牙齿修饰，特别是牙齿嵌体，是古代中美洲最具特色的生物文化传统之一。这份简短报告的主要目的是确定位于危地马拉南太平洋海岸的雷诺萨考古遗址中用于制作牙科嵌体的原材料。最近发现的一个大规模的埋葬，大约在中晚期前古典时期（公元前500年至公元前200年），把网站在聚光灯下。在中美洲发现了一些最早的牙齿结壳载体，这代表了镶嵌传统的开始。用于测定原材料的分析方法是扫描电子显微镜（SEM）和X射线光谱法。经鉴定，原材料为黄铁矿和赤铁矿。这些发现开启了对这些材料在这千年传统中的获取和使用的新关注。
Dental modifications, especially dental inlays, were one of the most characteristic biocultural traditions in Ancient Mesoamerica. The main objective of this brief report is to identify the raw material used to elaborate dental inlays in the archaeological site of Reynosa, located in the Southern Pacific Coast of Guatemala. The recent discovery of a massive burial, dated roughly in the Middle-Late Preclassic Period (500 BC–200 BC), put the site in the spotlight. There were found some of the earliest carriers of dental incrustations in Mesoamerica, which represent part of the beginning of the inlay tradition. The analytical method used to determine the raw material was scanning electron microscopy (SEM) with X-ray spectroscopy. The identified raw materials were pyrite and hematite. These findings have opened new concerns about the obtaining and the usage of those materials in this millennial tradition.
