Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in visual analogue scale anxiety scores after tooth extraction

    The visual analogue anxiety scale from 0 to 10, with meaning no anxiety and 10 very high anxiety

    In the 5 minutes after the end of surgery

Secondary Outcomes (6)

  • Overall satisfaction between the group using RELAX glasses and the group following the usual course (without RELAX glasses) measured by a visual analogue scale

    Immediative postoperative

  • Variation in pain between entering and leaving the surgical technical platform between the 2 arms using a visual analogue scale

    In the 5 minutes after the end of surgery

  • Rate of patients receiving at least one analgesic

    After local anesthesia

  • Surgeon's satisfaction with the feasibility of the procedure in a patient wearing RELAX glasses filling in a self-assessment questionnaire

    Immediative postoperative

  • Pre-existing anxiety, only in patients receiving RELAX glasses, measured with the STAI-YB score

    7 days (+/-3 days) after surgery

  • +1 more secondary outcomes
