Abstract: Aim: The aim of this study was to evaluate and compare the radiopacity of three different composite resins; one nanohybrid and two giomers. Material and Methods: For evaluation of radiopacity of composites, ten specimens of each material [(3 groups) (total 30) (n=10] with thicknesses of 2 mm were prepared and radiographed alongside aluminum step wedge and human enamel and dentin. Occlusal radiograph was taken and mean gray values of the test materials were measured using Image J software. Then a conversion was performed to establish the radiopacity of the test materials, in millimeters of equivalent Aluminum (Al). Data were analyzed using one‑way analysis of variance and Scheffe’s Post Hoc tests (P < 0.05). Results: The radiopacity values varied among the restorative materials (p < 0.05) with the highest for Filtek followed by Beautifil Injectable, Beautifil 2, enamel and dentin. Conclusion: All materials tested had radiopacity values greater than dentin and had sufficient radiopacity to meet International Organization for Standardization 4049 standard. Key Words: Radiopacity, aluminum stepwedge, composites, opacifing-fillers.
