The authors investigated the cariosity of the teeth on the bone remains of the Slavonic inhabitans. These skeletons are dating to the 9th and 10th centuries and coming from the burial site at Olomouc-Nemilany.A total of 794 teeth were appraised and 933 dental alveoli were examined. The intensity of cariosity of the permanent dentition was proved to be about 20.8% and the frequency of the dental caries reached up to 72.9%. These two values were higher in the women. From the different types of teeth, most of dental caries was found on molars.
