[A study of fluoride-containing composite resins: fluoride release, water sorption and dissolution].
OBJECTIVE
To study fluoride release and its impact on the basic properties.


METHODS
Fluoride releasing was determined by F-electrodes, water sorption and dissolution of the materials were determined by weight/volume loss technique.


RESULTS
The profile of fluoride release from fluoride-containing composites was different from that of compomer. Meanwhile, fluoride-containing materials showed larger values of water sorption (13.05-31.64 micrograms/mm3) and dissolution(5.88-24.80 micrograms/mm3) than controls.


CONCLUSIONS
The F- releasing may affect physical and mechanical properties of fluoride-containing composites.
