Insights

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.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

Teeth01:15

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...
