Insights

Developmental defects of dental enamel affect 44% of six-year-olds in southern Brazil. Factors like late pregnancy and lower maternal education are linked to these enamel defects, particularly demarcated opacities.

Area of Science:

  • Pediatric Dentistry
  • Public Health
  • Dental Enamel Development

Background:

  • Developmental defects of enamel (DDE) are common dental issues.
  • Understanding risk factors is crucial for prevention strategies.

Purpose of the Study:

  • To determine the prevalence of DDE in six-year-old schoolchildren.
  • To investigate associations between DDE and prenatal, neonatal, and postnatal conditions.

Main Methods:

  • Cross-sectional study of 655 six-year-old children in southern Brazil.
  • Data collection via maternal interviews and oral examinations.
  • Multivariate Poisson regression with robust estimator for analysis.

Main Results:

  • Overall DDE prevalence was 44.0%.
  • Demarcated opacities were the most frequent type, followed by diffuse opacities.
  • Independent associations found for demarcated opacities with late pregnancy, maternal schooling <8 years, female gender, and white skin color.

Conclusions:

  • A significant prevalence of DDE (44.0%) was observed in the study population.
  • Specific maternal and child characteristics are associated with DDE, highlighting potential risk factors.

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...

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...

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...

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
