In the radio opacity study, the cement mixture was poured into mold with 15 mm in diameter and 1 mm in thickness. Then the specimens were tested using a digital radiography apparatus. Using Digora for Windows software, radiopacity of the samples were evaluted.</span></span></span></span></span><br>
