<p>Together with other accessory products, includes a mixture of ion-exchange resins, cationic and anionic, charged with Ca<2+>, F<-> and PO4<3-> ions, in an approximate molar ratio of 2:1:1, respectively. Particularly preferred is a material in which the resins also have a charge of Zn<2+> ions representing a proportion of less than 1%, preferably close to 0.2% of the dry weight of the resin. The preferred resins are those whose base is cross-linked polystyrene with 2-14% divinylbenzene. The material is useful as first filler in the treatment of caries, especially deep caries, leading to remineralization of the dentin with a composition very close to the original composition, together with high microhardness. It is also useful as a component of dentifrice products such as pastes, elixirs and dental floss.</p> |
