摘要：Background
Due to the inherent characteristics of immersion, imagination, and interactivity in virtual reality (VR), it might be suitable for non-drug behavior management of children in dental clinics. The purpose of this trial was to measure the role of VR distraction on behavior management in short-term dental procedures in children.
Methods
A randomized clinical trial design was carried out on 120 children aged between 4 and 8 years to identify the comparative efficacy of VR and tell-show-do (TSD) to improve behavioral management during dental procedures. The primary outcomes were evaluated anxiety, pain, and compliance scores in perioperative children. The levels of operative anxiety and pain were assessed using the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) and Wong Baker FACES Pain Rating Scale (WBFS), respectively. The Frankl Behavior Rating Scale (FBRS) was tested before and during dental procedures. The length of the dental procedure was compared between both groups after treatment.
Results
The average anxiety and behavioral scores of the VR group significantly reduced compared with the control. The decreased anxiety score for the VR group and control group were 8 (7, 11) and 5 (5, 7),
p < 0.05. The compliance scores of the control group during treatment were 3 (2, 3), and the same in the VR intervention were 3 (3, 4),
p = 0.02. A significant reduction in pain was observed when using VR distraction (
p < 0.05). Comparing the length of the dental procedure, the VR group (19.0 2 ± 5.32 min) had a shorter treatment time than the control group (27.80 ± 10.40 min).
Conclusion
The use of VR significantly reduced the anxiety and pain of children and the length of the dental procedure and improved the compliance of children that underwent short-term dental procedures without an adverse reaction.
