Dental calculus (tartar, or calcified dental plaque) is caused by precipitation of minerals from saliva and gingival crevicular fluid in plaque. It is found in all known human populations. Scanning electron microscopy (SEM) gives a lot of information about human diet, oral bacterial flora and the habits of our ancestors. Energy dispersive X-ray spectroscopy (EDX) brings information about the inorganic elemental composition of the calculus. The main elements in dental calculus are calcium, phosphorus, magnesium, fluoride and carbon dioxide. Other special elements are supposed to come from other sources. A study performed by Charlier (Charlier et al. 2010) confirmed various individual elemental compositions of dental calculus from the Etruscan-Celtic necropolis. In this study, we want to distinguish soil contamination from elements which come from calculus (which are special for the individual). We continue in our previous study (Fialova et. al. 2016) to recognize elements from external environment which can affect the results of authentic composition of dental calculus. A sample of dental calculus came from a 20-29 year old female from the burial site Kopčany Kačenáreň (from the 9th-10th century, Slovak Republic). For the SEM-EDX analysis, a SEM Magellan 400 (FEI) equipped with an ED APOLLO X Silicon Drift Detector (EDAX) was used.).
