Detailed Description

Purpose is to compare diagnostic interview (n=20) to diagnostic interview and one-session treatment of dental care (n=10). Partners come from three different places, 10 from each: public and private dental care and dental school. Participants from dental school take part to one-session treatment. All participants have normal dental care before final interview. Hypotheses is that dental fear/anxiety will decrease one category (5 points) when measured by Modified dental anxiety scale (MDAS) before the intervention and after normal dental care. Visual Analogue Scale is used to measure the strength of unpleasant feeling before and after intervention in both groups.

Interventions

  • Behavioral: Diagnostic interview
    • A profound interview to declare causes for negative thoughts, assumptions and beliefs towards dental care. Participants come from public and Private dental care.
  • Behavioral: Combined interview and treatment.

  • Experimental: Combined interview and treatment
    • Intervention for this group include both the diagnostic interview and one session treatment.

Clinical Trial Outcome Measures

Primary Measures

  • Change in dental fear
    • Time Frame: 6 months
    • Change in fear is measured by a questionnaire called Modified Dental Anxiety Scale (MDAS). Change in fear is indicated by change in mean value of the MDAS between baseline and follow-up measurement

Secondary Measures

  • Compliance to care
    • Time Frame: 6 months
    • Compliance to care is indicated if treatment defined before the baseline interview can be wholly executed. If patient interrupt treatment or cannot be executed at all after baseline interview, then compliance is not fulfilled.
