Abstract

Purpose/objectives The aim of this study was to quantitatively investigate the impact of stereoscopic three-dimensional (3D) vision on students’ performance when compared with that of two-dimensional (2D) vision in a 3D virtual reality (VR) simulator. Methods Twenty-four dental students (second- and fourth-year BDS) were assigned to perform three operative tasks under 3D and 2D viewing conditions on a Virteasy (HRV) simulator. Groups were crossed over and all students performed the same tasks under the alternate viewing conditions. The performance was evaluated by (1) accuracy, (2) outside target area removal, and (3) tooth cutting time, automatically using the generated feedback. Results Twenty-one participants completed all sessions. The results revealed a statistically significant effect of 3D vision over 2D vision on students’ performance in terms of accuracy (p = 0.035). Stereoscopic 3D vision showed significant effect on outside target area removal in the first task (p = 0.035). Tooth cutting time was the same under both conditions (p = 0.766). The findings revealed improvement in accuracy score and reduction in outside target area removal over the course of the experiment under both conditions. Comparing the difference in 3D effect in the early and advanced learning groups revealed no significant difference among the groups (p > 0.05). Conclusion Utilizing stereoscopic 3D vision in the training session improved students’ perception of depth which led to more accurate tooth cutting within the target area, and less outside target area removal. However, 3D shows a limited impact on task completion time.
