This invention involves new compositions and methods of use and delivery of amorphous calcium compounds such as: amorphous calcium phosphate (ACP), amorphous calcium phosphate fluoride (ACPF), amorphous calcium carbonate phosphate (ACCP), amorphous calcium carbonate phosphate fluoride (ACCPF), and amorphous calcium fluoride (ACF) for use in remineralizing and fluoridating teeth. These amorphous compounds or solutions which form the amorphous compounds or calcium phosphate jelly which forms the amorphous compounds, when applied either onto or into dental tissue to prevent and/or repair dental weaknesses such as dental caries, exposed roots and dentin sensitivity. The compounds have the highest solubilities, fastest formation rates and fastest conversion rates (to apatite) among all the calcium phosphates under physiological conditions. Moreover, in the presence to fluoride the amorphous compound convert rapidly to fluoride containing apatite.
本发明涉及新的组合物和使用方法以及输送无定形钙化合物,例如:无定形磷酸钙(ACP),无定形磷酸钙氟化物(ACPF),无定形碳酸钙磷酸盐(ACCP),无定形碳酸钙磷酸氟化物(ACCPF)和无定形氟化钙(ACF)用于牙齿的再矿化和氟化。这些无定形化合物或形成无定形化合物的溶液或形成无定形化合物的磷酸钙凝胶,当施加于或进入牙齿组织以预防和/或修复牙齿的弱点,例如龋齿,暴露的根和牙本质敏感。这些化合物在生理条件下具有最高的溶解度、最快的形成速率和最快的转化速率(到磷灰石)。此外,在氟化物存在的情况下,无定形化合物会迅速转化为含氟磷灰石。
