The preponderance of evidence indicates that sodium monofluorophosphate exerts a highly beneficial effect on dental caries incidence and enamel solubility. Optimal effects are obtained with a concentration of 4 X 10(3) ppm fluoride, by a four-minute application and by adjusting the pH to 4.0. The reaction of sodium monofluorophosphate with enamel is not temperature dependent. Sodium monofluorophosphate is significantly more protective than sodium fluoride in aqueous solutions at all equivalent fluoride concentrations and in pastes at concentrations exceeding 8 X 10(3) ppm fluoride.
大量证据表明，单氟磷酸钠对龋齿发病率和牙釉质溶解性具有高度有益的影响。当氟化物浓度为4×10³ ppm、作用4分钟并将pH值调节至4.0时，可获得最佳效果。单氟磷酸钠与牙釉质的反应不依赖于温度。在所有等效氟化物浓度的水溶液中以及在氟化物浓度超过8×10³ ppm的糊剂中，单氟磷酸钠的防护作用明显优于氟化钠。
