Use of Dental Care Among Pregnant Women in the Brazilian Unified Health System

Purpose: To assess the prevalence of and factors associated with the use of public Unified Health System-based dental services by pregnant women and recent mothers. Materials and Methods: In this cross-sectional study, face to face interviews were conducted to collect data on the outcome of interest (prevalence of use of dental care) and independent variables (sociodemographic, pregnancy, and prenatal care data). A total of 302 pregnant women seen at public dental services in the municipality of Canoas, southern Brazil, were interviewed. Statistical analysis was performed using the chi-squared test and hierarchical Poisson regression with robust variance (p 0.05). Results: The prevalence of use of dental care among pregnant women was 50% (n = 151). Pregnant women who initiated prenatal care in the first trimester showed a 34% higher likelihood of using dental care (prevalence ratio [PR] 1.34; 95% confidence interval [95%CI] 1.27-1.61); this likelihood was 12% higher among multiparous women (PR 1.12; 95%CI 1.03-1.23), and 40% higher among women who received guidance to seek dental care (PR 1.40; 95%CI 1.30-1.51). Conclusion: The present findings suggest that starting prenatal care in the first trimester, being multiparous, and receiving guidance to seek dental care significantly contributed to the use of public dental services during pregnancy in the population assessed. These factors should be considered when planning public health policies for this population. Schlagwörter: access to health care, dental care, oral health, maternal and child health, pregnant women
