Long-term F release from glass ionomer cements
M. L. Swartz, R. W. Phillips and H. E. Clark
Fluoride release from three commercial glass ionomer filling cements and
three glass ionomer luting cements was measured in the laboratory over a
12-month period. Fluoride release from these glass ionomer cements was
compared with that released from a silicate, silicophosphate, and a
fluoride-containing polycarboxylate cement. The fluoride released from the
glass ionomer cements throughout the one-year period was similar, both in
quantity and pattern, to that released by the silicate cement. The
silicophosphate cement tended to release fluoride in somewhat lesser
amounts, while the amount of fluoride released by the polycarboxylate was
negligible after the first few days. Analysis of these data indicates that
these glass ionomer cements probably possess anticariogenic properties
similar to those of silicate cement.
