Figure 2 The X-ray microdiffraction Debye ring patterns and diffractogram of the healthy tooth. The Debye rings of positions 1, 2 and 3 in the dentin and EDJ (A, B, C) were intact and continuous. The Debye rings of positions 4, 5 and 6 in the enamel (D, E, F) were not intact and discontinuous, suggesting a texture effect or preferred orientation of these zones. (G) The X-ray microdiffractogram of the natural healthy tooth at different points: 1-6 indicate the diffractogram of points 1-6.
