The angulation that prisms obtain with the surface in human permanent teeth was analysed on broken enamel by means of the scanning electron microscope. In the cervical region the prisms end nearly perpendicular towards the surface, while the angle becomes more and more acute towards the occlusal region of the crown. In the cuspal area the deviation from the perpendicular direction of the prisms approaches 70 degrees. The size discrepancy between the inner and the outer surface of the enamel mantle can be explained by the more or less angulated position of the prisms.
通过扫描电子显微镜对人类恒牙牙釉质破损处棱柱与表面形成的角度进行了分析。在颈部区域，棱柱几乎垂直于表面终止，而朝着牙冠的咬合区域，该角度变得越来越尖锐。在牙尖区域，棱柱与垂直方向的偏差接近70度。釉质套的内表面和外表面之间的尺寸差异可以通过棱柱或多或少的成角位置来解释。
