“…In the older age groups of our sample, caries experience was marginally higher than the 14.1 mean DMFT per person fbund by HOMAN & DAVIES (11) in 1973 for a mixed group of Aborigines c^nd Torres Strait Islanders between the ages of 35 and 44 years and considerably higher than that reported by CRAN (9) for the 30-49 and 50 and over age groups (4.0 and 9.3 mean DMFT per penson, respectively). In contrast, our results are mtich lower than the 28.5 DMFT per person found by READE (13) at and beyond 50 years of age.…”

A pilot survey of oral health included 83 adolescent and adult Aborigines (41 M, 42 F, range 16--70 years, mean age 37.3 years), resident in fringe settlements around the far western New South Wales towns of Brewarrina and Walgett (fluoride in water less than or equal to 0.02--0.26 parts/10(6)). Dental caries prevalence (mean DIMFT per person) increased from 17.1 at 20 years to 10.7 at 35 years and declined to 14.6 by the age of 50 years and over. Oral hygiene (OHI) was poor overall and deteriorated with age. Periodontal status (PI) was significantly correlated with the presence of debris (DI) and calculus (CI). The mean PI increased from 1.7 at 20 years to 4.8 at 43 years and over. Tooth mortality reached 75% by the age of 43 years. Prosthetic needs were correspondingly high, but 95% of denture requirements were unmet. No evidence of effective or sustained oral health care was seen; 38% of subjects needed emergency treatment.

“…The hypothesis that dental wear is compensated by supereruption of the dentition in order to maintain facial height has had its supporters (Begg, Sicher, 1949) and its detractors (Cran, 1957;Emslie, 1976;Tallgren, 1957; Williams, 1949). The actual mechanism by which supereruption occurs is not known, but has been discussed by Newman and Levers (1979).…”

Periodontal disease in the prehistoric Ipiutak and Tigara skeletal remains from Point Hope, Alaska

Two large groups of prehistoric Eskimo skeletons from Point Hope, Alaska, were evaluated for dental wear and several measures of periodontal disease. Occlusal attrition was found to increase steadily with increasing age. Crown height decreased proportionately. Assessing periodontal disease by inspecting apparent alveolar recession was judged ineffective due to possible supereruption. Infrabony pockets, the result of severe localized periodontal disease indicated that in Ipiutak people between the ages of 25 and 30, and Tigara people between 35 and 40, more dental sites were affected by periodontal disease than were not. This suggests a cultural, genetic, or dietary difference between the two groups. Male/female differences were slight in all parameters studied.

“…The teeth of living aboriginal Australians were studied during several expeditions of the University of Adelaide during the 1920s and 1930s (Campbell & Lewis, 1926;Campbell, 1928;Campbell & Moore, 1930;Campbell & Gray, 1936;Campbell, 1937Campbell, , 1938aCampbell, ,c,b, 1939, and 1950s (Barrett, 1953;Campbell & Barrett, 1953;Cran, 1955;Barrett, 1956;Cran, 1957Cran, , 1959Cran, , 1960, and in association with the American -Australian Scientific Expedition to Arnhem Land in 1948-1949(Moody, 1949. One of the features of these dentitions was again rapid tooth wear, associated with chipping of the enamel around the edges of the worn surfaces.…”

Dental caries is an important condition to record in archaeological collections, but the way in which recording is carried out has a large effect on the way in which the results can be interpreted. In living populations, dental caries is a disease that shows a strong relationship with age. Both the nature of carious lesions and their frequency change with successive age groups from childhood to elderly adulthood. There is also a progression in the particular teeth in the dentition which are most commonly affected and, in general, the molars and premolars are involved much more frequently than the canines and incisors. Lower teeth are usually affected more than upper, although the condition usually involves the right and left sides fairly equally. In the high tooth wear rate populations represented by many archaeological and museum collections, there is a complex relationship between the form of lesions and the state of wear, which adds yet another range of factors to the changing pattern of caries with increasing age. In the same populations, chipping, fracture and anomalous abrasion of teeth are also common, and these contribute similarly to the distribution and forms of carious lesion observed. Amongst the living, the pattern of ante-mortem tooth loss is important in understanding caries and, in archaeological material, there is also the complicating factor of post-mortem tooth loss. Finally, there is the question of diagnosis. There are diagnostic problems even in epidemiological studies of living patients and, for archaeological specimens, diagenetic change and the variable preservation of different parts of the dentition add further complications. For all these reasons, it is difficult to define any one general index of dental caries to represent the complete dentition of each individual, which would be universally suitable for studying a full range of collections from archaeological sites or museums. Variation in the nature of collections, their preservation, tooth wear, and ante-mortem and post-mortem tooth loss mean that when such a general index appears to differ between sites, there could be many other reasons for this, in addition to any genuine differences in caries incidence and pattern that might have been present. It is suggested here that the best approach is instead to make comparisons separately for each tooth type, age group, sex, lesion type and potential lesion site on the tooth.
