A comparison of fluoride release from four glass-ionomer cements.
Fluoride release from three glass-ionomer cements and one cement was measured over 1 year and compared. All the materials released fluoride in a similar pattern for the study's duration: The fluoride release was greatest on the first day, decreased sharply the second day, and gradually diminished. After 1 year, all specimens released daily fluoride concentrations above 0.5 ppm, reaching as much as 7 ppm. Low powder-liquid ratios always lead to more fluoride release than high ratios.
