Main Results
The prevalence of ECC was 47.5% and that of severe ECC was 34.8%. Multiple
log-binomial regression analyzes showed that preschool children who
did not have an annual dental checkup showed 1.7 and 1.8 times higher
prevalence ratios (PRs) for simple ECC and severe ECC, respectively,
regardless of additional adjustments. Children’s snack and soda consumption
more than two times a day was associated with increased PRs for both
simple and severe ECC (PRs = 1.2 to 1.3 and 1.6, respectively). Children
who ate snack and soda once a day also showed PR of 1.4 relative to those
who did not, after controlling for demographic confounders. No association
was noted between caregivers’ self-rated oral health and ECC in
most of the models they evaluated.
