Virtual reality approach for orthodontic education at School of Stomatology, Jinan University

The development of virtual reality (VR) has exerted an enormous impact on higher education. However, the VR application in dental education is still at an early stage in China. This study explored the usability of a VR application in training the practical skills of dental students.We first utilized the "system usability scale" (SUS) to verify the validity of the VR application in this study. Next, the VR training on orthodontic bracket bonding was experienced by the participants. The subsequent survey was delivered to collect the participants' perception and evaluation of the VR system application in training the practical skills of prospective dentists.The SUS score was 76.17 ± 9.89, suggesting an above-average evaluation of the system's usability and maturity. The response from the questionnaire supplied relatively positive responses to the VR system application on "user experiences," "perceived usefulness of VR application on orthodontics," and "perceived ease of manipulation." The male students exhibited strong interest in manipulating the VR system and were more capable of manipulating the VR system than the female students. VR experience did not affect the participants' responses to the questions.Overall, the use of VR in dental education achieved the expected outcomes. Most students identified the VR training as an enjoyable learning process, and it could be repetitively experienced without further costs, which might have potential positive effects on long-term learning outcomes, although there is room to further improve the effectiveness evaluation of VR.
