The levels of, and relationships between, dental fear and general fears and phobias were studied in 109 adult patients at a specialized dental fear clinic using two dental fear scales (the Dental Anxiety Scale and the Dental Fear Survey) together with the Fear Survey Schedule II (FSS-II) and some additional fear items. Referred and self-referred fearful dental patients answered mailed questionnaires in conjunction to being put on a 1 yr waiting list for treatment. Among feared objects and situations the separate item 'pain' revealed the highest mean scores for both men and women, followed by fear of suffocating, death of a loved one and sharp objects among women, and death of a loved one, suffocating and hypodermic needles among men. With few exceptions, women scored higher than men. The frequencies of extreme fears (6 and 7 on a 7-point scale) were high and 92.7% of the patients reported at least one extreme fear. Half of the subjects (49.5%) reported five fears or more. It was also shown that a number of FSS-II items correlated to dental fear indicating a relationship between general and dental fear. These results indicated that a large proportion of these dentally fearful individuals were prone to fear-associated reactions and behaviors, which has previously been shown to negatively influence the prognosis of treatment.
