A Virtual Reality Simulator for Teaching and Evaluating Dental Procedures

Summary Objectives: We present a dental training system with a haptic interface that allows dental students or experts to practice dental procedures in a virtual environment. The simulator is able to monitor and classify the performance of an operator into novice or expert categories. The intelligent training module allows a student to simultaneously and proactively follow the correct dental procedures demonstrated by an intelligent tutor. Methods: The virtual reality (VR) simulator simulates the tooth preparation procedure both graphically and haptically, using a video display and haptic device. We evaluated the performance of users using hidden Markov models (HMMs) incorporating various data collected by the simulator. We implemented an intelligent training module which is able to record and replay the procedure that was performed by an expert and allows students to follow the correct steps and apply force proactively by themselves while reproducing the procedure. Results: We find that the level of graphics and haptics fidelity is acceptable as evaluated by dentists. The accuracy of the objective performance assessment using HMMs is encouraging with 100 percent accuracy. Conclusions: The simulator can simulate realistic tooth surface exploration and cutting. The accuracy of automatic performance assessment system using HMMs is also acceptable on relatively small data sets. The intelligent training allows skill transfer in a proactive manner which is an advantage over the passive method in a traditional training. We will soon conduct experiments with more participants and implement a variety of training strategies.

BACKGROUND Sufficient emergency preparedness is the key factor to respond effectively and recover from major emergent infectious diseases (MEID). However, in the face of MEID, public emergency preparedness is insufficient, so it is urgent to improve public emergency preparedness. The rapid development of virtual reality and human-computer interaction provides unprecedented opportunities for innovative education methods. OBJECTIVE To design a virtual reality interactive training system (VRITS) to improve public emergency preparedness under MEID, so that the public can respond effectively and recover from MEID. METHODS This study takes the interactive narrative theory, situated learning theory and human-computer interaction theory as the theoretical framework to guide the design of software. Using literature research method and Delphi method, consulting and interviewing multi-disciplinary experts such as pedagogy, medicine, psychology, public health and computer to determine the educational content framework and operating system framework of the VRITS. RESULTS The VRITS is named the People’s War Against Epidemic. The educational content framework includes 21 knowledge, emotion and behavior skills in six aspects, such as cooperating with prevention and control work, improving basic equipment, ensuring personal safety, preparing economic resources, managing self-emotion, and improving emergency response ability. The operating system framework includes virtual interactive training module, knowledge corner module, intelligent evaluation module and community forum module, and the core module is a virtual interactive training module. In this module, users control the virtual characters to move in various scenes in the community, and then identify and analyze the controllability and harmfulness of the evolving epidemic and selects the correct prevention and control strategy to avoid infection by themselves and others. CONCLUSIONS The People’s War Against Epidemic creates a realistic learning situation for the trainers, enhances the immersion and experience of the trainers, enriches the theoretical system and education resource database of emergency preparedness training under the MEID, and improves the effectiveness, fairness, accessibility and participation of education.

The Impact

Abstract Background: There are limited studies that assess the level of confidence among the final year dental students in the ability to conduct key dental procedures. The present study aims to assess the perception and confidence level of final year dental students ‎from the School of Dentistry at the University of Jordan to perform essential dental procedures ‎across various dental disciplines; to assess the effect of competencies implementation in curricula on the confidence level of students. Methods: An electronic questionnaire was answered by two cohorts of final year dental students: one group in 2016 before the implementation of the competency-based assessment system (group 1, n = 153), and the other in 2019 after the implementation of this system (group 2, n = 199). The two groups were compared regarding the degree of confidence in conducting key dental procedures. The data were analysed using SPSS statistics. Statistical significance was set at 0.05 level.Results: Statistically significant differences between the two groups regarding the confidence levels were found in 5 out of 20 prosthodontic procedures (placing treatment plan of removable partial dentures, using semi-adjustable articulator, giving oral hygiene instructions (OHIs) for denture patients, dealing with complete denture post-insertion complaints, and giving OHIs for denture patients); and in 5 out of 20 conservative Dentistry procedures (placing treatment plan of removable partial dentures (RPD), using semi-adjustable articulator, giving OHI's for Denture Patients, dealing with complete denture (CD) post-insertion complaints and giving OHI's for Denture patients). These differences were in favor of grope 2.Conclusion: This study has shown that final year dental students generally have high confidence levels in doing simple dental procedures and less confidence in more complex ones, thus additional focus on such complex procedures is advised during post-graduation training and before entitlement for practice licensing. Competency-based dental education is an advantageous over classical dental training systems, and thus should be maintained and continuously enhanced.

This paper looks to expand on the INEC 2016 paper ‘The future role of virtual reality within warship support solutions for the Queen Elizabeth Class aircraft carriers’ presented by Ross Basketter, Craig Birchmore and Abbi Fisher from BAE Systems in May 2016 and the EAAW VII paper ‘Testing the boundaries of virtual reality within ship support’ presented by John Newell from BAE Systems and Simon Luck from BMT DSL in June 2017. BAE Systems and BMT have developed a 3D walkthrough training system that supports the teams working closely with the QEC Aircraft Carriers in Portsmouth and this work was presented at EAAW VII. Since then this work has been extended to demonstrate the art of the possible on Type 26. This latter piece of work is designed to explore the role of 3D immersive environments in the development and fielding of support and training solutions, across the range of support disciplines. The combined team are looking at how this digital thread leads from design of platforms, both surface and subsurface, through build into in-service support and training. This rich data and ways in which it could be used in the whole lifecycle of the ship, from design and development (used for spatial acceptance, HazID, etc) all the way through to operational support and maintenance (in conjunction with big data coming off from the ship coupled with digital tech docs for maintenance procedures) using constantly developing technologies such as 3D, Virtual Reality, Augmented Reality and Mixed Reality, will be proposed. The drive towards gamification in the training environment to keep younger recruits interested and shortening course lengths will be explored. The paper develops the options and looks to how this technology can be used and where the value proposition lies.
