During the fifth week of embryonic development, the oral epithelium thickens along the future dental arches to form the dental lamina.

- Dental lamina; is a band of epithelium that has invaded the underlying ectomesenchyme along both the horseshoe-shaped future dental arches.
- Deciduous dentition developed from dental lamina (8th week)
- Successional lamina; lingual extension of dental lamina. Responsible for dev. Of permanent incisors, canines and premolars(5th month intrauterine life)
- Accessional lamina; distal extension of dental lamina. Responsible for dev. Of molars.
- "cell rest of serre" = remnants of dental lamina.
It is a band of epithelium that has invaded the underlying ectomesenchyme along each of the horse shoe shaped dental arches. Dental lamina serve as primordium for deciduous teeth. It is the first formed part during the tooth development.
2-3 weeks after the rupture of the bucopharyngeal membrane, age of embryo being 6 weeks old, certain basal cells proliferate more rapidly and this leads to the formation of the dental lamina.
Permanent molars arise from the distal extension of the dental lamina.
