| 摘要 |
A system for the strategic controlled delivery of materials to the dental surfaces of the intraoral cavity, in particular materials having a desired or predetermined activity with respect to such dental surfaces for example by forming a specific controlled microenvironment. In particular, the system enables delivery of fluoridizing and other agents to interproximal (approximal) sites among others, to enable inter alia the prevention, treatment, diagnosis, elimination or retardation of dental disease and sensitivity and to provide cosmetic changes. A novelty of this invention is the development of a single or multiphase delivery system in single, bi or multi layer or bi or multi location form or continuation thereof for the optimal delivery of a material or materials to at least one specific dental site with or without other optimal and/or physical intervention.
