Cutting the cake: the Congress of Vienna in British,French and German political caricature

Although the Congress of Vienna was not a main topic for political caricature, it was anything but ignored. During the first five months of 1815, while monarchs and diplomats were deliberating on Europe’s future, caricaturists in Great Britain, France and the German-speaking states depicted the Congress as a major or minor subject in 20 satirical prints. Together these caricatures provide a multi-perspectival view of the way contemporaries assessed the diplomatic deliberations taking place in Vienna. To obtain an insight into this important part of contemporary public opinion on the Congress, the corpus of graphic satire was submitted to close scrutiny in two ways. Firstly, a context analysis ascertained the artists who produced them; how the prints were published and brought to public attention; and for what audiences they were intended. Secondly, a content analysis explored the political messages that the caricatures on the Vienna Congress tried to convey and the persuasive techniques that were applied to visualise these points of view. Notwithstanding different national origins and opposite political views, the message is a negative one: the satires denounce the territorial greed of the Great Powers and their disregard for the demands and aspirations of the peoples they seek to incorporate.     

Starch granules,dental calculus and new perspectives on ancient diet

Recent work in various parts of the world has suggested the possibility of ancient starch granules surviving and adhering to archaeological artefacts. Often this information is used to infer aspects of diet. One additional source for recovery of archaeological starch granules is dental calculus. The presence of plant food debris in dental calculus is well known but has not been not widely investigated using archaeological material. The extraction of starch granules from dental calculus represents a direct link to the consumption of starchy food by humans or animals. Using dental calculus also sidesteps many other questions still inherent in using starch granules to reconstruct aspects of ancient diet, such as the effects of diagenesis on their morphology; as the starches are trapped inside a concreted matrix they are less likely to alter over time. We used amylase digestion by a starch-specific enzyme to confirm the material as starch.     

The dental arcade and human morphology

Cranio-dental fossils are relatively common in the fossil record and this paper considers the question of whether the dental arcade can act as a predictor of hominid morphology. A method of measuring the catenary number of an arcade is also described and defined. © 1998 John Wiley & Sons, Ltd.     

Diet and the aetiology of dental calculus

The aetiology of dental calculus formation is not fully understood, but it is known that a number of factors play a role. Generally, anthropologists have overlooked the role of other causative factors in the formation of dental calculus, attributing it almost exclusively to diet, particularly protein consumption. Anthropologists have also oversimplified the role of diet in the formation of dental calculus. This may be due to a general paucity on research on dietary effects on calculus formation, as well as a lack of integration between anthropological and non‐anthropological data.

The frequency and distribution of dental caries and tooth wear in a Byzantine population of Sa'ad,Jordan

The aim of this study was to determine the frequency, distribution and extent of dental caries and tooth wear in a Byzantine population in Sa'ad, to compare these with modern Jordanians, and to draw inferences about their lifestyle. Dental caries and tooth wear were examined in 1159 permanent teeth using direct vision and dental explorer. The location and extent of the lesions were recorded and evaluated according to defined criteria. The overall caries prevalence was 16.8% (n = 1159). Most of the carious lesions (13. 9%, n = 1159) were present in the tooth crown, on occlusal or proximal surfaces; 2.9% of teeth displayed root caries alone. The upper and lower central incisors exhibited the lowest coronal caries frequency, while molars showed the highest frequency. Attrition with moderate dentine exposure was evident in most teeth. Some teeth (9.8%) demonstrated oblique abrasion and 9 (0.78%) teeth exhibited cupped occlusal surfaces. The prevalence of caries was within the range reported for other Byzantine populations and lower than that of modern Jordanians. The attrition seen in most teeth and the cupped occlusal surfaces might be due to eating abrasive food, drinking wine or acidic beverages. Oblique abrasion on the facial and palatal surfaces reflects their business or craft, such as basket making and leather processing. Copyright © 2008 John Wiley & Sons, Ltd.     

