Cementochronology and its importance in forensic anthropology and bioarchaeology: a comparison between individuals of different climatic zones
Pytlíčková, Kristýna ; Brůžek, Jaroslav (advisor) ; Velemínský, Petr (referee)
In the field of forensic anthropology and bioarchaeology, there is a constant search for more suitable and reliable methods that would allow the estimation of age and seasonality at the time of death of individuals. This work is devoted to the method of cementochronology. It is a method that works with continuously growing dental tissue - a cement layer, whose regular periodic growth is closely correlated with increasing age. The diploma thesis is based on 2 sets of teeth of individuals of known age and extraction season, which come from different geographically different populations - Czech and Malaysian. The group of the Czech population contains a total of 21 teeth, the group of the Malaysian population contains 11 teeth. Histological specimens were prepared from these samples and 5 sections were analyzed from each individual, in which the incremental lines of the root cement layer were counted and the nature of the last incremental line to estimate seasonality. The results of age estimation achieved by us in both groups, the Czech and Malaysian populations, were close to the chronological age of the individual. The average difference between these ages in the samples of the Czech population was 1,15 years, with the results being overestimated more often. The average difference in the sample of...

Relationship between longevity and non-specific stress in the Early Medieval Moravian population
Zazvonilová, Eliška ; Brůžek, Jaroslav (advisor) ; Stránská, Petra (referee)
Opinions on the relationship between non-specific stress and age at death on adults are not uniform. The inspiration for our diploma thesis was a study by Croatian authors Becic et al. (2014) who reported that individuals with non-specific stress indicators (cribra orbitalia) lived longer. Our aims were following: to estimate the longevity and compared influence of used methods on the relationship between non-specific stress and age at death, to test the relationship between age at death and non-specific stress indicators, particularly cribra orbitalia and linear enamel hypoplasia, and also to test the relationship between non-specific stress indicators and stature. Methods for age estimation are divided into two parts, methods used in the study Becic et al. (2014) and our method selection chosen from the literature appropriate for the oldest individuals. In this study, the presence of cribra orbitalia and enamel hypoplasia was observed in 294 adult individuals (111 women, 135 men and 48 undetermined individuals) from the Early Mediaeval (9th - 10th century) Slavic skeletal series at Mikulčice (Great Moravia), IIIrd church. When comparing age at death estimated by two different technics we found reduced age at death for the individuals with cribra orbitalia and also with enamel hypoplasia. There...
