Prevalence of dental anxiety in an adult population in a major urban area in Sweden.

The aims of the study were to describe the level of dental anxiety in a representative sample of an adult population, to evaluate different demographic variables in relation to dental anxiety, and to compare two measurement scales of dental anxiety. A random sample of residents (n = 830) of the city of Gothenburg (population 432,000) was selected for a telephone survey. The survey comprised different questions concerning demographic variables, dental care habits, and the level of dental anxiety. The methods of measurement of dental anxiety were a 10-point dental Fear Scale (FS) and the Corah Dental Anxiety Scale (DAS). A total of 620 interviews were completed giving a response rate of 74.7%. 41.4% of the respondents were males, 58.6% females. Females were significantly more likely to report a high dental anxiety compared with males. The prevalence of high dental anxiety in the sample as measured by the FS and DAS was 6.7% and 5.4% respectively. The correlation between the FS and DAS was 0.81. The distribution of high dental anxiety and age showed a clearly and significantly higher portion of dental anxiety in the age group 20-39 yr compared to both younger and older groups. The effect of dental anxiety on regularity of dental visits revealed a significant difference as measured by the FS. No significant correlation was found between dental anxiety and educational level or income. A majority of the respondents (82-95%) expressed a desire for establishment of a special dental fear treatment clinic without need for referral.
