment tests were applied at different time intervals: before and after the TMJ theoretical class, after the practical class on prosected specimens and after the use of digital anatomy table. The medians of the scores obtained in the three groups (theoretical class, practical class and digital table) were descriptively analysed and submitted to Wilcoxon, Kruskal-Wallis and Student-Newman-Keuls statistical tests. The perception survey was conducted at the end of the study.

RESULTS

When the teaching strategies were compared amongst each other, the medians of the scores with the digital anatomy table were significantly higher than after the theoretical and practical classes. At the end of the research, there were no differences amongst the three groups (theoretical class, practical class and digital table). Regarding the perception, the majority of the students reported that the digital anatomy table helped them to understand the content of the theoretical class.

CONCLUSION

It was concluded that learning with the use of the digital anatomy table did not increase the knowledge of dental students with respect to the TMJ anatomy. The students' perceptions of the digital anatomy table were positive and that it could be used as an additional resource in the teaching-learning process.

Nursing Students Perceptions of Using YouTube to Teach Psychomotor Skills: A Comparative Pilot Study

Introduction

Current techniques to teach psychomotor skills to nursing students involve the traditional modeled performance by an instructor followed by rote memorization and practice. This outdated model presents many issues including no reference to refer back to, lacks technology integration, and only meets a few learning styles. A developmental study utilizing the social media platform YouTube was examined to gain student’s perspective on this as a teaching tool to assist in skill acquisition.

Objective

Do nursing students, who are enrolled in a Bachelor of Science Nursing (BSN) program and who are taught psychomotor nursing skills via demonstration on the social media platform YouTube, prefer this technology to traditional demonstration, and to evaluate their overall perceptions of YouTube?

Methods

Data collection was done utilizing a nursing cohort enrolled in a BSN program. Participants were split into two groups. The control group was taught intravenous (IV) skills in the traditional teacher demonstration followed by practice. Experimental group was given access to a YouTube video series consisting of the identified IV skills. After testing for competency was concluded, control group was given access to the videos. A questionnaire was developed and sent out for evaluation.

Results

Participants reported that their preferred learning style when learning new nursing skills was visual (41.7%) followed by a combination of visual, tactile, and auditory (41.7%). All respondents (100%) reported YouTube videos increased their learning. Respondents (100%) also noted that having access to the videos better prepared them. In experimental group, all participants (100%) watched the videos, and in the control group, only (16.7%) of students watched the videos after the skill had been learned.

Conclusion

Results demonstrated that students prefer YouTube videos when learning new skills. They reported feeling better prepared to learn. YouTube is a potential way to increase skill acquisition and integrate technology into the nursing curriculum.

A flipped classroom, same-level peer-assisted learning approach to clinical skill teaching for medical students

Background

Clinical procedural skills are vital components of medical education. Increased student intake and limited capacity of medical schools necessitate more efficient ways to deliver clinical skill teaching. This study employed a flipped classroom, peer-assisted learning approach to deliver clinical skill teaching. It aimed to determine the influence of pre-class demonstration video watching and in-class student-student interactions on clinical skill acquisition.

Methods

In 2017, a cohort of 205 medical students in their penultimate year of undergraduate medical study were recruited, and they learned bag mask ventilation and intravenous cannulation during this study. The participants watched a demonstration video before class, and then underwent self-directed practice as triads. Afterwards, each participant video-recorded their skill performance and completed post-class questionnaires. The videos were evaluated by two blinded assessors.

Results

A hundred and thirty-one participants (63.9%) completed the questionnaire. For bag mask ventilation, participants who claimed to have watched the corresponding demonstration video before class achieved higher performance scores (those who watched before class: 7.8 ± 1.0; those who did not: 6.3 ± 1.7; p < 0.01). For intravenous cannulation, while there is no significant difference in performance scores (those who watched before class: 14.3 ± 1.3; those who did not: 14.1 ± 1.4; p = 0.295), those who watched the video before class received less interventions from their peers during triad practice (those who watched before class: 2.9 ± 1.8; those who did not: 4.3 ± 2.9; p < 0.05). The questionnaire results showed that most participants preferred the new approach of clinical skill teaching and perceived it to be useful for skill acquisition.

Conclusion

The flipped classroom, same-level peer-assisted learning model is potentially an effective way to address the current challenges and improve the efficiency of clinical procedural skill teaching in medical schools.

A comparison of video-based and slide-based teaching before hands-on rubber dam application: A quantitative and qualitative study

PURPOSE/OBJECTIVES

Instructional videos may demonstrate the execution of complex clinical procedures and the cooperation between members of the dental team better than traditional slide-based teaching materials. The aim of the present study was to compare the effect of a procedural video on student ratings to a traditional still-image-based presentation in a course on rubber dam application.

