The X-ray microdiffraction Debye ring patterns of the carious tooth. (A) Outside the cavity the Debye rings were discontinuous but distinct on the whole. (B) Inside the cavity the Debye rings were continuous but indefinite, suggesting that the crystals were destroyed. (C) The X-ray microdiffractogram of the carious tooth. 1: inside the cavity, peaks in the interval from 10° to 40° disappeared with high background, suggesting that caries destroys the apatite crystal into an amorphous substance. 2: outside the cavity, the whole diffractogram was similar to the healthy tooth.
