Ibiyemi O, et al. - The researchers performed this work to determine the prevalence and extent of developmental enamel defects (DDE) and dental fluorosis in 8-year-old Nigerians and examined relationships with key predictors. Results revealed that mouth prevalence of DDE was 61.2% and a key positive predictor was a history of infant/childhood disease in these Nigerian 8-year-olds. With 29.8% of these children exhibiting dental fluorosis, drinking water F concentration was detected as a positive predictor, along with gender, with females more at risk of dental fluorosis than males.
