Abstract
The dentin surface of human tooth crown was observed by means of scanning electron microscope and the following results were obtained. 1. Very clear picture of shallow depressions (foveola eburnea, Dentinfurche) showing fine network structure was obtained by lower magnification which demonstrated markedly different patterns in size and shape of respective depression according to the difference of tooth kinds used and sites of the crown observed. 2. By the use of higher magnification, not only came smaller depressions that subdivided each depression in sight, but also the presence of numerous pits that further subdivided the smaller depression and were presumed to be remnants of ameloblasts (Tomes' processes) was confirmed lying among complicated bundles of Ebner' fibrils.
