Association between the number of early carious lesions and diet in children with a high prevalence of caries

ABSTRACT

Aim

An investigation was conducted in a population of paediatric patients with a high risk of caries in order to assess the
association between caries history (CH) and the number of early carious lesions (ECLs) and the frequency and timing of cariogenic
food and beverage intake, sugar-containing medication, the frequency and efficacy of tooth brushing, and the use of topical fluorides.
MATERIALS AND METHODS Study design: descriptive study. One hundred children aged 6-15 years with ECL of a permanent
tooth and not enrolled in any dental health educational or preventive programme were selected. For diagnosis it was used an explorer
according to the ICDAS II criteria. The participants completed a closed-list questionnaire on the frequency and timing of cariogenic food
intake. RESULTS There was a nonsignificant tendency to present more ECLs and a greater CH among patients who consumed
cariogenic foods and beverages. A significant relationship (p<0.05) was observed between cariogenic beverages and the number of ECL or CH. Using the number of ECLs as dependent variable, regular fluoridated rinses (p0.003), frequent sugar-containing medication (p0.007), and cariogenic beverage consumption (p0.024) were identified as explanatory parameters in the linear regression model. Statistic:s The Student t-test was used to compare ECL and CH with dietetic factors, fluoridated rinses, sugar- containing medicines, and the frequency and efficacy of tooth brushing. Linear regression analysis correlated the number of ECLs to the mentioned explanatory variables.

Conclusion

The frequent consumption of sugary beverages and medications, and failure to
regularly use fluoridated rinses, were positively correlated to an increased number of ECLs in patients with a high prevalence of
caries.
