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…

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
You are not what you eat during physiological stress
Variation in δ 13 C and δ 15 N values can be assessed to understand not only diet, but also the influence of physiological factors on an individual. The metabolic balance of an individual can impact isotopic signals in tissues that are forming during the periods of metabolic stress. Fluctuating δ 15 N values are associated with physiological stressors that alter an individual's metabolism such as infection, injury, or pregnancy. This study examin…
