The electron microprobe analysis has been used to determine the concentrations of Ca and P in different regions of functional teeth in adult Salamandra salamandra (Amphibia, Urodela). Ca and P levels were found to be more elevated in the dentine shaft below the apex than in its basal part and in the pedicel. The concentrations are similar to those measured in teeth of higher vertebrates.
电子微探针分析已被用于测定成年火蝾螈（两栖纲，有尾目）功能牙不同区域的钙和磷浓度。结果发现，根尖下方牙本质小管中的钙和磷水平高于其基部和蒂部。这些浓度与在高等脊椎动物牙齿中测得的浓度相似。
