ABSTRACT
BACKGROUND:
Hypomineralized second primary molar (HSPM) is a developmental enamel defect that represents a caries-risk factor. There are few studies about HSPM epidemiology in representative populations.AIM:
To determine the prevalence and factors associated with HSPM in pre-schoolers.DESIGN:
This is a cross-sectional population-based study of 5-year-old pre-schoolers from Teresina, Brazil. The sample was randomly selected and stratified by geographic region of the city, type of school (public and private), and sex of the pre-schoolers (n = 811). Sociodemographic status and pre-, peri-, and post-natal conditions were collected by structured questionnaires. Two calibrated examiners diagnosed HSPM using the criteria of the European Academy of Paediatric Dentistry for molar-incisor hypomineralization. Severity, colour, location, and extent of lesions were also evaluated. Descriptive analysis of the data and a Poisson regression analysis were performed (P < .05).RESULTS:
The prevalence of HSPM was 14.9. Demarcated opacities (75.6%) and white/cream colour were the most prevalent (71.4%). Pre-term pre-schoolers had 66% (PR = 1.66, 95% CI = 1.07-2.58), and those who reported asthma in the first year of life had 69% (PR = 1.69, 95% CI = 1.01-2.85) higher prevalence of HSPM.CONCLUSIONS:
Pre-term birth and reported asthma in the first year of life were associated with HSPM. The prevalence of HSPM in pre-schoolers aged 5 years old in Teresina was high.Palabras clave
