Growth of human dentine was investigated in extracted permanent teeth exhibiting more than two tetracycline lines. It was concluded that: (1) The secretory activity of an odontoblast varies considerably during its life cycle, and likewise the rate of migration of the odontoblast cell body varies. Odontoblast secretion and migration as a general rule start slowly, reach a peak and then slow up as dentine production nears completion. (3) The activity of a particular odontoblast varies with the type of tooth with which it is associated and with its position within the tooth, as well as with the particular stage reached in its life cycle.

对具有两条以上四环素标记线的拔除恒牙中的人牙本质生长情况进行了研究。得出以下结论：（1）成牙本质细胞的分泌活动在其生命周期中变化很大，同样，成牙本质细胞胞体的迁移速率也会变化。一般来说，成牙本质细胞的分泌和迁移开始时缓慢，达到峰值，然后随着牙本质生成接近完成而减缓。（3）特定成牙本质细胞的活动因其所关联的牙齿类型、在牙齿内的位置以及其生命周期中所达到的特定阶段而有所不同。
