During tooth histogenesis, ectomesenchyme influence the growth of oral epitheliums to create the tooth germ. What stage of tooth development is this?
  1. Stage 1
  2. Stage 3
  3. Stage 6
  4. Stage 2
Explanation
Answer: A - During tooth histogenesis, ectomesenchyme influence the growth of oral epitheliums to create the tooth germ in stage one. The development continues to the elongation of inner enamel epithelial cells of the enamel organ. Differentiation of odontoblasts and the deposition of the first layers of dentin and enamel complete stage three through five. The final stage consists of root dentin and cementum.
