The levels of tooth wear were surveyed in 50 pre‐contact Maori skulls (23 of them female) from New Zealand. In addition to a generalized tooth wear index, we evaluated occlusal wear for erosion and abrasion. Occlusal microwear was also investigated using scanning electron microscopy (SEM) images and, finally, the occlusal slope was determined at the level of the first molar teeth. The general pattern of wear was one of severe occlusal reduction with no significant differences between males and females. Both silicone impressions and SEM views confirmed a large component (30%) of erosion. While most individuals had flat wear planes, 33% of males and 44% of females showed reversed Monson's curves. Accentuated Monson's curves were found in 23.8% of males. While these results confirm early studies of the excessive wear experienced by pre‐contact Maori, our study shows for the first time that erosion played a significant role in the dental wear of these people.

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.

Periapical lesions can develop after exposure of a tooth's pulp chamber and are commonly associated with heavy crown wear, trauma, or caries. In this study, maxilla and mandible fragments from the South African fossil hominin collections were studied, including specimens assigned to Homo naledi, Paranthropus robustus, Australopithecus africanus, and early Homo. Gorilla gorilla gorilla, Pan troglodytes, and Homo sapiens were also studied for comparative purposes. Only one fossil hominin specimen displayed voids consistent with periapical lesions. The specimen, SK 847, is described as early Homo and has been dated to 2.3–1.65 Ma. There is one definite periapical lesion and likely more with post‐mortem damage, all on the anterior aspect of the maxilla and associated with the incisors. The lesions originate from the apices of the incisor roots and are therefore unlikely to represent a systemic disease such as multiple myeloma. The one well‐preserved lesion was likely an abscess rather than a cyst or granuloma, with a rounded thickened rim around the lesion. These lesions in an early Homo specimen highlight that this individual used their anterior dentition extensively, to the point that the pulp chambers were exposed on multiple teeth. This is one of the earliest hominin examples of periapical lesions and shows that this individual was able to cope with potentially several concurrent abscesses, clearly surviving for an extended period. Periapical lesions are relatively common in the great ape (P. troglodytes: 1.99%; G. gorilla gorilla: 1.86%) and human samples (2.50%) but absent in large samples of P. robustus and A. africanus (n = 0/373 teeth). Therefore, this finding adds additional information to the history of dental pathology in our genus and also suggests that other hominin genera may have been less susceptible to dental abscesses, potentially relating to dietary or behavioural differences.  相似文献

This paper provides an investigation of pulp stones in a sample drawn from the historical population of Radom, Poland, dating to between ad 1791 and 1811. This study seeks to determine the frequency of pulp stones, and assess the association between pulp stones and sex, age, dental caries, and dental wear. A total of 780 teeth from 121 adult individuals of both sexes (45 females, 76 males) were examined. Analysis was limited to molars. The average age‐at‐death of each individual was estimated. Total wear scores across the molars were calculated for each individual. Pulp stones were identified by a portable dental X‐ray machine. Pulp stones were found in 94 of 121 individuals and in 273 of 780 molars. No statistically significant correlation was found between pulp stones and age‐at‐death (p  = 0.7625) and sex (p  = 0.0915), but a significant relationship was found between pulp stones and dental wear (p  < 0.0001) and dental caries (p  = 0.0016). Our study found that molars affected by highly advanced dental wear were significantly more often accompanied by pulp stones than molars that had experienced limited wear. Similarly, significant correlations were observed for dental caries. It means that pulp stone formation appears to have been contingent upon the irritation of the tooth crown by factors such as forces acting on the tooth crown leading to dental wear or dental caries.

Using morphological and radiographic methods, we analysed the dentitions of 24 individuals from Ingombe Ilede and Isamu Pati Zambian Iron Age archaeological sites. In this study, we determined the frequency and distribution of attrition, pathological conditions and dental trauma. This research also presents the first view of dental health for an Iron Age population in southern Africa. In total, 482 teeth were available for this study with 287 teeth missing, where 50 of these were lost antemortem and one individual had an erupted supernumerary first mandibular incisor. With the use of radiography and morphology, 21.5% (104/482) of the analysed teeth had at least one pathological condition or evidence of dental trauma. Some interesting dental aspects found and discussed in this paper are linear enamel hypoplastic lesions, radicular resorption, periapical lesions, fractures, dental modification and carious lesions. Many of these features were diagnosed with radiography, and this was especially important for those found below the cemento‐enamel junction (p = 0.0202) that are less obvious with macroscopic investigation alone. Additionally, the quantity and direction of dental attrition was studied. There were observed sex differences with the direction of wear, likely representing a sex‐specific cultural practice of using teeth as tools. Overall, the results show that this sample suffered relatively little from dental problems, and many of those observed features were associated with the traumatic procedure of dental modification, whereas others were age and diet‐related. Additionally, with the use of radiography, rare dental fractures and other features were diagnosed; these results demonstrate the requirement for its application in dental studies on archaeological assemblages.

