This study aimed to characterize the profile of dental anxiety in pediatric patients, identifying the effect exerted by socioeconomic factors using dental data. A cross-sectional study design with a sample of 120 children aged 7-12 years old was used. Data relating to anxiety levels prior to dental care, socioeconomic aspects (family income, education level, child's school type), and child's dental history (previous dental appointments, previous treatment, caries experience) were collected. Additionally, participants completed the Brazilian version of the Children's Fear Survey Schedule- Dental Subscale (B-CFSS-DS) to assess dental anxiety. Descriptive analyses, chi-squared (X 2 ) tests, and Mann-Whitney U tests were performed, with a significance level of 5%. A total of 51 boys (42.5%) and 69 girls (57.5%) were included. There was no significant difference in dental anxiety between them. However, younger children had higher mean B-CFSS-DS scores (p = 0.036, Mann-Whitney). A higher prevalence of dental anxiety was found in participants from low-income families (p = 0.012, X 2 ) and in patients who did not receive endodontic treatment (p=0.034, X 2 ). Higher mean B-CFSS-DS scores were also observed in participants who did not receive endodontic treatment (p=0.001, Mann-Whitney) compared with those that did receive endodontic treatment. No relationship was found between education level, patient school type, first dental appointment, caries experience, and dental anxiety data. Younger children presented a profile of greater dental anxiety. Socioeconomic factors and dental data exerted some effect on dental anxiety, where children from low-income families and those not subjected to endodontic treatment displayed higher rates of dental anxiety.
