3. The Concept of Anxiety Fear – ‘individual’s emotional response to a perceived threat or danger…incorporates negative cognitive appraisals; physiological changes; behavioural cues’ (Milgrom et al., p5) (fight or flight)

4. Dental Anxiety Anxiety – ‘response to situations in which the source of threat to the individual is ill-defined, ambiguous, or not immediately present’’ (Milgrom et al., p5) Anticipatory anxiety

5. Dental Phobia ‘a marked and persistent fear of clearly discernible, circumscribed objects or situations. Exposure to the phobic stimulus almost invariably provokes an immediate anxiety response’ ‘….prolongation of the avoidance response resulting in significant distress or interferes with one’s social or role functioning ‘ (DSM IV critera, 1994)

6. Dental Phobia Dental phobia shares features of anxiety and fear. It shares features that are apparent with other well known phobias such as spider and rat phobias. These include: • Avoidance • Suffers unable to explain their reactions • Embarrassment and shame

7. MDAS • The MDAS asks patients to imagine themselves in 5 different dental situations and to rate how they would react on a 5-point scale. • Three scores can be calculated. All questions are added to give a “total” score (max. 25); questions 1-4 can be summed to give a “general dental anxiety” score (max. 20); and question 5 can be summed to give a “needle phobia” score (max.5). • The cut-off for clinically significant dental anxiety is 19.

8. Prevalence of dental anxiety • 51% who had attended the a dentist had an MDAS score between 5-9 (indicating low/no anxiety) • 36% had an MDAS score between 10-18 (moderate anxiety) • 12% had a score of 19 or more (extreme anxiety)

9. Social Variation • Social variation: extreme dental anxiety • 15% routine and manual occupations • 12% intermediate occupations • 10% professional • Variation was across all dimensions for the MDAS scale.

10. Modified Dental Anxiety Scale: Prevalence against Gender

11. Percentage reporting very/extremely anxious by sex

12. 15% Anxiety: Percentage with 19 or over against age 6%

13. Modified dental anxiety scale by self-assessed general and dental health • General Health • Dental Health

15. Dental Anxiety and Oral health status • People with teeth are more anxious than those without! • Oral health • Fewer treatment experiences

16. Relationship with dentist at last visit

17. Conclusion • Barriers • Confounding issues between: Access, Cost and anxiety • Anxiety is a serious issue • Prevalence is high – particularly in women • Further Research • Age • Social variation • Gender
