The objective of this work is to evaluate temporal variation of dento‐alveolar lesions in hunter‐gatherer groups who inhabited the middle course of the Negro River during the late Holocene (ca. 3000‐750 years BP) in order to discuss cultural practices and changes in the paleodiet. Caries, dental calculus, periodontal disease, periapical lesions, antemortem tooth loss, tooth wear, dislocation, and osteoarthrosic lesions in the temporomandibular joint were analysed. The sample is represented by 567 teeth and 547 alveoli, corresponding to 32 adult and subadult individuals, who were divided into two periods for comparative purposes: pre‐1000 and post‐1000 BP. The results indicate a low prevalence of oral lesions without differences between sex and age. In the pre‐1000 BP period, there is a larger frequency of antemortem tooth loss, parafunctional wear of the anterior teeth, dental dislocations, and osteoarthrosis in the mandibular condyles compared with the post‐1000 period. This tendency indicates that the individuals would have been exposed to greater stress in chewing. However, the variations were not significant, so there is no clear evidence of changes in the diet and particularly in carbohydrate and plant intake through the late Holocene. Severe tooth wear is the main factor that caused some pathologies (e.g., antemortem tooth loss), and limited the development of others (e.g., caries). The results obtained here agree with other microregions from northeastern Patagonia and differ from Humid Pampas, eastern Pampa‐Patagonian transition, and lower course of the Negro River due to differences in carbohydrate consumption in the last ca. 1000 years BP.  相似文献

The current project is a study of craniofacial trauma in a large sample (n = 896) of Prehispanic Canary Islanders (PCIs). The possible causes and social implications of the trauma found are considered, with reference to archaeological and historical data. Variables include the island, period and ecology, the sex and age of the individuals, the distribution of lesions across the skull (by side and by individual bone) and ante‐mortem tooth loss. The results show a fairly high trauma rate (16%), a low prevalence of peri‐mortem trauma (3.8% of all lesions), higher prevalence of trauma in males than in females (25% vs. 13% of all individuals), more cranial than facial lesions (8.9% vs. 3.5% of all elements) and more lesions on the left side of the skull (6.7% vs. 4.5% of all elements) which suggests that the lesions were sustained through intentional rather than accidental agency. There was no correspondence between trauma prevalence and ecology. The archaeological and historical data support the assertion that the lesions may be the result of skirmishing between groups, using weapons such as slingshots, stones and staves. The presence of edged‐weapon lesions on some individuals suggests that these may have been the victims of contact‐period European groups. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Differences in dental health of prehistoric human groups are commonly attributed to specific subsistence practices, whereby food foragers generally have a lower incidence of dental disease than agriculturalists. Dental health was assessed on a sample of 135 human skeletons from northwest Mexico that date to the Early Agricultural period (1600 BC–AD 200), which coincides with the initial introduction of domesticated cultigens into the region c. 2000 BC. High rates of dental caries (13.5%) and antemortem tooth loss (17.6%) encountered in these prehistoric forager‐farmers from the Sonoran Desert were determined to be the result of the consumption of highly cariogenic local wild resources such as cactus. These patterns mask the degree of reliance on agriculture in the area and highlight the importance of constructing local nutritional histories to better understand the diversity of human diets and their relationships to health and disease.

This study examines evidence for dental disease (caries, abscesses, antemortem tooth loss and severity of dental wear) in Nubian and Egyptian groups living in the Nile Valley during the New Kingdom. Specific attention is given to individuals buried at the site of Tombos, a cemetery in Nubia used during the Egyptian colonial occupation. In addition, three Nubian and two Egyptian samples are included for comparative purposes. While some similarities in condition frequencies between Tombos and the comparative groups are apparent, especially in the rates of caries and abscesses, significant differences in antemortem tooth loss and severity of tooth wear point to variation in these Nile Valley samples. These differences are especially evident for males. Higher rates of these conditions at Tombos may be attributed to the socio‐political and cultural changes taking place during this time of colonial occupation. Changes in foodways and occupational environments may have resulted in stress, as demonstrated by these dental conditions experienced by the Tombos people throughout this transitional period.

