The application of virtual reality has become increasingly extensive as this technology has developed. In dental education, virtual reality is mainly used to assist or replace traditional methods of teaching clinical skills in preclinical training for several subjects, such as endodontics, prosthodontics, periodontics, implantology, and dental surgery. The application of dental simulators in teaching can make up for the deficiency of traditional teaching methods and reduce the teaching burden, improving convenience for both teachers and students. However, because of the technology limitations of virtual reality and force feedback, dental simulators still have many hardware and software disadvantages that have prevented them from being an alternative to traditional dental simulators as a primary skill training method. In the future, when combined with big data, cloud computing, 5G, and deep learning technology, dental simulators will be able to give students individualized learning assistance, and their functions will be more diverse and suitable for preclinical training. The purpose of this review is to provide an overview of current dental simulators on related technologies, advantages and disadvantages, methods of evaluating effectiveness, and future directions for development.

“…The face validity of the simulator is the degree to which the training situation resembles the real clinical situation [14]. The criterion for achievement is uniform positive evaluations of the simulator from users of different educational backgrounds [15].…”

“…Dental simulators will be the main method for preclinical skills training in the future. Currently, in many fields, such as flight [23] and laparoscopic surgery [15], simulation is a mandatory training stage before the learner is allowed to perform the relevant skills in a real situation [14]. As the development of technology does not happen overnight, dental simulators are in a phase of continuous development and breakthroughs.…”

Background Virtual reality (VR) dental simulators are currently used in preclinical skills training. However, with the development of extended reality technologies, the use of mixed reality (MR) has shown significant advantages over VR. Objective This study aimed to describe the research and development of a newly developed MR and haptic–based dental simulator for tooth preparation and to conduct a preliminary evaluation of its face validity. Methods A prototype of the MR dental simulator for tooth preparation was developed by integrating a head-mounted display (HMD), special force feedback handles, a foot pedal, computer hardware, and software program. We recruited 34 participants and divided them into the Novice group (n=17) and Skilled group (n=17) based on their clinical experience. All participants prepared a maxillary right central incisor for an all-ceramic crown in the dental simulator, completed a questionnaire afterward about their simulation experience, and evaluated hardware and software aspects of the dental simulator. Results Of the participants, 74% (25/34) were satisfied with the overall experience of using the Unidental MR Simulator. Approximately 90% (31/34, 91%) agreed that it could stimulate their interest in learning, and 82% (28/34) were willing to use it for skills training in the future. Differences between the 2 study groups in their experience with the HMD (resolution: P=.95; wearing comfort: P=.10), dental instruments (P=.95), force feedback of the tooth (P=.08), simulation of the tooth preparation process (P=.79), overall experience with the simulation (P=.47), and attitude toward the simulator (improves skills: P=.47; suitable for learning: P=.36; willing to use: P=.89; inspiring for learning: P=.63) were not significant. The Novice group was more satisfied with the simulator’s ease of use (P=.04). There were significant positive correlations between the overall experience with the simulation and the HMD’s resolution (P=.03) and simulation of the preparation process (P=.001). Conclusions The newly developed Unidental MR Simulator for tooth preparation has good face validity. It can achieve a higher degree of resemblance to the real clinical treatment environment by improving the positional adjustment of the simulated patients, for a better training experience in dental skills.

“…It has demonstrated high criterion validity in predicting performance in direct observation of procedural skills 36 and high construct validity in detecting experience in surgery. 37 Participants completed three main tasks on the simulator -pick up and drop ( Simple Technical Task completed three times ), needle threading ( Moderately Complex Technical Task completed three times ) and sort the rings ( Technical and Cognitive Task completed one time ), ascending in order of difficulty. Their performance was assessed on three main metrics: time taken to complete the task, number of errors made, and economy of motion or path-length of the right and left instruments.…”

“…While this study shows sleep deprivation impacts attention, debate exists on whether sleep deprivation impairs other executive functions of memory scanning, efficiency and resistance to proactive interference, 49 which also impacts decision-making in surgical practice. While simulated environments have been found to correlated to surgical experience, 37 the role of the environment and team-support may mitigate known areas of decrement in surgical performance, or alternatively create further stressors on performance and thus warrants further investigation. Variables associated with sleep such as sleep quality should be accounted for through an expansion of studies already looking at sleep and activity tracking devices on surgeons, 50 and linking this with performance outcomes both in simulation and real-life.…”
