This chapter introduces the morphology and structure of teeth, the basic terms for understanding dental organisation and histology, the different types of human dentition and basic notions about the chronology of their development. The embryonic origin of teeth from the oral epithelium and underlying ectomesenchyma and the processes of tooth crown and root formation are then described in detail. Finally, the molecular mechanisms that occur during odontogenesis and hypotheses on the formation of the dentition pattern are discussed.

摘要

This chapter introduces the morphology and structure of teeth, the basic terms for understanding dental organisation and histology, the different types of human dentition and basic notions about the chronology of their development. The embryonic origin of teeth from the oral epithelium and underlying ectomesenchyma and the processes of tooth crown and root formation are then described in detail. Finally, the molecular mechanisms that occur during odontogenesis and hypotheses on the formation of the dentition pattern are discussed.
