Avaliação da concentração de flúor e do consumo de água mineral

Abstract

ObjectiveConsidering that water is an importance source of fluoride intake, and that the consumption of mineral water and prevalence of dental fluorosis have been increasing, the aim of this study was to evaluate the consumption of mineral water and its fluoride concentration. Methods

Analysis of fluoride concentration in commercial bottled waters

“…Thus, it has become a public health concern in terms of the low fluoride content in most of the waters investigated. The fluoride concentration values found varied significantly within the range 0.07-0.63 ppm F -or mg F/L, which is similar to the findings of Brandão & Valsecki 1 , Ramires et al 14 and Grec et al 15 .…”

“…Corroborating the results reported by Ramires et al 14 , there was no significant variations in fluoride concentration in the same brand, as seen in brands # 3 and # 4. However, in different batches, there were differences in the fluoride content in the same brand.…”

“…In 2004, Ramires et al 14 conducted a study in the municipality of Bauru (SP) and also found great differences between the fluoride measured concentrations and those listed on the labels, as well as concentrations lower than those recommended by the National Health Surveillance Agency.…”

“…The increased consumption of bottled mineral water, mainly in the tropical area of the country, either as an alternative or as a supplement to the public water supply, can affect the safety and effectiveness of fluoridation thus posing risk to human health 1,[11][12][13][14][15] . Bottled mineral water is one of the sources of ingested fluoride and is considered a health promotion strategy, especially in terms of formation of dental tissues.…”

Conhecimento dos médicos pediatras e odontopediatras de Bauru e Marília a respeito de flúor

“…A utilização cada vez maior das águas engarrafadas faz com que estas se tornem importantes fontes de ingestão sistêmica de flúor, podendo desta forma ser consideradas como fator de risco para fluorose, principalmente quando empregadas no preparo de alimentos para crianças (leites e outros). Embora as águas engarrafadas sejam amplamente comercializadas no Brasil, sua concentração de flúor apresenta grandes variações e diferenças significativas em relação às informações no rótulo (Buzalaf et al 16 , Bastos et al 27 , Ramires et al 28 ).…”
