Medieval finds made from leather with human teeth impressions (finds from Pereyaslavl Ryazanskiy)

The paper deals with materials from medieval Pereyaslavl Ryazanskiy containing impressions of human teeth. The examination of characteristics of these impressions under a microscope revealed several types of such impressions. The teeth mainly left indentations during the technological process. Working with leather, an artisan held leather in his mouth with his teeth which he also used to scrape, stretch and chewed leather. The paper provides results of stomatological analysis of indentations left by the teeth surface on leather goods.
