The samples and aluminum step wedge used as standard for radiologic analysis were placed on X-ray sensor. They were digitally radiographed together and the digital radiographic images were then analyzed with ImageJ program. The relationship between the gray value for each specimen and the aluminium step wedge thickness were plotted and transferred. The data were analyzed by One-way ANOVA and Tukey’s post-hoc test at p&lt;0.05. Zinc phosphate cement showed the highest radiopacity value among 10 dental cement groups. For the resin cements, Nexus 3 demonstrated the highest radiopacity value followed by Variolink® Esthetic LC which was no statistically significant difference to Variolink® Esthetic DC, Panavia V5 and Panavia SA luting. Moreover, Rely™ X Veneer was the lowest radiopacity value but it was no statistically significant difference to Rely™ X Ultimate Clicker. However, Superbond C&amp;B and Temp-Bond Clear showed radiolucent. In conclusion, there were statistically significant among 10 groups of cement in which zinc phosphate cement showed the highest radiopacity value.</p> ER -
