    摘要： It is intended to provide a remineralization promoter for tooth enamel and a composition for an oral cavity, which can highly effectively promote the remineralization of tooth enamel and strongly inhibit dental caries. The remineralization promoter for tooth enamel and the composition for an oral cavity are characterized by containing amorphous hydroxyapatite and/or amorphized hydroxyapatite showing two peaks at 2θ=31 to 35° in X-ray diffraction. The amorphized hydroxyapatite is obtained by reacting calcium salt with phosphate in an aqueous solution and drying the reaction solution at a temperature of 10 to 70° C.

    摘要： A toothbrush includes a bristle portion having implanted bristles and molded from an ion eluting-type ceramic, a conductor extending into the interior of the bristle portion, and a battery to which the conductor is connected. An electric current flows from the user's hand toward the surface of the teeth through the user's body as the teeth are brushed, thereby causing calcium of fluorine ion, which elutes from the ceramic constituting the bristle portion, to be deposited onto and to penetrate the teeth and dental pulpa while tartar is removed from the surface of the teeth by electronic decomposition.

    摘要： Anti-bacterial composite particles which comprise a polymer base material comprising a thermal melting polymer, such as a polyolefine, exhibiting good dispersibility in a basic material resin and having a lower molecular weight or a lower softening point than that of the basic material resin, and inorganic fine particles comprising a metal having anti-bacterial activity carried thereon. An antibacterial resin composition can be prepared by melting and kneading a synthetic resin composition as the basic material resin together with the anti-bacterial composite particles and forming by known molding methods such as extrusion molding and injection molding, and can be used for producing various synthetic resin moldings which have an inorganic anti-bacterial agent uniformly dispersed in a synthetic resin composition and thus exhibits good anti-bacterial effect.
