“…Esto indicaría una baja fiabilidad de los modelos obtenidos, siendo el valor de R2 mayor en el análisis de regresión para el canino inferior izquierdo. Si bien estudios similares han reportado altos coeficientes de determinación para este método (Cameriere et al, 2004;De Luca et al;Cameriere el at., 2012a;Fabbri et al), otros reportes, como el de Anastácio et al, mostraron valores bajos en los resultados obtenidos. Cabe mencionar que, con frecuencia, el coeficiente R2 puede dar una idea equivocada de las capacidades predictivas del modelo de estimación propuesto, ya que representa exclusivamente un coeficiente con capacidades explicativas de este (Martínez Rodríguez, 2005).…”

“…El método de Cameriere et al (2004), ha sido previamente aplicado en muestras poblacionales de países como Italia (Fabbri et al, 2015), Portugal (Cameriere et al, 2013), México (De Luca et al, 2011), India (Jeevan et al, 2011), Brasil (Azevedo et al, 2015), entre otros, existiendo interés por la aplicación y validación según el contexto poblacional. Por lo mencionado anteriormente, el objetivo de este estudio fue desarrollar modelos de regresión lineal para la EE mediante la relación de área pulpa/diente (Cameriere et al, 2004) en caninos y premolares mandibulares, utilizando ortopantomografías (OPGs) en una población chilena de individuos adultos de edad y sexo conocidos.…”

“…So that, other methods have to be used to estimate age by radiological determination. The reduction in size of the pulp cavity resulting from a secondary dentine deposition, which is proportional to the age of the individual, is one age predictor measurable in dental radiographs and tomographs as an alternative to more invasive methods [80][81][82][83][84]. In literature, two methods have been used:…”

Post Mortem Examination and Autopsy - Current Issues From Death to Laboratory Analysis

Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. Visual, radiographic, chemical and histological techniques can be used for dental age estimation. Visual method is based on the sequence of eruption of the teeth and morphological changes that are caused due to function such as attrition, changes in color that are indicators of aging. Radiographs of the dentition can be used to determine the stage of dental development of the teeth from initial mineralization of a tooth, crown formation to root apex maturation. Histological methods require the preparation of the tissues for detailed microscopic examination. The chemical analysis of dental hard tissues determines alterations in ion levels with age, whereas the histological and chemical methods are invasive methods requiring extraction/sectioning of the tooth. In this chapter, the different techniques and considered studies were overviewed in conjunction with their advantages and disadvantages. It needs to be taken into consideration that rather than restricting on one age estimation technique, using the other available techniques additionally and performing repetitive measurements may be beneficial for accurate age estimation.

“…As mentioned above, many proposed and widely used adult age‐estimation methods rely on visual assessment of macroscopic features and qualitative scoring protocols. However, as have been described in AJPA , there are quantitative alternatives based on osteon remodeling (Chan, Crowder, & Rogers, ; Ericksen, ; Kerley, ; Kerley & Ubelaker, ; Stout & Paine, ; Turner‐Walker & Mays, ), root dentin translucency (Drusini, Calliari, & Volpe, ), reduction of the coronal pulp cavity because of the formation of secondary dentin (Drusini, Toso, & Ranzato, ; Fabbri et al, ), and tooth‐cementum annulations (cementochronology) (Charles, Condon, Cheverud, & Buikstra, ; Condon, Charles, Cheverud, & Buikstra, ; Naylor, Miller, Stokes, & Stott, ; Wittwer‐Backofen, Gampe, & Vaupel, ). Osteon remodeling approaches, for example, based on the number of intact and fragmentary osteons and other parameters visible in thin sections of bone can be applied to fragmentary remains for which macroscopic features cannot be evaluated.…”

K E Y W O R D S : enthnographic census, life tables, paleodemography, population models 1 | I N TR ODU C TI ON Demography is the study of population dynamics. The primary foci of demography are rates and levels of mortality, fertility, and migration and how these all interact to produce population growth (or decline), density, and age-and sex-structures; how these rates or levels vary across time and space and what produces such variation; and what consequences these have on other aspects of human (or nonhuman) existence. These demographic phenomena lie at the very heart of evolution. Natural selection occurs as a result of differential fertility and mortality within a population; gene flow occurs because of migration between populations; and the effects of genetic drift are dependent upon population size, which is an outcome of the interactions among mortality, fertility, and migration (Gage, DeWitte, & Wood, 2012).These demographic forces also affect, are affected by, and reflect many of the things that anthropologists find most interesting. For example, the age-sex structure of a population influences the population's ratio of consumers to producers and numbers of potential marriage partners, and thus places limits on such things as subsistence strategies and household structure. The age-sex structure of a population can also significantly influence economic relationships among families and communities, as cultures often have inheritance and habitation rules that depend on the sex and sometimes age of individuals, and thus are inherently influenced strongly by demographic structure. Population growth and density affect socio-political structures and shape disease ecologies, which can, in turn, affect demographic rates and drive biological and cultural adaptations. Sociocultural phenomena also have the potential to powerfully shape demography. For example, warfare can have short-and long-term effects on sex ratios or age structures (as in the case of the post-World War II baby boom). Sexselective infanticide and abortion, and withholding of resources or medical care from daughters because of cultural preferences for sons affects sex ratios. Economic policies and warfare influence patterns of migration. Ultimately, demography is relevant to all fields of anthropology, whether or not all anthropologists are interested in demography itself and its effects on other aspects of human life. Although, as can be seen in the pages of the American Journal of Physical Anthropology, numerous anthropologists over the last 100 years of the journal's existence have been explicitly interested in demography, and in demographic anthropology in particular. In contrast to national demography, which primarily focuses on large datasets (often derived from censuses) from European and other industrialized populations, demographic anthropology typically focuses on relatively small, nonindustrial populations from which data are collected as a part of ethnographic fieldwork. Demographic anthropology also examines the demography of populat...

Radiological tooth/pulp ratio in canines and individual age estimation in a sample of adult neolithic skeletons from Italy

Abstract: This finding may support the hypothesis that individuals aged 50+ are rare in prehistoric skeletal samples due to the unreliability of classical anthropological methods, not only because they were actually rare in prehistoric populations, or absent for taphonomical reasons.
