We have developed a new fluorine quantitative measurement method using a micro-PIXE (Proton Induced X-ray Emission) / PIGE (Proton Induced Gamma-ray Emission). By using this measurement method, it has become possible for the first time to catch the movement of fluorine upon demineralization of tooth. Further, it was shown that the fluorine in the tooth released with decalcified was again taken into the tooth.The possibility that concentration value of fluorine in the tooth measured conventionally was contained both those not attached to the tooth, such as CaF2, and those attached to the tooth, has been shown.

我们开发了一种使用微型 PIXE（质子诱导 X 射线发射）/PIGE（质子诱导伽马射线发射）的新氟定量测量方法。通过使用这种测量方法，首次可以捕获牙齿脱矿质时氟的移动。此外，表明脱钙后释放的牙齿中的氟再次被摄入牙齿中。传统测量的牙齿中氟的浓度值可能包含未附着在牙齿上的氟(例如CaF2)和附着在牙齿上的氟。到牙齿，已被证明。
