The great potential of scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX) is in detection of unusual chemical elements included in ancient human dental calculus to verify hypotheses about life and burial habits of historic populations and individuals. Elemental spectra were performed from archeological samples of three chosen individuals from different time periods. The unusual presence of magnesium, aluminum, and silicon in the first sample could confirm the hypothesis of high degree of dental abrasion caused by particles from grinding stones in flour. In the second sample, presence of copper could confirm that bronze jewelery could lie near the buried body. The elemental composition of the third sample with the presence of lead and copper confirms the origin of individual to Napoleonic Wars because the damage to his teeth could be explained by the systematic utilization of the teeth for the opening of paper cartridges (a charge with a dose of gunpowder and a bullet), which were used during the 18th and the 19th century AD. All these results contribute to the reconstruction of life (first and third individual) and burial (second individual) habits of historic populations and individuals.
Thirteen samples of ancient human dental calculus were analyzed by scanning electron microscopy (SEM). Samples came from ten adults from the necropolis Znojmo-Hradiště which is dated to the Great Moravian period (the end of the 9th and beginning of the 10th century AD). SEM allowed observation and measurement of the excavated calculus objects with submicrometer resolution. Therefore it was possible to estimate plant/vegetable fibers and all bacterial morphological types like rods, cocci, spirals and filamentous forms. This confirms high oral bacterial diversity of medieval agriculturalists which is in agreement with recent molecular studies, but without destruction of samples and with lower costs. Presence of plant/vegetable fibers in dental calculus validated the vegetable part of the diet of early medieval Slavs found directly in excavated human skeletons.
