title: [A study of fluoride-containing composite resins: fluoride release, water sorption and dissolution].
abstract: 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.
