Long-Term Impact of New Calcium-Silicate-Based Sealer on Mineral Contents and Crystallinity of Radicular Dentin: An Ex Vivo Study
Table 1
Mean ± standard deviation values of all parameters extracted from FTIR spectra of all investigated dentin stored in either phosphate buffer solution or deionized water for 60 days; these parameters include integrated area under bands of amide I, phosphate, carbonate (at 1720–1580, 1200–900, and 890–830 cm−1), and phosphate/amide I and carbonate/phosphate ratio.
