The Effectiveness of Audiovisual Distraction Behavior Guidance Technique in Children With Dental Anxiety

This randomized, two-armed, placebo-controlled, cross-over, controlled trial aimed to evaluate the effect of virtual reality exposure therapy (VRET) on dental anxiety, pain, and behaviour among children undergoing dental treatment under local anaesthesia. The null hypotheses were as follows: VRET has no effect on reducing dental anxiety and dental pain scores of participants; and there is no difference between subjective and objective measure scores of dental anxiety and pain when VRET and attention palcebo-controlled (APC) groups are used to reduce anxiety in children undergoing dental treatment with local anaesthesia.
