Tooth formation: Initial stages - development of the dental lamina - neural crest cells migrate into the developing mesenchyme - a basement membrane separates the developing oral epithelium and mesenchyme The initiation of tooth formation starts around the 37 th day of gestation.

CAP STAGE Below this cap is a condensing mass of mesenchyme (ectomesenchyme) – dental papilla – produces the future dentin and pulp tissue. The basement membrane separating the enamel organ and the dental papilla becomes the future site for the dentinoenamel junction (DEJ) • The mesenchyme surrounding the enamel organ is the dental sac
