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.
为确定围绕美国公共卫生服务局推荐的0.7毫克/升饮用水氟化物浓度的控制范围，以预防龋齿，对疾病控制与预防中心2006 - 2010年及2015年的水氟化报告系统数据进行了分析。将2006 - 2010年255,060个系统月中的191,266个系统月的4,251个经氟化物调整的社区供水系统的月平均浓度数据，与宽度为0.6毫克/升至0.2毫克/升的控制范围进行比较。控制范围宽度≥0.4毫克/升（例如±0.2毫克/升）时，系统月数的百分比>83%，而宽度为0.2毫克/升（±0.1毫克/升）时为68%。2015年，70%的调整后系统在12个月中的9个月内，其平均值保持在系统年平均值的±0.1毫克/升范围内，67%采用了0.7毫克/升的目标值，45%采用了±0.1毫克/升的控制范围。2015年正在采用0.7毫克/升的目标值，但尚未完成。对于月平均氟化物浓度而言，窄于±0.2毫克/升的控制范围可能是可行的。
