Abstract
Fluoride release studies from model glass polyalkenoate cements show the release to be proportional to the fluorine content of the glass. The dominant fluoride release mechanism is by an ion exchange mechanism, where fluoride ions are exchanged for hydroxyl ions in water, rather than via a counter ion mechanism involving simultaneous release of an alkali metal ion. The ion exchange mechanism explains the recent reduction in pH observed in cell culture studied. Negligible amounts of aluminium are released and virtually no fluorine is released bound to aluminium from the set cement.
