用光镜和电镜观察了大鼠磨牙不同发育阶段的主要纤维和细胞牙骨质，并对其发育和结构进行了研究。随着根系的发育，主纤维的厚度逐渐增加。在任何阶段，主纤维均由骨骨质表面的小纤维束组成，呈分支结构。Sharpey的纤维也表现出类似的分支结构，厚度增加，从表面上可以看到骨质。结果表明，主要纤维的厚度增加是由于纤维束的聚集。根据纤维排列的不同，细胞牙骨质的发育分为早期和晚期两个阶段。早期的牙骨质被认为含有少量的夏普纤维和许多随机排列的内在纤维。晚期骨质含有较粗的有分支的Sharpey’s纤维和内在纤维，它们似乎环绕着Sharpey’s纤维并/或在其中蜿蜒。
The principal fibers and cellular cementum were examined in various developmental stages in rat molars by light and electron microscopy, and their development and structure were studied. The principal fibers increased in thickness with root development. At any given stage, the principal fibers consisted of small fiber bundles on the cementum surface and showed a branching structure. Sharpey's fibers also showed a similar branching structure and increased in thickness, as traced superficially in the cementum. It was suggested that the principal fibers increased in thickness by means of the aggregation of fiber bundles. The development of cellular cementum was divided into two (early and late) phases on the basis of the fiber arrangement. The early cementum was believed to contain a few Sharpey's fibers and many randomly arranged intrinsic fibers. The late cementum contained thicker Sharpey's fibers with branches and the intrinsic fibers which appeared to encircle Sharpey's fibers and/or meander among them.
