Summary

This study tested whether wearing colored glasses (green, red, or blue) for 10 minutes before a tooth extraction could reduce anxiety and pain. 84 adults who had not had a wisdom tooth removed before took part. Researchers measured anxiety using a standard questionnaire and checked oxygen levels to see if the colors helped people feel calmer during the procedure.
