Introduction. Adequate radiopacity of endodontic sealers allows radiographic
visualization, assessment of root canal filling quality and its clinical
follow-up after obturation. The aim of our study was to evaluate the
radiopacity of Bio-Root RCS, MTA Fillapex, Bioceramic Root Canal Sealer,
GuttaFlow Bioseal in comparison to AH Plus sealer, as a gold standard in
clinical practice. Material and methods. Sealer specimens, 2 mm thick and 5
mm in diameter, were radiographed with an aluminum stepwedge using digital
imaging system. Radiographic densities of the specimens were shown as mean
greyscale values (Adobe Photoshop CS4 software) and expressed as mmAl/mm of
the material. ANOVA with a post hoc Tukey test was used, significance was
set at 0.05. Results. Differences in radiopacity between tested endodontic
sealers were statistically significant except the difference between BioRoot
RCS and GuttaFlow Bioseal. Conclusion. Radiopacities of all evaluated
calcium silicate-based sealers were higher than minimal values recommended
by standards. AH Plus sealer had the highest radiopacity, while calcium
silicate-based sealers showed lower values, from BioRoot RCS, followed by
GuttaFlow Bioseal, to MTA Fillapex, in descending order, and Bioceramic Root
Canal Sealer with the lowest values.
