Longer breast-feeding duration is linked to a lower risk of posterior crossbite in children. Exclusive breast-feeding for extended periods significantly reduces the likelihood of developing this dental issue.
Area of Science:
- Pediatric Dentistry
- Public Health Nutrition
Background:
- Posterior crossbite is a common dental malocclusion.
- Breast-feeding is recognized for its numerous health benefits for infants and children.
Purpose of the Study:
- To investigate the association between the duration of breast-feeding and the incidence of posterior crossbite in Brazilian children.
- To determine if exclusive breast-feeding duration impacts posterior crossbite occurrence.
Main Methods:
- A cross-sectional study involving 714 children aged 6-9 years.
- Mothers/guardians completed questionnaires on breast-feeding duration (exclusive and total).
- Clinical examinations assessed for posterior crossbite; data analyzed using Pearson's chi-square test.
Main Results:
- Posterior crossbite prevalence was approximately 15%.
- Prevalence was significantly higher in non-breast-fed children (28%) compared to breast-fed children (13%).
- A significant association was found between posterior crossbite and both exclusive and total breast-feeding duration (P<.05).
Conclusions:
- Increased exclusive breast-feeding duration correlates with a reduced prevalence of posterior crossbite.
- Breast-feeding duration is a significant factor influencing the development of posterior crossbite in children.
