What is the function of neural crest cells?
Migrate through the body, develop at the time of neural tube closure, form odontoblasts & melanocyes
(does NOT form ameloblasts - oral epithelium tissue derived from ectoderm layer)

- Type I: immediate urticaria/erythema (natural rubber proteins
- Type IV delayed: contact dermatitis (accelerators like carbamate)
What is the red patch of Atherton?
When you move teeth very quickly that epithelial cells can’t grow fast enough –> granulation tissue
