  • Title: Demineralization inhibition at glass-ionomer cement and amalgam restoration margins in conjunction with additional fluoride regimens.
    Author: Donly KJ, Kerber L.
    Journal: Spec Care Dentist; 1999; 19(1):24-8. PubMed ID: 10483457.
    Abstract:
    The purpose of this study was to evaluate demineralization inhibition at restoration gingival margins. The study compared the effectiveness of a fluoride-releasing restorative material and topical fluoride regimens utilized individually and in conjunction with fluoridated materials. Glass-ionomer restorations demonstrated significantly less dentin demineralization than amalgam restorations at restoration margins when the restorations were exposed to no external fluoride, when the restorations were brushed with a fluoridated dentifrice twice per day, and when the restorations were exposed to a fluoride rinse (p, 0.05). There was no significant difference in dentin demineralization adjacent to glass-ionomer and amalgam restorations when both a fluoride rinse and a fluoridated dentifrice were used on a daily basis over 30 days, in vitro.
