Previously described giant tubules in human and red deer coronal dentin have been subjected to a study by polarized light microscopy. Structure of the giant tubules was similar in both species. The lumen of each tubule was bordered by a 5-15-micrometers-thick collagenous mantle in which the fibers were orientate parallel to its long axis. In a circular dentin area encompassing the mantle, the course of the collagen fibers might be characterized as a winding of fibers around the cylindrical mantle. This structure of the giant tubules conforms with that described earlier in the rudimentary maxillary canine of a red deer. Thus, such tubules do not represent a rare anomaly, but occur regularly in both human and red deer coronal dentin.
先前在人类和马鹿冠状牙本质中描述的巨大牙本质小管已通过偏光显微镜进行了研究。两种物种中巨大牙本质小管的结构相似。每个小管的管腔由一层5 - 15微米厚的胶原质套膜界定，其中的纤维平行于其长轴排列。在包含该套膜的圆形牙本质区域，胶原纤维的走向可描述为围绕圆柱形套膜的纤维缠绕。这种巨大牙本质小管的结构与先前在马鹿的乳上颌尖牙中描述的结构相符。因此，这种小管并非罕见的异常情况，而是在人类和马鹿的冠状牙本质中都有规律地出现。
