The human dental pulp was examined using a scanning electron microscope. The odontoblasts are pear-shaped and have a fine-grain surface structure. Tomes' process divides into fine branches before entering the predentin. Very few fibroblasts were found. These had stronger cell processes at the two terminal poles. Adhering to their surfaces were fine fibers. Collagenous and nerve fibers could not be accurately identified in the rich fibrillary network of the pulp. Stronger nerve fasciculi were readily observable through longitudinal sulci. Thinner fibers were seen to spread out in branches from some nerve bundles. The capillaries were observed to be surrounded by a sheath of fine fibrils.
使用扫描电子显微镜对人牙髓进行了检查。成牙本质细胞呈梨形,表面结构有细颗粒。托姆斯突在进入前期牙本质之前分成细支。发现的成纤维细胞很少。这些细胞在两个末端极有更强的细胞突起。其表面附着有细纤维。在牙髓丰富的纤维网络中无法准确识别胶原纤维和神经纤维。通过纵向沟很容易观察到较强的神经束。可见较细的纤维从一些神经束分支散开。观察到毛细血管被一层细纤维鞘包围。
