增量牙本质分析利用不重塑的组织，并且允许在相同年龄下以高时间分辨率对婴儿期存活者与未重塑者进行比较。在这里，我们对伦敦一座 19 世纪墓地的牙齿进行了一项初步研究，比较了两种获得牙本质增量以用于随后同位素测定的方法的优点。 13C 和 15N 值的共变表明，即使很小的变化也有生理基础。我们表明，高分辨率牙本质内同位素谱可以精确定位短期事件，例如青少年时期的饮食变化或营养缺乏。
Incremental dentine analysis utilizes tissue that does not remodel and that permits comparison, at the same age, of those who survived infancy with those who did not at high temporal resolution. Here, we present a pilot study of teeth from a 19th-century cemetery in London, comparing the merits of two methods of obtaining dentine increments for subsequent isotope determination. Covariation in 13C and 15N values suggests that even small variations have a physiological basis. We show that high-resolution intra-dentine isotope profiles can pinpoint short-duration events such as dietary change or nutritional deprivation in the juvenile years of life.
