BACKGROUND: Dental fluorosis is a dental tissue disease, characterized by hypomineralization resulting from excess fluoride reaching the developing tooth. In Mexico in recent years, the prevalence of fluorosis has increased by the exposure to different fluoridated sources such as those found in soft drinks and beverages. Our objective was to determine the prevalence of dental fluorosis among school children living in Nezahualcoyotl, state of Mexico and identify associated risk factors. METHODS: We conducted a cross-sectional study among 455 children aged 6-13 years who had been assessed by a previously standardized observer following WHO criteria. We administered The Community Fluorosis index (FCI) and a survey that analyzed the exposure to fluorides hidden in carbonated drinks, juices, bottled water, tea and the use of fluoride toothpastes. RESULTS: The prevalence of dental fluorosis was 73.4%. Very mild and mild fluorosis were the more common levels. The Community Fluorosis index (ICF) was 1.18 +/- 0.80. School children living at Nezahualcoyotl that answered they did drink hidden fluorides>0.71 ppm thought bottled beverages were more of a risk to develop dental fluorosis (RM 1,554, 95% CI 1.016-2.378, p<0.05). CONCLUSIONS: Dental fluorosis results from fluoride intake by different sources, however our study, consumption of fluoride hidden in soft and bottled drinks showed a significant correlation with observed fluorosis.
