Abstract
The morphology of the subodontoblastic region in the human dental pulp was analysed using the freeze-fracturing technique. Multiple areas of focal intercellular junctions were found between subodontoblastic fibroblasts (or Höhl's cells). The connections were of the gap junction type. Similar junctions were observed between subodontoblastic cells and small-calibre (0.10-0.20 microns) fibres, presumably nerves. Tight junctions were not observed.
摘要
采用冷冻断裂技术分析了人类牙髓中前期成牙本质细胞区域的形态。在前期成牙本质细胞性成纤维细胞（或赫氏细胞）之间发现了多个局灶性细胞间连接区域。这些连接为缝隙连接类型。在前期成牙本质细胞与小口径（0.10 - 0.20微米）纤维（可能是神经）之间也观察到了类似的连接。未观察到紧密连接。
