When it is present, the dental lamina connects the developing tooth bud to the epithelium of the oral cavity.

This invagination of ectodermal tissues is the progenitor to the later ameloblasts and enamel while the ectomesenchyme[3] is responsible for the dental papilla and later odontoblasts.

It derived from horseshoe shaped primary epithelial band which is formed when thickened oral epithelium invaginates into the mesenchyme.

[4] A series of epithelial outgrowths deep into mesenchyme due to proliferation on the cranial portion of dental lamina give rise to future spot of deciduous teeth.

[6] On completion of the dentition, the dental lamina is usually destroyed and reabsorbed, but when remnants fail to resorb, it can continue to proliferate abnormally.