METHODS

In a randomized, double-blind, parallel arm design, participants (46 dental students) completed a seven-item, five-step Likert-scale questionnaire at baseline (t1), after a video-based or slide-based demonstration of rubber dam application (t2) and after hands-on training (t3). The students' judgement on the benefits of rubber dam (items 1-3), their motivation to use rubber dam (item 4), their self-efficacy (items 5-6) and their expected use of the teaching material (item 7) were assessed. Changes in the students' individual answers were analyzed for each item and comparison between intervention groups made. Moreover, the impact of the teaching format on in-class discussions was analyzed qualitatively using a thematic approach RESULTS: Both interventions arose comparable significant improvement in the students' Likert-scale ratings from t1 to t2, and again from t2 to t3. No significant differences between intervention groups were found in the students' ratings or in the qualitative analysis.

CONCLUSIONS

Procedural videos have proven to be a valuable learning aid in a variety of teaching formats, but in the context of a live lecture, they may not constitute an improvement over traditional text- and still-image-based presentations.

[Development and validation of a checklist for evaluating videos for learning resuscitation measures]

BACKGROUND

Well-performed resuscitation measures can improve the outcome in the event of cardiovascular arrest. Medical students often use teaching videos to learn practical skills. Studies confirmed the often inadequate quality of the videos on resuscitation available on the Internet. An evaluation using a validated checklist based on the current guidelines has so far been lacking.

OBJECTIVE

The development and validation of a checklist for evaluating instructional videos on resuscitation.

MATERIAL AND METHODS

In an expert workshop, checklist items were formulated based on the current guidelines. The checklist was tested by emergency physicians in a 4-step review process. The evaluations were analyzed and the items adjusted and specified if necessary. After the review process was completed, the checklist was applied to 74 videos on the topic of resuscitation.

RESULTS

The checklist consists of 25 items in 4 categories (initial measures, chest compression, AED use, breathing), which are rated on a 3-level Likert scale. A total of 16 emergency doctors participated in the study and rated an average of 9.3 ± 5.7 videos each. The reviewers agreed in 65.1 ± 12.6% of the cases. The highest agreement was achieved in the subtopic AED, with the item "do not touch patients in shock" having the highest agreement. The items in the thoracic compression category were most often rated differently.

CONCLUSION

For the first time, a checklist for evaluating instructional videos for resuscitation was created and validated for German-speaking countries.

Impact of the DC/TMD instructional video on the practical skills of undergraduate students-A single-blinded, randomized controlled trial

INTRODUCTION

Competencies in the clinical examination of patients with temporomandibular disorders (TMD) can be achieved by self-instruction. This study aimed to identify the impact of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) instructional video on the practical examination skills of undergraduate students.

MATERIALS AND METHODS

One week prior to completing an objective structured clinical examination (OSCE) addressing the examination of patients with TMD, undergraduate students in their third year received either the DC/TMD manual (control group) or additionally watched the instructional video once (intervention group). After passing the OSCE, a feedback questionnaire was completed by the students.

RESULT

Fifty undergraduates were recruited to take part in the OSCE prior to their first clinical course. The sum scores achieved in the stations were higher in the intervention group, but missed significance. Participants of the intervention group more often agreed that completing the OSCE stations was easy, which was significant for one station (P = .023). 95.8% of the participating students supported the implementation of the video in dental education.

DISCUSSION

Due to the conception of the study, the video was only presented once to ensure that the control group had no access to the medium at all. However, it might be interesting to investigate whether repeated watching of the video enhances its effect.

CONCLUSIONS

Clinical competencies in the examination of TMD patients can be achieved by self-instruction with the DC/TMD manual and instructional video. Watching the video for educational purposes was highly recommended by undergraduate students.

Pedagogical development in local anaesthetic training in paediatric dentistry using virtual reality simulator

PURPOSE

With the advancements in technology, dental pedagogy has also evolved, and new learning technologies have emerged. Virtual reality (VR) as an education tool in dentistry is underutilised. VR as an adjunct in local anaesthesia (LA) teaching in paediatric dentistry has not been investigated. The study aimed to investigate dental student's perception of dental LA VR simulation on a paediatric patient and to determine whether this can improve students learning experience.

METHODS

Seventy-one students participated in a self-administered questionnaire before and after the use of dental LA VR simulator. Descriptive analysis was performed to determine the perceptions of experience gained through VR. The data were tabulated, graphed, and analysed using SPSS and GraphPad Prism software.

RESULTS

The study noted that 89.9% of participants perceived that it would improve their LA skills. After using dental LA VR, 83.1% of participants experienced more engaged in the learning activity, and 55.0% of participants agreed/strongly agreed that it improved their understanding of anatomical landmarks. Around 56.4% of participants agreed/strongly agreed that it added value compared with traditional LA teaching methods.

CONCLUSION

It can be concluded that the use of VR simulation can enhance students engagement and learning experience in paediatric dentistry settings and can be used as an additional means of LA training.

