Trauma-related sequelae in individuals with a high level of dental anxiety. Does this interfere with treatment outcome?
This study assessed trauma-related sequelae of 56 highly anxious patients attending a dental fear clinic. It was also examined whether such symptomatology interferes with anxiety reduction in response to a cognitive-behavioral treatment approach. About 34 patients (59%) indicated that they had experienced one or more aversive dental events that could explain the onset of their dental anxiety. There was no difference between the dental anxiety scores of patients who reported such a background and those who did not. Severity of trauma-related symptomatology was indexed by the Impact of Event Scale (IES). The mean IES score of patients with a traumatically induced dental fear was remarkably high (33.0; SD=19.7). Furthermore, there was a strong direct relationship between severity of trauma-related symptomatology and severity of dental anxiety (shared variance was 38%). Two patients (10%) met all DSM-IV diagnostic criteria for Posttraumatic Stress Disorder (PTSD) on the basis of the Self-Rating Scale for PTSD. However, no evidence was found to suggest that either a traumatic background, or level of trauma-related symptomatology, has a negative effect on treatment outcome.
