Demineralization inhibition at glass-ionomer cement and amalgam restoration margins in conjunction with additional fluoride regimens.
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.
