Study summary

Clinical trial of an application of cognitive behavioural one-session therapy method with patients who have severe or average dental fear/anxiety measured by Modified Dental Anxiety Scale (MDAS). The intervention consists of two different parts: a diagnostic interview and one-session treatment of dental care. The method is based on One-Session Therapy manual (Öst \& Skaret, 2013). 30 minimum 18 years old adults takes part to the study. They comes from three different places,primary care clinic, community dental care and dentist´s teaching clinic.

Read the 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.
