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)

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

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)

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
6
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
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)
8
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.
