Insights

Children with microcephaly experience significant delays in tooth eruption and more anomalies, including enamel defects and altered eruption sequences, compared to typically developing children. This highlights potential oral health challenges for this population.

Area of Science:

  • Pediatric Dentistry
  • Public Health
  • Developmental Pediatrics

Background:

  • The 2015-2017 microcephaly outbreak in Brazil posed a significant public health challenge.
  • Understanding the developmental impacts of microcephaly is crucial for affected children.

Purpose of the Study:

  • To compare tooth eruption patterns and anomalies in children with microcephaly versus those without.
  • To evaluate the chronology and sequence of dental development in microcephalic infants and toddlers.

Main Methods:

  • A matched-pair comparative study involving 108 children (0-2 years).
  • 54 children with microcephaly (MG) and 54 without (NMG), matched for age, gender, and income.
  • Evaluation of erupted teeth, eruption sequence, and anomalies using statistical tests (Chi-square, t-tests, etc.).

Main Results:

  • Microcephalic children showed significantly higher rates of altered eruption sequence (OR=12.23).
  • Delayed tooth eruption was markedly more prevalent in the microcephaly group (OR=23.12).
  • Enamel opacity and self-injury were also more frequent in children with microcephaly (P<0.05).

Conclusions:

  • Children with microcephaly exhibit delayed tooth eruption chronology and sequence anomalies.
  • Enamel defects are more common in children diagnosed with microcephaly.
  • These findings underscore the need for specialized dental monitoring in microcephalic children.

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...

Alterations in Respiration II01:30

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Altered States of Awareness01:06

Altered States of Awareness

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Comparative Excretory Systems

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
