Abstract
This cross-sectional study evaluated the prevalence of dental fear and associated factors in schoolchildren aged 8 to 12 years old, in Pelotas, southern Brazil. Schoolchildren enrolled in 20 public and private schools were selected using a multi-stage sample design. Sociodemographic characteristics, children's dental visit and oral hygiene habits were assessed by questionnaires. The Dental Anxiety Question was used to measure dental fear prevalence. Children's clinical examination evaluated presence of dental caries (DMFT/dmft index) and gingival bleeding. Data were analyzed using Poisson regression with robust variance (prevalence ratio; 95% confidence interval). One thousand two hundred and two children were included. Dental fear prevalence was 24.6%. After the adjustment, girls [PR=1.71 (CI 95%: 1.31-2.22)], children from poorer families [PR=1.96 (CI 95%: 1.36-2.83)], those who had decayed teeth (D/d index>0)[PR=1.32 (CI 95%: 1.01-1.72), and who had never been at the dentist [PR=1.85 (CI 95%: 1.42-2.41) remained significantly associated with dental fear. The prevalence of dental fear indicates that it is a common problem among schoolchildren. Early dental care and dental caries prevention are important factors to prevent dental fear.
