Dental materials are considerably different regarding the amount of fluoride release. This study aimed to determine the amount of fluoride release from three self-cure glass ionomer cements, Fuji I, Fuji Plus and SDS in distilled water.   Materials and Methods: In this experimental study, 8 disc-shape specimens (3×10mm) were prepared from three glass ionomers, Fuji I and Fuji Plus (CG, Japan) and SDS (Iran). Eight specimens of each material were placed in 7ml of distilled water and were stores in incubator at 37oC. The amount of fluoride release was measure at 1, 3, 7, 14, 28 and 56 days using a fluoride ion-specific electrode (Metrohm, Switzerland). Data were analyzed using repeated measurement ANOVA and LSD tests.       Results: The pattern of fluoride release was similar for the three materials. The amount of released fluoride from the three material in day 1 was considerably greater than the other days (Fuji I=28.07±0.26, Fuji Plus=35.97±0.19, SDS=41.08±0.36), followed by a gradual decrease over the study period. The least amount of fluoride release was recorded on day 56. The difference between the amount of fluoride release from the three glass ionomers was statistically significant (P=0.0001).       Conclusions: In addition to revealing a statistically significant difference between the three glass ionomers in terms of fluoride release, the results of this study suggests using SDS glass ionomer in patients susceptible to caries.       سمان گلاس آینومر, گلاس آینومر نسوجی, ماده پر کردنی, گلاس آینومر Glass ionomer cement, Fuji Glass ionomer, Filling material, Glass ionomer 190 195 http://jrds.ir/browse.php?a_code=A-10-822-1&slc_lang=fa&sid=1 MH Salari محمد حسن سالاری 10031947532846009581 10031947532846009581 No SH Lawaf شیرین لواف Drshlawaf@yahoo.com 10031947532846009582 10031947532846009582 Yes A Azizi آرش عزیزی 10031947532846009583 10031947532846009583 No A Kazemi salehi آزاده کاظمی صالحی 10031947532846009584 10031947532846009584 No
