内容記述タイプ Abstract
内容記述 Because Japanese water supply laws prohibit fluoridation for the purpose of reducing dental caries, few reports exist on the relation between mottled teeth and the levels of fluoride concentration in drinking water consumed by Japanese children during the period of enamel formation. The upper limit of natural fluoride in drinking water is legally established at 0.8ppm. This threshold has recently been questioned, however, by research which has found moderate mottling in the enamel of school children whose water supply is below the 0.8ppm limit. We have accordingly undertaken this research to determine whether the consumption, during the enamel formation period, of drinking water with fluoride concentrations at or below the legal threshold can cause mottling. The data come from a small village which was supplied for a six-year period with water containing natural fluoride levels of 0.6-0.7ppm. The average annual temperature for the village is 12℃. We have examined the teeth of school children of this village over an 18-year period, including the six years in which fluoridated water was supplied. Among school children who consumed this water either throughout the enamel formation period of the incisors, or during the second half of this period only, ten had a moderate degree of mottling of the enamel. Mottling was not as severe, however, in children who consumed this water during the first half of the enamel formation period only. We conclude from these results that the legal threshold needs to be lowered from its current level of 0.8ppm, as the current limit can not assure the prevention of mottled enamel due to fluoride in drinking water.
