Purpose: Morocco is an endemic country of fluorosis, classically fluorine-rich areas are modeled on phosphate areas. Having recently observed cases of fluorosis in regions not known to have phosphate areas , the objective of our study was to define the prevalence and etiology of dental fluorosis in populations living in these areas.
Material and
Methods: this is an analytical cross-sectional study, including 2750 Moroccan schoolchildren aged between 3 and 12 years, living in regions where outbreaks of fluorosis had been observed. The prevalence and index of fluorosis according to age, consumption and source of water, consumption of tea and fish as well as the fluoride content of well water were studied.
Results: the lowest prevalence and fluorosis index were found in Rabat with 27% and 0.51 respectively. On the other hand, a higher prevalence was found in Er-Rachidia and Bouarfa 99% with a fluorosis index of 3.53 in Er-Rachidia and 3.11 in Guelmim, mainly in children aged 6 to 12 and over, who consumed 2liters per day of water. All regions had a higher consumption of 6 glasses of tea per day.
Conclusion: There are several fluorosis areas not known, whose main etiology would be the consumption of well water and the high consumption of tea with certain associated cofactors (fish, climates), thus the mapping of the Fluorosis in Morocco does not only concern phosphate zones
