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.
Background:
The outbreak of microcephaly between 2015 and 2017 in Brazil created an international public health emergency.
Aim:
This study sought to evaluate the chronology, sequence of eruption, and the presence of anomalies amongst children with microcephaly compared with normoreactive children.
Design:
A comparative study of 108 children aged 0-2 years attending public services was conducted. The microcephaly group (MG; n = 54) and the nonmicrocephaly group (NMG; n = 54) were matched by age, gender, and family income at a 1 : 1 ratio. Erupted teeth and the presence of anomalies were evaluated and compared. Chi-square tests, Pearson's correlations, Fisher's exact tests, and Student's t-tests were applied (α = 0.05).
Results:
No between-group differences were found with regard to gender (P = 0.560) or age (P = 0.529). The MG presented with a higher percentage of alterations in eruption sequence, opacity, self-injury, and delayed eruption compared with the NMG (P < 0.05). The MG was more likely to exhibit changes in tooth eruption sequence (OR = 12.23, 95% CIs = 3.25-46.03, P < 0.001), delayed eruption (OR = 23.12; 95% CIs = 7.09-75.40, P < 0.001), and opacity (n = 12.19, 95% CIs = 1.44-103.28, P = 0.022) than the NMG.
Conclusion:
Children with microcephaly present with greater delays in chronology, alterations in eruption sequence, and enamel defects than normoreactive children.
