TERADA, Raquel Sano Suga et al. IN VITRO FLUORIDE RELEASE FROM GLASS-IONOMERCEMENTS AND OTHER MATERIALS. Rev Odontol Univ São Paulo [online]. 1998, vol.12, n.1 ISSN 0103-0663. http://dx.doi.org/10.1590/S0103-06631998000100013.
The aim of this study was to determine the fluoride release from six fluoride-containing materials over 28 days. The results showed that the fluoride release patterns were similar for all glass ionomers tested, i.e., a large initial release was followed by a rapid decline in the amount released within the second day but became relatively stable after seven days. The release from glass ionomer cements was clearly greater than that from a sealant and a composite resin. Vidrion R released the largest amount of fluoride among all tested materials.