This study investigates temporal changes in dietary practices in the Caribbean archipelago during the Ceramic Age (400 BC–AD 1500), through analyses of dental wear and pathology. Some previous studies in the region have suggested that diet and subsistence practices changed over time due to increasing sociopolitical complexity, climate change, or adaptation to island environments rich in marine resources. Both horticultural/agricultural intensification and increased marine focus of the diet over time have been posited, based among other things on faunal and botanical remains, and early ethnohistorical accounts. Local and micro‐regional stable isotope studies of temporal dietary variation have found few indications for change over time, and large regional isotope studies are still lacking. Dentitions from sites throughout the region dating to the Early Ceramic Age (400 BC–AD 600/800) and the Late Ceramic Age (AD 600/800–1500) were analysed in order to assess temporal differences. Intra‐individual rates of wear were calculated using the difference in degree of wear between the adjacent molars and the two groups were compared with principal axis analysis. Caries, antemortem tooth loss, abscesses and dental calculus were recorded per individual and per tooth/socket, and population caries and antemortem tooth loss rates were assessed and compared by age group, tooth class and sex. Comparisons between the two occupation periods revealed significant differences in the rate of dental wear and pathology, indicating a shift in dietary practices over time, coinciding with known social changes. The increase in pathology rates suggests a rise in the consumption of cariogenic foods or preparation techniques that increase cariogenicity. The decrease in rate of wear over time indicates a reduction in abrasivity of the diet. Together these data suggest that there was a growing focus on refined, cariogenic foods, likely horticultural/agricultural produce. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

The present study will focus on the analysis of pulp stones and dental wear of an adult (26–30 years old) individual from Woźna Wieś, dated from the Mesolithic period (5900 ± 100 BC ). The dental material included 14 permanent teeth. Cone beam computed tomography was used in the identification of pulp stones. Pulp stones were classified by location and volume. The scores for mechanical dental wear were based on the scales proposed by Smith and Scott. The anterior teeth showed an advanced stage of mechanical dental wear. The first molars exhibit higher wear scores than the second and third molars. The pulp stones were diagnosed in 10 teeth (10/14, 71%). Generally, these calcified structures were found in the pulp chamber (10/14, 71%). The relationship between the stages of dental wear and the presence of pulp stones turned out to be statistically significant (p = .012). The correlation coefficients between tooth wear and pulp stones in the pulp chambers and root canals were .434 and .327, respectively. The pulp stones occur most frequently on the teeth with advanced dental wear. However, we also cannot rule out the dietary factor. It can be supposed that this individual's diet did not lack products with high calcium content.  相似文献

Intentional dental modifications are alterations of teeth usually performed as a ritual for aesthetic or identity purposes. However, the execution of the technique is not exempt from risk and can be related to a higher prevalence of dental pathology, more specifically through the exposure of the dental pulp and consequent periapical inflammation. With the aim of analysing the relationship between intentional dental modifications and periapical inflammation, the current study evaluated 81 skeletons (49 women, 19 men, and 13 individuals of unknown sex) of enslaved Africans from Lagos, Portugal (15th–17th centuries), of which 50 (61.7%) had intentionally modified teeth. In all, 2285 sockets and 2063 teeth were observed. Two hundred and three intentionally modified anterior teeth (27.2%) were identified. Twenty five individuals (30.9%) and 54 teeth (25 anterior and 29 posterior) showed macroscopic evidences of periapical lesions. In the anterior dentition, intentional modification was identified as the probable aetiology of 17 (68.0%) periapical lesions, mostly granulomata or cysts, but also abscesses. The association between intentional modifications of the dentition and the presence of periapical lesions was found in both the maxilla and mandible. These results suggest that this cultural practice can predispose teeth to periapical inflammation, which may cause pain and sensitivity to cold, heat, and pressure, and probably had a negative impact on the quality of life of these individuals.

