      Background: released monomers to the oral environment from dental composite, cause systemic or local side effects on the tissues and cells and also affect mechanical properties of the resins.Methods: This study evaluated the effect of the volume and renewing of storage media on monomer leachability from dental composite. Samples of two dental composites (BEAUTIFIL II Gingiva (BG) and Filtek bulkfill flowable (FBF)) were stored after polymerization in 1 and 3 milt storage media (ethanol/water 75%) for seven days. Refreshing of storage media was done in half of the samples of each group. The amount of releasing monomers (UDMA, BisGMA, TEGDMA) in storage media were measured by high performance liquid chromatography. (HPLC) Data was analyzed using Two-way ANOVA and T-test. (α=0.05).Results: Elution of TEGDMA and UDMA from both composites was significantly higher in 3ml storage media. In groups with refreshing of storage media, BisGMA had higher amounts of release. Saturation makes the storage media volume important factor in monomer elution. Conclusion: Refreshing of storage media had significant effect on monomer release before the elution of 50% of total released monomer.
