Construction in the City of Baltimore during 1996 led to the recovery of human skeletal remains dating from 1792 to 1856. Historical research indicates that the skeletal remains come from two adjacent graveyards: Christ's Church Episcopalian Cemetery and the Potters Field East. The different socioeconomic status of the internees in each cemetery suggests the possibility of marked contrasts in lifestyle, health, and diet. To shed further light on these possibilities, analyses of microscopic wear patterns on teeth, or dental microwear analyses, were undertaken. A sample from Spanish Florida was used to help interpret the results. Epoxy casts of incisor and molar teeth were placed in an SEM and photomicrographs of clean wear facets were taken. The photomicrographs were digitized using the software package Microware 4.02. Statistical analyses of rank transformed data consisted of single-factor ANOVA, followed by post hoc tests. No significant differences were found between Christ's Church and Potters Field East samples for any of the variables examined in either molar or incisor teeth. However, differences between each Baltimore sample and the La Florida samples give suggestions of possible diet differences in antebellum Baltimore. The mosaic of differences between the Baltimore and La Florida samples probably reflects the wide variety of foods available to antebellum Baltimoreans as well as the relative lack of abrasives in their diet.
1996 年，巴尔的摩市的建筑工程导致了 1792 年至 1856 年期间人类骨骼遗骸的回收。历史研究表明，这些骨骼遗骸来自两个相邻的墓地：基督教堂圣公会墓地和波特斯菲尔德东墓地。每个墓地中被拘留者的不同社会经济地位表明，他们的生活方式、健康状况和饮食可能存在明显的差异。为了进一步阐明这些可能性，对牙齿的微观磨损模式进行了分析，即牙齿微磨损分析。采用来自西班牙佛罗里达州的样本来帮助解释结果。将门牙和磨牙的环氧铸型放入 SEM 中，并拍摄清洁磨损面的光镜照片。使用 Microware 4.02 软件包对光镜照片进行数字化。对秩变换数据进行的统计分析包括单因素方差分析，然后是事后检验。在磨牙或门牙中，任何变量的检查都没有发现基督教堂和波特斯菲尔德东样本之间有显著差异。然而，每个巴尔的摩样本与拉佛罗里达州样本之间的差异表明，在战前巴尔的摩可能存在饮食差异。巴尔的摩和拉佛罗里达州样本之间的差异可能反映了战前巴尔的摩人可获得的各种食物，以及他们饮食中相对缺乏磨料。
