Progress and perspectives of the isotope research of human tooth enamel

doi:10.16359/j.1000-3193/AAS.2024.0019

Abstract

Abstract:

This paper meticulously addresses the significant theoretical and methodological aspects involved in isotopic investigations of human tooth enamel. Firstly, it systematically organizes the growth and development mechanism, principal chemical composition, and the efficacy of human tooth enamel in withstanding diagenesis. Emphasis is placed on the inherent advantages that have rendered it the primary target for hydroxyapatite isotope analyses and studies within the current bioarchaeological realm. Secondly, a vast array of research topics centered around the multi-isotope analysis of elements such as oxygen (δ¹⁸O), carbon (δ¹³C), strontium (⁸⁷Sr/⁸⁶Sr), zinc (δ⁶⁶Zn), magnesium (δ²⁶Mg), calcium (δ^44/42Ca), and lead (Pb) in human enamel are distilled and consolidated into three scientific themes: human life history, habitation, and health. Additionally, the current status of each of these research areas is comprehensively reviewed. Finally, within the framework of constructing the theoretical system of archaeology with Chinese characteristics in the new era, the exigency of the swift advancement of multi-isotope research on tooth enamel is underscored. In light of the existing research experiences and deficiencies in the international bioarchaeology community, future research in China is anticipated to progress from the vantage points of innovating experimental sampling strategies and research methodologies, accurately discerning the merits and demerits of diverse mass spectrometry techniques, broadening the depth and scope of research topics, and delving deeply into the cooperative interactions between isotopes and different human body tissues.

Key words: enamel, multi-isotope, growth and development, chemical constitution, diagenesis
