Stable isotope analysis of sequential dentine samples is a potentially powerful method to reveal insights into early life‐histories of individuals in the past. Dentine incremental growth structures are complex, however, and current approaches that apply horizontal sectioning of demineralized tooth halves or quarters risk combining multiple growth layers and may include unwanted cementum or secondary dentine. They also require destruction of large parts of a tooth. Here, we present a less destructive and relatively straightforward protocol that reduces damage, increases temporal resolution, and improves the accuracy of age‐alignment between individuals.

人类牙齿同位素序列的解剖学敏感的牙本质显微采样和年龄校正方法指南。

对连续的牙本质样品进行稳定的同位素分析是揭示过去个人早期生命史的有力方法。但是，牙本质的增量生长结构很复杂，目前应用水平脱盐的牙齿半部或四分之一牙齿的方法可能会合并多个生长层，并且可能包含不需要的牙骨质或次级牙本质。它们还需要破坏牙齿的大部分。在这里，我们提出了一个破坏性较小且相对简单的协议，该协议减少了损害，提高了时间分辨率，并提高了个体之间年龄对齐的准确性。
