Based on this study results, routine consumption of the tested locally produced bottled drinking water by infants and children provides adequate prevention against dental caries. More studies will be required to evaluate the fluoride content of the baby formulas that have been shown to contain variable amounts of fluoride for accurate estimation of fluoride intake by babies. Elevated level of fluoride in a child’s drinking water could result in fluorosis. While none of the tested bottled drinking water contain more than 1 mg/L fluoride, though extremely high fluoride concentration in bottled drinking water has been reported. Studies that assessed the fluoride level in main drinking water in different provinces in Saudi Arabai have shown that fluoride level vary widely between 0.00 and 6.20 ppm, and the populations living in these regions are not always exposed to adequate fluoride levels. The current analysis of locally produced bottled water indicates that the use of these products supplies more optimum and consistent amount of systemic fluoride compared to the more varying municipal network water and well water.
Most of the tested samples displayed the fluoride content of the water on the labels. Only two imported brands did nit list the fluoride content. This was not the case for many of the products tested in other countries. For example, Ahiropoulos studying water products in Greece, found that only 18% displayed the content of fluoride, and in Toumba et al. study,only 58% of the bottle waters stated the fluoride concentration on the label. Our findings indicated that eight out of the 13 samples evaluated showed a similarity between the measured fluoride content and that marked on the label. However, five samples showed a significant difference between our evaluation and stated content of fluoride that ranged between +0.46 and -0.2 mg/L. Dentists should be aware that values on the label might not be reliable when considering fluoride supplementation for children. In addition, quality control needs more close supervision on the part of drinking water factories to monitor the content of fluoride and other minerals and to accurately label their products.
