The directions of the enamel rods of all kinds of human permanent teeth were observed in the central perpendicular sections by using the so-called Schreger's bands as the marks of directions of rods bundles.
Results were summarized on a schematic illustration of Fig. 3, which showed the directions of rods in bucco-lingual and mesio-distal sections for each tooth kind. This will make a good practical reference for cavity preparation.
