Hydration Characterization of Two Generations of MTA-Based Root Canal Sealers

Since the setting characterization of a root canal sealer has an impact on its biological behavior final obturation, this study evaluated mineral trioxide aggregate MTA-Fillapex versus MTA-Bioseal compared with epoxy resin (Adseal) sealers. Freshly mixed was inserted into mold (n = 10). The initial and times were using Vicat needle then statistically analyzed by one-way ANOVA at p < 0.05. raw pastes stages reaction Fourier Transform Infrared (FTIR) Spectroscopy. phase compositions X-ray diffraction (XRD). A significant fast time recorded Adseal (4.7 ± 0.46 h) followed (11.4 1.34 0.001. did not set completely in three months. FTIR XRD both detected bands polymerized phases, while those partial polymerization low percentage silica. met ISO standards for times. However, fulfill ideal requirement sealer. Although MTA-sealers had nearly similar compositions, they behaved differently during hydration reaction. completely, set.
