Tooth erosion is becoming increasingly prevalent. Tooth erosion is the irreversible loss of tooth tissue caused by chemical dissolution by acids without the intervention of plaque bacteria involved in tooth decay, therefore contemporary restorative techniques are unwanted. Strontium that enhances the activity of Osteoblast is applied to the treatment of osteoporosis in medicine field. In dental field. However, there is few reports on the effects of Sr on enamel remineralization. It was comfirmed that the concentration of Sr-F combination the most effectively involved in the acquisition of high quality remineralization enamel was Sr aqueous solution+ 0. 05ppm F and the most effectively concentration of Sr-F combination enhances F penetration with the combination of large ionic radius Sr acquired the high quality enamel remineralization.

牙齿腐蚀变得越来越普遍。牙齿腐蚀是由酸的化学溶解引起的牙齿组织的不可逆转的损失，没有牙菌斑细菌的干预，因此当代修复技术是不需要的。锶具有增强成骨细胞活性的作用，在医学上应用于骨质疏松症的治疗。在牙科领域。然而，关于锶对牙釉质再矿化作用的报道很少。结果表明：Sr水溶液+ 0是Sr- f组合对高质量再矿化牙釉质获得最有效的浓度。05ppm F与最有效浓度Sr-F的结合增强了F的穿透力，与大离子半径Sr的结合获得了高品质的牙釉质再矿化。
