The present study aimed at evaluating the radiopacity ofBiodentine™ and Pro Root MTA as root end filling materials using a digitalradiography technique.Materials and Methods: Specimens of BiodentineTM and Pro Root MTA testmaterials with 1mm thick and 10 mm internal diameter were prepared for digitalradiographic analysis using an aluminum washer. The radiopacity of theBiodentine™ and Pro Root MTA was assessed using dental radiographyequipment in combination with a phosphor plate digital system and a grey scalevalue aluminum step wedge with thicknesses varying from 1 mm to 10 mm insteps of 1 mm each. The degree of radiopacity of the test materials wereradiographed and compared together with the aluminum step wedge on acomputer screen using image J software. Radiopacity was expressed in mm ofequivalent aluminum step wedge. The radiopacity values of Biodentine™ and ProRoot MTA were statistically analyzed using the one way analysis of variance(ANOVA) and post-hoc test (Bonferroni test), the level of significance was set at0.05 (P<0.05). Results: The radiographic data showed that the degree ofradiopacity of Pro root MTA is significantly higher than that of Biodentine™(P<0.001). The current study reported that the ProRoot MTA showed requisiteradiopacity around 5.86 mm when compared with aluminum step wedge steps,whereas the radiopacity of Biodentine™ determined around 2.46 mm ofequivalent aluminum.Conclusion: The radiopacity of Pro Root MTA is clinically relevant that allows forclear distinction between the material and the surrounding tooth structure enablingit to be used as root end filling material. However, Biodentine showed reducedradiopacity that needs further improvement.
