Fluoride has a crucial role in prevention of dental caries, and its deficiency may initiate some dental problems. Conversely, excessive exposure to fluoride may lead to a number of adverse effects, ranging from mild dental fluorosis to crippling skeletal fluorosis. As drinking water and beverages are usually the main source of fluoride intakes, then the level of fluoride in these sources could have a significant effect on the dental health of the individual. The aims of this study were: (1) to determine the fluoride content in bottled waters, fruit juices, carbonated soft drinks, non-alcoholic beers and 1% w/v tea infusion that were commonly consumed by Iraqis and (2) to correlate the average daily intake of fluoride by 11-13 year old Iraqi schoolchildren with dental caries, experience, prevalence and severity. This study was carried out in 2013 on 1183, 11-13 years old elementary school children, which were randomly selected in Babil, Iraq. Clinical examinations for caries were conducted by two examiners using WHO criteria. Several kinds of beverages of 132 commercial brands purchased from supermarkets and groceries stores were analyzed. The fluoride content of all samples was determined in triplicate, using a Fluoride Ion Selective Electrode. Data was analyzed using SPSS software, the Chi-square test and analysis of variance (ANOVA). The results indicated that the mean DMFT index (Decayed, Missing, or Filled Permanent Teeth) of 11-13 year old Iraqi schoolchildren was 1.68 and that the average fluoride content in drinking water and beverages (< 0.50 mg/L) was too low for caries prevention. This DMFT rate is relatively high and can be reduced further to achieve the World Health Organization aim of less than one in the Eastern Mediterranean Region. In order to improve the oral health status of young Iraqi people and to achieve the WHO goals for oral health, the Iraqi health authorities had to focus more care on the preventive oral health programme. One of the most recommended prevention technique is water fluoridation. Water fluoridation is effective at reducing caries and has been hailed as one of the 10 greatest achievements in public health in the 20th century).
