Microstructural Evidence for Early Childhood Stress in a Community in Transition at Hisban, Jordan
Heterogeneity in experiences of vitamin D deficiency in an early to mid-19th century population from Montreal, Quebec
OBJECTIVE: To use the prevalence of prenatal/infancy interglobular dentine (IGD) as a proxy for suboptimal vitamin D status and explore its link to mortality, biological sex, cultural behaviours and environmental factors during the end of the pre-industrial/ beginning of the industrial period. MATERIALS: 50 skeletons from the St. Antoine cemetery (1799-1854), Montreal, Quebec with a well-preserved first mandibular molar. METHODS: Thin sections we…
Using teeth as tools
OBJECTIVES: With a growing interest in the mother-infant dyad and the Developmental Origins of Health and Disease hypothesis among biological and medical anthropologists, this study set out to provide all the information required to evaluate if mineralization defects in dentine might be caused by vitamin D deficiency in the critical first 1000 days of life. MATERIALS AND METHODS: Information was compiled on dentine formation in utero to approxima…
Micro‐CT assessment of dental mineralization defects indicative of vitamin D deficiency in two 17th–19th century Dutch communities
OBJECTIVES: This study investigates vitamin D deficiency patterns in individuals from birth to the beginning of adolescence. Microscopic computed tomography (micro-CT) evaluation of interglobular dentine (IGD) in teeth provides information on the age of disease onset and the number of deficient periods per individual, which will increase our understanding of factors influencing vitamin D deficiency prevalence, including sociocultural practices an…
Mobility and rickets
The aims of this study are twofold: first, to consider Vitamin D deficiency during two periods of growth and, second, consider Vitamin D deficiency with respect to evidence for migration and mobility in a skeletal assemblage (n = 169) from Aventicum, Roman Switzerland (first to third century CE). Vitamin D deficiency was evaluated macroscopically, and individuals with evidence of Vitamin D deficiency (n = 3) were assessed histologically for inter…
The rachitic tooth
Micro-computed tomography of teeth as an alternative way to detect and analyse vitamin D deficiency
Age estimation in older adults
OBJECTIVES: Accurate age estimates are foundational for bioarchaeological research, yet the ability to accurately age older adult skeletons remains elusive. This study uses a new version of pulp/tooth area calculations to investigate chronological age of older archaeological individuals. MATERIALS AND METHODS: Pulp/tooth area ratios were calculated on modern control teeth (n = 10) that were first radiographed and then sectioned for comparative an…
Ancient Vitamin D Deficiency
Vitamin D deficiency is now widely recognized as one of the most common health conditions in the world, with important consequences for overall health. Levels of deficiency appear to be rising, but the extent to which past humans were affected by vitamin D deficiency and the roles of this hormone in past human health are currently unknown. The discovery that mineralization defects in tooth dentin reflect periods of deficiency and are preserved in…
The rachitic tooth
Sexual dimorphism of the dental tissues in human permanent mandibular canines and third premolars
Methods of measuring tissue area from images of longitudinal thin tooth sections have been used to assess sexual dimorphism in the permanent dentition. The aim of this study was to demonstrate the extent of sexual dimorphism within the coronal tissue proportions of permanent mandibular canines and premolars, using area measurements of the enamel and dentine‐pulp core. The sample consisted of embedded “half‐tooth” sections from 45 individuals, all…
