Evaluation of a one session VR - enhanced Video exposure therapy for dental phobia. Diagnosed dental phobics will be randomly assigned to one of two conditions: (1) Psychoeducation + VR exposure (2) Psychoeducation + Video Control treatment. Prior to getting the therapy, participants will be evaluated with a questionnaire battery, diagnosed with a structured clinical interview and will participate in a psychophysiological symptom assessment. Then, after a 2-week waiting period, participants again fill in questionnaires, and the Intervention will take place. Within 2-weeks after the second questionnaire assessment participants will be screened with the structured interview again and will fill in questionnaires.
