Small angle X-ray scattering (SAXS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) have been used to look at enamel from nine premolars, three each from individuals in low, medium and high risk caries groups. Only SAXS was able to detect consistent differences between any of the groups. In enamel from the high caries risk group, the micropores between the hydroxyapatite crystals were laminar. In enamel from the low caries risk group, the micropores were cylindrical. Other parameters varied between teeth but were not correlated with caries risk.
小角X射线散射（SAXS）、X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）已被用于研究9颗前磨牙的牙釉质，每组3颗，分别来自低、中、高龋齿风险组的个体。只有SAXS能够检测到任何组之间的一致差异。在高龋齿风险组的牙釉质中，羟基磷灰石晶体之间的微孔呈层状。在低龋齿风险组的牙釉质中，微孔呈圆柱形。其他参数在不同牙齿之间有所变化，但与龋齿风险无关。
