Radiotherapy Effect on Nano-mechanical Properties and ...
Results. The elastic modulus of enamel and dentin was significantly increased (P≤0.05) following radiation. Based on Raman spectroscopic analysis, there was a significant decrease in the protein to mineral ratio (2931/430 cm-1) following radiation at all sites tested except at D-500, while the carbonate to phosphate ratio (1070/960 cm-1) increased at E-30 and decreased at D-500.
