Caries prevalence in the dentition of a late eighteenth century population

Remains of 92 individuals of known age and a further 71 of unknown age were selected from nearly 1000 skulls exhumed from the crypt of Christ Church, Spitalfields. Ante- and post-mortem tooth loss was assessed and caries prevalence and distribution were studied. Post-mortem loss of teeth was highest in the oldest age group, suggesting that greater care is needed during exhumation to minimize this loss. Juvenile caries levels were high, especially on occlusal surfaces of deciduous molars. Approximal caries was less frequently seen and buccal and lingual sites were only slightly less frequently involved than approximal sites. Root caries was rare, even in the oldest age group. There were differences in prevalence and distribution between males and females but not between those of English and French origins. Caries levels were generally higher in those born after 1750. It is suggested that factors other than diet and oral hygiene may have influenced caries prevalence in this population.
