Fluoride release from a fluoride-containing amalgam, a glass ionomer cement and a silicate cement in artificial saliva.

This study aimed to compare the fluoride release from a fluoride-containing amalgam, a silicate cement and a glass ionomer cement in artificial saliva. After storing specimens in an artificial saliva for 7 weeks, the fluoride content in the solvent was measured by a spectrophotometric method. The fluoride release from silicate cement was about 5 times greater than from glass ionomer cement, which again showed a release 4 times greater than the fluoride-containing amalgam. The fluoride release relative to fluoride content in test specimens was greater from fluoride-containing amalgam and silicate cement than from glass ionomer cement.
