Digital education using virtual-reality simulators is essential for precise learning in modern education. This study aimed to develop a virtual-reality dental system for tooth preparation training and assess pre-virtual-reality experiences and perceptions of its potential benefits. We evaluated the post-virtual-reality experience in terms of the effectiveness of the virtual-reality system. The virtual-reality platform development phase involved learning- and assessment-based frameworks for participants. The first step involved creating a storyboard for a virtual dental clinic environment using virtual-reality glasses. This simulated a dental chair-like setup with instruments and tools, allowing participants to practice dental procedures. This study utilized a mixed-methods approach to assess participants' experience with virtual reality in dental education using a tooth preparation simulation system and evaluated post-virtual reality measures, including the system usability scale, usefulness, educational effectiveness, and participant attitudes through structured survey questionnaires. This study included 150 participants (49 dental students, 52 dental interns, and 49 faculty members). Most participants were females (76%). Significant differences were observed in attitude scores between students and faculty members, with third-year dental students having more positive attitudes toward the integration of virtual-reality in dental education. No significant differences were found in system usability, usefulness, or assessment scores between the groups. The virtual-reality dental module system shows promise for improving dental education. The varied responses from different user groups should be considered to ensure successful implementation and acceptance.
