Abstract
Aim: To identify a possible association between the occurrence of dental caries and tooth erosion
and to correlate the dietary factor with an increased risk of dental caries. Methods: A crosssectional
study in a multistage random sample of 1,211, 8 to 12-years-old Brazilian schoolchildren
in private and public schools was conducted in Pelotas, Brazil. The prevalence of dental caries
and tooth erosion was assessed. Dietary habits data were collected by a structured questionnaire.
Data were analyzed using Poisson regression model taking into account the cluster sample
(Prevalence ratio - PR; 95% Confidence Interval - CI). Results: The prevalence of dental
caries and tooth erosion was 32.4% (95% CI: 30.0; 35.2) and 25.0% (95% CI: 23.4; 29.0),
respectively. Most children had high consumption of sweets (65%). Consumption of fruits, such as
oranges (31%), strawberries (23.6%), pineapple (12%), and natural fruit juices (oranges,
lemon) was low. Soft drinks consumption, 3 or more times a week was observed in 40% of the
children. Conclusions: Dental caries was not statistically associated with tooth erosion. The
consumption of acidic fruits/drinks was not associated with dental caries. Dental caries and dental
erosion were not associated with each other and with acidic fruits or drinks consumption.
