用几种高分辨率分析技术对咸水鳄齿的结构和组成进行了表征。X射线衍射结合元素分析和红外光谱分析表明，牙齿的矿物相为碳酸化的缺钙纳米晶羟基磷灰石，在牙本质、牙釉质和牙骨质三种组织中都存在。三种组织中的氟化物含量都很低(
Structure and composition of teeth of the saltwater crocodile Crocodylus porosus were characterized by several high-resolution analytical techniques. X-ray diffraction in combination with elemental analysis and infrared spectroscopy showed that the mineral phase of the teeth is a carbonated calcium-deficient nanocrystalline hydroxyapatite in all three tooth-constituting tissues: Dentin, enamel, and cementum. The fluoride content in the three tissues is very low (
