Fluoride uptake from a composite restorative by enamel.

    Dental Materials : Official Publication of the Academy of Dental Materials
    |January 1, 1989
    PubMed
    Summary

    This study shows that enamel near a fluoride-releasing dental composite can absorb significant fluoride. This fluoride uptake suggests the composite may help prevent cavities in clinical use.

    Area of Science:

    • Dental Materials Science
    • Cariology
    • Biomaterials

    Background:

    • Dental composites are widely used restorative materials.
    • Fluoride-releasing materials offer potential anticariogenic benefits.
    • Understanding fluoride release and uptake is crucial for material efficacy.

    Purpose of the Study:

    • To investigate the in vitro fluoride uptake by human enamel adjacent to a novel fluoride-releasing composite restorative material.
    • To quantify the amount and depth of fluoride penetration into enamel.
    • To assess the potential anticariogenic properties of the composite based on fluoride release.

    Main Methods:

    • Human enamel blocks were exposed to a fluoride-releasing composite disc in synthetic saliva for up to 24 hours.
    • Fluoride content in successive enamel layers was analyzed using specific ion-electrode analysis.
    • Atomic absorption analysis determined calcium content for precise layer thickness measurement.

    Main Results:

    • Significant fluoride uptake was observed in enamel adjacent to the composite material.
    • The outermost 10-micron enamel layer reached a fluoride concentration of 5400 ppm after 24 hours.
    • Demonstrated in vitro fluoride diffusion from the composite into surrounding enamel.

    Conclusions:

    • The fluoride-releasing composite effectively transfers fluoride to adjacent enamel in vitro.
    • The substantial fluoride uptake indicates promising anticariogenic potential for clinical application.
    • Further in vivo studies are warranted to confirm the cavity-preventing efficacy of this restorative material.
