Slightly etched prisms of human dental enamel surfaces were examined in the scanning electron microscope. The crystals in the central region of prisms showed a denser arrangement, similar to the crystals on the periphery, which determine their form here. A crevice-like space could be observed between the central and the peripheral region of a prism. The prisms on the enamel surface showed a wide variety in shape being either of fish-scale or key-hole form, in other places fully irregular. There was no uniform prism on a single tooth, and an interprismatic substance was never found. On the surface of a deciduous tooth a prismless enamel surface was observed consisting of edges of crystallites, which did not unite to prism formation.
在扫描电子显微镜下检查了人类牙釉质表面轻微蚀刻的棱柱体。棱柱体中心区域的晶体排列更密集，类似于周边区域的晶体，周边区域的晶体决定了棱柱体在此处的形态。在棱柱体的中心区域和周边区域之间可以观察到一个缝隙状空间。牙釉质表面的棱柱体形状多种多样，有鱼鳞状或钥匙孔状，在其他地方则完全不规则。单颗牙齿上不存在统一的棱柱体，并且从未发现柱间质。在乳牙表面观察到一个无棱柱体的牙釉质表面，其由微晶边缘组成，这些微晶边缘未结合形成棱柱体。
