Effectiveness of virtual reality as a distraction on anxiety and pain during impacted mandibular third molar surgery...

The aim of this study was to assess the effectiveness of Virtual Reality (VR) in reducing anxiety and pain during impacted mandibular third molar extraction under local anesthesia.

The study was designed as a prospective clinical study covering 74 respondents over 20 years of age. Surgical extraction of both impacted mandibular third molars was performed in two phases, two weeks apart. In the first phase, surgical extraction of the tooth was performed following the standard procedure (Non VR), and in the second phase (VR), we used VR goggles as an auxiliary tool for distraction during the procedure. Face scale was used to assess the level of pain. Heart rate values were recorded by means of wristbands. After both procedures, the patients filled out a modified post-clinical satisfaction questionnaire.

During the procedure with VR goggles, the respondents had significantly lower pain values during the application of anesthesia, as well as during the surgical extraction of the third molar. There was no statistically significant difference in the level of pain during both surgical procedures with regard to the gender and age. Heart rate values in both phases of the study were not significantly different before the application of anesthesia. When VR goggles were used, the respondents had significantly lower heart rate values before the procedure, as well as during the procedure. Analysis of answers to the post-clinical questionnaire measuring satisfaction with VR technology shows that over 90% of respondents did not experience any VR-related discomfort during the surgery.

The VR distraction concept applied during impacted third molar surgery under local anesthesia can help reduce the patients' anxiety and acute pain levels.
