Fluoride concentration of bottled water, tap water, and fluoridated salt from two communities in Mexico

Abstract

Some water samples had amounts of fluoride exceeding the maximum recommended levels. Salt fluoride levels were within regulation limits. Monitoring of fluoride content of both bottled and tap water is strongly advised.

Caries prevalence and its association with brushing habits, water availability, and the intake of sugared beverages

“…In our study, we did not collect water samples to analyse them for fluoride. Previous studies in this community have indicated that the fluoride content of bottled water varies widely from negligible to above optimal, whereas tap water in this community contains negligible amounts of fluoride 15,31 .…”

Effect of body weight and behavioural factors on caries severity in Mexican rural and urban adolescents

“…The reported fluoride concentration in drinking water in the two areas was well under the recommended level of <0.7 mg/L (0.24 mg/L in the rural area and 0.15 mg/L in the urban area).…”

Distance from source and fluoride concentrations in municipal water supply

“…All of the data from Houston, Los Angeles, and New Hampshire, USA, and Mexico and Brazil indicate the difficulty is maintaining consistent levels. One explanation why the levels might fluctuate is due to fluoride reacting with other dissolved chemicals in the water.…”

“…A study of two communities in Mexico showed that tap water samples that were analyzed had a significant difference, with some water samples exceeding maximum recommended levels. Martinez‐Mier et al . concluded that monitoring the fluoride content of both bottled and tap water is strongly advised.…”
