软纤维结缔组织内卷曲的存在在决定组织的生物力学特性方面具有相当大的作用。然而，很少或没有关于胶原蛋白在人类颞下颌关节卷曲的信息。为了补救这种情况，任何卷曲的存在和性质进行了研究，在部分人颞下颌关节的年龄从4.5-63岁之间，使用偏振光显微镜和微分干涉显微镜。在关节盘内以及下颌窝和下颌髁突的关节面内的胶原中寻找卷曲的存在。通过偏振光，在所有研究年龄的所有三种组织中均观察到卷曲。从放大到x250的显微照片的定量显示，条带的周期性（代表完整卷曲波的一半）具有在约15-20 μ m之间变化的平均值。还通过微分干涉相差显微镜直接观察到微泡化。在解释颞下颌关节的正常功能时，需要考虑这种基本特征的存在。(C)2000爱思唯尔科技有限公司版权所有。
The presence of crimping within soft fibrous connective tissues has a considerable role in determining the biomechanical properties of the tissue. However, there is little or no information on crimping of collagen in the human temporomandibular joint. To remedy this situation, the presence and nature of any crimping was studied in sections of human temporomandibular joints from individuals varying in age from between 4.5-63 years, using polarized light microscopy and differential interference contrast microscopy. The presence of crimping was looked for in collagen within the intra-articular disc and the articular surfaces of the mandibular fossa and mandibular condyle. By polarized light, crimping was seen throughout all three tissues at all ages studied. Quantification from micrographs enlarged to x250 showed that the periodicity of the banding (representing half a complete crimp wave) had a mean varying between about 15-20 mu m. Crimping was also directly visualized by differential interference contrast microscopy. The presence of such a fundamental feature needs to be considered when explaining the normal function of the temporomandibular joint. (C) 2000 Elsevier Science Ltd. All rights reserved.
