Current study is aimed to compare fluride release in conventional glass ionomer, light-cured glass ionomer and compomers. Standard samples from the aforementioned materials were prepared and measured by selective fluride ion electrode in intervals of 24hours, 1,2,3 and 4 weeks in neutral PH of 7 and acidic PH of 4.5. The obtained data represented that fluride ion release decreased in time but the pattern of this issue was different. Besides, it was found that in lower Ph fluride release is significantly affected. Compomer relatively releases less fluride than the others but as long as this amount can sufficiently prevent caries development, it can be stated that based on clinical status any of above choices can be selected. Besides, the more easily handled and available materials are used, the more successful the clinical results will be achieved.
