title: Dental fear with and without blood-injection fear: implications for dental health and clinical practice.
abstract: The relation between dental, blood and injection fear and oral health was examined in 936 New Zealand 18-year-olds. Of the approximately ten percent (n = 96) of the sample who reported a dental fear, 1 in 10 also reported a fear of blood and 53% a co-morbid fear of injections. Study members with dental fear alone or co-morbid dental and blood or injection fear had significantly worse oral health (i.e. greater caries experience) than a no-fear comparison group or individuals with blood-injection fear only. Further, individuals with dental and blood or injection fear had a significantly higher level of recent tooth decay than individuals with dental fear alone. Time since last dental treatment also tended to be highest in this group. Implications for dental health and practice were discussed.
