Abstract

Objective To further understand the effect of anti-fluoride water on intellectual development of children and dental fluorosis in drinking water-type of endemic fluorosis area Pucheng county Shaanxi province.Methods Two hundred 8 to 12 years old children were randomly selected in endemic fluorosis area with changed water or unchanged water, in 2009 in Pucheng county Shaanxi province. Intelligence quotient(IQ) of children was measured by Raven's test. Children's dental fluorosis was examined by Dean's classification scheme. Results The rates of child dental fluorosis in changed water and unchanged water endemic fluorosis areas were 28.50%(57/200), 87.88%(203/231) , respectively, the difference was statistically significant(x2 = 159.19, P＜ 0.01),while dental fluorosis indices were 0.57,1.97, was marginal, moderate epidemic. Children with IQ above 90 was accounted for 89.5% (179/200), 91.5% (183/200) in changed water and unchanged water endemic fluorosis area,respectively, the difference was not significant (x2 = 0.46, P ＞ 0.05). Conclusions Changed water may decrease the incidence of child dental fluorosis, but has no obvious effect on children's IQ development in endemic fluorosis area. Key words: Drinking; Fluorosis,dental; Intelligence

陕西省浦城县地方性氟中毒病区饮水类型改变前后儿童智商与氟牙症调查

目的进一步了解抗氟水对陕西省蒲城县地方性氟中毒地区饮水型儿童智力发育及氟牙症的影响。方法2009年在陕西省蒲城县地氟病改水和不改水地区随机抽取8 ~ 12岁儿童200例。采用雷文测验法测定儿童的智商。采用Dean氏分级法对儿童氟牙症进行检查。结果变水和不变水地方性氟中毒区儿童氟斑牙患病率分别为28.50%(57/200)、87.88%(203/231)，差异有统计学意义(x2 = 159.19, P< 0.01)，而氟斑牙指数分别为0.57、1.97，为边缘性、中度流行。在变水和不变水地区，智商≥90的儿童分别占89.5%(179/200)和91.5%(183/200)，差异无统计学意义(x2 = 0.46, P > 0.05)。结论改水可降低儿童氟牙症发病率，但对地方性氟斑病地区儿童智商发育无明显影响。关键词:饮酒;牙氟中毒;情报