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 patency of the premaxillary suture in adult humans remains controversial. Here we report on the extent and shape of the suture in 51 precontact New Zealand Maori adults (21 males, 30 females). When data were combined for both sides and also for full or more than half patency, males showed a prevalence of 44.2% and females of 33.5%. Females were found to have significantly more sinusoidal rather than V‐shaped forms. We hypothesize that the retention of the premaxillary suture into adulthood may be a neotenic feature which has allowed the Maori to achieve their uniquely large phenotype.

Dental examination of 21 individuals (11 females, nine males and one undetermined sex) exhumed from the rock‐cut tombs of Torre Velha 3 (Serpa, Portugal), dating from the 2nd millennium BC, revealed dental wear features and oral lesions that can be linked to non‐masticatory activities and/or dietary habits. A total of 471 teeth were macroscopically analyzed. One young‐adult female and a middle‐age adult of unknown sex display lingual surface attrition of the maxillary anterior teeth (LSAMAT). A middle‐age adult female has LSAMAT, anterior occlusal surface groove (AOSG) and chipping. Two other middle‐age adult females have oblique wear planes (OWP), one of them also with chipping. Overall variation and low frequencies of the observed alterations suggest that multiple activities and/or dietary habits could have caused these wear patterns. The hypothesis that atypical wear patterns are sex biased was tested using Fischer's exact test, and results were not statistically significant (p‐value = 0.09). Thus, it is possible to infer that these individuals had possible dietary or cultural idiosyncratic behaviors, besides repetitive non‐masticatory task related‐activities.  相似文献

ABSTRACT Whanganui National Park is one of New Zealand's leading tourist attractions. Tieke Kainga (Tieke settlement) is a Department of Conservation camp site in the middle reaches of the river that was occupied in the mid‐1990s by members of Tamahaki an indigenous group who claim that the land was taken from them illegally. Although a modus vivendi currently exists whereby the Department and Maori group co manage the site, Tamahaki's struggle for exclusive ownership of it continues. Part of the strategy they adopted to solidify their claim involves welcoming tourists and government officials to Tieke Kāinga in a manner that accords with Maori tradition. Such welcomes establish dramatically that Tamahaki own Tieke and that the guests formally acknowledge by their participation in the performance that they are visitors. This paper questions the authenticity of the welcomes performed there and concludes that they are real for good reason. Authentic Maori welcomes solidify Tamahaki's occupation of Tieke and broadcast the morality of their claim to the site.  相似文献

The main aim of this study is to present a novel method of nonadult (ca. 1–19 years) age‐at‐death estimation using the dental wear of deciduous, mixed deciduous‐permanent, and permanent dentitions, including the incisors, canines, premolars, and first and second molars. The stage‐based method is derived from degrees of dental wear in known‐age (n = 39) and estimated‐age (n = 11) nonadults containing 951 teeth from the predominately 19th century cemetery of Middenbeemster, The Netherlands. The need for such a method is warranted in cases where dental development and/or eruption cannot be assessed for age‐at‐death estimation. As well, by establishing a baseline for normal age‐related nonadult tooth wear, users may better document wear that could be due to extramasticatory behaviours. The regression analysis reveals a strong quadratic correlation—F(2, 47) = 555.1, p < .001, R2 = .95, standard error of the estimate = 1.14, residual sum of squares (RSS) = 68.89, predicted residual error sum of squares (PRESS) = 77.67—between age and wear and multivariate adaptive regression splines (R2 = .95, generalised cross validation = 1.67, RSS = 67.68, PRESS = 89.34), which are used to develop an R‐package that users may employ to estimate age‐at‐death from dental wear. The accuracy of this method (78–98%) is evaluated using leave‐one‐out cross‐validation. Analyses of males versus females, deciduous versus permanent, upper versus lower, and anterior versus posterior teeth revealed no apparent reason to warrant separate methods for these groups of separated dentitions. This method fills a disciplinary gap in the understudied area of deciduous and nonadult dental wear and hopes to stimulate much future research. With the R‐package, we also provide the foundation and framework for the development of additional reference populations across different spatiotemporal contexts, to make the method more widely applicable.  相似文献

The aim of this work is to investigate the potential of wear on the earliest erupting teeth, the deciduous central incisors, for studying weaning in human skeletal populations. The study group is from mediaeval Wharram Percy, where existing δ15N data indicate cessation of breastfeeding occurred by about 24 months post‐partum. The hypothesis tested is that there should be an increase in dental wear as breast milk is replaced with solid foods during weaning. Incisor wear is monitored using crown heights, measured from photographs using image analysis. Results provide little evidence for alteration in incisor wear rates with the attenuation of breastfeeding, perhaps because abrasive foods were used as supplements well before breastfeeding declined.

