title: Influence of clinical and socioeconomic indicators on dental trauma in preschool children.
abstract: The aim of the present study was to determine the prevalence of traumatic dental injury (TDI) in the primary dentition and investigate associations with clinical and socioeconomic indicators. A population-based, cross-sectional study was carried out with a randomly selected sample of 301 children aged one to five years. Data were collected through clinical oral examinations and interviews with parents/guardians during immunization campaigns. Statistical analysis involved Pearson's Chi-squared test and Poisson regression with robust variance. The prevalence of TDI was 33.9%. TDI was more prevalent in children with overjet > 3 mm (p < 0.001) and those with inadequate lip coverage (p < 0 .001). A statistically significant association was also found between TDI and household income (p = 0.024). According to the adjusted Poisson regression model, greater prevalence rates of TDI were found for children from families with a monthly income ≥ twice the Brazilian minimum monthly wage (PR: 1.52; 95%CI: 1.10-2.12), those with accentuated overjet (PR: 1.53; 95%CI: 1.05-2.22) and those with inadequate lip coverage (PR: 2.00; 95%CI: 1.41-2.84). The prevalence of TDI was high in the present study and was associated with a higher family income, accentuated overjet and inadequate lip coverage.
