Development of Tooth - Part 1 (Morphological stages- dental lamina)
Doctoropsy・4 minutes read
Tooth development is a complex process starting in utero, with the Dental Lamina playing a crucial role in the formation of deciduous and permanent teeth, including the succedaneous teeth and 3rd molars, which begin development at 5 years of age.
Insights
- The Tooth development process begins in utero, with the oral ectoderm playing a crucial role in determining the future dental arch position through structures like the Dental Lamina and Vestibular Lamina.
- The formation of the Dental Lamina not only leads to the development of deciduous teeth but also plays a significant role in the creation of permanent molars and succedaneous teeth, showcasing the intricate and interconnected nature of tooth development from early embryonic stages to childhood.

Tooth development from utero to adulthood
- Tooth development is a complex process starting in utero, with the oral ectoderm lining the primitive oral cavity at 6 weeks of embryonic life.
- The Primary Epithelial Band, formed by basal cells of the oral ectoderm, determines the future dental arch position, giving rise to the Dental Lamina and Vestibular Lamina at 7 weeks.
- The Dental Lamina, a horse-shoe shaped plate, leads to deciduous teeth development and later gives rise to permanent molars through distal extensions.
- The Dental Lamina also forms the Successional Lamina, leading to succedaneous teeth development, with the last tooth, the 3rd molar, starting its development at 5 years of age.
