An attempt has been made to characterize the nature of the unidentified cell processes participating in gap junctions in the odontoblast layer. In peripheral and pulpal nerves, there is a strong relationship between together with the ratio of microtubules to microfilaments, has been measured and compared for four types of cell processes found in the dental pulp, including those participating in gap junctions. The processes taking part in the gap junctions cannot be distinguished from pulpal axons on the basis of microtubule-to-microfilament ratio nor on the relationship between microtubule and microfilament population and process caliber. While these findings do not prove that the "gap members" are nerve fibers, it does support the hypothesis that the processes taking part in gap junctions in the peripheral dental pulp are nerve fibers.
人们试图描述成牙本质细胞层中参与缝隙连接的未识别细胞突起的性质。在周围神经和牙髓神经中，微管与微丝的比例之间存在密切关系，并且已经对牙髓中发现的四种类型的细胞突起进行了测量和比较，包括那些参与缝隙连接的细胞突起。基于微管与微丝的比例，以及微管和微丝数量与突起口径之间的关系，无法将参与缝隙连接的突起与牙髓轴突区分开来。虽然这些发现并不能证明“缝隙连接成分”是神经纤维，但确实支持了这样一种假设，即参与牙髓外周缝隙连接的突起是神经纤维。
