Formulation and method for treatment of teeth

摘要

Tooth dentin is treated by applying thereto a paste or other solution to effect plugging of the tubules to eliminate or reduce tooth sensitivity. The solution may be applied to other tooth components for treatment thereof. The solution has a lanthanide salt dissolved therein and a pH between about 6 and 7 and includes an agent for bulking so as to enhance the plugging effect. A dental restoration has incorporated therein lanthanide ions.

1. A formulation for application to and retention on teeth to plug tubules thereof and/or for re-mineralization thereof, the formulation consisting essentially of a solvent, a lanthanide salt dissolved in said solvent, and a lanthanide oxide and a binder which binds said lanthanide oxide into the formulation, wherein pH of the formulation is between 6 and 7 and is maintained between 6 and 7 when applied to and retained on teeth to plug tubules thereof and/or for re-mineralization thereof, and wherein said lanthanide oxide is selected from the group consisting of gadolinium oxide, cerium oxide, lanthanum oxide, and samarium oxide.
