Does Augmented Visual Feedback from Novel,Multicolored, Three-Dimensional-Printed Teeth Affect Dental Students' Acquisition of Manual Skills?

Although three-dimensional (3D) printing technology is increasingly used in dental education, its application regarding the provision of online visual augmented feedback has not been tested. Thus, this study aimed to: (1) develop two generations of multicolored 3D-printed teeth that provide visual augmented feedback for students conducting the cavity preparation process, (2) assess students' clinical performance after training on the 3D models, and (3) acquire student feedback. For the first-generation model, augmented feedback was obtained from five 3D-printed teeth models for five cavity preparation procedures. Each model comprised three layers printed in green, yellow, and red indicating whether preparation was acceptable, limited, or unacceptable, respectively. The study used a crossover design in which the experimental group trained on five multicolored models and 10 standard plastic teeth, and the control group trained on 15 standard plastic teeth. Students gave positive feedback of the methodology but complained about the printed material's hardness. Therefore, a second-generation model was developed: the model's occlusal plane was replaced with a harder printed acrylic material, and the experiment was repeated. During training, instructors provided external terminal feedback only for performance on standard plastic teeth. Manual grades for cavity preparations on standard plastic teeth were compared. No significant differences were found between the control and experimental groups in both generations' models. However, less instructor time was needed, and similar clinical results were obtained after training with both generations. Thus, multicolored 3D-printed teeth models promote self-learning during the process of acquiring manual skills and reduce student dependency on instructors.     

Using a 3D food printer as a teaching tool: Focus groups with dietitians,teachers, and nutrition students

Three‐dimensional (3D) food printing is a new technology that can be used to produce personalized and customized food products. However, very little research has been completed on how 3D food printers could be used as educational tools. As such, the objective of this study was to evaluate how teachers (n = 6), dietitians (n = 6), and nutrition students (n = 11) envision the use of 3D food printers when disseminating information about food and nutrition. Focus groups were conducted with teachers, dietitians, and nutrition students. Initially, the participants were introduced to the concept of 3D food printing and then they were asked how they could use a 3D food printer in their teachings. The participants did not feel that a 3D food printer would enhance their teaching and instead felt it could confuse or frighten people. Also, all of the participants were worried about learning how to 3D print foods. The participants did state that people would be interested in watching a 3D food printer. Furthermore, the teachers and nutrition students indicated they thought a demonstration of a 3D food printer would lead to more interest in food and nutrition. Additionally, they thought a 3D food printer could be used to create visually appealing foods. Overall, until 3D food printers are found in residential and commercial kitchens, the participants did not think it would enhance their teachings; however, they did indicate that 3D food printing demonstrations could lead to students being interested in the food and nutrition fields.     

浅谈在MFC中实现打印功能的方法

在MFC编程中,虽然系统对用向导生成的文档视图程序提供了打印功能,但如果对自动生成的框架程序不做任何改进,打印出来的文档或图形跟屏幕上的显示就不成比例,而对在基于对话框的应用程序中如何实现打印功能也没有太多的介绍。文章对MFC的打印机制进行了深入的分析,介绍了在文档视图框架下以及在对话框的应用程序中实现打印功能的方法。     

Evaluation by medical students of the educational value of multi‐material and multi‐colored three‐dimensional printed models of the upper limb for anatomical education

For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on‐going. We hypothesize that three‐dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi‐colored and multi‐material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ～1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi‐colored, multi‐material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.
