The present of fluoride in filling materials stabilize the pH value i.e. these materials decrease cariogenesis. The equations concerning fluoride kinetic release from glass ionomer cements, compomers and compositions were made. It was stated that the fluoride release mechanism is complicated and yet has not been explained. It was noted that the released amount of fluoride depends on the environment pH and same filling materials have an ability of catching the fluoride ions from solution if their concentration in the environment is higher than in the material. The purpose of the work\: The purpose of this work is the quantitative determination of fluoride ion release to the artificial saliva from glassionomer cement Fuji II LC Improved and compomer Dyract Extra. Methodology\: Fillings were applied to thirty cavities i.e. fifteen for each filling in prepared acrylic teeth. Cavities of equal size were made using electronic double – sided millimeter slide rule with measurement accuracy 0,01 mm made by firma Kinex. Tooth were weighted before and after filling to obtain the mass of filling material. The artificial saliva solution was made according to Fusayama prescription modified by Holland. Continuous inv"]
