Insights

Preterm (PT) and/or low birth weight (LBW) children exhibit more developmental enamel defects (DED) than full term (FT) infants. Neonatal intensive care unit admission is linked to DED, but dental caries rates are similar between groups.

Area of Science:

  • Pediatric Dentistry
  • Neonatal Health
  • Developmental Biology

Background:

  • Developmental enamel defects (DED) can impact oral health in children.
  • Preterm birth and low birth weight are associated with various health challenges.
  • Understanding DED prevalence in these groups is crucial for early intervention.

Purpose of the Study:

  • To compare DED and dental caries in preterm/low birth weight (PT/LBW) versus full term/normal birth weight (FT/NBW) children.
  • To investigate associations between DED and socioeconomic, gestational, and postnatal factors.

Main Methods:

  • Study included 84 children aged 2-5 years, matched for sex and age (1:1 ratio).
  • Groups comprised 42 PT/LBW children and 42 FT/NBW children.
  • Data analyzed using descriptive statistics, bivariate analysis, and Poisson regression.

Main Results:

  • PT/LBW children had significantly more teeth with DED compared to FT/NBW children.
  • No significant difference in dental caries prevalence was found between the groups.
  • Admission to the neonatal intensive care unit was significantly associated with DED (PR=0.21).

Conclusions:

  • PT/LBW children demonstrate a higher incidence of DED.
  • Dental caries rates do not differ significantly between PT/LBW and FT/NBW children.
  • Neonatal intensive care unit admission is a risk factor associated with DED in early childhood.

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...

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...

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...

Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
