Abstract: Background and Aim: Fluoride release in oral cavity is effective in prevention of caries in the walls of cavities and remineralization of initianal lesions . There is considerable variation in the amount of fluoride release from restorative materials. The aim of this study was to determine the amounts of fluoride release from three self-cured glassionomers, GC, SDI, SDS in distilled water and artificial saliva. Materials and Methods Through an in Vitro study 6 specimens of each three glassionomers were prepared . One specimens of each materials was placed in distilled water and the other three disc inserted into non-fluoridated artificial saliva . Fluoride release was determined at 1,7 ,14,28,56,70,84 days by using a fluoride ion-specific electrode. Data was analyzed using repeated measurement ANOVA and LSD test. Results : Pattern of fluoride release from three glassionomers were similar. The highest amounts of fluoride was released from SDS into water and artificial saliva(p<0/001) . GC and SDI released similar amount of fluoride in water . Conclusion : Apart from the type of glassionomers , fluoride release into the water was higher than artificial saliva . The highest amount of fluoride was released from SDS into both water and artificial saliva(p<0/001) . |
