title: Perinatal outcomes and changes in the oral cavity: Brazilian cohorts of Ribeirão Preto and São Luís.
abstract: Studies have shown a possible association of oral diseases during pregnancy with preterm birth (PTB) and low birth weight (LBW). These perinatal outcomes appear to be associated with enamel defects in the primary dentition, which, in turn, seem to predispose to future development of caries in children. Therefore it is relevant to include oral health variables of the mother/child dyad in cohort studies to understand how these factors are associated. The objectives of this study are: 1) check if there is an association between diseases of the oral cavity of pregnant women and PTB, 2) test the hypothesis of association between perinatal outcomes and enamel defects/dental caries in children, 3) examine whether there are associations between perinatal outcomes and disorders of tooth eruption in children; 4) build theoretical models to study social inequities as a common factor between oral conditions and perinatal outcomes. We used an integrated, collaborative approach between two Brazilian cities with contrasting socioeconomic conditions: Sao Luis , MA, and Ribeirão Preto, SP - British Birth Cohort Studies study (BRISA Ribeirão Preto, São Luís). Two cohorts were evaluated: one initiated at birth, representative of the population of live births, and another, initiated prenatally. Participants were reassessed from the beginning of the second year of life. It is expected that these cohorts will contribute to foster the development and consolidation of population-based follow-up studies in Brazil.