Exceptional rates of dental caries in a scandinavian Early Iron Age population—A study of dental pathology at Alvastra, Östergötland,Sweden

The dental status of Early Iron Age agricultural populations in Sweden has not been extensively documented. The aim of this study was to record caries status in human remains from an Early Iron Age burial ground, Smörkullen, at Alvastra, Östergötland, Sweden. The study included 96 adults and 50 subadults and comprised 1794 permanent teeth in the adults and 468 permanent and 221 deciduous teeth in the subadults. The caries frequency was exceptionally high, afflicting most of the adults (92.6%): 46.2% of the teeth examined showed signs of caries disease. Most of the lesions were shallow. However, around 60% of the adult individuals had moderate and severe lesions, which probably had an immediate impact on health. Lesions were most common in the cervical region and this is probably related to dietary patterns where the starchy, sticky food tended to accumulate around the necks of the teeth. Children showed low caries frequency, whereas most juveniles (91.7%) were affected. Most of the teeth with alveolar bone loss showed no signs of cervical or root caries lesions. However, in cases of moderate and severe loss of alveolar bone, seen mostly in the older age group, the frequency of cervical and root lesions was higher. Few initial caries lesions were observed, indicating an aggressive pattern of disease in this population. The lack of gender‐related differences suggests that the diet was similar for both sexes, across all age groups. Copyright © 2010 John Wiley & Sons, Ltd.     

Identification of historical human skeletal remains: a case study using skeletal and dental age,history and DNA

Excavation of an early historical (circa 1900) church cemetery in Cochrane, Alberta, Canada, revealed the graves of six individuals. All but one had been previously excavated and the individuals were re‐interred elsewhere. The remaining grave contained a coffin burial of an infant including most of the skeleton, crowns of forming deciduous teeth, scalp and hair. The remains were excavated and historical research was carried out to determine possible families who had used the cemetery. Skeletal and dental age estimates pointed to a particular individual described in historical records. This identification was confirmed through more precise ageing by dental microstructure, sex determination using DNA, and finally, maternal relatedness by comparison of mtDNA with a living female relative. In addition to describing the analytical methods used, this paper demonstrates the importance of accurately identifying historical burials, particularly when living relatives remain in the community.

Dental calculus and other dental disease in a human skeleton of the Okhotsk Culture unearthed at Hamanaka-2 site,Rebun-Island,Hokkaido, Japan

A human skeleton of the Okhotsk Culture from the Hamanaka-2 site of Rebun Island, northern part of Hokkaido, was found with abnormally large deposits of dental calculus, especially on the right upper 2nd and 3rd molars. This may relate to the early loss of the corresponding right lower molars. Root apex cementum hyperplasia and resorption of alveolar bone due to periodontal disease were also observed; these may have been associated with the calculus. The severe dental calculus and other diseases observed appear to have nothing to do with the subsistence pattern and ethnological background of the Okhotsk Culture, but rather with the individual's poor oral hygiene and digestive dysfunction.     

Correlation between dental occlusal wear and approximal facet length

The aim of this paper is to examine the relationship between occlusal surface wear and approximal facet length in a North American archaeological sample of modern human hunter–gatherers (n = 111) and agriculturalists (n = 123). First maxillary molars (M¹) were selected. The approximal wear facet was measured on the mesial surface of each M¹ at the widest breadth using needle tipped digital callipers. Digital images were taken of the occlusal surface and wear was recorded as the percentage of dentine exposed to the total occlusal surface. Independent age estimate was based on age‐related changes, (pubic symphysis and auricular surface). Results show the hunter–gatherers had a significantly faster rate of wear on both tooth surfaces compared to the agriculturalists in each of the four age groups. Both lifeway groups showed a positive correlation between the two tooth surfaces during the early stages of tooth wear (less than 25% occlusal wear), where the percentage of occlusal wear and the length of the approximal facet increased at a similar rate. During the middle and final stages of tooth wear (occlusal wear greater than 35%) there was a strong negative correlation between the two surfaces in both groups. It is suggested this pattern is due to the shape and function of the M¹. Both correlations were more extreme in the hunter–gatherers than the agriculturalists. When the per cent of occlusal wear exceeded 35% the length of the approximal facet started to decrease, and it is therefore recommended studies that include approximal wear exclude molars with heavy occlusal wear.

Periapical lesions and dental wear in the early Maori

Dental wear and intrabony lesions were evaluated in a sample of 225 skulls (136 male) of pre‐contact New Zealand Maoris. The degree and direction of surface wear was scored according to the method of Molnar ( Molnar 1971 . Human tooth wear, tooth function and cultural variability. American Journal of Physical Anthropology34: 175–190) and revealed severe surface loss in both males and females with horizontal wear being the dominant pattern (62.4% male, 57.5% female). The width of coronal tissue above the pulp chamber, as well as the maximum depth and width of periapical lesions, was measured from both standard radiographs and digital images. The high prevalence of periapical pathology in the Maori underlined the extreme nature of dental wear in these people. It is postulated that this degree of tooth loss may be attributable to a change in diet from large birds to marine‐dependence, the introduction of the kumara to New Zealand, dental erosion and finally, to the excessive masticatory forces exerted by a robust facial complex on normally sized teeth. Fenestrated lesions were highly prevalent (83% of skulls) and were centered mostly on the maxilla, with an even distribution among tooth classes. The finding of periapical lesions in teeth with minimal observable wear was attributed to traumatic occlusion. Copyright © 2001 John Wiley & Sons, Ltd.     

