Age estimation of nonadult skeletons from archaeological or forensic contexts has relied heavily on modern schedules of dental formation developed on samples of children of affluent populations. Although genetic factors have been considered to have had the greatest influence on population differences in dental development, increased interest has been placed on the role of environmental influences, such as differences in socioeconomic status and secular trends. This study evaluates the quality (i.e., accuracy and reliability) of two Bayesian dental age estimation methods to a sample of identified child skeletons from the Lisbon collection (20th century Portugal). The two Bayesian methods are developed on a reference sample of modern children from France, Ivory Coast, Iran, and Morocco. The test sample from Lisbon, compared to the reference sample, is separated by over 50 years of secular trends and comprises a lower socioeconomic segment. The two Bayesian methods show that the Lisbon children are consistently 1-year behind in dental age compared to the modern children of the reference sample. Environmental factors largely explain the differences between dental and chronological age in historic samples of nonadults.

ObjectivesThe purpose of this article is to examine the impacts of physical and structural violence on the well‐being of early modern enslaved Africans by comparing the growth of children in an archaeological sample recovered from Lagos, Portugal with that of modern children known to have lived under socially oppressive and racist political regimes.Materials and methodsThe age of 18 individuals was estimated from the length of developing teeth. Long bone lengths for age in the enslaved African sample were compared with two black juvenile known age samples: the Raymond Dart (South Africa) and Hamann‐Todd (United States) collections. Z‐scores were calculated for all samples using black children in the South Africa Long Bone (SALB) database as the reference. The similarity of growth across the samples was tested and skeletal growth profiles (SGPs) were devised for the three samples.ResultsThe children in the Lagos, Raymond Dart, and Hamann‐Todd samples were all small for age compared to the SALB reference. While children in the Dart sample tended to be the smallest for age and in the Hamann‐Todd the largest, with the children in the Lagos sample falling between them, the three samples did not show significant differences in growth status.DiscussionThe growth deficits shown in this study demonstrate the severe impacts of physical and structural violence on the lives of these children. Although uncertainty remains regarding the timing of growth insults relative to arrival, slavery in Portugal as materialized in these individuals was as violent as in other countries.
