Fluoride content in bottled waters, juices and carbonated soft drinks in Mexico City, Mexico

Abstract

The findings suggest that fluoride ingested through bottled drinks represents an important part of the total fluoride ingested by the population. In view of the wide variation of fluoride concentration in the tested products, it is necessary to implement regulatory guidelines for controlling its concentration in order to prevent dental fluorosis.

Erosive characteristics and fluoride content of cola-type drinks

“…Several studies have previously measured F ion concentrations of carbonated drinks, either in relation to measuring F exposure 27,28 , or in determining whether the F can mitigate against dental erosion 17,29 Although between-container differences in F ion concentration have been reported previously 28 , the present study found similar F ion concentrations for drinks sold in cans and in plastic bottles (median: 0.03 mg/L). While no significant difference was reported for F ion concentrations of drinks sold in glass and cans in the work by Heilman et al, 27 in the US, the F ion concentration of canned Mexican cola drinks was reported to be higher (0.74mg/L) than those drinks sold in plastic (0.37mg/L) and glass containers (0.34 mg/L) 28 .…”

“…While no significant difference was reported for F ion concentrations of drinks sold in glass and cans in the work by Heilman et al, 27 in the US, the F ion concentration of canned Mexican cola drinks was reported to be higher (0.74mg/L) than those drinks sold in plastic (0.37mg/L) and glass containers (0.34 mg/L) 28 . This may reflect the use of different containers in different parts of a country in which the F ion concentrations of the manufacturers' supply waters also differ.…”

“…In laboratories, F solutions are not normally stored in glass containers as F ion has an affinity for glass, reducing the F ion concentration of its contents 28 . Despite this high affinity of F ion for glass the median F ion concentration of Coca-Cola drinks in glass containers was higher (0.26 mg/L) compared with the 0.1mg/L found for Coca-Cola drinks in cans and plastic bottles, suggesting that higher F ion concentration waters may have been used for the production of these drinks.…”

Analysis of the molecular structure of human enamel with fluorosis using micro-Raman spectroscopy

“…As a result, teeth are more susceptible to the effects of normally occurring chemical and mechanical injuries (3,4). In addition, several studies have suggested that severe fluorosis might increase the susceptibility to dental caries (5)(6)(7).…”

Fluoride Concentration in Community Water and Bottled Drinking Water: A Dilemma Today

“…5,6 International studies supports the widely held view that the majority of bottled waters available contain negligible fluoride in terms of its dental health benefits. [7][8][9][10][11][12][13][14] From the available literature it was found that the data regarding fluoride concentration in community water and bottled drinking water sold in Faridabad city is lacking. With the assumption that the bottled water is being widely used nowadays, this study was undertaken in order to fill this lacuna.…”
