The paper described the results of experiment performed on animals concerning the effect of fluoride tooth-pastes on a calcium-phosphate and sodium-phophate basis in the field of caries prevention. The caries infection is ascertained for varying test durations on the basis of serial grindings. It turns out that the anti-carieseffect of fluoride is greatly diminished if soluble calcium salts are present in the paste.
该论文描述了在动物身上进行的实验结果，这些实验涉及以磷酸钙和磷酸钠为基础的含氟牙膏在预防龋齿方面的效果。通过连续研磨，在不同的测试时间段确定龋齿感染情况。结果表明，如果牙膏中存在可溶性钙盐，氟的防龋效果会大大降低。
