Prevalence of dental anxiety among 5- to 8-year-old Taiwanese children

OBJECTIVES: Many people experience discomfort to a greater or lesser degree about the prospect of dental treatment. Dental treatment can be a terrible experience, especially for children with dental anxiety. This study estimated the prevalence of dental anxiety among 5- to 8-year-old children in Kaohsiung City, Taiwan. METHODS: The Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) was translated into Chinese, and a receiver operating characteristic (ROC) curve was made based on criteria determined from pretest clinical observations of a sample population to set a cutoff score. Then, the parental CFSS-DS was used as a screening tool to survey the dental anxiety levels of 5- to 8-year-old children at kindergartens and elementary schools in Kaohsiung City, Taiwan. Participants were selected by stratified random sampling. The stratification was done by geographic district, age group, and sex. A total of 3,597 valid questionnaires were collected. RESULTS: The Chinese version of the CFSS-DS had an optimal cutoff score of 38/39 (sensitivity was 0.857, specificity was 0.882) with an area under the ROC curve of 0.912. The estimated prevalence of dental anxiety among 5- to 8-year-old children in Kaohsiung City was 20.6 percent. The dental anxiety score was found to decrease as age increased; primary school boys had significantly lower scores. CONCLUSIONS: The prevalence of dental anxiety was found to be high for 5- to 8-year-old Taiwanese children. The study's findings point to the urgent need for preventive health education and intervention programs in Taiwan to promote children's oral health and reduce dental anxiety.
