Study Notes
Tooth Development
- Ectoderm turns into ameloblasts during tooth development, which will form the enamel.
- Neural crest cells originate from the neural crest and migrate to the oral cavity, where they differentiate into odontoblasts, cementoblasts, and osteoblasts.
- Ameloblasts, derived from ectoderm, will form the enamel during tooth development.
- Dental lamina, a transient epithelial structure, guides the formation of tooth buds and eventually disappears, leaving the tooth germ behind.
- Initiation of dental lamina occurs during the 6th-7th week of intrauterine life.
