O creme dental fluoretado (500 ppm F –) e o risco de fluorose dentária

Resumo (EN)

Introduction – The ingestion of fluoride in doses above the considered ideal range may cause dental fluorosis in individuals during tooth formation. This anomaly is normally associated with chronical ingestion of fluoride from different sources. Methods – The work comprehends a critical analysis developed through mathematical calculations based on physiological principles, considering a daily ingestion of the fluoride contained in drinking water, at concentrations from 0,1 to 0,7 ppm of fluoride ions, associated with the ingestion of toothpaste with 500 ppm by children at the ages of 2, 3 and 4 when brushing their teeth. Results – The work identifies the theoretical doses from the association of both sources of fluoride ions ingestion, concerning the analysed ages, and compares them to the doses considered as therapeutical. Conclusion – The work outlines that there is no potencial risks of dental fluorosis using dentifrice with 500 ppm F – and drinking water with concentrations of 0,1 to 0,7 ppm of fluoride ions on children at the ages of 2, 3 and 4 years.
