Unverified含氟量常见换算：1450ppm≈0.32%单氟磷酸钠或0.24%氟化钠；1000ppm≈0.22%氟化钠。看配料表氟化物百分比即可反推浓度85% similarUnverified含氟浓度为0.02%氟化钠（约220ppm氟离子），属于儿童漱口水的常规低浓度水平，提供基础防龋保护但不能替代含氟牙膏的刷牙步骤83% similarUnverified标准防蛀含氟漱口水的常见浓度为0.05%氟化钠（约226ppm氟），用于每日使用；0.2%氟化钠（约900ppm）为每周一次的高浓度方案，一般不用于低龄儿童日常79% similarUnverified中国标准GB允许含氟漱口水氟浓度不超过0.05%（约226ppm），儿童防龋用漱口水氟含量通常标注为100-225ppm；成分表应能查到氟化钠（Sodium Fluoride）具体浓度而非仅写'含氟'77% similarUnverified含氟量单位换算：0.05% NaF ≈ 226ppm氟，0.11% ≈ 500ppm，0.24% ≈ 1085ppm，看到百分比标注可据此推算是否适龄76% similar
