Primary outcomes

  1. Change in the Anxiety Score

    Time frame: 1 minute after the participant sits the dental unit and 10 minutes after

    Patients complete the State-Trait Anxiety Inventory (STAI) while seated in the dental unit. Ten minutes after the glasses are worn, patients fill out the anxiety scale again. Changes in the scores are the primary outcome of the study. The scale range is 20-40. A lower score means better results.

Secondary outcomes

  1. Change in the oxygen saturation

    Time frame: 1 minute after the participant sits the dental unit and 10 minutes after

    Saturation measurement is done from the fingertip using a pulse oximeter one minute after the patient sits in the dental unit and after ten minutes. Changes in the scores are the secondary outcome of the study. The average value is above %90.

  2. Change in the pulsation

    Time frame: 1 minute after the participant sits the dental unit and 10 minutes after

    Pulsation was measured from the fingertip by a pulse oximeter one minute after the patient sat in the dental unit and after ten minutes. Changes in the scores are the secondary outcome of the study. The average value is between 65 and 75.

  3. Intraoperative Pain Score

    Time frame: 1 minutes after the surgery

    Measuring the pain felt by the patient after the operation with the help of the visual analog scale. The range of Scala is 0-10. A lower score means better results.

  4. Change in the salivary cortisol level

    Time frame: 1 minute after the participant sits the dental unit and 10 minutes after

    Measuring the salivary cortisol level one minute after the patient sits in the dental unit and after ten minutes. Changes in the levels are the secondary outcome of the study.

  5. Change in the salivary alfa-amilase level

    Time frame: 1 minute after the participant sits the dental unit and 10 minutes after

    Measuring the salivary alfa-amylase level one minute after the patient sits in the dental unit and after ten minutes. Changes in the levels are the secondary outcome of the study.
