Ageing and dental attrition in a medieval rural Danish population

The rate of attrition on the permanent molars may depend on culturally and economically determined conditions of living. In order to analyse the relation the probability of having entered the stages of attrition is analysed by means of logistic regression on age at death. It is shown that not all teeth continue to be worn at the same rate throughout life and that there is an association between advanced attrition and risk of dying. The rate of dental attrition does not differ much by sex but there are some indications that male teeth are worn quicker than female teeth. This greater rate of attrition might be due to greater consumption of food in males than in females. The stages of dental attrition give some information on the age at death but they are poor age indicators on their own.
