Elevated levels of fluoride in drinking water is a well-recognized risk factor of dental fluorosis. In this study, published in the journal Science of the Total Environment, authors found flouride to be strongly associated with dental fluorosis in a sample of over 1000 individuals living in several rural communities in the Ethiopia. Age, sex, SSSF, and milk consumption were found to correlate with dental fluorosis outcomes, both as independent factors and through modification of the effects of flouride. In addition, several other elements in water were significantly associated with dental health in the study area, suggesting the possibility that dental fluorosis may be related to multiple contaminant exposures. Additional research is warranted to more effectively isolate these effects, and to understand the mechanisms by which they operate.
