The Impact of Virtual Dental Clinic Color and Image Modifications on Anxiety Reduction in Undergraduate Dental Students
Main Article Content
Abstract
Dental students often experience stress due to the curriculum’s theoretical and practical demands, which can negatively affect their well-being. Previous research suggests that room colors and images can reduce anxiety in certain populations. However, no studies have examined this effect among dental students. Therefore, this study investigated how color and visual imagery in dental clinics affect anxiety levels in dental students. Participants were dental students experiencing state anxiety. They completed a modified version of the State-Trait Anxiety Inventory (STAI) Form Y-1 before and after entering a virtual reality (VR) dental clinic with altered environmental features. Three types of visual interventions were tested: 1) changing wall colors to blue, green, or yellow; 2) adding images of mountain, sea, or nautilus shell; and 3) combining the most preferred color and image. Paired t-tests were used to analyze changes in anxiety scores, and intergroup differences were examined using the Kruskal-Wallis test, followed by the Wilcoxon Signed-Rank test. Anxiety significantly decreased after exposure to blue and yellow wall colors (p < 0.05), with blue being the most preferred. Notably, blue increased positive anxiety scores (PA) and decreased negative anxiety scores (NA) significantly (p < 0.05), while yellow only decreased NA scores significantly (p < 0.05). Mountain and sea images also significantly reduced anxiety (p < 0.05), with the mountain image being the most preferred. Both types of images increased PA and decreased NA scores significantly (p < 0.05). The combination of blue walls and a mountain image was effective in reducing anxiety in all participants, but changing the wall color or adding a nature-related image alone was as effective as doing both together. These findings suggest that specific environmental elements—such as color tones and images—within a VR clinical setting can significantly reduce anxiety levels in dental students. Therefore, incorporating simple visual modifications into dental clinic design may be an effective strategy to reduce stress in educational healthcare environments. This highlights the importance of environmental design in supporting student well-being.
