This study aimed to systematically review the literature to evaluate the effectiveness of virtual reality in reducing anxiety and pain in patients undergoing third molar surgeries. Clinical trials evaluating patients who used virtual reality (VR) compared with no VR in the management of pain or anxiety after third molar extractions were included. A literature search was conducted in five electronic databases to identify relevant articles: Medline (PubMed interface), Web of Science, Virtual Health Library, Embase, and Scopus. There were no restrictions on the time or language of publication. The risk of bias was assessed using the Cochrane Risk of Bias Tool for Randomised Trials (RoB 2.0). A total of six studies were included in the qualitative analysis and three in the quantitative analysis. The results of the meta-analyses on anxiety revealed that patients in the intervention group before VR already showed less anxiety compared to those in the control group (-0.28 [-0.44 to -0.13, 95%CI] I²=24.51%. In the post-intervention evaluation, the group that received VR remained with a lower level of anxiety and a slight reduction compared to the pre-intervention. (-0.34 [-0.49 to -0.19, 95%CI] I²=36.61%. Virtual reality can be a clinical resource in dental care because it seems to cause a small reduction in anxiety, and with still uncertain results in the reduction of postoperative pain in extractions of third molars.
