The vast majority of tooth extraction surgery is performed under local anaesthetic, and can be a source of anxiety. In their 2015 article, Appukuttan et al studied the anxiety felt by 1148 patients prior to tooth extraction, and reported up to 82% of patients anxious before a procedure.

In 2020, Yamashita et al demonstrated the value of virtual reality in reducing patient anxiety during the extraction of three impacted mandibular molars, with no clear effect on the pain felt by the patient.

The use of a virtual reality headset has been shown to reduce anxiety in dental surgery or in hand surgery under local anesthesia with the WALANT technique. On the other hand, virtual reality and the use of 3D can cause discomfort and side effects such as nausea and dizziness. Audiovisual distraction is also known to be effective in reducing pain and anxiety in patients, with fewer side effects.

The investigators have therefore chosen to use RELAX® eyewear. They wish to study its effect on anxiety, pain and overall patient and surgeon satisfaction.
