چکیده انگلیسی مقاله Background & Aim: Fluoride released from restorative materials was known as an effective factor to prevent secondary caries. The purpose of this study was to compare the fluoride ion release from two conventional glass­ionomers; Ionocid–F and Fuji II and two Resin- modified glass-ionomers; Iono Gem LC and Fuji II LC. Methods & Materials: In this experimental study, five disc – shaped specimens (7×2mm) from each material were prepared. The specimens were placed in plastic containers with 10cc of deionized water. The solutions were changed daily up to one week and thereafter every 12 days for three consecutive days. This regimen was repeated four times over a period of 2 months. Solutions were buffered with TISAB II and fluoride measurements were carried out using a fluoride ion-selective electrode connected to a pH ion-selective electrode meter. The results were converted to ppm. Statistical analysis were conducted using ANOVA and Scheffe. Result: All of the materials showed high initial release values which decreased significantly in second day. Ionocid–F (267.643±17.916 ppm) released significantly more fluoride ions during two months which followed by Iono Gem LC (101.284±10.068 ppm), Fuji II LC (23.276±2.609 ppm) and Fuji II (20.027±4.232 ppm).   However, there was no significant difference between Fuji II LC and Fuji II.   Conclusion: There was a wide variation of fluoride ion release from the materials but patterns of release were similar