In 1929, āpirana Ngata published an article titled “Anthropology and the government of native races in the Pacific”. This would appear to confirm the link between anthropology and the rule of indigenous populations in New Zealand and its Pacific empire, but the evidence presented in this article suggests a more complex situation. This paper examines the “empirical anthropology” of Ngata and Peter Buck and the ways in which their activities reshaped the policy and practice of the Department of Native Affairs between 1920 and 1935, particularly through the notion of cultural “adjustments” or “adaptation”. Archival research reveals that behind the activities of the Dominion Museum, the Polynesian Society and its Journal was a Māori-led body, the Board of Māori Ethnological Research, which redirected government collecting, research and publication from salvage to the maintenance and revival of Māori cultural heritage in the service of tribal social and economic development. Seen through the theoretical framework of assemblage theory, we can see how a malleable idea of culture was employed in social governance in quite different ways to the colonial governmentality at work in other settler colonies at this time. The paper argues that this form of “anthropological governance” effectively de-territorialized state institutions, thereby creating a distinctive space for the native exterior to the nation.  相似文献

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

Reliable ageing techniques for wild animals are notoriously challenging to develop because of the scarcity of sizeable collections of known‐age specimens. Without such techniques it is difficult to reconstruct hunting patterns, which is a significant problem for the examination of assemblages from pre‐farming cultures. This paper presents a new method, based on mandibular tooth eruption and wear, for assessing the age of fallow deer. The method was developed from a large collection (n = 156) of known‐age Dama dama specimens, has been blind tested by members of the zooarchaeological community and represents a user‐friendly system with the potential to generate large compatible datasets through which the dynamics of human–Dama relationships can be examined.

This paper provides a critical review of recent geographical scholarship on place naming and contends that aural aspects of naming have yet to be fully worked into the research agenda. To begin to address this gap in the literature, we consider pronunciation to be an important element of the cultural politics of place naming within post-colonial societies. In asserting links between speaking and naming we are contributing to recent scholarship in cultural geography that has moved beyond the visual to consider a wider sensory spectrum in the constitution of place. Our case material is drawn from Aotearoa/New Zealand where conservative reactions to sympathetic pronunciations of Maori names by media personalities are a frequent occurrence. By way of example, we interpret selected examples of unsolicited comment gleaned from newspapers during the period 1994-1999. We conclude that identity is at least in part narrated through place-referenced linguistic tactics such as pronunciation. Cet article se veut un inventaire critique des récents travaux académiques sur la toponymie et soutient que la question des aspects 'auditifs' du nom mérite davantage l'attention des chercheurs. Afin de remédier à ce manque dans la littérature existante, nous suggérons que la problématique de la prononciation constitue un élément important des débats culturels entourant l'attribution de noms de lieux, surtout chez les sociétés postcoloniales. En insistant sur les liens entre le fait de parler et celui de nommer, notre discussion s'inscrit dans les travaux récents en géographie culturelle allant au-delà du visuel afin de concevoir une gamme sensorielle beaucoup plus large en ce qui a trait à la conception du lieu. Nos données sont tirées de la Aotearoa/Nouvelle-Zélande où les réactions conservatrices sont fréquentes lorsque des noms d'origine Maori sont utilisés par des personnalités médiatiques. A titre d'exemple, nous interprétons des commentaires receuillis dans les journaux entre 1994-1999. Nous concluons que l'identité est en partie rattachée à des références toponymiques et linguistiques tactiques telles que la prononciation. Este papel da un análisis crítico de reciente erudición geográfica sobre el nombramiento de lugares y afirma que el aspecto auditivo del nombramiento todavía no forma uno de los asuntos de investigación. Para empezar a cerrar esta brecha en la literatura, consideramos que la pronunciación constituye un elemento importante en la política cultural del nombramiento de lugares dentro de las sociedades pos-coloniales. Al acertar vínculos entre el hablar y el nombrar contribuimos a erudición reciente en la geografía cultural que se ha ido más alláde lo visual para considerar un espectro sensorio más amplio en la constitución de lugar. La materia de nuestro estudio viene de Aotearoa/Nueva Zelanda donde son frecuentes las reacciones conservadores a pronunciaciones comprensivas de los nombres Maorí por personajes de los medios de comunicación. Como ejemplo, interpretamos ejemplos de comentarios no solicitados, recogidos de periódicos de los años 1994 a 1999. Concluimos que, por lo menos en parte, la identidad es narrada por tácticas lingüísticas que se refieren a un lugar, tal como pronunciación.  相似文献
