| Abstract: | AIM To compare the water solubility and its time associated tendency of 3 light cured composite resin (Durafill, Z100, Sculpt It) and to analyze the toxicity of the composites to human dental pulp cells. METHODS The water solubility was assayed according to national standards and the cyto toxical profile was analyzed with MTT assay. RESULTS The water solubility of all three composite materials occurred soon after they were immersed in water. The longer the immersion, the higher their solubility. The toxic rates of the 3 materials were in the following order: Z100
