在以前的一系列研究中，我们阐明了哺乳动物牙齿中小管周围基质的存在和分布、结构和组织化学性质的某些方面。观察主要限于冠状牙本质，选择马牙作为光学水平观察的主要材料来源，2' 5，6因为管周基质在冠状牙本质中比在根状牙本质中更明显，并且因为马牙中的管周基质比人牙中的管周基质大，用于电子显微镜。因此，这些研究缺乏系统的材料整理，我们将管周基质发育阶段的许多方面留待将来研究。本报告主要涉及人冠根牙本质形成和成熟阶段的管周基质。在成熟的牙根牙本质中，硬化的透明牙本质被研究作为对可能发生在管周基质中的年龄变化的初步观察。
In a series of previous studies,'-6 we clarified some aspects of the presence and distribution in mammalian teeth, the structure, and the histochemical nature of the peritubular matrix. Observations were mainly limited to the crown dentin, and horse teeth were selected as main source of material for observation in the optical level,2' 5, 6 because the peritubular matrix appears more strikingly in crown dentin than in root dentin and because it is larger in horse teeth than in human teeth, which were used for electron microscopy.' 3, 4These studies, therefore, have lacked systematic arrangement of materials, and we have left many aspects of the developmental phase of the peritubular matrix to future research. The present report is primarily concerned with the peritubular matrix in human crown and root dentin in formative and mature stages. In mature root dentin, the sclerosed transparent dentin was studied as a preliminary observation on age changes that might occur in the peritubular matrix.
