A, B Representative Raman spectra taken from WT (black) and KI (red) mature incisal enamel. A. A spectral region containing major differences between WT and KI enamel from 1200 to 400 cm-1. B. A close up view of the three regions with most prominent differences. The most prominent and important difference is in 1071 cm-1 band, indicating an increase in carbonate level. There are also change in phosphate vibration regions at 620 – 570 cm-1 and 500 – 400 cm-1. C. Box plot of Vickers Hardness values for WT and KI erupted incisal enamel.
