One hundred and fifty-six teeth were extracted from corpses aged between 15 and 79 years. Of these, 101 teeth were selected for measurement of the mineral content of the root by photon beam absorption. Six or seven cross-sections were measured in each root, and the mean values calculated for the apical, medial, and coronal part within each decade. Further, 20 selected teeth were embedded in methacrylate and the length of the zone of transparency determined in longitudinal sections. There was no significant age dependency of the root's mineral content. There was no correlation between the extent of transparency and the mineral content.
从15至79岁的尸体上拔除了156颗牙齿。其中，选取101颗牙齿通过光子束吸收法测量牙根的矿物质含量。每颗牙根测量6或7个横截面，并计算每个十年段内根尖、中部和冠部的平均值。此外，将20颗选定的牙齿嵌入甲基丙烯酸酯中，并在纵剖面中确定透明区的长度。牙根的矿物质含量与年龄无显著相关性。透明度与矿物质含量之间无相关性。
