Study Notes
Tooth Development Stages
- The enamel organ forms during the bell stage of tooth development.
Dental Papilla
- The dental papilla is a mass of mesenchymal tissue located beneath the enamel organ, playing a critical role in tooth formation.
Function of the Dental Follicle
- The dental follicle supports the development of the tooth by surrounding the enamel organ and dental papilla, eventually contributing to periodontal ligament, cementum, and alveolar bone formation.
Formation of Dentin
- The first dentin to be formed during tooth development is called mantle dentin, setting the foundation for subsequent dentin layers.
Unmineralized Dentin Matrix
- The layer of dentin matrix immediately adjacent to odontoblasts that remains unmineralized is known as predentin.
Changes to the Dental Papilla
- After dentin formation during the late bell stage, the dental papilla differentiates into dental pulp, providing vital support and nourishment to the developing tooth.
