This paper reviewed the relationship between fluoridated milk and dental caries prevention derived from the preceding academic research. Several topics, including milk fluoridation, fluoridated milk in animal and human clinical studies, the effect of fluoridated milk to fluoride concentration in saliva and dental plaque, the bioavailability of fluoridated milk, and the effect on human teeth were discussed.

本文回顾有关牛奶与龋齿间关系以及牛奶氟化以预防龋齿的文献，从牛奶氟化的最初想法，到氟化牛奶的动物实验、人类临床实验，进一步研究对唾液、牙菌斑中含氟量的影响，以及氟化牛奶的生物可得性，最后探讨对人类牙齿的抗酸溶解力的改变。

On the other hand, 3(2)-fluoro-4-methoxyl methyl benzyl alcohol and 3(2)-fluoro-4-methyl benzyl alcohol are mixture and components of pyrethrum esters. Both of them have "mixture fluorine effect " and higher activity, lower drug resistance. As we know, the mixture benzyl alcohol containing fluorine is more easy to be synthesized than the single, so the cost of preparation is lower. We hope to apply it to molecule design of the new agriculture chemical. On the base of molecule design and structure-activity relationship research of pyrethric acid II and mixture of alcohol containing fluorine, we intend to get new pyrethrum ester that have higher activity and lower resistance.

另一方面，混合含氟对甲氧甲基苄醇和混合含氟对甲苄醇都是具有"混合氟效应"的高活性、低抗性的拟除虫菊酯醇组分，由于混合含氟醇的合成要比单一异构体的合成容易，成本较低，本文希望将其应用到新农药的分子设计中，用第二菊酸和一些含氟醇进行分子设计及进一步的构效关系的研究，筛选出一些高活性低抗性的拟除虫菊酯换代新品种。
