Global disruptions caused by coronavirus disease 2019 (COVID-19) affects all walks of life, and dentistry and dental education are no exceptions. Dental education uniquely blends didactic courses and hands-on clinical training seamlessly to prepare oral healthcare providers of the future. Apart from economical and access to care implications, closure of all the dental institutions in the United States affects their educational mission greatly, equally disturbing pre-doctoral and graduate training. Efforts are ongoing to continue the educational mission in dental institutions by delivering scheduled course content remotely using multiple online tools. In spite of those efforts, since clinical experiences cannot be completely replaced by any available alternative method of instruction that is 1270

Increasing importance is attached to teaching generic skills to undergraduate students in various disciplines. This article describes an extracurricular, student-led activity for teaching generic skills using the Model United Nations over three months. The activity used the Health Care Simulation Model (HCSM) with peer learning and role-playing to accomplish its objectives. An interview was used to select from undergraduate and postgraduate dental students at Alexandria University, Alexandria, Egypt, to develop a group of staff to act as peer teachers after receiving training (n=77). These peer teachers provided training for 123 undergraduate dental students to serve as delegates who acted as trainees or peer learners. At the end of the training sessions, a conference was held in which the students played the roles of delegates representing oficials responsible for health care systems in ten countries. The students reported improvement in generic skills, enjoyed several aspects of the experience, and disliked other aspects of the model to a lesser extent. In multivariate analysis, perceived usefulness of the HCSM was signiicantly greater for staff than delegates and increased as self-reported improvement in knowledge of health care systems increased. This study suggests that innovative, student-centered educational methods can be effective for teaching generic skills and factual information.

Purpose To compare the use of virtual 3D casts as an alternative to paper‐based exercises in preclinical removable partial denture (RPD) design in terms of student outcomes (as evidenced by exercise evaluation scores), as well as student attitudes related to the 2 formats. The first hypothesis of this study is that virtual 3D digital models in the exercise will result in better student outcomes as evidenced by the final exercise score compared to the 2D drawings. The second hypothesis is that virtual 3D digital models in the exercise will result in greater student acceptance compared to the 2D drawings. Materials and Methods Students were divided into 2 equal, randomly assigned groups Both groups were made to solve 2 exercises: a class II exercise and a class IV exercise. Group 1 received the first exercise (exercise #1) as a Kennedy class IV design exercise in virtual 3D and the second exercise (exercise #2) as a Kennedy class II design exercise in traditional format. Group 2 would receive the opposite exercise #1 as a Kennedy class IV in traditional format and exercise #2 as a Kennedy class II in virtual 3D format. Virtual 3D casts were made to be identical to the traditional exercises. Students were then asked to complete a short survey to assess their preferences. The Wilcoxon Rank Sum test was used to compare the distribution of scores of exercises using the virtual 3D format with the scores when students used the traditional 2D format. Preference comparisons for the 2 formats were accomplished using exact binomial tests. Results There was no difference in learning outcomes based on the distribution of student scores for either exercise independent of presentation format (p > 0.52). There was also no difference in individual student score between 2 identical exercises, independent of whether the exercise was using 3D virtual models or 2D drawings. A greater proportion of students agreed with the statements that favored the use of the virtual 3D models than disagreed with respect to all 7 questions asked, based upon the sign test (comparing agreement vs. disagreement with the statement, p < 0.0003 in all instances). Conclusion Despite there being no difference in learning outcomes (final scores), the students showed an overwhelming preference in having the virtual 3D casts part as part of the curriculum.

When educating dental students or prosthodontic residents, a picture can be worth a thousand words. If that is so, then what could enhanced 3D modeling be worth relative to enhancing student learning? The answer is undoubtedly more than what a picture can provide. That is why the use of 3D models has become increasingly common with respect to patient care. The 3D modeling allows the patient to visualize more clearly the proposed treatments and outcomes; however, while 3D modeling has started to make an appearance in dental education, many of the current 3D modeling techniques do not offer the flexibility needed for dental education and enhanced student learning. At the University of Iowa, the use of 3D modeling software has enabled the creation of 3D models that can be altered or customized to be used in a more flexible way to teach students in the arts and complexities of removable partial denture (RPD) design and associated components. This educational technique article will: (1) demonstrate how these 3D models can be used to enhance student perception and learning regarding RPDs; and (2) will demonstrate using videos and web‐based portals to show how the 3D RPD models were created and then used for educational purposes.

In order to provide restorations and dental prostheses that are esthetically pleasing, functional and in harmony with a patient's occlusion, practitioners must have a thorough knowledge of dental anatomy. Recent studies have shown that virtual three‐dimensional (3D) models greatly enhance educational outcomes in dental anatomy courses. This article describes a novel educational technique and uses videos and web‐based portals to demonstrate how to create a virtual 3D tooth model from a scan of a natural tooth for use in dental anatomy courses.

Critical thinking is ubiquitous in patient care. One track for critical thinking develops skillsets emulating the thought process of the master clinician using probing questions and has been offered in treatment planning, literature search, and critique, risk assessment in caries and geriatrics, technology decision‐making, EBD, and IPP. This paper offers 2 additional critical thinking skillsets following this emulation model in social work and ethics. Conceptualization, another form of critical thinking, is also ubiquitous in health care, yet almost no literature exists to guide learning and assess performance on conceptualization. This paper introduces for discussion 2 examples of conceptualization—“How and how much does this situation differ from the ideal?” and “How does the student/practitioner conceptualize the outcome prior to the imminent procedure?” —used continually by the practitioner in patient care situations. The result is 4 additional critical thinking skillsets at different stages of development in the armamentarium for the teacher.

Purpose/Objectives To assess student perceptions on learning dental anatomy using natural extracted teeth, 3D printed models, 3D virtual models, and augmented reality (AR) technology.  Methods Eighty first‐year dental students enrolled in the dental anatomy course were instructed to examine four stations. The stations included four versions of a mandibular first molar: an extracted natural tooth, a 3D printed model, a 3D virtual model, and a model displayed on a novel AR device. After examining all stations, the students were asked to complete an electronic survey. Bivariate analysis was performed to determine whether students’ perceptions are related to their demographic characteristics and technological experience with computer use, 3D modeling, and video games.  Results Seventy students completed the survey (87.5% response rate). Students rated natural teeth to have the highest educational value, the 3D printed tooth to be the most accessible, and the AR application to be the most interesting modality. Students who played little to no video games were more likely to rate AR as high educational value (48.8% vs. 10.3%; p < 0.001), while students with little 3D modeling experience were more likely to rate high accessibility of the 3D Model (78.1% vs. 48.3%; p < 0.001). No statistically significant associations between the perceptions and students’ demographic characteristics or use of computer were noted. Conclusion The natural extracted tooth was rated highest in educational value, while the 3D printed model was rated easiest to use, and the AR model was the most interesting to the students.

The purpose of this study is to assess students' perception of digital waxing software for dental anatomy education. Dental students were introduced to digital waxing during a dental anatomy course, and were requested to finish a voluntary survey. Students strongly agreed (18.2%) or agreed (48.0%) with the statement "digital waxing contributed to my learning of dental anatomy", and strongly agreed (29.9%) and agreed (55.8%) with the statement "The digital waxing software helped develop my wax-up skills". The digital waxing software may be effective for dental anatomy education, but students do not believe digital waxing can be a replacement for conventional wax-up practice.
