Insights

Preterm birth significantly impacts oral development, leading to high rates of enamel hypoplasia and delayed dental development in affected children. These oral health issues require specialized dental management strategies.

Area of Science:

  • Pediatric Dentistry
  • Neonatal Medicine
  • Developmental Biology

Background:

  • Preterm and low birthweight infants face increased risks of neonatal complications.
  • These complications can adversely affect the development of oral tissues and dentition.
  • A decade of research reviews oral development in preterm children.

Purpose of the Study:

  • To review oral development in preterm children.
  • To correlate findings with current understanding of the field.
  • To highlight implications for dental management.

Main Methods:

  • Review of a decade of the author's research on preterm children's oral development.
  • Analysis of existing literature on the subject.
  • Clinical observation and data compilation.

Main Results:

  • High prevalence (40-70%) of generalized enamel hypoplasia in primary dentition of preterm children, linked to low bone mineral stores.
  • Increased incidence of localized enamel hypoplasia, crown dilacerations, and palatal distortions, often due to neonatal interventions.
  • Delayed dental development and eruption rates observed, particularly in children with lower birthweight and shorter gestational ages.

Conclusions:

  • Preterm birth is associated with significant dental anomalies, including enamel defects and developmental delays.
  • Neonatal medical interventions can contribute to specific dental malformations.
  • Early and specialized dental care is crucial for managing the oral health of preterm children.

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
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...
Language Development01:22

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
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...
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,...
