牙釉质的体积和表面积随着与牙本质-牙釉质交界处的距离而增加，特别是在牙尖处，而杆的数量保持不变。体积的增加可能是由于牙齿表面附近的杆直径增加、Hunter-Schreger带的异区方向中的杆的周向缠绕以及杆从牙本质表面处的中冠状起源到牙齿表面处的尖突终止的迁移。增加的表面积可以通过增加的杆直径和杆倾斜接近牙齿表面来解释。
Enamel increases in volume and surface area with distance from the dentin-enamel junction, particularly at cusps, while the number of rods remains constant. The increase in volume may be due to the increased rod diameter near the tooth surface, a circumferential winding of rods in the parazone orientation of Hunter-Schreger bands, and the migration of rods from a mid-coronal origin at the dentin surface to a cuspal termination at the tooth surface. Increased surface area can be explained by the increased rod diameter and the oblique approach of rods to the tooth surface.
