Scanning acoustic microscopy (SAM) enables us to assess the tissue elasticity based on the propagation of sound speed. The aim of this study is to elucidate the change of the elasticity of mandibular condylar cartilage (MCC) and periodontal ligaments (PDL) by using SAM. SAM clearly visualized two-dimensional distribution of the sound speed changes of MCC and PDL. The sound speed of MCC and PDL increased significantly in the course of development. Collagens and Aggrecan were expressed in the MCC and PDL. SAM is a powerful tool for evaluating the elasticity and its distribution in tissues. These results suggested that the change of tissues was induced by morphological development such as the production and/or cross-link of collagens, and the functional development such as occlusal construction.

扫描声学显微镜（SAM）使我们能够根据声速的传播评估组织弹性。这项研究的目的是阐明使用SAM使用SAM的下颌do骨软骨（MCC）和牙周韧带（PDL）的弹性变化。 Sam清楚地表明了MCC和PDL的声速变化的二维分布。在开发过程中，MCC和PDL的音速显着提高。在MCC和PDL中表达胶原蛋白和脂肪蛋白。 SAM是评估组织中弹性及其分布的强大工具。这些结果表明，组织的变化是由形态学发育（例如胶原蛋白的生产和/或交联）引起的，以及诸如咬合结构之类的功能发展。
