Mean FWHM of 960 cm−1 (phosphate peak width) before (0 Gy) and after (70 Gy) simulated radiotherapy at eight sites associated with the DEJ (4 buccal and 4 lingual sites; 5 spectra/site/tooth; n = 7 teeth): 500 μm into enamel (E-500); 30 μm into enamel (E-30); 30 μm into dentin (D-30); 500 μm into dentin (D-500). Error bars represent SD. *The peak width is significantly lower (P≤0.05) at both dentin sites following simulated radiotherapy.
