Radiopacity of calcium silicate-based endodontic sealers using digital imaging

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