Fluoride release from a fluoride-containing amalgam and two luting cements.
The release of fluoride from an amalgam and two luting cements, silicophosphate and polycarboxylate, was studied by shaking test specimens in a solution with hydroxyapatite, and measuring the fluoride taken up by the apatite. The initial release was significant for all three materials. After 1 week the amalgam released only minor amounts of fluoride, whereas the cements continued to liberate fluoride during the 5-week observation time to the same extent as silicates in earlier studies.
