A method of assessing periodontal status in archaeologically derived skeletal material

A method is described for estimating periodontal health in archaeologically derived human dentitions. The basis of the method is the classification of the architectural from and textural appearance of interdental alveolar bone. Five distinct categories of surface and texture were observed in a series of Late Mediaeval Scottish skulls. Macroscopic and microscopic examination demonstrated these categories were also recognisable in modern clinically diagnosed phases of periodontal disease. The method is in accord with present day concepts of the pathogenesis of periodontal disease, overcomes problems associated with post-mortem tooth loss and those of linear measurements of root exposure. It provides a basis for epidemiological studies of past populations.