Studies on the mobility of past populations are useful in the interpretation of trade and lifestyle. Preservation of ancient paths is uncommon. In Tenerife, a volcanic island of the Canary Archipelago, ancient paths are still preserved, due to the dry climatic conditions and the presence of extensive lava fields in inhospitable areas of the Island. The Guanches who inhabited this island before the Spanish conquest, those surviving in the highlands after the conquest, and modern goatherders, utilised a still identifiable net of paths to access the central mountains. Clasts in the beds of these paths have suffered variable abrasion, depending on the time during which the path was used and on the number of people and/or animals that have walked on it. We estimated roundness of 1819 clasts collected at different parts of the net of paths crossing different lava fields of known antiquity. Significant differences in roundness of clasts among different parts of the paths allowed an inference about the relative importance of each of the paths constituting the net. Therefore, assessment of roundness of the clasts of the beds of paths may aid in the understanding of the migrations of people.  相似文献

Nitrogen and carbon isotope compositions were measured in the bone collagen from a total of 86 prehispanic samples of the Canary Islands, and hydrogen in 70, all of them with enough amount of bone collagen, and adequate N and C content. These samples belong to prehistoric population of El Hierro (n = 27), Tenerife (n = 18), and Gran Canaria (n = 41). Isotope compositions were also obtained for prehistoric and modern food resources that were likely consumed by these people. Marked differences were observed among the three islands regarding the three isotopes analyzed: the δ15N values were highest among the population of Gran Canaria (10.8‰ ± 0.9‰), who also showed the highest δD values (7 ± 8‰). The population of El Hierro showed the highest δ13C values (−18.6‰ ± 0.7‰). These data suggest a high consumption of marine products by the population from El Hierro, and also an important consumption of terrestrial meat or marine, piscivore fish, by the population from Gran Canaria, together with domesticated C3 plants (barley and/or wheat), fruits of Ficus carica and other wild species, and goat products. Additionally, marked differences were observed between men and women, which suggest that women consumed a more vegetal-based diet, a finding which is in agreement with the higher proportion of teeth with carious lesions among women.  相似文献

Perimortem traumas have been identified in a pre‐Hispanic Canary mummy (fifth–sixth centuries cal AD). The location and nature of the fractures in the cranium, cervical vertebrae, ribs and both legs indicate a fall from a considerable height, which would have been the cause of death. Supported by forensic anthropology criteria and historical information about the population of origin, the circumstances in which the fatal injuries might have occurred are discussed. Given the pattern of the injuries, it is debated whether they were the result of an accident or a ritual suicide, as aggression is thought to be a less likely scenario.

European expansion in the Atlantic in the Late Middle Ages often implied the use of violence, involving tactics and weaponry unknown to some of the affected populations. Among the first places to suffer this violence were the Canary Islands, whose conquest lasted the whole of the 15th century. Documentary information about this historical episode is abundant, whereas archaeological evidence testifying to it is very rare. However, an individual from an indigenous funerary context of Gran Canaria (placed in a collective burial cave and wrapped in a shroud made of vegetable fibres) displays a large number of wounds, both on his skull and on the rest of the skeleton, probably caused by swords, suggesting a mortal attack conducted by one or more aggressors. Based on the study of injuries, it is considered a potential explanation of their origin, concluding that most likely this case may be associated with the process of the conquest of the Island.

While posterior lingual mandibular depressions (Stafne's defect) are often discussed in clinical reports, they are rarely the subject of anthropological research. This situation is paradoxical since osteologists and skeletal biologists are in a position to enhance understanding of the trait's aetiology by systematically recording the trait in recent and prehistoric skeletal collections. This report reviews anthropological studies of cortical defects of the mandible, recommends a protocol for recording observations in trait variation, and presents new data for the prevalence of Stafne's defect—lingual cortical defects of the mandibular corpus. Among the Guanches of Tenerife in the Canary Islands (Spain), the prevalence of lingual cortical defects is 3.32% (15/452), males are more frequently affected than females, and there is a tendency for individuals with antemortem tooth loss to display larger lesions than individuals without antemortem loss of teeth. Defects of the left side are somewhat more variable in position than defects located on the right. In comparative perspective, prevalence of lingual cortical defects among the Guanches is high, given the overall 1.07% prevalence reported for archaeological series (Finnegan & Marcsik,1980), but is similar to figures reported for the Avar period sample from Hungary 3.73%. Prospects for the use of lingual cortical defects as non‐metric traits of value in population distance studies remain uncertain since variation in trait expression may have a high environmental component. However, if human osteologists routinely include observations of lingual mandibular cortical defects in their analysis of skeletal collections, the data required to elucidate factors responsible for the trait's cultural, ecological, temporal and geographical patterning will more rapidly become established.

