Our electron microprobe studies show the preferential incorporation in vitro of tin and fluorure into carious dentin. These ions do penetrate only into carious dentin through the body of the lesion. These ions do not progress through the sclerotic dentin barrier, when it exists which tend to demonstrate their affinity for demineralized tissues. Results of microprobe analysis may suggest the hypothesis of a crystalline arrangement as the product of reaction between residual apatite in carious dentin with stannous fluoride. A new crystalline phase could occur within the carious zone, up to the sclerotic barrier. This method does not permit to indicate its identity or its structure. However, it has been recognized in previous studies as a tin phosphate compound. Further analytic studies, using crystallographic technics of the treated zones could provide additional data of the observations from the electron microprobe and confirm the hypothesis of the ability of carious dentin to be remineralized by the use of stannous fluoride containing solutions or materials.
我们的电子微探针研究表明，在体外，锡和氟优先掺入龋坏牙本质中。这些离子仅通过病变体部渗入龋坏牙本质。当存在硬化牙本质屏障时，这些离子不会穿过该屏障，这往往表明它们对脱矿组织具有亲和力。微探针分析结果可能提示一种晶体排列假说，即龋坏牙本质中的残余磷灰石与氟化亚锡反应的产物。在龋坏区内直至硬化屏障可能会出现一种新的晶相。这种方法无法确定其身份或结构。然而，在先前的研究中它被认为是一种磷酸锡化合物。使用处理区域的晶体学技术进行进一步的分析研究，可以提供来自电子微探针观察的更多数据，并证实龋坏牙本质能够通过使用含氟化亚锡的溶液或材料进行再矿化的假说。
