Statement of problem: Secondary caries are the prime concern after the restoration and tooth receiving crown. As time progresses the chances of secondary caries increases if suitable restorative material is not used. Aim of the study : This study evaluate the fluoride releasing ability of three different types of Glass Ionomer formulation including Glass Ionomer cement(GC-9, Gold lable), Glass Ionomer FX-II (shofu-Japan), Ketac Molar(3M). Methodology : A total of 10 cylindrical specimen for each of 3 materials were prepared followed by manufacturer instructions & immersed independently in 25 ml of artificial saliva & stored as group-1 to 3. The Fluoride release was evaluated on 1st , 7th & 28th day using fluoride ion specific electrode. Summary of Result : Our study showed that all 3 types of glass-ionomer cements released fluoride. The most important fluoride release took place during the first 24 hours. It then gradually increased and became constant during the following days of the study. Our results in the first 24hrs demonstrated that the concentrations of fluorine ions released were insignificantly higher in all three groups. But release of fluoride is comparatively lower in FX-II than GC-9 and Ketac molar.There is considerable increase in fluoride release was seen in all three groups in at 7th day. Though FX-II has maintained lower release compared to GC-9 and Ketac molar. Over all release of fluoride is diminished at the 28th day
