Developmental anatomy

DEVELOPMENT OF TOOTH

• The enamel develops from epithelium lining of the buccal cavity of the embryo.
• Ameloblasts of the enamel organ form enamel for the developing tooth.
• Lining the pulp cavity are specially modified connective tissue cells called odontoblasts and their function is the production of dentine.
• A thin layer of bony tissue or cementum later forms on the outer surface of dentine around the root of the tooth.
• The dentine, cementum and pulp are derived from the mesenchyme.
