Do Dental Anxiety Questionnaires Raise Anxiety in Dentally Anxious Adult Patients? A Two-Wave Panel Study

OBJECTIVE: To test whether or not dentally anxious patients attending the dentist for an appointment become more anxious when completing a dental anxiety questionnaire. BASIC RESEARCH DESIGN: Patients were initially screened to include only those who were dentally anxious. A pre- and post-test was planned with the completion of the Modified Dental Anxiety Scale (MDAS) questionnaire as the intervention. CLINICAL SETTING: Two dental access centres in the North West of England. PARTICIPANTS: Initially, 583 patients were screened. Of these, 182 (31%) were found to be dentally anxious and were recruited into the study. MAIN OUTCOME MEASURES: State-Trait Anxiety Inventory Scale Short Form. RESULTS: State anxiety did not change with the completion of the MDAS questionnaire in either designated dental phobics (MDAS >or=19) or those classified as non-phobics (MDAS <19). CONCLUSIONS: The MDAS can be used to assess dental anxiety without raising anxiety in patients with or without self-reported dental phobia.