Effectiveness of Using an Instructional Video in Teaching Light-Curing Technique

PURPOSE

To investigate dental students' ability to deliver satisfactory amounts of irradiance and radiant exposure to simulated cavities by teaching the light-curing technique using instructional video compared to verbal instructions.

METHODS

Students attended the didactic light-curing lecture explaining the light-curing technique. Participants were divided into two groups (n=60). Each participant light-cured a class III and a class I simulated cavities with sensors built-in a Managing Accurate Resin Curing-Patient Simulator (MARC-PS) system, using a multiple-emission-peak light-emitting-diode unit. Each student either 1) watched an instructional video (V) showing the light-curing technique, or 2) received individual verbal instruction (I). The light-curing performance, in terms of the mean irradiance and radiant exposure, was recorded. Each student performed light-curing again on the simulated cavities. Students' feedback for the corresponding teaching method was collected. Comparisons between before and after each instructional method were analyzed using the Wilcoxon signed-rank test. Comparisons between both instructional methods were analyzed using a Mann-Whitney U-test (α=0.05).

RESULTS

The students' light-curing performance improved after both methods, as observed on the MARC-PS laptop monitor. The mean irradiance values were anterior-V=1280.6 (183.2), anterior-I=1318.0 (143.5), posterior-V=1337.5 (181.1), posterior-I=1317.6 (248.2) mW/cm². The mean radiant exposure values were for anterior-V=13.5 (2.7), anterior-I=13.3 (1.6), posterior-V=13.7 (1.9), posterior-I=13.7 (2.5) J/cm². No significant difference was found between both instruction methods. Students reported that each method was effective.

CONCLUSION

Using V was comparable to I and an effective tool for teaching the light-curing technique per the students' ability to deliver sufficient amounts of irradiance and radiant exposure to simulated cavities.

Effectiveness of technology-enhanced learning to improve periodontics educational outcomes: A systematic review

OBJECTIVES

Technology-enhanced learning (TEL) has been suggested as a suitable learner-centered pedagogical approach in dental education. However, the results of TEL effectiveness in periodontics education are controversial. Therefore, this systematic review aimed to evaluate the effectiveness of TEL to improve educational outcomes in the periodontics field compared to traditional learning methods.

METHODS

The search comprised randomized controlled trials (RCTs) and crossover studies that were related to periodontics education from the following databases: MedLine, PsycINFO, Eric, Scopus, EMBASE, and Web of Science. Two authors independently performed study selection, data extraction, and assessed risk of bias. Kirkpatrick's 4-level evaluation model was used to evaluate educational outcomes.

RESULTS

From 1642 studies, after applying inclusion criteria, 7 studies remained for analysis. On level 1 (Reaction), undergraduate dental students reported positive attitudes related to TEL. On level 2 (Learning), 3 studies found that TEL improved knowledge gain compared to traditional learning methods. Three other studies did not show any difference between TEL and conventional learning methods, and one found that traditional learning methods presented superior results. On level 3 (Behavior), 1 study found that TEL application improved students' performance. On level 4 (Results), 5 studies suggested that the implementation of TEL would improve educational outcomes in periodontics education if combined with traditional learning methods.

CONCLUSION

The findings showed that the exclusive use of TEL does not significantly improve periodontics educational outcomes when compared to traditional learning methods. However, the combination of TEL and traditional learning methods can be the key to enhancing periodontics education.

A Tale of Two Teaching Methods: Students' Clinical Perspectives on Administering Dental Local Anesthetics

Various preclinical methodologies have been adopted by dental and oral health programs to develop student competence in administering dental local anesthetics (LA). Student-to-student practice is the most common preclinical training method. However, manikin simulation models have been introduced to avoid possible complications and ethical concerns with student-to-student injections. In 2017, the methodology was changed in the Bachelor of Oral Health program at The University of Sydney School of Dentistry in Australia from student-to-student practice to manikin simulation models. The aim of this study was to compare the students' learning experience, perceived confidence, and anxiety in giving their first injections to patients in these two preclinical training methods. A mixed-methods cohort design was used to compare the 2016 (n = 42) and 2017 (n = 32) oral health students' experiences and perceptions and evaluate students' clinical experience after commencing LA practice on patients. Students completed a questionnaire about their perceived level of confidence and anxiety before and after their first LA to a child and an adult for both infiltration and inferior alveolar nerve b lock (IANB) injections. Focus groups were conducted to further investigate the students' experience. The results showed that the perceived confidence and anxiety of the two cohorts did not differ significantly from each other. Although students found it difficult to transition into clinical practice without having experienced LA themselves, the manikin simulation practice provided a safe learning platform that avoided ethical and legal concerns. These findings support the use of manikin simulation models as an alte rnative method for dental local anesthetic preclinical training.

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.
