Abstract

Scanning electron microscopy of the enamel organ of rat incisor and molar teeth in the maturation stage of amelogenesis revealed two vascularization patterns of the papillary layer. In one pattern, the anastomosing capillaries formed loops of varying sizes around spherical or somehwat oblong papillae. In the second pattern, the capillaries were parallel to each other embedded in furrows between long ridges of papillary cells. It is postulated that each of these two patterns may be associated with a specific stage in the process of enamel maturation.

摘要

在釉质形成成熟阶段对大鼠门齿和臼齿的成釉器进行扫描电子显微镜观察,发现乳头层存在两种血管化模式。在一种模式中,吻合的毛细血管围绕球形或略呈长方形的乳头形成大小各异的环。在第二种模式中,毛细血管相互平行,嵌入乳头细胞长嵴之间的沟中。据推测,这两种模式中的每一种都可能与釉质成熟过程中的特定阶段相关。
