ABSTRACT
A cross-sectional survey was undertaken in 1987 to measure the difference in caries experience in schoolchildren between a fluoridated (0.8 mg/L F-) and a non-fluoridated region (0.1-0.4 mg/L F-). 3436 children aged 5-15 yr were examined. Children in the non-fluoridated region had a higher caries experience than those in the fluoridated region. Mean differences were 1.06 dfs (95% CI = 0.66 to 1.47, P less than 0.001) and 0.48 DFS (95% CI = 0.23 to 0.72, P less than 0.001). After adjusting for potential confounding factors (fluoride tablet consumption, socioeconomic status, number of fissure-sealed surfaces, and mobility between regions) the relative risk of not being caries-free in the non-fluoridated region compared with the fluoridated region was 1.43 (95% CI = 1.21-1.70, P less than 0.0001) for the primary dentition and 1.39 (95% CI = 1.18-1.63, P less than 0.0001) for the permanent dentition.

In a comparison of caries of the incisor teeth of ten year old children living in a fluoridated area and those living in a non-fluoridated area, the prevalence of proximal lesions was found to be low (three teeth per 100 children) in the fluoridated area.

The caries experience of children aged six, eight, and ten years, examined in Perth after ten years of fluoridation was less than half that of children examined before fluoridation. In a concurrent survey, the caries experience of children examined in two unfluoridated towns was double that of the Perth children.

The Kalgoorlie-Boulder-Kambalda area in arid inland Western Australia receives its water supply from distant Perth, through a pipeline constructed in the fabulous goldrush period at the turn of the century. This water was fluoridated at the source in 1968. Comparison of dental data obtained by examination of goldfields schoolchildren before and after 6 years of fluoridation shows improved dental health through reduced caries rates, less tooth loss, and a change in the pattern of child dental care.
