Aim: the purpose of this study was to evaluate the radiopacity of different filling materials, using resources of digital radiography in a human tooth model. Methodology: seventy extracted single-rooted human teeth were selected, the coronal access was performed, and the working length was established 1 mm short of the foramen. After chemo-mechanical preparation the teeth were divided into 7 groups (n = 10) according to the filling material used: G1 Epiphany, G2 AH Plus, G3 EndoRez, G4 EndoFill, G5 Endomethasone, G6 Sealapex and G7 Sealer 26. In the G1 Epiphany system, Resilon cones were used; however, in all other groups gutta-percha cones were used. After seven days of storage, digital radiographs were taken to assess the results. To evaluate the radiopacity, the digital software DBSWIN generated a colorimetric graphic for each sample, correlating the color gradient observed in the sample with a corresponding numerical score. The data were statistically analyzed by ANOVA and Tukey's test at 5% significance level. Results: the system Epiphany / Resilon was statistically superior to the AH Plus, EndoRez, Sealapex and Sealer 26 groups associated with gutta-percha in terms of radiopacity (P <0.05). Conclusion: the root canal sealer Epiphany, associated with Resilon cones, showed the highest values of radiopacity.
