The most highly differentiated cells of the dental pulp - odontoblasts, taken from normal and carious teeth of persons of various age groups were investigated by the aid of electron microscope. Aim of the investigation to determine the relationship between the fine structure and function. Ultrastructural investigation shows that odontoblasts beside the 1) production of dentin take part in the 2) transport of substances and 3) tissue fluids. In the beginning and continuous promoting of the 4) crystallization of the enamel layers odontoblasts play a role of a border-surface which provide a necessary concentration 5) On the end part of nerve fibres they may function as supporting cells (replacement of the Schwann-cells). 6) When pathological processes present (caries) the ultrastructure shows cell-activity of defence type.
借助电子显微镜对取自不同年龄组人群正常牙齿和龋牙的牙髓中分化程度最高的细胞——成牙本质细胞进行了研究。研究目的是确定精细结构与功能之间的关系。超微结构研究表明，成牙本质细胞除了1）形成牙本质外，还参与2）物质运输和3）组织液的运输。在釉质层4）结晶的起始和持续促进过程中，成牙本质细胞起到边界表面的作用，提供必要的浓度5）。在神经纤维的末端部分，它们可能充当支持细胞（替代雪旺细胞）。6）当出现病理过程（龋齿）时，超微结构显示出防御型细胞活性。
