Insights

Infant feeding patterns and growth metrics significantly influence teething timelines. Lower growth percentiles and early cow's milk or formula feeding can delay the eruption of the first tooth.

Area of Science:

  • Pediatrics
  • Human Growth and Development

Background:

  • Teething is a natural developmental milestone in infants.
  • The timing of teething varies considerably among healthy infants.

Purpose of the Study:

  • To investigate the impact of infant feeding patterns and growth parameters on the timing of tooth eruption.
  • To identify factors influencing the age at which the first tooth appears.

Main Methods:

  • A cohort of 1200 healthy term infants was monitored in a well-child clinic.
  • Data collected included infant growth parameters, feeding patterns (breast milk, cow's milk, formula), and the timing of first tooth eruption.
  • Logistic regression analysis was used to determine factors affecting teething time.

Main Results:

  • First tooth eruption occurred between 4 and 13 months of age.
  • By 6 months, 24.3% of infants had erupted teeth; by 9 months, 84.5% had at least one tooth.
  • Lower height-adjusted weight/height percentiles and early introduction of cow's milk or formula were associated with delayed teething by 6 and 9 months.

Conclusions:

  • Infant growth parameters and feeding practices are significant determinants of teething timing.
  • These factors may influence the developmental process of tooth eruption in healthy infants.

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,...
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 and...
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 grinding food.
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
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 the skin...
