RESUMO
OBJECTIVE: The aim of this study was to investigate oral and maxillofacial outcomes in children with congenital Zika syndrome (CZS) and the presence of nonnutritive sucking habits, functional habits, and features related to breastfeeding and nutrition of these children. STUDY DESIGN: We conducted a cross-sectional study with 45 children with CZS and 50 healthy controls in Sergipe state, Brazil, from February 2018 to June 2018. Demographic and clinical data, including breastfeeding and feeding data, were obtained for each child. Additionally, oral and maxillofacial evaluation was performed. RESULTS: Low weight (prevalence rate [PR] 8.33; 95% confidence interval [CI] 2.02-34.45), nonexclusive breastfeeding up to 6 months (PR 1.56; 95% CI 1.18-2.08); mouth breathing (PR 3.46; 95% CI 1.83-6.52); difficulty in swallowing (PR 6.00; 95% CI 2.53-14.25); and excessive salivation (PR 4.81; 95% CI 2.18-10.62) were more frequent in children with CZS. Children with CZS were more likely to have abnormal insertion of the upper labial frenulum (PR 7.04; 95% CI 2.23-22.20); ogival palate (PR 3.70; 95% CI 1.63-8.40), dental enamel defects (PR 2.22; 95% CI 1.05-4.69); and delayed dental eruption (PR 8.89; 95% CI 1.16-68.32) compared with healthy children. CONCLUSIONS: Children with CZS had a higher frequency of problems related to breastfeeding, low weight, and oral and maxillofacial abnormalities compared with healthy children.
