From: Enamel apatite crystallinity significantly contributes to mammalian dental adaptations
The FTIR spectral differences of phosphate vibrations in the enamel apatite of the five fractions (differ in particle size) of three molar types (M1 to M3) in the series of tested pigs. (a) grinding curves the relation of IRSF against FWHM for three different molar types (each point represents the averaged value of five studied pigs.); (b) an example of the measured FTIR spectra used for the plotted parameters (FTIR spectra of five different fractions of second molar (M2) of 26 months old individual showing the variations in FWHM); c) IRSF boxplots of the finest fraction values obtained from all studied individuals.
