Notes:
We have used synchrotron x-ray diffraction to study the crystal orientation in humandental enamel as a function of position within intact tooth sections. Keeping tooth sections intacthas allowed us to construct 2D and 3D spatial distribution maps of the magnitude and orientation oftexture in dental enamel. We have found that the enamel crystallites are most highly aligned at theexpected occlusal points for a maxillary first premolar, and that the texture direction varies spatiallyin a three dimensional curling arrangement. Our results provide a model for texture in enamel whichcan aid researchers in developing dental composite materials for fillings and crowns with optimalcharacteristics for longevity, and will guide clinicians to the best method for drilling into enamel, inorder to minimize weakening of remaining tooth structure, during dental restoration procedures
