To inform selection of a control range around the Public Health Service's recommended 0.7 mg/L drinking water fluoride concentration to prevent tooth decay, CDC's Water Fluoridation Reporting System data for 2006-2010 and 2015 were analyzed. Monthly average concentration data from 4,251 fluoride-adjusted community water systems for 191,266 of 255,060 system-months (2006-2010) were compared to control ranges 0.6 mg/L to 0.2 mg/L wide. Percentages of system-months within control ranges ≥0.4 mg/L wide (e.g., ±0.2 mg/L) were >83% versus 68% for 0.2 mg/L wide (±0.1 mg/L). In 2015, 70% of adjusted systems maintained averages within ±0.1 mg/L of their system's annual average for 9 of 12 months, 67% used the 0.7 mg/L target and 45% used it with a ±0.1 mg/L control range. Adoption of the 0.7 mg/L target was underway but not completed in 2015. Control ranges narrower than ±0.2 mg/L may be feasible for monthly average fluoride concentration.

调整了 34 个州的氟化物浓度和控制范围 - 2006 年至 2010 年和 2015 年。

为了帮助选择公共卫生服务推荐的 0.7 mg/L 饮用水氟化物浓度以防止蛀牙的控制范围,我们对 CDC 水氟化报告系统 2006-2010 年和 2015 年的数据进行了分析。将 255,060 个系统月(2006 年至 2010 年)中 191,266 个 4,251 个氟调节社区水系统的月平均浓度数据与 0.6 mg/L 至 0.2 mg/L 范围内的对照范围进行了比较。控制范围≥0.4 mg/L 范围(例如±0.2 mg/L)的系统月百分比>83%,而0.2 mg/L 范围(±0.1 mg/L)控制范围内的系统月百分比为68%。2015 年,70% 的调整后系统在 12 个月中有 9 个月将平均值保持在系统年平均值的 ±0.1 mg/L 范围内,67% 使用 0.7 mg/L 目标,45% 使用 ±0.1 mg/L 控制范围。0.7 mg/L 目标的采用正在进行中,但在 2015 年尚未完成。对于月平均氟化物浓度,控制范围窄于 ±0.2 mg/L 可能是可行的。
