Long-Term Impact of New Calcium-Silicate-Based Sealer on Mineral Contents and Crystallinity of Radicular Dentin: An Ex Vivo Study

Figure 1

Fourier transform infrared spectra of the dentin samples: the spectra of HiFlow-treated dentin, either stored in phosphate buffer solution (a and b) or deionized water (c and d) for 60 days, showed some changes in intensity and/or shift of amide I phosphate and carbonate bands (at 1720–1580 and 1200–900 and 890–830 cm⁻¹, respectively) compared with untreated dentin. No obvious change was observed in spectra of Sealapex-treated dentin.
