The purpose of this study was to develop prototype of virtual reality(VR) simulation with malocclusion models and evaluate its applicability. Task abilities, task completion time, and a satisfaction survey were compared between dentist trainees and dental students.
Participants were instructed to observe virtual malocclusion models and then performed three tasks to diagnose the type of malocclusion, determine clinical findings and develop treatment plans. Their satisfaction with the simulation experience were evaluated using a questionnaire containing five questions.
Task abilities of trainees related to clinical features and treatment plans were significantly higher than that of students(p < 0.01). In both groups, the task completion time for the second case was significantly reduced compared to that for the first case(p < 0.01). The satisfaction survey showed high scores and positive responses for this simulation in both groups. If the prototype of VR simulation is continuously advanced, it will be applicable for orthodontic education in pediatric dentistry.

The purpose of this study was to evaluate the applicability of virtual reality simulation after experience of dental caries diagnosis for dental students before exposing to clinical pediatric practice. A pediatric patient model of a five-year-old child with primary dentition was developed and a caries model that is amenable to VR(virtual reality) diagnosis was organized and set-up. The dental student’s were allowed to use the simulated model for fifteen minutes and their experiences were evaluated using a self-reported questionnaire to evaluate presence and usability of this application. Overall, virtual presence and appearance area of the simulation were highly scored. The result indicates that the VR model has no significant difference from the actual clinical caries regardless of grade of students, gender and VR experience. If the prototype is continuously advanced, its applicability in dental education will increase.

Purpose: To sustain behavior change, an intervention strategy that considers the contribution of affect to daily physical activity behavior regulation is needed. Although virtual reality-based physical activity interventions have the potential to improve emotional status, interventions using virtual reality videos in a free-living environment are lacking. This pilot study assessed the feasibility and preliminary efficacy of a home-based intervention using 360-degree virtual videos and wearable activity trackers to improve mood and physical activity. Methods: A one-group pilot study of 12 middle-aged migrant women asked participants to watch virtual reality videos and perform moderate-intensity walking 5 days per week for 4 weeks, then complete surveys and focus group interviews. The intervention’s feasibility and preliminary efficacy were assessed by examining recruitment, retention, adherence, acceptability, mood, physical activity, and exercise self-efficacy. Results: A word-of-mouth approach was effective for recruiting participants. Although the weekly intervention adherence rate ranged from 53.5% to 83.5%, retention (92.3%) and acceptability (91.7%) were high. Participants were satisfied with the “visual status indicators,” “sense of accomplishment and confidence,” “emotional engagement and sense of presence,” “joy from exercise,” “external motivation through supervision,” “easy to control virtual reality device,” and “extra benefits” of the intervention. Participants had significant decreases in negative affect (p=.016). Positive affect, physical activity, and exercise self-efficacy showed trends toward improvement. Conclusion This home-based intervention employing virtual reality videos and Fitbit activity trackers is feasible and shows preliminary efficacy in improving mood. Further research is warranted to evaluate its effectiveness in a more rigorous randomized controlled trial.
