摘要：Objective: Evaluate the prevalence of developmental defects of enamel (DDE) in permanent molars and its association with sociodemographic characteristics and systemic conditions in children treated at the paediatric dentistry clinic of private dental school. Material and Methods: The sample consisted of 706 medical records of children aged 8 to 12 years of both sexes, treated between 2004 and 2017. The inclusion criteria included the presence of the first 4 permanent molars, absence of syndromes related to enamel malformations and dentoalveolar trauma in the first 3 years of life and complete medical records. The dependent variable (hypomineralization/hypoplasia) and the independent variables (sociodemographic and health variables) were collected and evaluated using descriptive analysis, association tests (chi-square) and logistic regression, at a significance level of 5%. Results: The prevalence of DDE in the first permanent molars was 55.95%, with no association with sociodemographic characteristics. Conclusions: The association of DDE in the first 4 permanent molars with the independent variables such as caesarean, forceps or preterm delivery and systemic diseases until 3 years of age were statistically significant.
