Insights

Breast-feeding and delaying solid food introduction in infants are linked to increased early childhood caries. Mixed feeding, however, showed a reduced risk of dental caries compared to breast-feeding alone.

Area of Science:

  • Pediatric Dentistry
  • Public Health Nutrition
  • Epidemiology

Background:

  • Early childhood caries (ECC) is a significant public health concern.
  • Feeding practices are recognized as potential risk factors for ECC.
  • Understanding these associations is crucial for developing preventive strategies.

Purpose of the Study:

  • To examine the relationship between infant feeding methods and the prevalence of early childhood caries.
  • To analyze data from a representative Korean national survey to identify risk factors for ECC.

Main Methods:

  • Analysis of data from 2772 children aged 1-3 years from the Korean National Health and Nutrition Examination Surveys (2007-2018).
  • Assessment of early childhood caries based on decayed-filled teeth (dft) values (dft ≥1).
  • Logistic regression models were used to determine the association between feeding practices and ECC, controlling for relevant variables.

Main Results:

  • The breast-feeding group exhibited the highest mean dft values.
  • Mixed feeding was associated with a significantly lower likelihood of ECC compared to breast-feeding.
  • Delayed introduction of weaning foods (≥6 months) was linked to a higher likelihood of ECC.

Conclusions:

  • Breast-feeding and late introduction of weaning foods are associated with an increased risk of early childhood caries.
  • Mixed feeding may offer a protective effect against early childhood caries.
  • These findings highlight the importance of tailored infant feeding recommendations for oral health.

Tooth Anatomy01:21

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

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...

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

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...
