Association between Obesity and Dental Caries in Chinese Children.

The study sought to analyze the association between dental caries and obesity in Chinese children, and to investigate the protective and risk factors of dental caries. A total of 280 children aged 7-12 years voluntarily answered the caries examination and questionnaire. Caries was measured using the International Caries Detection and Assessment System. According to the Chinese body mass index, the participants were grouped overweight or normal-weight. The logistic regression model showed no correlation between dental caries and obesity. Drinking yogurt and chewing gum are protective factors, whereas oral breathing and genetic predisposition to caries are risk factors. Copyright © 2012 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
