Paleopathology in osseous remains from the 16th century. A survey of rheumatic diseases.

OBJECTIVE: To describe the rheumatic conditions found in skeletal remains of Amerindian ancestry disinterred from a 16th century Mexican cemetery. METHODS: A physical anthropologist and 2 rheumatologists surveyed the recovered skeletal remains. RESULTS: We examined the skeletal remains of 443 subjects. We found 19 cases of Pott's disease, 17 of osteoarthrosis in various anatomical locations, 2 spondyloarthropathies, probably ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis, one probable septic arthritis in the stemoclavicular joint, and 2 compression fractures of the spine. We found no cases of gout or rheumatoid arthritis. CONCLUSION: This is the first report on the presence of rheumatic conditions in colonial Mexico. Studying the remains of these populations can provide useful information about the origin and evolution of different rheumatic conditions.

Interobserver reliability of methods for paleopathological diagnosis of dental caries.

There is disagreement as to whether clinical methods of caries diagnosis will produce reliable results in skeletal material, and studies vary greatly in the extent to which such methods are employed. The purpose of this study is, therefore, to evaluate the interobserver reliability of visual, tactile, and radiographic methods of scoring dental caries in ancient populations. Thirty-three individuals from a Mogollon skeletal sample were scored on three occasions by pairs of examiners. The first exam employed visual criteria alone. In the second exam, visual methods were supplemented with the dental explorer. For the third exam, mesial and distal surfaces were scored from "intraoral" radiographs. Examiners worked independently, but did calibrate on material from clinical populations prior to the second and third exams. Exams were conducted on a "blind" basis, and analysis was delayed until all exams were completed. Caries scores were expressed as a percentage of total surfaces present per individual. Repeat-measures ANOVA and intraclass correlation coefficients (ICC) were used to estimate interobserver reliabilities. For visual scores, ICC = 0.97, and there is no significant difference between examiners (P = 0.897). For visual plus explorer scores, ICC drops to 0.90, and there is a significant difference between examiners (P = 0.003). For the radiographs, ICC = 0.86, and there is no significant difference between observers (P = 0.117). These results suggest that clinical methods are less reliable in skeletal populations.(ABSTRACT TRUNCATED AT 250 WORDS)

Dental paleopathology and agricultural intensification in south Asia: new evidence from Bronze Age Harappa.

Patterns of dental disease among Bronze Age people of the Indus Valley Civilization are currently based on early and incomplete reports by non-specialists. This deficiency precludes accurate diachronic analysis of dental disease and its relationship with increasing agriculturalism in the Indian subcontinent. The objective of this paper is to document prevalence of dental disease at Harappa (2500-2000 B.C.), Punjab Province, Pakistan, comparatively evaluate the Harappan dental pathology profile, and use these data to assess theories regarding the dental health consequences of increasingly intensive agricultural dependence. Pathological conditions of the dentition included in the study are abscesses, ante-mortem tooth loss (AMTL), calculus, caries, hypoplasia, hypercementosis, pulp chamber exposure, and alveolar resorption. The Harappan dentition exhibits a dental pathology profile typical of a population whose subsistence base is agriculture. Dental caries at Harappa are present in 6.8% (n = 751) of the teeth and 43.6% (n = 39) of the more completely preserved dental specimens. The use of a caries correction factor is recommended to permit an estimate of caries induced AMTL in calculating the caries prevalence. All dental lesions are present at higher rates in this Harappan study sample than were reported in previous investigations, and important differences in prevalence of dental disease occur between the genders. Prevalence of dental disease increases in the greater Indus Valley as subsistence becomes more intensive and as food preparation and storage technology becomes more efficient.

Dental paleopathology in a Serbian Medieval population.

Analysis of the pattern of dental disease in two Late Medieval populations from cemeteries excavated at archaeological sites in western Serbia was based on the study of tooth wear, ante-mortem tooth loss, caries, dental enamel hypoplasia, alveolar resorption, abscesses and calculus. The findings reported here show a high prevalence of attrition, alveolar resorption and caries, which suggest an abrasive diet and poor oral hygiene.

Dental studies of a Finnish skeletal material: a paleopathologic approach.

This paper reviews a series of paleo-pathologic studies made to investigate associations between dietary factors and development of occlusion, periodontal diseases and caries. The findings indicate that the change from hard to soft food, which has taken place during the last few hundred years, influences occlusion, craniofacial structures and oral health in several ways. Comparative studies show that the frequency of malocclusion has increased substantially. In the same time, a number of alterations have taken place in the morphology of the craniofacial skeleton. The results support the hypothesis that masticatory stress is a regulative factor in craniofacial growth and occlusal development. With soft food and low masticatory activity, jaw growth is not adequate for optimal occlusal development. Approximal wear itself, caused by the attritive diet, seems to be only a minor adjustive factor. Because of the occlusal wear, the crown height decreased with age and the teeth continued to erupt. As a result, root surfaces were exposed. This process has been equated with bone loss but the lack of inflammatory changes on the bone surface indicates that the alveolar bone was not affected by periodontal diseases. This suggests that the alveolar height was maintained at a constant level throughout life and no growth nor resorption took normally place at the crest. Only the exposure of the furcations increased the occurrence of periodontitis. The caries frequency was decreased by mechanical cleaning effect of attritive food but increased by exposure of the root surfaces. Furthermore, the oral microflora may have been modified by factors related to the chemical and physical properties of the diet.
