- Association between maternal cardiometabolic risk factors and oral health of infantsPublication . Pestana, Rebeca Saad; Baptista, Manuel; Magalhães, Inês; Morais, Juliana; Ferreira, Ana Filipa; Marques, Sofia Cameron; Jerónimo, Maria Luís; Pinto, Carla; Sousa, Marta; Falcão-Pires, Inês; Duister, Denise; Zaura, Egija; Azevedo, Maria João; Maia, Benedita SampaioMaternal health conditions during pregnancy influence infant health1-3. Cardiometabolic risk factors (CRFs), such as obesity, hypertension, and gestational diabetes, increase maternal and neonatal complications due to chronic inflammation, which disrupts immune and endocrine adaptation4,5. While the effects of CRFs on infant development are well studied, their impact on oral health remains unclear. Therefore, this study aims to assess the association between maternal CRFs and oral health of infants at three years of age. The prospective OralBioBorn cohort follows pregnant women (healthy and with CRFs) and their children up to 36 months postpartum. At age three, oral hygiene habits, caries experience using ICDAS, and Quigley-Hein plaque index (PI) of children were assessed. PI was evaluated on buccal and lingual surfaces. Preliminary data from 36 children (26 from healthy mothers, 10 from mothers with CRFs) showed no cavitated, missing, or filled teeth due to caries, nor PUFA Index lesions, in either group. The PI did not differ significantly between children of healthy mothers and those of mothers with CRFs (0.17±0.32 vs. 0.49±0.72, p>0.05, Mann-Whitney U test). The lack of associations between maternal CRFs and child oral health may reflect multiple factors, including the small sample size, the young age of the children, and the possibility that maternal CRFs do not exert a strong early influence on oral health. Future work will focus on evaluating a larger cohort and considering additional determinants, such as oral hygiene and dietary habits, which may play a more prominent role in shaping early oral health outcomes. This will provide a deeper understanding of potential mediating factors influencing early oral health trajectories
- Breastfeeding and malocclusions: Characterization of a pediatric dentistry population enrolled in a birth cohort studyPublication . Marques, Sofia Cameron; Baptista, Manuel; Magalhães, Inês; Morais, Juliana; Ferreira, Ana Filipa; Pestana, Rebeca; Jerónimo, Maria Luís; Pinto, Carla; Sousa, Marta; Pires, Inês Falcão; Deuster, Denise; Zaura, Egija; Areias, Cristina; Maia, Benedita SampaioBreastfeeding plays an important role in the development of the craniofacial complex (1,2). However, the role of breastfeeding duration, non-nutritive sucking habits, and the timing of solid food introduction on the development of malocclusions is still in debate (25). Therefore, this study aimed to investigate these associations in a birth cohort. In the ongoing OralBioBorn birth cohort, occlusion of three-year-old children was assessed in maxiumum intercuspidation, examining the left and right sides, followed by a frontal assessment. In addition, the information on breastfeeding type and duration, solid food introduction, and non-nutritive sucking habits was collected through a parental questionnaire. Preliminary data from 39 children revealed a high prevalence of open bite (33.3%), crossbite (20.5%), and overbite (10.3%). Scissor bite, high/narrow palate, and crowding were observed in only one child each. The relationship between these occlusal characteristics and breastfeeding duration, non-nutritive sucking habits, and solid food introduction will be further explored. The preliminary findings suggest that malocclusions are frequent at an early age, reinforcing the need to investigate their potential early-life determinants. Future work will involve a more in-depth analysis of the associations between occlusal development and early feeding practices, considering additional factors such as genetic predisposition and environmental influences. Longitudinal follow-up of this cohort will provide valuable insights into the long-term impact of breastfeeding and oral habits on craniofacial growth, ultimately contributing to early preventive strategies.