Dirty teeth and ancient trade: Evidence of cotton fibres in human dental calculus from Late Woodland,Ohio

Analysis of ancient human dental calculus for the presence of inclusions related to diet and dental health has been overlooked in anthropological literature. Small particles of archaeobotanical debris, which would otherwise not be preserved in the archaeological record, can become incorporated into unmineralised plaque on teeth during mastication and oral manipulation. When plaque mineralises into calculus, debris is preserved in situ. Samples of dental calculus (n = 18) were collected from the Danbury site (33OT16) in Ottawa County, Ohio and viewed under a scanning electron microscope for inclusions. Analysis yielded a variety of noticeable inclusions, including mineralised bacteria, calcium‐phosphate crystalline structures and numerous phytoliths. Here we report the first evidence of fibres consistent with cotton (Gossypium spp.) embedded in the dental calculus from the Late Woodland component (900–1100 AD ) of the Danbury site. Prehistoric cotton has not been previously documented in Ohio. The distinct morphology of the Danbury cotton and its presence in the Late Woodland component at Danbury suggests long‐distance interaction at a time in Ohio when movement of exotic goods appeared to have diminished. These microscopic remains provide insight into paleoethnobotanical history of ancient Ohioans and attest to how analysis of dental calculus could be used to supplement other paleodietary and archaeological analyses.

Palaeopathology in late Pleistocene and early Holocene Central Plains bison: dental enamel hypoplasia,fluoride toxicosis and the archaeological record

Multiple formative agents are cited for dental enamel hypoplasia (DEH) in modern and fossil mammals. Here, four late Pleistocene-early Holocene bison assemblages from the Central Great Plains are analyzed for DEH and other bone pathologies to investigate the possible influence of chronic fluoride toxicosis, a condition that may have presented a long-term source of duress for prehistoric bison and devalued them as nutritional resources to human hunters. Although DEH is present in all the analyzed assemblages, the lack of corroborating dental and post-cranial anomalies consistent with chronic fluoride toxicosis speaks against it as a primary factor of DEH formation or general ill health in these bison. Rather, maternal nutritional stress, weaning, and seasonal forage condition are invoked as probable promoters of DEH formation. Other identified abnormalities are discussed in reference to their contribution to reduced feeding efficiency and lameness, as are their roles in developing palaeoecological models applicable to archaeological questions about ancient human lifeways.     

Nonmetric dental characteristics of the early modern population of Okinawa Island in Nansei Islands,Japan

Dental morphological characteristics of the early modern population (c. 17–19th century AD) of Okinawa Island, Nansei Islands, were investigated to clarify their genealogical characteristics. We observed and classified 25 nonmetric traits of tooth crowns and roots from human remains (106 individuals) excavated from tombs of the early modern period in Okuma, Ginowan City, Okinawa. The incidences of these traits were compared with the incidences in the populations of the other Nansei Islands, of Japan, and of Asia overall. Univariate analysis of each trait and multivariate biological distance analysis based on the frequencies of the traits showed that the Okinawa population in the early modern period more closely resembled the migrant Yayoi populations than it did the native Jomon populations. It is difficult to support the “Ainu‐Ryukyu common origin theory” with regard to the early modern population in Okinawa without some modification of the theory, as well as the modern populations in Tanegashima and Okinawa Island. The geographical cline in the modern period from the northern Kyushu to the Okinawa Island via Tanegashima was confirmed in this analysis. Considering the major temporal changes in northern Kyushu and Tanegashima in addition to the geographical cline, the southward gene flow of the migrant Yayoi elements from northern Kyushu to the central Nansei Islands via the northeast end of the Nansei Islands is suggested. In addition, this study detected some temporal changes from the early modern to the modern period in Okinawa Island. Although the minor temporal change may be attributed to some genetic drift, gene flow from the Japanese main islands or China might be considered one of the causes of the change.
