title: [Evaluation of the dental pathology in archaeological skeletal material: prevalence of dental caries since prehistory to modern age].
abstract: The evaluation of the dental health of past populations is an important part of the anthropological analysis of human skeletal remains uncovered during the archaeological excavations. The results provide the important information not only of the overall health of past populations, but also are reflective of the nutrition or the social status of our ancestors. We focused on the comparison of dental caries from prehistoric times to the present day. The aim was to evaluate the dental decay in several prehistoric, Early Medieval and modern populations and determine whether and to what extent the decay differ between the individual groups. METHODS AND RESULTS. We observed the permanent dentition in adult men and females, who were divided into three groups: the population of the younger Eneolithic to the Bronze Age, the population of the Early Middle Ages and the population of the modern times. We used the Index of Intensity of Caries I-CE and the Index of Caries Frequency F-CE to evaluate the incidence of caries and intra-vital losses. The comparison was carried out between groups, between both of jaws and between individual teeth. We took into account sex and age of the individuals studied. The highest value of F-CE was set in the population of the modern times (67.5). The difference in caries frequency among populations was not significant. The intensity of caries was the highest in modern population (I-CE: 13.2). Compared with the two older populations the difference was statistically highly significant (p 0.001).With regard to sex, the results differed between populations. It could be caused by a different frequency of men and females in individual groups.The correlation of intensity of caries with age was confirmed. Some partial results were affected by unequal frequency of age categories. CONCLUSION. The results showed the worst dental health in the population of the modern times. The null hypothesis,that tooth decay among the individual populations from different periods is not different, was rejected. The results must be interpreted with regard to the demographic composition of the files researched.
