title: Prevalence and distribution of dental caries in a late medieval population in Finland.
abstract: The aim was to document the late medieval material and to compare the results with findings in other medieval populations and present-day Finns. The sample consisted of the remains of 410 individuals and included 4581 permanent and 600 deciduous teeth. Age determination was based on the stage of dental development and on the attrition pattern in the molar region. Scoring the presence and location of caries was done visually with the aid of a dental probe. In the younger age groups, caries was most prevalent in the occlusal fissures, but the proportion of cavities at these sites declined with age, possibly because occlusal attrition progressed more rapidly than did caries. In the permanent dentition, carious lesions were most frequently observed at the cementum-enamel junction, particularly on the approximal surfaces. The prevalence of caries was lower than among modern populations of similar ages. In addition, the relative distribution of caries was strikingly different, with root caries being the most common type.
