    • A two-part oral product capable of remineralizing subsurface lesions and/or mineralizing exposed dentinal tubules in teeth is composed of cationic and anionic discrete parts. The cationic discrete part contains at least one water-soluble calcium salt and, preferably, at least one non-toxic, water-soluble salt of a divalent metal other than calcium, and a first pharmaceutically acceptable carrier. The anionic discrete part contains at least one water-soluble phosphate salt and, preferably, at least one water-soluble fluoride salt, and a second pharmaceutically carrier. Preferably, one of the carriers is an aqueous carrier and the other of the carriers is a non-aqueous carrier. The cationic and anionic parts are simultaneously released from the product upon mixing of the product with water and/or saliva to form the mixed aqueous solution. In this way, calcium ions released by the calcium salt and phosphate ions released by the phosphate salt are simultaneously delivered to the tooth surfaces by the solution. To effect subsurface remineralization and/or mineralization, the parts are mixed together to form the mixed aqueous solution, and the solution is then promptly applied to the teeth for a period of time sufficient to allow calcium ions and phosphate ions to diffuse through the tooth surface to the subsurface, where the ions react to form an insoluble precipitate onto the lesion and/or tubule, thereby remineralizing such lesion and/or mineralizing such tubule.
    • 能够再次矿化地下病变和/或使牙齿中暴露的牙质小管矿化的两部分口服产品由阳离子和阴离子分立部分组成。 阳离子分散部分含有至少一种水溶性钙盐,优选至少一种无钙水溶性的钙以外的二价金属的盐和第一药学上可接受的载体。 阴离子离子部分含有至少一种水溶性磷酸盐,优选至少一种水溶性氟化物盐和第二种药物载体。 优选地,载体之一是水性载体,另一种载体是非水载体。 当产品与水和/或唾液混合时,阳离子和阴离子部分同时从产物中释放出来以形成混合的水溶液。 以这种方式,由磷酸盐释放的钙盐和磷酸根离子释放的钙离子被溶液同时输送到牙齿表面。 为了实现地下再矿化和/或矿化,将这些部分混合在一起以形成混合的水溶液,然后将溶液迅速施加到牙齿上一段足以允许钙离子和磷酸根离子通过牙齿表面扩散的时间 到地下,其中离子反应以在病变和/或小管上形成不溶性沉淀物,从而使这种损伤和/或矿化这种小管再矿化。
