Fluoride content of bottled drinking waters available in Riyadh, Saudi Arabia
Abstract Aims: This study aimed to examine the fluoride concentration of commercially available bottled water products in Riyadh, Saudi Arabia, and to assess the accuracy of the labeling of fluoride concentration on the tested brands.
Methods: Fifteen randomly selected commercial brands of bottled water were obtained from supermarkets in Riyadh, Saudi Arabia. Three bottles of each brand were purchased, and fluoride concentration was measured using a combination fluoride-ion-selective electrode. The average reading for each brand was estimated and also compared with the fluoride concentration
Printed on the lable.
Results: The mean fluoride concentration of the 12 local bottled water samples was 0.79 mg/L with a range from 0.5 to 0.83 mg/L. The mean fluoride concentration of the three imported brands was 0.67 mg/L with a narrow range of fluoride content. All tested samples mention the fluoride content on the label except two imported brands Five samples showed a significant difference between our evaluation and stated content of fluoride that ranged between +0.46 and -0.2 mg/L
Conclusions: Bottled drinking water available in Riyadh, Saudi Arabia contain differing concentration of fluoride, but within a safe range for use as a source of systemic fluoride. In addition ,the manufactures’ labeling of fluoride content may be inaccurate
1.Introduction
one of the most common trends among consumers in recent years in various countries, including Saudi Arabia, is the replacement of their daily water intake with bottled water, possibly due to apprehension about contaminants in natural water supplies. Sales of bottled water are available in Saudi Arabia supermarkets. The substitution of commercial drinking water with bottled water is a serious concern because the benefit of drinking fluoridated water may be lost. The dental caries reduction that derived from drinking fluoridated water is well documented and water fluoridation is considered an economical and safe preventive measure.
