Quantitative elucidation of change in fluorine associated with caries progression and inhibition

我们开发了一种新的氟定量测量方法，使用微型PIXE（质子诱导X射线发射）/ PIGE（质子诱导γ射线发射）。通过使用这种测量方法，它已成为可能的第一次捕捉氟的运动时，牙齿脱矿。此外，还证明了脱钙后释放的牙齿中的氟再次被吸收到牙齿中，并证明了常规测量的牙齿中的氟浓度值包含CaF 2等未附着在牙齿上的氟和附着在牙齿上的氟的可能性。

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.
