阳原县王汉庄村采用活性氧化铝药物降氟改水,三年后8—12岁儿童氟斑牙检出率明显下降,由三年前的92.91%降至79.75%,氟中毒症状与体征阳性检出率由24.00%降至16.57%,儿童尿氟含量测定由几何均值7.8mg/1 降至3.80mg/1。三项指标前后对比经统计学处理均有非常显著性差异和极显著性差异。从而说明,活性氧化铝药物降氟的效果是可靠的。
Wang Hanzhuang Yangyuan County, the use of activated alumina drugs fluoride to water, three years after the children aged 8-12 dental fluorosis detection rate decreased significantly from 92.91% three years ago dropped to 79.75%, fluorosis and signs The positive detection rate decreased from 24.00% to 16.57%. The urinary fluoride content in children decreased from the geometric mean of 7.8mg / 1 to 3.80mg / 1. Before and after the comparison of the three indicators have statistically significant differences and very significant differences. This shows that the activated alumina drug fluoride effect is reliable.
