Background: The antibacterial effect and cariostatic properties of glass –ionomer cement are associated with the amount of fluoride released ,therefore the aim of the study was to evaluate fluoride release from three different glass ionomer cement (GIC)-based restorative materials .
Materials and methods :a total of 42 samples of extracted caries free permenant molars were obtained as 14 samples from each group .group A(FujiIX:resin modified glass ionomer cement),group B (Voco:TGIC) and group C (Ketac Molar) each tooth was prepared for conventional class I cavity preparation , followed by application of the restorative material then kept in artificial saliva to be examined for fluoride release after 48hours,7,15,28 days using Orion fluoride electrode .
Results: according to the measures repeated analysis ,there is different in fluoride release between the study groups according to the time interval ,where group A showed the statistically significant value in relation to group B&C(P<0.005).
Conclusions :this study showed that FujiIX was determined to be the material of the highest fluoride release value.
