Abstract

The distribution of fluoride across human cementum has been determined on 59 individual teeth taken post mortem from five subjects aged 30, 43, 54, 66 and 70 years. Eight teeth of different types were examined from each of the five subjects together with a further 19 teeth from the 54-year-old, making a total of 27 teeth from this subject. As in a previous study, F concentrations were generally higher towards the surface of the cementum, but there were considerable variations between F gradients. The teeth from each subject seemed to comprise a family of profiles, characteristic of the individual.

摘要

已对从五名年龄分别为30岁、43岁、54岁、66岁和70岁的受试者尸体上获取的59颗单颗牙齿，测定了氟在人牙骨质中的分布情况。从这五名受试者中每人选取八颗不同类型的牙齿进行检查，另外从54岁的受试者中选取了19颗牙齿，该受试者共有27颗牙齿接受检查。与之前的一项研究一样，牙骨质表面的氟浓度通常较高，但氟梯度之间存在相当大的差异。每个受试者的牙齿似乎都构成了一组特征曲线，具有个体特异性。
