Primary Outcome Measures:
  • Dental anxiety [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Dental anxiety is assessed by the Dental Anxiety Scale (DAS) and the Dental Fear Survey (DFS).

  • Dental anxiety [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Dental anxiety is assessed by the Dental Anxiety Scale (DAS) and the Dental Fear Survey (DFS).

  • Dental anxiety [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Dental anxiety is assessed by the Dental Anxiety Scale (DAS) and the Dental Fear Survey (DFS).


Secondary Outcome Measures:
  • General psychopathology [ Time Frame: 4 weeks, 3 months, 12 months ] [ Designated as safety issue: No ]
    General psychopathology is assessed by the Brief Symptom Scale (BSI).

  • Anxiety and depression [ Time Frame: 4 weeks, 3 months, 12 months ] [ Designated as safety issue: No ]
    Anxiety and depression are assessed by the Hospital Anxiety and Depression Scale (HADS).

  • Behavioral test [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Dentral anxiety is assessed during a dental visit before and after treatment/wait-list control condition by means of a standardized behavior obeservation and interview.

  • Dental treatment [ Time Frame: 3 months, 12 months ] [ Designated as safety issue: No ]
    Does the patient tolerate dental treatment within 3 and 12 months after Eye Movement Desensitization and Reprocessing (EMDR)?

Wait-list control group. EMDR treatment takes place after 4 weeks of no treatment which represents the wait-list comparison interval.

Detailed Description:

Dental phobia represents a clinical condition that affects 5-15% of the community and is characterized by severe anxiety of dental treatment which leads to avoidance of treatment and, as a consequence, severe dental as well as psychosocial problems.

Eye Movement Desensitization and Reprocessing (EMDR) has been developed for the treatment of patients with post traumatic stress disorder (PTSD). Its efficacy in PTSD patients has often been demonstrated in randomized controlled trials.

Recently it has been demonstrated that dental phobia is often induced by traumatic events during dental treatment and goes along with symptoms of PTSD in numerous patients.

A pilot study (de Jongh et al. 2002) gave hints on the efficacy of EMDR in four dental phobia patients with a history of traumatization during dental treatment.

This randomized wait-list control study aims to evaluate the efficacy of EMDR in a larger sample of dental phobia patients.