An archaeological case of clay‐shoveler's fracture was observed in an adult male exhumed from a Roman necropolis dated to the 1st–3rd century AD and located in the city of Barcelona, Spain. Clay‐shoveler's fracture is a breakage of a lower cervical or upper thoracic spinous process as a result of mechanical stress. Different mechanisms have been related to this injury, generally in labour‐related contexts. This paper reviews the literature concerning this uncommon finding, focusing especially on its mechanism and on activity‐related lesions. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Dento‐alveolar pathologies: caries, ante mortem tooth loss, abscesses, calculus, alveolar resorption and tooth wear were analysed in two composite skeletal series from Croatia's eastern Adriatic coast (Dalmatia). The first consists of 103 skeletons from seven Late Antique (3rd–6th century AD) sites, the second of 151 skeletons from three Early Medieval (7th–11th centuries AD) sites. As recent bioarhaeological studies (Šlaus, 2008 ) showed a significant increase of disease loads and trauma frequencies in Dalmatia during the Early Medieval period, the aim of this study was to investigate whether dental health was equally adversely affected by the Late Antique/Early Medieval transition. The results of our analyses show that the frequencies of carious lesions, ante mortem tooth loss, abscesses and alveolar resorption increased significantly during the Early Medieval period, as did the degree of heavy occlusal wear on posterior teeth. These data suggest a change in alimentary habits, with a significantly higher dependence on carbohydrates and a greater reliance on hard, fibrous foods requiring vigorous mastication in the Early Medieval diet. The combination of higher calculus and lower caries rates in the Late Antique series similarly suggests more protein in the Late Antique diet and is, therefore, also consistent with the hypothesised change in alimentary habits. In general (the two exceptions are male caries and female alveolar resorption frequencies) lesion frequencies increased uniformly in both sexes suggesting that the deterioration of dental health during the Early Medieval period equally affected males and females. Cumulatively, the collected data suggest that the political, social, economic and religious changes that characterised the Late Antique/Early Medieval transition in Dalmatia resulted in a clear discontinuity, not only from the cultural, but also from the biological point of view with an evident deterioration of oral health during the Early Medieval period.

The analysis of dental remains, which outlast most other tissues in the human body, provides insight into past diet, activity patterns and ancestry. The remains from Bab edh‐Dhra' represent the only skeletal sample available to assess the impact of agricultural intensification in the Early Bronze Age of the southern Levant (ca. 3500–2000 bce ). This era ushered in a period of ‘urbanisation’, evidenced by fortified towns, planned roadways, developments in irrigation and growing population density. During this time, the cultivation, trade and consumption of orchard taxa (such as figs, grapes and olives) increased. This paper examines changes in the teeth associated with agricultural intensification involving orchard crops as well as grains. Dental caries, ante mortem tooth loss and dental wear are examined for Early Bronze IA (EBIA; 3500–3300 bce ) and Early Bronze II–III (EBII–III; 3100–2300 bce ) teeth from the site of Bab edh‐Dhra', located in modern‐day Jordan. Due to the commingling, general tooth groups (e.g. molars) and specific tooth types (e.g. lower left canine) were used to compare periods. Although age and sex could not be identified for every tooth, analyses of crania and os coxae showed no significant difference in demographic profiles of EBIA and EBII–III. No statistically significant increase was found over time in dental caries frequency; however, teeth for which the cause of pulp exposure could be determined suggested that caries increasingly led to exfoliation. Indeed, ante mortem tooth loss rose significantly with time, whereas dental wear decreased. In general, changes in oral health were consistent with an archaeological record of greater consumption of softer, stickier foods, such as fruits. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
