Study Notes
Tooth Development
- Ectomesenchymal cells surrounding the dental papillae and connective tissue form the dental follicle during tooth development.
- The inner enamel epithelium during the early bell stage of tooth development is represented by the inner enamel organ.
- Ameloblasts become star-shaped with elongated cytoplasmic processes in the enamel organ during tooth development.
- The central cells along the concave surface of the enamel organ differentiate into ameloblasts.
- During the early bell stage, peripheral cells appear as cuboidal and are known as the outer enamel epithelium.
- Polygonal cells located between the outer and inner enamel epithelium in the advanced cap to early bell stage of tooth development undergo apoptosis.
- The enamel knot acts as a signaling center.
- The epithelial cells of the enamel organ derive their nutrients from the surrounding ectomesenchymal tissue.
- Permanent successors for anteriors arise from the lingual extension of the lamina during the early bell stage.
- The formation of the enamel knot begins the late bell stage of tooth development.
- The enamel organ precedes amelogenesis and enamel formation at the incisal edges and cusp tips.
- Permanent premolars and molars arise from the dental lamina.
- The inner enamel epithelium gives rise to enamel tissue during tooth development.
- The differentiation of ameloblasts and enamel formation proceeds coronally and cervically on all tooth surfaces during the late bell stage.
- The Hertwig Epithelial Root Sheath (HERS) outlines the root shape during tooth development.
- Root formation begins with the formation of the HERS.
- The dental papilla induces odontoblasts to produce dentine during tooth development.
- The differentiation of ameloblasts and enamel formation starts at the cervical loop.

Description
Test your knowledge on the development of teeth from advanced cap to early bell stage. Learn about the progression from the dental lamina towards the developing enamel organ and the formation of the dental sac. Based on content from 'Ten Cate's Oral Histology, Development, Structure and Function, 8th Edition'.
