Abstract

Accounts of dentine microstructure are less well established in the primate life history literature than those of enamel microstructure. The aim of this paper is to draw some basic comparisons between enamel and dentine, but at the same time to show how dentine microstructure can make a major but different contribution to reconstructing past lives than enamel can. Dentine has both an organic and an inorganic component. The organic component contains growth factors, stable isotopes and DNA that survive long after death. The mineral component contains trace elements and preserves an incremental record of tooth growth. These can be used to put a time scale to many past events when the chemistry or microstructure of dentine has become altered during tooth growth. Dentine microstructure allows us to reconstruct tooth root growth in the past and has contributed to a fuller understanding of the modular nature of developing dentitions among hominoids and hominins. / Au sein de la littérature sur l’histoire de vie des primates, il existe moins d’études portant sur la microstructure de la dentine que sur celle de l’émail. Le but de cet article est d’extraire des informations à partir de simples comparaisons entre émail et dentine, tout en montrant combien la microstructure de la dentine peut apporter une contribution majeure et différente de celle de l’émail pour reconstruire la vie passée. La dentine présente à la fois une composante organique et une composante non organique. La composante organique contient des facteurs de croissance, des isotopes stables et de l’ADN qui survivent longtemps après la mort de l’individu. La composante minérale contient des éléments traces et enregistre de manière incrémentale les variations périodiques de la croissance dentaire. Toutes ces informations peuvent être utilisées pour retracer la chronologie de nombreux événements passés lorsque la chimie ou la microstructure de la dentine a altérée au cours de la croissance dentaire. La microstructure de la dentine nous permet de reconstruire la croissance de la racine des dents et contribue à mieux comprendre la nature modulaire du développement dentaire chez les hominoïdes et les homininés.
