Summary

Dental anxiety is a significant barrier to the acceptance of regular dental care, and has many negative consequences. A study by Dailey et al. (2002) found that providing the dentist with information of the high level of a patient's dental anxiety prior to treatment using the Modified Dental Anxiety Scale (MDAS, Humphris et al., 1995), lead to a significant reduction in state anxiety from pre- to post- dental consultation compared to a control group. The current study aimed to replicate the study by Dailey et al. (2002), and to further explore whether the reduction in state anxiety associated with the MDAS could be explained by a change in dentist behaviour on receiving it, or a change in patient expectancy about the treatment session, or both.

The design was a randomised control trial involving three groups, which aimed to manipulate possible changes in dentist behaviour and patient expectancy. In Group 1, the MDAS was left at reception, as expected by the patient. In Group 2, the dentist received the MDAS, although the patient did not expect this. In Group 3 the dentist received the MDAS and the patient did expect this. The sample (N=182) was taken from two dental access centres, and included participants obtaining a score of 19 or above, or 5 on any one item of the MDAS. Pre- and post-dental consultation measures of state anxiety were taken using the six-item short-form of the state scale of the Spielberger State-Trait Anxiety Inventory (STAI-S, Marteau \& Bekker, 1992).
