摘要：

The present invention refers to oral care and oral hygiene products having photocatalytic activity comprising particles of a calcium phosphate compound, superficially functionalised with TiO2 nanoparticles in crystalline form, said TiO2 nanoparticles having: a) a substantially lamellar morphology； b) an aspect ratio (AR) comprised between 5 and 30； c) a surface structure having face (001) as outermost face of the crystalline lattice； and d) wherein the TiO2 is in the form of anatase, optionally mixed with rutile and/or brookite.
