    Fluorine-carrying vinylphosphonate copolymers release fluoride to calcium hydroxyapatite and tooth enamel. These findings suggest potential applications for these copolymers as effective caries preventive agents.

    Area of Science:

    • Materials Science
    • Biomaterials
    • Polymer Chemistry

    Background:

    • Dental caries remains a significant public health concern.
    • Fluoride ions are well-established agents for caries prevention.
    • Novel delivery systems for fluoride are needed to enhance efficacy.

    Purpose of the Study:

    • To investigate fluoride release from novel fluorine-carrying vinylphosphonate copolymers.
    • To evaluate the interaction of these copolymers with calcium hydroxyapatite and tooth enamel.
    • To assess the potential of these copolymers as caries preventive agents.

    Main Methods:

    • Potentiometric determination of fluoride ions released to calcium hydroxyapatite.
    • Auger spectroscopy analysis of fluoride release to tooth enamel.

    Related Experiment Videos

  • Synthesis and characterization of vinylphosphonate copolymers.

    • Main Results:

    • The vinylphosphonic acid and vinylphosphonyl thiofluoride copolymer demonstrated fluoride release to both calcium hydroxyapatite and tooth enamel.
    • The oxygen analog copolymer showed similar fluoride release to calcium hydroxyapatite but not to tooth enamel.
    • Adsorbed copolymers effectively released fluoride ions.

    Conclusions:

    • Fluorine-carrying vinylphosphonate copolymers can release fluoride ions upon interaction with dental substrates.
    • These copolymers show promise as novel caries preventive agents.
    • The combination of polyphosphonate effects and fluoride release offers a dual mechanism for caries prevention.
