The odontoblasts showed remarkable differences from the apical to the incisal end. Near the apical end of the tooth, "immature odontoblasts”, which were thought to be involved in the formation of the mantle dentin, were arranged in a single layer, and continuous capillaries were located just beneath the odontoblasts. In the middle of the tooth, "mature odontoblasts” with highly developed cell organelles and notable processes formed a pseudostratified layer; fenestrated capillaries were found between these cells close to the predentin. The height of the odontoblast layer and the rate of dentin deposition on the labial (enamel-related) side was significantly greater than that on the lingual (cementum-related) side. Near the incisal end, cementum-related odontoblasts gradually decreased in height and number to become "post-odontoblasts” that produced atubular dentin; continuous capillaries were located subjacent to the post-odontoblasts. On the labial (enamel-related) side, however, odontoblasts retained their pseudostratification; fenestrated capillaries were still observed in the odontoblast layer. No atubular dentin was formed on the labial side.
