Rat incisor dentin was studied by an x-ray micro-Laue method to investigate the relationship between crystal orientation and structural variation in the dentin. The results showed that crystal orientation was very poor in the labial dentin, but that the crystals were well-oriented in the lingual dentin. In the lingual dentin, the axis of crystal orientation was parallel to the tooth axis. It is suggested that the difference in crystal orientation between the lingual and labial dentin is due to the different mode of calcification between the two.
采用X射线微劳厄法对大鼠切牙牙本质进行研究，以探讨牙本质中晶体取向与结构变化之间的关系。结果表明，唇侧牙本质中的晶体取向很差，但舌侧牙本质中的晶体取向良好。在舌侧牙本质中，晶体取向轴与牙轴平行。提示舌侧和唇侧牙本质晶体取向的差异是由于两者钙化方式不同所致。
