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) 3

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 4

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) 5

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. 7
