摘要

目的:皮质醇是一种由下丘脑-垂体-肾上腺轴产生的糖皮质激素,在现代人类和非人类人群的唾液、血液和头发中被定期评估,作为应激暴露和应激反应的衡量标准。虽然最近的研究已经在现代和考古的恒牙组织中检测到了皮质醇的浓度,但本研究评估了人类乳牙的皮质醇浓度。材料与方法采用酶联免疫吸附法(ELISA)对9颗现代乳牙和10颗考古乳牙的51个牙本质和牙釉质样品进行皮质醇浓度测定。结果在来自现代和考古乳牙的32个牙本质样本中的15个和19个牙釉质样本中的8个样本中发现了可检测的皮质醇浓度。本研究是首次对乳牙组织中的皮质醇进行分析,证明了确定可测量浓度的潜力。分析乳牙的能力对于开发具有多种潜在未来应用的牙科皮质醇方法是不可或缺的,包括在骨骼中生物嵌入应力的研究。这项研究标志着一个更大的研究计划的关键一步,从生活和考古人群中研究初级牙列的压力。多个样品产生的皮质醇值无法用ELISA检测到。产生可检测的皮质醇水平可能需要最少数量的组织。未来的研究应扩大样本量,并考虑口腔皮质醇的内在生物学和外在保存因素。需要进一步的方法验证和评估牙齿皮质醇的替代方法。

Cortisol in deciduous tooth tissues: A potential metric for assessing stress exposure in archaeological and living populations

Objective

Cortisol is a glucocorticoid hormone produced by the hypothalamic-pituitary-adrenal axis that is regularly assessed in modern human and non-human populations in saliva, blood, and hair as a measure of stress exposure and stress reactivity. While recent research has detected cortisol concentrations in modern and archaeological permanent dental tissues, the present study assessed human primary (deciduous) teeth for cortisol concentrations.

Materials and Methods

Fifty-one dentine and enamel samples from nine modern and 10 archaeological deciduous teeth were analyzed for cortisol concentrations via enzyme-linked immunosorbent assay (ELISA).

Results

Detectable concentrations of cortisol were identified in 15 (of 32) dentine and 8 (of 19) enamel samples coming from modern and archaeological deciduous teeth.

Conclusions

This study is the first known analysis of cortisol from deciduous dental tissues, demonstrating the potential to identify measurable concentrations.

Significance

The ability to analyze deciduous teeth is integral to developing dental cortisol methods with multiple potential future applications, including research on the biological embedding of stress in the skeleton. This study marks a key step in a larger research program to study stress in primary dentition from living and archaeological populations.

Limitations

Multiple samples generated cortisol values that were not detectable with ELISA. Minimum quantities of tissue may be required to generate detectable levels of cortisol.

Suggestions for Further Research

Future research should include larger sample sizes and consideration of intrinsic biological and extrinsic preservation factors on dental cortisol. Further method validation and alternative methods for assessing dental cortisol are needed.

期刊介绍: Paleopathology is the study and application of methods and techniques for investigating diseases and related conditions from skeletal and soft tissue remains. The International Journal of Paleopathology (IJPP) will publish original and significant articles on human and animal (including hominids) disease, based upon the study of physical remains, including osseous, dental, and preserved soft tissues at a range of methodological levels, from direct observation to molecular, chemical, histological and radiographic analysis. Discussion of ways in which these methods can be applied to the reconstruction of health, disease and life histories in the past is central to the discipline, so the journal would also encourage papers covering interpretive and theoretical issues, and those that place the study of disease at the centre of a bioarchaeological or biocultural approach. Papers dealing with historical evidence relating to disease in the past (rather than history of medicine) will also be published. The journal will also accept significant studies that applied previously developed techniques to new materials, setting the research in the context of current debates on past human and animal health.
