Abstract
The aim of this article is to describe the composition of the Tooth Fairy collection (collection Petite souris as it is known in French), a documented sample of deciduous teeth from individuals with known kinship curated at the University of Bordeaux (France). Since 2014, we have collected naturally exfoliated deciduous teeth from French children of known kinship and life histories. The life-history records include date and place of birth, sex, birth weight, and length, weight measurements during the first 6 months of life, whether the child was born premature or full-term, delivery conditions, and dietary information including weaning age. Data collection and exploitation was approved by the French authority Commission Nationale de l'Informatique et des Libertés. The collection, which is still expanding, is currently composed of 995 deciduous teeth belonging to 99 individuals from 42 families. The sample includes 61 female individuals and 38 male individuals, born between 1953 and 2013, the majority from France. Siblings are the most represented kinship type within the collection. The Tooth Fairy collection of deciduous teeth from individuals with known life history and kinship offers a unique window into the variation in human growth. Available for macro-, meso-, and microstructural analysis, the collection offers new insights into the multiple factors influencing dental growth, human variation, and diet, especially around birth and during early postnatal life. This collection is particularly relevant for studies in forensic, dental, and biological anthropology.
