ORÍGENES DEL FLUORURO INGERIDO Y RIESGO DE FLUOROSIS DENTAL

Resumen

Although the predominant beneficial effects of fluoride occur locally in the mouth, the adverse effect, dental fluorosis, occurs by the systemic route. Caries incidence and prevalence has decreased significantly over the last two decades due to the widespread use of fluoride. However, simultaneously, an increase in the prevalence of dental fluorosis has been reported both in communities with fluoridated and non-fluoridated water. The increase in fluorosis prevalence prompted numerous studies on risk factors for fluorosis. This review describes the main sources of fluoride intake that have been identified until now: fluoridated drinking water, fluoride supplements, fluoride toothpaste, infant formulas and other manufactured infant foods and beverages. Recommendations on how to avoid excessive fluoride intake from these sources are also given.
