Abstract
The use of bottled drinking water may be a source of fluoride and could
be a risk factor for fluorosis among infants and young children. The aim of this
study was to evaluate the fluoride content of commercially available bottled drinking
water in Bangkok, Thailand. Forty-five water samples (15 samples of plain
water and 30 samples of mineral water) were purchased from several supermarkets
in Bangkok, Thailand. Three bottles of each water sample were purchased,
and the fluoride content of each sample was measured twice using a combination
fluoride-ion selective electrode. The average reading for each sample was then
calculated. Data were analyzed by descriptive statistics. Differences between
mineral and plain water samples were determined by Student’s t-test. The mean
(±SD) fluoride content for all the water samples was 0.17 (±0.17) mg F/l (range:
0.01-0.89 mg F/l). Six brands (13%) tested stated the fluoride content on the label.
The actual fluoride content in each of their brands varied little from the label.
Eight samples (18%) had a fluoride content >0.3 mg F/l and two samples (4%)
had a fluoride content >0.6 mg F/l. The mean mineral water fluoride concentration
was significantly higher than the mean fluoride concentrat...
