Abstract | Human dental cementum was analyzed by electron paramagnetic resonance (EPR). The measured EPR powder spectra of gamma-irradiated enamel. Both spectra were characterized by the same line shapes and g values. The position of the extrene frst derivate ieaps can be described bu g1=2.0023 and g2=1.9971+-0.002, and are assignable to the CO3-/3 center. The angular dependence of the cementum EPR spectra indicates a different arrangement of the hydroxyapatite microcrystals compared to that of enamel. A corresponding model of cementum microcrystal alignment has been proposed. The methodology presented can be utilized for studying the mineralization process of root cementum and other mineralized tissues. | |
