What does this research mean for the field?

Molar-incisor hypomineralization (MIH) has a high prevalence (21.2%) among Brazilian schoolchildren aged 7 to 10, and admission to a neonatal intensive care unit (NICU) is significantly associated with a more than twofold increased likelihood of developing the condition. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the prevalence of molar–incisor hypomineralization (MIH) and identify associated pre-, peri-, and postnatal factors among school-aged children.

Implication

Cross-sectional study reveals neonatal intensive care admission correlates with molar–incisor hypomineralization in schoolchildren, highlighting early-life health risks for tooth enamel development.

Key Points

To assess the prevalence of molar–incisor hypomineralization (MIH) and identify associated pre-, peri-, and postnatal factors among school-aged children.
Conducted a representative cross-sectional survey in Diamantina, Brazil, evaluating a random sample of 316 schoolchildren aged 7 to 10 years (80.8% response rate).
Diagnosed MIH using European Academy of Pediatric Dentistry (EAPD) criteria and collected sociodemographic and health history via caregiver questionnaires.
Analyzed associations using sample-weighted unadjusted and adjusted Poisson regression models.
The overall prevalence of molar–incisor hypomineralization among the evaluated schoolchildren was 21.2%.
Admission to a neonatal intensive care unit (NICU) was significantly associated with higher MIH occurrence in the adjusted model (prevalence ratio = 2.28, 95% CI: 1.34–3.90).
