Resumo


This study aimed to classify the different types of insertion of the upper labial frenulum and their association with breastfeeding. It was a cross-sectional survey conducted from September 2020 to July 2022, involving 616 mother-infant pairs, with infants aged 0 to 12 months, participating in the Preventive Program for Pregnant Women and Babies extension project. The anatomical and morphological characteristics of the upper labial frenulum and the type of breastfeeding were examined. A Poisson regression model was applied to assess the association between the insertion of the upper labial frenulum and breastfeeding, with adjustment covariates selected using a Directed Acyclic Graph. The most common frenulum insertion was on the attached gingiva (65.2%), followed by the palatal surface (14%) and near the mucogingival junction (20.8%). Regarding breastfeeding, 70.8% of infants were exclusively breastfed (EBF), 17% predominantly breastfed (PBF), 1.8% received complementary feeding (CBF), and 0.5% were not breastfed. After adjustment, no significant association was found between the upper labial frenulum with palatal insertion and EBF (Prevalence Ratio 1.07; 95% Confidence Interval: 0.93-1.23). The findings suggest that infants with a maxillary labial frenulum insertion extending to the palatal face did not show any association indicating a negative impact on breastfeeding.
