摘  要：本研究的目的是在饮用水不同氟浓度条件下，调查龋齿和氟斑牙的关系。评价其他氟化物产品的影响。饮用氟浓度分别为<0.3、0.3-<0.7、0.7-1.2和>1.2ppm的水时，儿童氟中毒出现率为13.5%、21.7%、29.9%和41.4%。本研究使用1986-1987年美国全国在校学生调查数据。采用学校饮水氟化物的水平作为在校学生水氟暴露的一个指标。使用问卷调查确定氟滴、药片、专业氟化物治疗和学校氟漱的使用。仅仅对长期连续居住的儿童（n=18755）进行分析。结果：水中氟浓度在0-0.7ppm范围内时，龋齿指数和龋失补牙面指数随氟浓度的增加而减少，然而在氟浓度为0.7-1.2ppm时，其减少幅度很小。除了饮用水的氟化，使用加氟措施与龋齿和氟中毒也紧密相连。结论：在氟浓度为0.7ppm时，龋齿和氟中毒呈现出一个良好的平衡。本研究数据表明，需要复议适合于美国最佳水氟化浓度的政策。

Abstract: Objectives: The purpose of this study was to investigate the relationships

between caries experience and dental fluorosis at different fluoride concentrations in drinking water. The impact of other fluoride products also was assessed. Methods: This study used data from the 1986-87 National Survey of US School children. Fluoride levels of school water were used as an indicator of the children’s water fluoride exposure. The use of fluoride drops, tablets, professional fluoride treatments, and school fluoride rinses were ascertained from caregiver questionnaires. Only children with a single continuous residence (n=18,755) were included in this analysis. Results: the sharpest declines in dfs and DMFS were associated with increases in water fluoride levels between 0 and 0.7 ppm F, with little additional decline between 0.7 and 1.2 ppm F. Fluorosis prevalence was 13.5 percent, 21.7 percent, 29.9 percent, and 41.4 percent for children who consumed <0.3, 0.3 to <0.7, 0.7 to 1.2 and >1.2 ppm F water. In addition to fluoridated water, the use of fluoride supplements was associated with both lower caries and increased fluorosis. Conclusions: A suitable trade-off between caries and fluorosis appears to occur around 0.7 ppm F. Data from this study suggest that a reconsideration of the policies concerning the most appropriate concentrations for water fluoridation might be appropriate for the United States.
