The relationship between the fluoride content of the enamel and dentine of deciduous teeth and the number of tooth lesions/mouth was compared to fluoride treatment in Logan , Brigham City, Helper and Milford, Utah. Bone measurement data was obtained on the second metacarpal bones of the mother s of the participating children from the same communities except Brigham City.
The fluoride treatment in the communities were as follows: Logan has no fluoride added to the domestic water supply but some children received fluoride treatment through tablets, drops, etc. Milford has water which naturally contains 0 . 8 ppm fluoride , Helper and Brigham City have 1 ppm fluoride added to their water ,supplies.
The results showed that significantly less (P > 0.05) fluoride existed in the dentine of teeth originating from Logan children without fluoride treatment than the dentine from fluoride treated children in Logan and Brigham City. The fluoride content of the enamel showed a tendency to be increased with increasing amount of fluoride exposure. The fluoride content of the enamel and dentine from non fluoride treated Logan children was considerably less than from fluoride treated Logan children and from Brigham City children.
Logan children who had received fluoride treatments had significantly (P > 0.05) fewer dental lesions/mouth compared to the nontreated Logan children. The fluoride exposed Milford and Helper children had a greater frequency of dental lesions/mouth than even nonfluoride treated Logan children . This might be explained by the socioeconomic differences existing between Logan in comparison to Helper and Milford.
Midshaft bone measurements were taken on x-rays of the second metacarpal of women (average age 35.7) residing ten or more years in the respective community. When measuring cortical thickness, cortical area, medullary area, and per cent cortical area, no significant differences could be shown.
